                               DECISION ON ENTITLEMENT1

       On November 6, 2015, Marsha Dougherty (“Petitioner”) filed a petition pursuant to the
National Vaccine Injury Compensation Program.2 Petitioner alleged that she developed
narcolepsy with cataplexy as a result of the influenza (“flu”) vaccine she received on November
7, 2012. Pet., ECF No. 1.

        The undersigned held an entitlement hearing in this matter on November 30 through
December 1, 2017, in Boston, Massachusetts. After considering the record as a whole, and for
the reasons explained below, the undersigned finds that Petitioner failed to show that her
condition was caused by the flu vaccine, and is therefore not entitled to compensation under the
Vaccine Act.

1
 This decision shall be posted on the United States Court of Federal Claims’ website, in
accordance with the E-Government Act of 2002, 44 U.S.C. § 3501 note (2012) (Federal
Management and Promotion of Electronic Government Services). In accordance with Vaccine
Rule 18(b), a party has 14 days to identify and move to delete medical or other information that
satisfies the criteria in § 300aa-12(d)(4)(B). Further, consistent with the rule requirement, a
motion for redaction must include a proposed redacted decision. If, upon review, the
undersigned agrees that the identified material fits within the requirements of that provision, such
material will be deleted from public access.

 National Childhood Vaccine Injury Act of 1986, Pub L. No. 99-660, 100 Stat. 3755.
Hereinafter, for ease of citation, all “§” references to the Vaccine Act will be to the pertinent
subparagraph of 42 U.S.C. § 300aa (2012).
         I.   Procedural History

        Petitioner filed her petition on November 6, 2015. Pet. Later that same day, the case was
assigned to Special Master Hamilton-Fieldman. Not. Assignment, ECF No. 4. Petitioner filed
her medical records over the subsequent several months. See ECF Nos. 6-19. On March 28,
2016, Respondent submitted his Rule 4(c) Report, arguing that Petitioner had failed to establish
that the flu vaccine caused her narcolepsy with cataplexy. ECF No. 20 at 7-8. Petitioner
submitted an expert report authored by Dr. Marcel Kinsbourne on October 13, 2016. Pet’r’s Ex.
12, ECF No. 36.

       The case was reassigned to the undersigned on January 12, 2017. ECF No. 45. On
February 8, 2017, Respondent submitted responsive expert reports by Dr. Thomas Scammell and
Dr. Andrew MacGinnitie. Resp’t’s Exs. A, C, ECF Nos. 47-1, -2. Petitioner then submitted a
supplemental expert report by Dr. Kinsbourne on March 21, 2017. Pet’r’s Ex. 16, ECF No. 54-1.
Respondent replied on April 18, 2017 with a second report from Dr. MacGinnitie. Resp’t’s Ex.
RR, ECF No. 58-1. On May 18, 2017, the undersigned scheduled a two-day entitlement hearing
for September 21 and 22, 2017. Pre-Hearing Order, ECF No. 61. The parties submitted their
pre-hearing briefs and outstanding medical literature over the ensuing months. ECF Nos. 66-82.

        On September 18, 2017, Petitioner filed a Motion to Continue the Hearing for thirty days.
Mot. Continuance, ECF No. 83. Petitioner requested this continuance in order to submit an
expert report addressing an epidemiological study that examined “the occurrence of narcolepsy
after the influenza vaccines used in the United States that contained the influenza
A(H1N1)pdm09 virus strain” authored by Johnathan Duffy, MD, MPH, et alia. See Pet’r’s Ex.
23; Jonathan Duffy et al., Narcolepsy and influenza A(H1N1) pandemic 2009 vaccination in the
United States, 83 Neurology 1832 (2014) [hereinafter referred to as “Duffy”]. The study,
Petitioner explained, was used by Special Master Corcoran in McCollum,3 issued on September
15, 2017, to dismiss a case that also relied upon the theory of causation that Petitioner asserts
here. Id. The undersigned granted the continuance and rescheduled the hearing to take place in
Boston, Massachusetts from November 30 to December 1, 2017. Hearing Order, ECF No. 87.
Petitioner submitted the expert report of Dr. Stanley Young and a supplemental report from Dr.
Kinsbourne on October 24, 2017. Pet’r’s Exs. 52, 53, ECF Nos. 89, 90. Respondent submitted a
supplemental report from Dr. MacGinnitie on November 17, 2017. Resp’t’s Ex. WW, ECF No.
92. The undersigned held the entitlement hearing on the scheduled dates, and this matter is now
ripe for a decision.

        II.   Factual Background

                  a. Medical Records

       Petitioner’s medical history prior to her receipt of the Fluzone vaccine includes
complaints of abdominal pain, migraines, anxiety, hypertension, and neck pain. See Pet’r’s Ex. 2
at 239-62. Petitioner was treated for these conditions by Dr. Cory Neumann, her primary care

 McCollum v. Secretary of Health and Human Services, No. 14-790V, 2017 WL 5386613 (Fed.
Cl. Spec. Mstr. Sept. 15, 2017).

                                                2
provider at Logansport Memorial Physicians’ Office. Id. Petitioner also underwent neck and
spine surgery following an accident while driving an all-terrain vehicle in October 2008. Pet’r’s
Ex. 2 at 24; Pet’r’s Ex. 6 at 13, ECF No. 13-1. Following this accident, Petitioner suffered from
chronic neck pain and was prescribed hydrocodone4 for pain management. See generally Pet’r’s
Ex. 2. Petitioner was also prescribed metoprolol5 and triamterene6 for her hypertension and
Zoloft for anxiety. Pet’r’s Ex. 2 at 236-44. Petitioner began taking Imitrex7 on March 29, 2010
to treat her migraines. Pet’r’s Ex. 2 at 17.

        Petitioner received the seasonal flu vaccine Fluzone on November 7, 2012. Pet’r’s Ex. 2
at 118, 237; see also Pet’r’s Ex. 7 at 6, ECF No. 16-1 (VAERS Report). On that date, Petitioner
visited Dr. Neumann with complaints of neck pain, anxiety, and hypertension. Pet’r’s Ex. 2 at
236. Petitioner stated that she needed stronger pain medicine for her neck pain. Id. Dr.
Neumann recorded that Petitioner’s anxiety waxed and waned, but that this change would be
expected due to the multiple stressors in Petitioner’s home. Id. Dr. Neumann increased
Petitioner’s hydrocodone prescription for her neck pain, and re-filled her Zoloft prescription. Id.
at 237.

        On December 4, 2012, Petitioner visited Dr. Neumann’s office for “complaints of
worsening fatigue.” Pet’r’s Ex. 2 at 232. Petitioner saw Tara Hughes, a nurse practitioner, and
reported tiredness upon waking, despite sleeping for six to eight hours the previous night. Id.
Petitioner noted to Ms. Hughes that she had to pull over on her way to work that day and sleep in
the car because “[s]he feels like she can’t keep her eyes open.” Id. Petitioner also complained of
some chest pain. Id. Ms. Hughes had Petitioner stop the metoprolol, and check back in two to
three days. Id. at 234.

4
  Petitioner was prescribed the brand-name medication Lortab, containing hydrocodone and
acetaminophen, for her neck pain. See generally Pet’r’s Ex. 2. Her medical records refer to both
Lortab and Hydrocodone for this medication. See id. Unless specified in the record as “Lortab,”
the undersigned will refer to this medication as Hydrocodone.

                                                 3
        On January 11, 2013, Petitioner returned to Dr. Neumann to follow up on her complaints
of fatigue. Pet’r’s Ex. 2 at 229. Petitioner reported that she wakes up “not rested” in the
morning and has had to “pull over when she’s driving because she’s so drowsy.” Id. Dr.
Neumann wrote that a sleep study may be needed to determine the cause of Petitioner’s
drowsiness. Id. Dr. Neumann also reported that there is a “significant amount of stress in
[Petitioner’s] life which she may or may not recognize.” Id. Dr. Neumann ordered a sleep study
for Petitioner, advised her to stop taking Zoloft, and prescribed Lexapro for Petitioner’s anxiety.
Id. at 230. Dr. Theodore Nukes performed the sleep study at the Logansport Memorial Hospital
on January 29, 2013. Id. at 144. Dr. Nukes noted that Petitioner’s current medications included
Zoloft, Lortab, triamterene, and a vitamin D supplement. Id. The study revealed “moderate mild
to moderate obstructive sleep apnea (“OSA”).” Id. at 144.

        On April 17, 2013, Petitioner presented at Dr. Neumann’s office for a two-month follow-
up. Pet’r’s Ex. 2 at 225. Petitioner requested to switch her migraine medication due to the cost,
and Dr. Neumann noted that Petitioner’s migraines “are really not any better.” Id. Dr. Neumann
also wrote that Petitioner “also has a lot of stress at home with both the mother and mother-in-
law at home.” Id.

        On August 29, 2013, Petitioner saw Dr. Neumann to discuss her drowsiness “over the last
couple days,” and an “episode” that happened the day before. Pet’r’s Ex. 2 at 220. Petitioner
stated that she “passed out yesterday” while driving and “almost hit a telephone pole.” Id.
Petitioner also said that she has had “staring episodes.” Id. Petitioner told Dr. Neumann that she
has never had any seizures or “shaking activity.” Id. Dr. Neumann recorded that Petitioner was
supposed to see a neurologist six months ago, but “she seemed to improve” and did not visit a
neurologist. Id. Under “Assessments,” Dr. Neumann labeled Petitioner’s diagnoses as syncope
and seizure. Id. at 221. Dr. Neumann ordered labs, and referred Petitioner to Dr. Virginia
Hemelt for neurology. Id.

        Petitioner saw Dr. Virginia Hemelt on September 10, 2013 for “black outs.” Pet’r’s Ex. 6
at 13. Dr. Hemelt recorded that Petitioner’s symptoms began “around January 2008 [when] she
was falling asleep while driving.” Id. Petitioner described an episode to Dr. Hemelt that
occurred “[a] few months ago, [while Petitioner] was driving home around 4-5 [PM] from
work.” Id. Petitioner stated that she lost consciousness and realized when she awoke that the car
was “still moving, and she was in the ditch moving toward a telephone pole.” Id. Petitioner
stated that she was able to avoid the pole, but that she had experienced staring episodes the next
day. Id. Petitioner described vivid dreams and “episodes when her legs have given out.” Id.
Petitioner’s husband described to Dr. Hemelt “periods of time when [Petitioner] acts differently.”
Id. He stated that these periods occurred “while golfing, shopping, and watching TV.” Id.
Petitioner’s husband continued that “[t]here have been times when she is confused and cannot
follow a football game[,] which is a passion for her.” Id.

        Dr. Hemelt recorded that Petitioner is a district manager for Frito-Lay and travels for her
job. Id. Dr. Hemelt found that Petitioner’s “[e]pisodes of altered awareness [are] likely due to
disordered sleep and maybe medication effect from topiramate [Topamax].” Id. at 15. Dr.
Hemelt also wrote in Petitioner’s record that “[t]here is also [a] non-physiologic component of

                                                 4
her exam, which may be benign embellishment.” Id. Dr. Hemelt did not rule out that
Petitioner’s sleep disorders could be due to snoring and mild OSA, “or a combination of those
and narcolepsy.” Id. Dr. Hemelt recommended for Petitioner to undergo a polysomnograph8
and Multiple Sleep Latency Test9 (“MSLT”), and recommended to taper off of Topamax. Id.
Dr. Hemelt continued Petitioner’s prescription for Lexapro. Id.

        On September 12, 2013, Petitioner saw Dr. Kraft in the Logansport Memorial Hospital
Emergency Department. Pet’r’s Ex. 2 at 128. Petitioner went to the emergency room following
“[two] trance-like seizures” she had earlier that day for approximately three minutes each. Id.
Petitioner reported that her first “seizure” occurred two weeks prior. Id. Dr. Kraft ordered a CT
scan of Petitioner’s head, which returned normal. Id. at 129; Pet’r’s Ex. 6 at 11. Dr. Kraft gave
Petitioner a prescription for lorazepam,10 increased her Topamax prescription, and advised
Petitioner to call Dr. Hemelt’s office tomorrow to “expedite the needed work-up for seizures.”
Pet’r’s Ex. 2 at 129-30. Petitioner was discharged the same day. Id. at 129.

         On September 13, 2013, Petitioner underwent a polysomnograph after a referral from Dr.
Hemelt. Pet’r’s Ex. 3 at 2; Pet’r’s Ex. 6 at 4, ECF No. 13-1. The polysomnograph report noted
that Petitioner was taking hydrocodone, Nasonex, Symbicort, Lexapro, Topamax, and lorazepam
at the time. Pet’r’s Ex. 3 at 2. The study revealed a diagnosis of mild sleep apnea and possible
restless legs syndrome. Id. Nasal CPAP therapy was indicated, along with further evaluation
“by means of a formal sleep medicine consultation . . . .” Id. Petitioner had a sleep onset latency
of 7.8 minutes, with REM latency of 151 minutes. Id.

  A polysomnograph is a sleep study used to monitor a patient’s sleep throughout a night.
Mosby’s Manual of Diagnostic and Laboratory Tests 1124 (5th ed. 2014) [hereinafter
“Mosby’s”]. “This more simplified test includes the electrocardiogram (EKG), chest impedance,
airflow monitor, and [oxygen] oximetry . . . . Under audiovisual monitoring the patient is placed
in a comfortable room and sleeps.” Id. During sleep, physicians gather data; “[t]he various
stages of sleep architecture are determined by the EEG [electroencephalogram], and the
physiologic changes during each stage are documented.” Id.
9
  An MSLT takes place during the day after a polysomnograph. Mosby’s 1124. “The MSLT is a
measure of the patient’s ability to sleep during a series of structured naps.” Id. This test, along
with the multiple wake test, is used “to diagnose narcolepsy that follows a night of inadequate
sleep.” Id. at 1125. During an MSLT, the patient is asked to nap “about every 2 hours
throughout the testing period.” Id. at 1126. Each nap is terminated after twenty minutes, and a
diagnosis of narcolepsy can be made by measuring how quickly a patient enters rapid eye
movement sleep during these naps. Id. at 1125-26.

   Lorazepam, sold under the brand name Ativan, is an antianxiety medication that “has a
tranquilizing action on the central nervous system with no appreciable effect on the respiratory or
cardiovascular systems.” Valeant Pharms. North America LLC, Ativan Medication Guide

                                                 5
        The next day, Petitioner underwent an MSLT. Pet’r’s Ex. 6 at 5. The test revealed that
Petitioner “experienced a rapid sleep onset with each of the [five] [n]aps.” Id. Additionally,
Petitioner entered rapid eye movement (“REM”) sleep in two of the five naps, and “[f]ocal
[s]eizure-like activity was noted prior to the first [n]ap and prior to [n]ap 4.” Id. The report also
noted that Petitioner “took her lorazepam following the first [n]ap.” Id. Ultimately, the
“findings [from Petitioner’s test] are consistent with narcolepsy,” and “idiopathic CNS [central
nervous system] hypersomnolence is less likely to explain the findings seen here.” Id. The
report also noted that “[c]hronic partial sleep deprivation by itself would be insufficient to
explain these findings.” Id.

        On September 17, 2013, Petitioner underwent an electroencephalograph11 (“EEG”),
which showed no epileptiform activity. “In particular,” the study emphasized, “there was no
epileptiform correlation with the clinical event described by patient and husband.” Pet’r’s Ex. 2
at 141. On September 19, 2013, Dr. Hemelt prescribed ten milligrams (“mgs”) of Ritalin12 twice
a day in light of Petitioner’s narcolepsy diagnosis. Pet’r’s Ex. 6 at 17.

        Petitioner returned to Dr. Neumann on September 30, 2013. Pet’r’s Ex. 2 at 218. Dr.
Neumann recorded Petitioner’s recent diagnosis of narcolepsy and that she “is doing a little
better on the Ritalin.” Id. Dr. Neumann wrote in his notes that Petitioner informed him that she
“did some research and discovered that there is a link between the H1N1 flu vaccine and
narcolepsy.” Id. “It is not something I have heard or encountered before[,]” Dr. Neumann
wrote, but “if that’s the case we’ll probably need to report her to the CDC.” Id. Petitioner was
not driving at the time of the appointment, and Dr. Neumann advised her to continue her
medications. Id. at 218-19.

       Petitioner returned to Dr. Hemelt on October 17, 2013. Pet’r’s Ex. 6 at 17. Dr. Hemelt
noted that Petitioner indicates “symptoms started after a flu immunization in the fall of 2012.”
Id. Petitioner also complained to Dr. Hemelt of recurring headaches, happening “almost
everyday.” Id. Dr. Hemelt wrote that her symptoms and sleep tests “are consistent with
narcolepsy,” but Dr. Hemelt was “unaware of an association with flu vaccine at this time.” Id. at
19. Dr. Hemelt noted some improvement for Petitioner with “alerting medication,” but added
Xyrem13 at bedtime and counseled for Petitioner to continue her other medications. Id.

11
  EEGs are used to “identify and evaluate patients with seizures.” Mosby’s 549. During an
EEG, “electrodes are placed on the scalp overlying multiple areas of the brain to detect and
record electrical impulses within the brain.” Id. at 550.

                                                  6
       On November 11, 2013, Petitioner visited Dr. Neumann. Pet’r’s Ex. 2 at 215. Petitioner
“seem[ed] to be doing a little bit better[,] but is frustrated that she is not driving yet.” Id. The
next day, Petitioner returned to Dr. Hemelt for a follow-up. Pet’r’s Ex. 6 at 21. During the
November 11, 2013 appointment, Petitioner stated that the double vision had improved since the
medication change and that her narcolepsy symptoms “are much better.” Id. Dr. Hemelt
released Petitioner to drive and advised her to continue her medication. Id.

        Petitioner began treatment with neurologist Dr. Samiullah Kundi on February 27, 2014,
with a review of medical history and current medication refill. Pet’r’s Ex. 4 at 31, ECF No. 6-3.
One month later, on March 20, 2014, Petitioner returned to Dr. Kundi’s office, complaining “of
worsening sleepiness and excessive daytime sleepiness” and “spells when she has loss of
awareness for a few seconds.” Pet’r’s Ex. 4 at 29. Petitioner reported that she has had “three to
four” of these “spells” since her last appointment with Dr. Kundi. Id. Dr. Kundi recommended
to continue Petitioner’s Xyrem and increased her Ritalin prescription to ten mgs. Id. at 31. Dr.
Kundi also recommended an EEG test to “rule out epileptiform activity.” Id. The EEG,
performed on March 31, 2014, was negative for any indication of seizures. Pet’r’s Ex. 4 at 3,
ECF No. 6-3.

        On May 29, 2014, Petitioner visited Dr. Kundi for a neurological follow-up. Pet’r’s Ex. 4
at 23. Dr. Kundi reported that Petitioner was tolerating the higher doses of Ritalin and Xyrem
prescribed at their last appointment. Id. Dr. Kundi, however, wrote that “[Petitioner] did have a
spell when she was in the restroom,” where “she [dozed] off and hit against [sic] the back of her
neck.” Id. Petitioner reported neck pain since the incident. Id. Dr. Kundi ordered a CT scan on
Petitioner’s neck and ordered refills for her prescriptions. Id. at 24-25. The CT scan revealed
Petitioner’s previous spinal surgeries, but otherwise found “a normal postoperative spine.”
Pet’r’s Ex. 4 at 5.

        On July 24, 2014, Petitioner visited Dr. Kundi to continue her treatment for narcolepsy.
Pet’r’s Ex. 4 at 21. Dr. Kundi recorded that Petitioner described “two small spells of sleep
paralysis without associated loss of consciousness or loss of awareness.” Id. Otherwise,
Petitioner reported that her symptoms had improved on Xyrem and Ritalin. Id. at 22. Dr. Kundi
recommended for Petitioner to continue her medication and follow up in three months. Id.

        On September 22, 2014, Petitioner visited Dr. Neumann. Pet’r’s Ex. 2 at 200. Dr.
Neumann wrote that, “[Petitioner] does have narcolepsy which from a point in time seems to be
right after she got her flu vaccine . . . .” Id. Dr. Neumann advised Petitioner to continue her
medications for narcolepsy and high cholesterol. Id. at 200-01.

       Petitioner returned to Dr. Kundi on October 23, 2014. Pet’r’s Ex. 4 at 18. Dr. Kundi
noted that Petitioner’s “symptomatic improvement” with her current doses of Ritalin and Xyrem
had continued since her last appointment. Id. at 19. Dr. Kundi recommended for Petitioner to
have a second sleep study to investigate her “[a]pneic episodes along with snoring” to determine

diarrhea. Id. at 24. Serious side effects include breathing problems, including sleep apnea, and
mental health problems. Id.

                                                 7
whether she has “underlying sleep apnea.” Id. Dr. Kundi also told Petitioner to continue her
medications and follow up in one month. Id. at 19-20.

        On November 20, 2014, Petitioner returned to Dr. Kundi. Pet’r’s Ex. 4 at 15. Dr. Kundi
recorded that Petitioner was stable on Xyrem and Ritalin. Id. Petitioner reported no recent
episodes of cataplexy. Id. at 16. Dr. Kundi noted that he was waiting for Petitioner to complete
the additional sleep study to determine whether she has sleep apnea, but found Petitioner capable
of driving. Id. at 16-17. Dr. Kundi recommended for Petitioner to continue her current
medications and follow up in two months. Id. at 17.

        On November 25, 2014, Petitioner returned to Dr. Neumann’s office after falling and
hitting her head on the floor. Pet’r’s Ex. 2 at 195. Petitioner recounted that “4-5 days ago,” she
was sitting at the table after taking her evening medication. Id. She then awoke on the floor
with a bloody nose. Id. Petitioner denied any amnesia, confusion, or light sensitivity. Id. The
nurse practitioner on staff ordered a CT scan of Petitioner’s head to see whether she had any
head or facial injury.14 Id. at 196.

        On December 1, 2014, Petitioner underwent another polysomnograph at the behest of Dr.
Kundi. Pet’r’s Ex. 3 at 3. Dr. Jatla Sridhar performed the study at the Howard Specialty
Hospital and recorded Petitioner’s medications as Xyrem, Ritalin, and hydrocodone. Id. The
study revealed moderate sleep apnea, and Dr. Sridhar suggested CPAP therapy, “especially given
the severity of OSA.” Id. Dr. Sridhar did not note any signs of restless legs syndrome and
Petitioner was recommended to practice “cognitive and behavioral techniques to improve sleep
continuity” due to “reduced sleep efficiency.” Id. Petitioner had a sleep onset latency of 4.1
minutes, and REM latency of 104 minutes. Id. Three days later, on December 4, 2013,
Petitioner was seen by an ophthalmologist after a referral by Dr. Hemelt. Pet’r’s Ex. 6 at 12.
Petitioner was diagnosed with “decompensated congenital 4th nerve palsy of the left eye,” but
the physician wrote that “conservative management would likely be beneficial for [Petitioner].”
Id.

       On January 30, 2015, Petitioner visited the neurologist Dr. Hassan Arif after a referral
from Dr. Kundi. Pet’r’s Ex. 4 at 13. Dr. Arif recorded that Petitioner’s symptoms are “about the
same” as when she last saw Dr. Kundi in November of 2014. Id. Petitioner complained of
“daytime headaches and sometimes sleepiness.” Id. Dr. Arif noted that Petitioner was taking
Valium as well as Ritalin at that time. Id. Dr. Arif recommended for Petitioner to see a
pulmonologist to determine whether she has OSA, continue her Xyrem, and to have a follow-up
in two months. Id. at 14.

        On March 10, 2015, Petitioner visited Dr. Francois Abi Fadel for sleep apnea. Pet’r’s Ex.
8 at 2, ECF No. 18-1. Dr. Fadel noted that this was Petitioner’s first appointment for her
diagnosis of OSA. Id. Dr. Fadel counseled Petitioner on the use of her CPAP machine and told
her to follow up in four weeks. Id. at 3.

14
     It does not appear that this CT scan is in the records Petitioner submitted to the Court.

                                                    8
        Petitioner returned to Dr. Arif on April 3, 2015. Pet’r’s Ex. 4 at 10. Petitioner reported
that her symptoms had improved after she began using her CPAP machine. Id. Dr. Arif noted
that Petitioner went to the hospital after she began CPAP therapy due to two consecutive days of
heart palpitations. Id. Dr. Arif advised her to stop taking Ritalin, as her heart palpitations may
be a side effect of the drug. Id. Dr. Arif noted that Petitioner was doing fine without any other
side effects and her “symptoms of tiredness and sleepiness are much improved with the start of
CPAP for obstructive sleep apnea.” Id. at 11. Dr. Arif agreed with Petitioner that she could stop
Xyrem to see “if she needs that medicine.” Id.

        Petitioner returned to see Dr. Fadel on April 21, 2015. Pet’r’s Ex. 8 at 5. Dr. Fadel
recorded that Petitioner was “overall doing well.” Id. Although Petitioner “still has intermittent
daytime sleepiness,” Dr. Fadel wrote, recently she has had “no significant sudden onset [of]
sleep or narcolepsy.” Id. Dr. Fadel noted that Petitioner had stopped taking her Ritalin and
Xyrem, and Petitioner reported that “her daytime fatigue and sleepiness had markedly
improved.” Id. at 5-6. After observing that Petitioner had “excellent compliance” with her
CPAP therapy, Dr. Fadel scheduled a follow-up in six months. Id. at 5-6.

        On July 31, 2015, Petitioner returned to see Dr. Arif. Pet’r’s Ex. 8 at 12. Dr. Arif noted
Petitioner’s new diagnosis of carpal tunnel syndrome and recommended surgery. Id. at 12, 13.
Dr. Arif wrote that Petitioner denied any new medical problems other than carpal tunnel
syndrome, but complained of “some sleepiness and tiredness during the day.” Id. Dr. Arif noted
that Petitioner had previously discontinued her Xyrem and Ritalin due to palpitations, but is back
on Xyrem due to a recurrence of her symptoms. Id. at 13. Dr. Arif wrote that he would consider
Ritalin if there were no improvements in her symptoms and advised her to continue her Xyrem.
Id.

        On September 25, 2015, Petitioner again saw Dr. Arif. Pet’r’s Ex. 8 at 9. Dr. Arif
observed that Petitioner’s “symptoms are not bothering her much,” and that she is on Xyrem
“twice nightly.” Id. Dr. Arif noted that Petitioner’s symptoms have improved with CPAP use,
but she still complained of daytime tiredness. Id. at 10. Dr. Arif started Petitioner on extended-
release Ritalin in the morning, and advised her to continue her other medications, including
hydrocodone and Lexapro. Id.

        On September 28, 2015, Dr. Neumann authored a letter on behalf of Petitioner,
presumably for this case. Pet’r’s Ex. 5, ECF No. 6-4. Dr. Neumann wrote that Petitioner
“started having extreme fatigue and drowsiness with falling asleep while she was driving”
shortly after her November 7, 2012 flu vaccine. Id. “Within four weeks,” Dr. Neumann wrote,
“[Petitioner] called complaining of fatigue which was the start of her complaints that ultimately
was diagnosed as narcolepsy.” Id. It was Dr. Neumann’s opinion that “there is a significant time
correlation concerning the flu shot, i.e. H1N1[,] and the onset of her symptoms.” Id.

        On November 13, 2015, Petitioner saw Dr. Arif for a follow-up regarding her
“narcolepsy and headaches.” Pet’r’s Ex. 8 at 7. Petitioner described her symptoms as “about the
same” since her appointment with Dr. Arif in September of 2015. Id. Petitioner complained of
morning sleepiness and no improvement overall with her symptoms. Id. Dr. Arif wrote that
Petitioner’s symptoms had improved with Xyrem and Ritalin, but she had discontinued them

                                                 9
because she believed her symptoms were due to sleep apnea. Id. at 8. Dr. Arif advised
Petitioner to start Ritalin in the morning for sleepiness and to continue with her Xyrem. Id.
Petitioner was not cleared to drive at this appointment. Id.

        On February 8, 2016, Petitioner returned to visit Dr. Neumann. Pet’r’s Ex. 10 at 6;
Pet’r’s Ex. 15 at 1, ECF No. 53-1. Dr. Neumann observed that Petitioner’s narcolepsy and sleep
apnea were stable, and that she was using her CPAP machine nightly. Id. Petitioner complained
of chronic neck pain and pain in her shoulder. Id. Dr. Neumann noted that her neck pain was
due to a past injury, but that Petitioner could “not remember any injury” to explain her shoulder
pain. Id. Petitioner told Dr. Neumann that the pain “has been worsening over the last few
weeks.” Id. Dr. Neumann ordered a lipid profile to check on Petitioner’s cholesterol and an x-
ray of Petitioner’s shoulder. Id. at 7-8. Dr. Neumann counseled Petitioner to continue her
medication. Id. at 8.

        Petitioner visited Dr. Neumann on April 1, 2016 to discuss “paperwork.” Pet’r’s Ex. 10
at 1, ECF No. 22-1; Pet’r’s Ex. 15 at 5, ECF No. 53-1. Dr. Neumann wrote in his notes that
“[Petitioner] has been fighting with the government concerning vaccine compensation.” Id.
“Apparently,” Dr. Neumann continued, “they recognize idiopathic hypersomnia but don’t
recognize narcolepsy as being caused by the vaccine. There is a fine line between these two
diagnoses.” Id. Dr. Neumann believed that “[Petitioner’s] symptomatology definitely has a time
frame correlation to that vaccine. I don’t see how anyone could prove anything more
conclusive.” Id. He noted that Petitioner has neck pain, “but I don’t believe this has anything to
do with her hypersomnia.” Id. He also noted Petitioner’s previous diagnoses of OSA and high
cholesterol. Id. He advised her to continue Lipitor for her cholesterol and recorded her
depression as stable. Id. He counseled her to continue her medications. Id. at 2-3.

        On April 25, 2016, Dr. Neumann wrote another letter on behalf of Petitioner. Pet’r’s Ex.
9, ECF No. 21-1. He briefly summarized her medical history, and wrote that “[i]t has come to
my attention that apparently narcolepsy is not recognized as a vaccine-related injury.” Id.
“However,” Dr. Neumann continued, “idiopathic hypersomnolence is.” Id. Dr. Neumann wrote
that these disorders are difficult to distinguish, and “are also treated with the exact[ly] similar
regimen.” Id. Dr. Neumann opined that “there is an overwhelming causality from a time frame
standpoint that the H1N1 was responsible for [Petitioner’s] onset of symptoms.” Id. This time
frame “is especially significant,” Dr. Neumann continued, “as she was not having any of these
symptoms and had a very productive career prior to this.” Id. Dr. Neumann concluded that “the
preponderance of the evidence points to a causality from the H1N1 vaccine.” Id.

        Petitioner saw Dr. Fadel on April 28, 2016 for a follow-up for her sleep apnea. Pet’r’s
Ex. 15 at 8. Dr. Fadel noted that Petitioner was “overall doing well from OSA standpoint;
however, [Petitioner is] still having narcolepsy and cataplexy events.” Id. Dr. Fadel wrote that
Petitioner had “excellent compliance” with her sleep apnea treatment regimen and recommended
Petitioner return again in six months. Id. at 9.

       Petitioner reported to Dr. Neumann on May 9, 2016. Pet’r’s Ex. 15 at 11. Dr. Neumann
noted that Petitioner was “doing reasonably on her current regimen.” Id. Petitioner complained
of neck pain, due to “an old accident,” but Dr. Neumann recorded that “[t]he biggest issue is her

                                                10
hypersomnolence.” Id. Her condition “[a]ffects her life and she is unable to work,” Dr.
Neumann continued, “but she is functioning decently at the present time.” Id. Dr. Neumann also
observed that Petitioner’s sleep apnea was stable at the appointment and recommended for
Petitioner to continue her medications. Id. at 11-13.

        On November 3, 2016, Petitioner returned to Dr. Fadel. Id. at 18. Dr. Fadel noted that
Petitioner was “overall doing better since her medications [have] been changed to Xyrem and
Nuvigil.” Id. Dr. Fadel diagnosed Petitioner with post-nasal drip, OSA, and narcolepsy with
cataplexy and advised her to continue her medications and CPAP machine use. Id. at 19.

        On December 14, 2016, a genetic test revealed that Petitioner possesses the gene
associated with narcolepsy, HLA DQB1*06:02. Pet’r’s Ex. 13 at 2, ECF No. 42-1; Pet’r’s Ex.
14 at 1, ECF No. 43-1. Petitioner saw Dr. Neumann for a follow-up appointment on December
28, 2016. Id. at 21. Dr. Neumann noted Petitioner’s history of narcolepsy with cataplexy, OSA,
neck pain, and high cholesterol. Id. Petitioner will be temporarily moving to Wisconsin, Dr.
Neumann wrote, but her conditions are stable. Id. at 21-22.

        On June 13, 2017, Dr. Hemelt authored a letter, stating that Petitioner’s diagnosis of
narcolepsy with cataplexy was confirmed by an overnight polysomnogram in 2013. Pet’r’s Ex.
17 at 2, ECF No. 67-1.

       On August 29, 2017, Petitioner was granted Social Security disability benefits due to her
previous diagnoses of narcolepsy with cataplexy. See generally Pet’r’s Ex. 49, ECF No. 85-1.

       III.    Expert Reports

                   a. Petitioner’s Expert, Dr. Marcel Kinsbourne

        Dr. Kinsbourne received his medical degree at Oxford University in England and is board
certified in pediatrics. Kinsbourne Curriculum Vitae (“Kinsbourne CV”) 1-2, ECF 80-1. He
first became licensed in 1955 in the United Kingdom and subsequently obtained medical licenses
in North Carolina, Massachusetts, and Virginia. Id. at 2. From 1955 to 1964, Dr. Kinsbourne
held a series of postdoctoral positions in pediatrics and neurology in hospitals in England, with
one year of residency in pediatrics at Bellevue Hospital in New York. Id. at 1. His clinical
experience includes a stint as a senior staff physician in the Hospital for Sick Children in
Toronto, Ontario from 1974 to 1980, and as a clinical associate in neurology at Massachusetts
General Hospital from 1981 to 1991. Id. at 2-3. Dr. Kinsbourne has also held a series of
academic positions in pediatrics, neurology, and psychology in various universities throughout
his years of practice. Id. at 2-3. Despite Dr. Kinsbourne’s exceptional credentials, other cases in
the Vaccine Program have noted that it has been many years since Dr. Kinsbourne has regularly
seen patients. See, e.g., McCullom v. Sec’y of Health & Human Servs., No.14-790V, 2017 WL
5386613, at *6 (Fed. Cl. Spec. Mstr. Sept. 15, 2017) (citing Pope v. Sec’y of Health & Human
Servs., No. 14-078V, 2017 WL 2460503, at *8 (Fed. Cl. Spec. Mstr. May 1, 2017)). Dr.
Kinsbourne is qualified to speak as an expert in neurology, although he does not have any
specific expertise in narcolepsy besides his previous work in the Vaccine Program. See

                                                11
generally id. Dr. Kinsbourne submitted one expert report and two supplemental reports in this
case. Pet’r’s Exs. 12, 16, 53.

        In his first report, Dr. Kinsbourne proposed that Petitioner developed narcolepsy as a
result of an autoimmune reaction to the flu vaccine Petitioner received on November 7, 2012.
Pet’r’s Ex. 12 at 7-8. Dr. Kinsbourne placed the onset of Petitioner’s condition in early
December of 2012, “less than four weeks” after her vaccination. Id. at 3. Dr. Kinsbourne
explained that narcolepsy is a condition marked by a “deficient ability to maintain vigilan[t]
states.” Id. at 4. He wrote that narcoleptics “have daily periods of abnormal sleepiness, even
when fully engaged in activities,” and “the need to sleep is overwhelming and insurmountable.”
Id. Dr. Kinsbourne explained that, in normal sleep patterns, REM sleep begins “some one-and-a-
half hours” after an individual falls asleep. Id. In narcoleptics, Dr. Kinsbourne continued, REM
sleep can begin “within less than five minutes of sleep onset.” Id.

       Dr. Kinsbourne noted Petitioner’s case also included a diagnosis of narcolepsy with
cataplexy. Id. Cataplexy, Dr. Kinsbourne explained, “refers to the sudden onset of weakness of
postural muscle tone, usually brought on by strong emotions, notably when expressed in laughter
or anger.” Id. These episodes are marked by a person’s head dropping or a complete collapse
“during which individuals are unable to move, speak, or keep their eyes open.” Id. Dr.
Kinsbourne wrote these periods “may last no longer than 30 seconds or up to 10 minutes.” Id.
Cataplectic episodes are differentiated from most seizure disorders, Dr. Kinsbourne wrote,
because the individual suffering from a cataplectic attack remains fully conscious for the
duration of the episode. Id.

         Dr. Kinsbourne explained that the clinical diagnosis of narcolepsy can be verified by
polysomnography or by “finding a low or undetectable level of neuropeptide [h]ypocretin in the
cerebrospinal fluid.” Id. Dr. Kinsbourne cited the criteria for narcolepsy with cataplexy as put
forward by the International Classification of Sleep Disorders to confirm Petitioner’s diagnosis.
Id. at 4-5. Petitioner meets two diagnostic criteria for narcolepsy, Dr. Kinsbourne explained: 1)
“The patient has daily periods of irrepressible needs to sleep or daytime lapses into sleep,
occurring for at least 3 months, [and] 2) The presence of one or both of the following: cataplexy
and a mean sleep latency of at most [eight] minutes and [two] or more sleep onset REM periods .
. . or an MSLT (multiple sleep latency test) performed according to standard techniques.”15 Id. at
4-5.

        Dr. Kinsbourne wrote that narcolepsy has a natural prevalence of two-five cases in
100,000 people. Id. at 5. However, Dr. Kinsbourne highlighted that several epidemiological
studies show a “significant increase” in narcolepsy cases following both the 2009 H1N1 winter
flu pandemic in China and the widespread administration of the pandemic H1N1 flu vaccine
Pandemrix throughout Europe from 2008 to 2010. Id. at 5. An article published by Han et al.,
found it to be a “[three]-fold increase in narcolepsy onset following the 2009 . . . pandemic.”

15
  Dr. Kinsbourne did not attest that Petitioner meets the second diagnostic criteria, as it requires
a measurement of the subject’s hypocretin-1 concentration in the spinal fluid, a test which is no
longer done for diagnostic purposes in the United States. See Pet’r’s Ex. 12 at 5; see also Tr.
270-71.

                                                 12
Pet’r’s Ex. 24 at 1; Fang Han et al., Narcolepsy Onset is Seasons and Increased following the
2009 H1N1 Pandemic in China, 70 Annals Neurology 410, 410 (2011). Dr. Kinsbourne also
discussed a study done in Sweden that found “within three months of Pandemrix vaccination, the
incidence of new onset narcolepsy was 14.1/100,000, as compared to 1.3/100,000 [with no
vaccination].” Pet’r’s Ex. 12 at 5. Although Dr. Kinsbourne used these studies to support his
theory relating Fluzone to narcolepsy, he conceded that “[t]here is no published formal
epidemiological study of association of H1N1 vaccines and narcolepsy in the U.S.” Id. at 6. Dr.
Kinsbourne also discussed the Duffy study and characterized it as an “ecological study” that
represented a “retrospective review of electronic healthcare databases of nine health maintenance
organizations in the Vaccine Safety Link.” Id. Dr. Kinsbourne found that “[t]he outcome of the
safety review by Duffy et al. (2014) was not definitive.” Id.

        As for the mechanism behind narcolepsy, Dr. Kinsbourne explained that narcoleptics are
deficient in the neuropeptide hypocretin (also known as orexin), which controls wakefulness. Id.
at 6-7. He stated that hypocretin-secreting neurons project from the hypothalamus throughout
the central nervous system “to neurons involved in the regulation of feeding, sleep-wakefulness,
neuroendocrine homeostasis and autonomic regulation.” Id. (citing Josh Mahlios et al., The
Autoimmune Basis of Narcolepsy, 23 Current Op. Neurobiology 767, 767 (2013)). The
excitatory action of hypocretin is counter-balanced, Dr. Kinsbourne continued, by other
neurotransmitters released by the hypothalamus, GABA and galanin. Id. at 6-7. Thus, “[w]ake-
promoting and sleep-promoting loci in separate regions of the hypothalamus inhibit each other”
and the “inactivation of either system leaves the other in relative control, resulting either in
insomnia or in narcolepsy.” Id. at 6-7.

        After describing what occurs when an individual suffers from narcolepsy, Dr. Kinsbourne
opined that the loss of hypocretin in narcolepsy “appears to be a consequence of a destructive
autoimmune attack.” Id. at 7. Dr. Kinsbourne asserted that this autoimmune reaction is caused
by the immune system’s CD4+ T cells attacking hypocretin molecules. Id. He stated that there
is a “double- or two-hit mechanism at work” that creates T cells that target hypocretin. Id. The
first mechanism is a genetic susceptibility found in “almost all” narcoleptic patients with low
hypocretin. Id. In this population, researchers found a specific, genetic immune system marker,
the Human Leucocyte Antigen (“HLA”) DR2/DQW1.16 Id. The second mechanism that Dr.
Kinsbourne described is “the provocative infection or vaccination that transforms [genetic
susceptibility] into the clinical reality of a case of narcolepsy.” Id. This infection or vaccination,
Dr. Kinsbourne explained, causes HLA molecules to present antigens that cause T cells to
recognize hypocretin as an “invader.” Id.

        Dr. Kinsbourne cited to an article by De La Herrán-Arita et al., for the proposition that
the immune system targets hypocretin due to “molecular mimicry between epitopes of
[h]ypocretin and the influenza hemagglutinin surface protein.” Id. (citing to Alberto K. De la
Herrán-Arita et al., CD4+ T Cell Autoimmunity to Hypocretin/Orexin and Cross-Reactivity to a
2009 H1N1 Influenza A Epitope in Narcolepsy, 5 Sci. Translational Med. 1 (2013) [hereinafter
referred to as “De La Herrán-Arita”]). De La Herrán-Arita “reported the presence of CD4+ T
cells that are reactive to [h]ypocretin in patients with narcolepsy.” Id. at 8. Dr. Kinsbourne

16
     HLA alleles “present antigens to T cells.” Pet’r’s Ex. 12 at 7.

                                                   13
conceded that the exact component of the hypocretin neurons that cross-reacts with the influenza
virus is unknown, and that “cross-reactivity between the hemagglutinin moiety of the H1N1
influenza . . . and a component peptide of the [h]ypocretin molecule has been suggested but not
yet been conclusively demonstrated.” Id.

        Finally, Dr. Kinsbourne addressed several studies that contemplate whether the adjuvant
present in the Pandemrix vaccine is the cause of some patients developing narcolepsy. Id. at 8.
Dr. Kinsbourne argued that the AS03 adjuvant found in Pandemrix “maximizes existing
population of CD4+ T cells,” which then causes an enhanced immune reaction that “stimulates
the production of hypocretin-specific CD4+ cells.” Id. In this way, Dr. Kinsbourne argued, the
adjuvants do not cause the autoimmune reaction by way of molecular mimicry, but instead
enhances it. Id. Indeed, Dr. Kinsbourne wrote, “[t]his may explain why the incidence of post-
vaccination onset of narcolepsy is more easily demonstrated in populations exposed to this
variant of the H1N1 vaccine.” Id. Dr. Kinsbourne concluded that the H1N1 virus itself triggers
the autoimmune response that causes narcolepsy, rather than the vaccine’s adjuvant. Id. He
concedes that adjuvanted influenza vaccines have never been administered in the United States,
and Petitioner did not receive an adjuvanted flu vaccine. Id.

                   b. Respondent’s Expert, Dr. Thomas Scammell

        Dr. Thomas Scammell submitted one expert report in this case. Resp’t’s Ex. A. Dr.
Scammell is currently a Professor of Neurology at Beth Israel Deaconess Medical Center, Boston
Children’s Hospital, and Harvard Medical School. Id. at 1. He is board-certified in neurology,
psychiatry, and sleep medicine. Id. For the last twenty years, he has practiced as a neurologist, a
clinical and basic researcher in sleep medicine, and a lecturer on narcolepsy and the
neurobiology of sleep and wakefulness. Id. He was a member of the International Classification
of Sleep Disorders, and in that role, “helped develop the current consensus definitions of
narcolepsy.” Id. at 1-2. Dr. Scammell has also authored “over [one hundred] publications,
mostly focused on narcolepsy and sleep disorders,” and currently cares “for about [sixty] patients
with narcolepsy.” Id. at 1. Dr. Scammell estimates that he has treated over one hundred patients
with narcolepsy over the course of his career. Id.

        Dr. Scammell primarily raised concerns in his expert report regarding Petitioner’s
diagnosis. Id. at 5. Dr. Scammell also disputed Dr. Kinsbourne’s contention that the Fluzone
vaccine caused Petitioner’s narcolepsy and argued that neither the medical literature, nor the
clinical record, support Dr. Kinsbourne’s argument. Id.

       First, Dr. Scammell wrote that “[he] is not convinced” of Petitioner’s diagnosis of
narcolepsy with cataplexy. Id. Dr. Scammell explained that “one must consider” Petitioner’s
symptoms of cataplexy in order to determine whether Petitioner has narcolepsy type one
(“NT1”) or narcolepsy type two (“NT2”). Id. at 5. NT1 is defined as “symptoms of chronic
sleepiness plus cataplexy, with a MSLT showing a sleep latency less than [eight] minutes and
REM sleep in [two] or more of the daytime naps.” Id. Alternatively, Dr. Scammell noted, “NT1
can be diagnosed by the combination of chronic sleepiness and low levels of hypocretin-1 in
cerebrospinal fluid.” Id.

                                                14
        Cataplexy, Dr. Scammell explained, consists of “brief periods of partial or complete
muscle weakness, almost always triggered by strong, usually positive emotions.” Id. Dr.
Scammell described a typical cataplectic episode as the patient’s speech becoming slurred,
eyelids closing, and the head lolling forward. Id. In a severe attack, “the patient may develop
widespread weakness, causing them to collapse to the ground.” Id. Dr. Scammell wrote that a
person suffering such an attack may be “unable to move for [one to two] minutes.” Id. Dr.
Scammell opined that Petitioner’s episodes are “atypical” in both duration and character. Id. at
6.

        Dr. Scammell indicated that Petitioner’s self-described cataplectic episodes lasted up to
twenty minutes, which is much longer than the typical cataplectic attack that lasts one-two
minutes. Id. Additionally, Dr. Scammell explained that cataplexy is “almost always triggered by
strong emotions;” however, the written record does not mention “any clear emotional triggers”
for Petitioner. Id. Petitioner also stated that she stares during her episodes. Id. Dr. Scammell
noted that staring is “quite unusual” for cataplexy, as an individual’s eyes “are generally closed
due to facial weakness.” Id. Dr. Scammell commented on Petitioner’s husband’s testimony that
someone always must be by Petitioner’s side “to ensure her safety.” Id. Dr. Scammell explained
that throughout his practice treating narcolepsy, he has never “encountered this degree of
dependence due simply to narcolepsy.” Id. Dr. Scammell wrote that Petitioner’s description of
being tired and crying after an episode is also highly unusual, as in most cases “people usually
regain full muscle power and resume their activities . . . .” Id. Dr. Scammell opined that
Petitioner’s episodes could be “pseudo-cataplexy[,] episodes of subjective weakness related to
psychological factors.” Id. Notwithstanding Dr. Scammell’s written analysis contrasting
Petitioner’s symptoms with a more common manifestation of narcolepsy with cataplexy,
ultimately the expert hesitated to confirm or reject her diagnosis without speaking with or
examining Petitioner himself. Id.

         If Petitioner does not have cataplexy, Dr. Scammell wrote, “one must consider the
possibility of NT2.” Id. at 7. NT2, Dr. Scammell explained, “is defined as chronic sleepiness
with a MSLT showing a sleep latency less than [eight] minutes and REM sleep in [two] or more
of the daytime naps.” Id. A diagnosis of NT2 relies “strongly on the MSLT,” but as Dr.
Scammell explained, there is evidence in the medical record that Petitioner’s MSLT was not
performed per American Academy of Sleep Medicine guidelines. Id. These guidelines mandate
that patients must be off “relevant psychoactive medications, . . . and concomitant sleep disorders
. . . [and] must first be treated to minimize external factors that could produce a false-positive
MSLT.” Id. According to Petitioner’s medical records, she was taking Lexapro, Topamax, and
lorazepam during her MSLT performed on September 14, 2013. Id. Dr. Scammell explained
that these medications are sedating and can affect REM sleep. Id. Dr. Scammell continued that
Petitioner also had other medical issues that can cause sleepiness, including sleep apnea and
depression. Id. In support that Petitioner’s sleepiness may not be solely caused by narcolepsy,
Dr. Scammell emphasized that Petitioner’s sleepiness improved with the use of a CPAP machine
that was prescribed for her sleep apnea. Id. Dr. Scammell further noted that Petitioner once
“spent two weeks in bed,” and such a lengthy stay in bed “is more consistent with depression.”
Id. at 8.

                                                15
         Dr. Scammell observed that “[s]ome other [of Petitioner’s] clinical features are consistent
with narcolepsy but not of much help diagnostically.” Id. These include Petitioner’s positive
test for the narcolepsy genetic marker, HLA DQB1*06:02. Id. Dr. Scammell cautioned that
although the gene is found in 90% of patients with NT1 and about 50% of patients with NT2, “it
is also found in 12-25% of the general population . . . .” Id. This occurrence in the general
population, Dr. Scammell wrote, makes a positive test “of little diagnostic usefulness.” Id.

        Dr. Scammell then addressed Dr. Kinsbourne’s opinion that Petitioner’s narcolepsy was
caused by her Fluzone vaccination. Id. at 9. Dr. Scammell agreed with Dr. Kinsbourne that
there was an associated increase in narcolepsy cases following the use of the Pandemrix
vaccination. Id. However, Dr. Scammell emphasized, “the great majority of patients who
developed narcolepsy were under the age of [twenty] years, the increased risk in adults was only
[two to four] fold, and even with this vaccine, there was no increase in narcolepsy among adults
over age [forty].” Id. In addition, the increased rate of narcolepsy was associated with
Pandemrix, but not the two other flu vaccines used in the same year, Arepanrix and Focetria. Id.
Dr. Scammell concluded that the increased rate with respect to Pandemrix is a result of “brand-
specific differences in vaccine production.” Id.

        Dr. Scammell highlighted that the increase in new cases of narcolepsy was limited to the
2009-2010 flu season, and noted there were “no reports of narcolepsy associated with influenza
vaccine in subsequent years.” Id. at 10. Indeed, Dr. Scammell wrote that “[m]oderate evidence
suggests that . . . infection with H1N1 influenza (not vaccination) was associated with an
increase in new cases of narcolepsy in China” in the winter of 2009-2010, but “narcolepsy rates
then returned to typical levels in subsequent years.” Id. This “return to baseline” suggested to
Dr. Scammell that “some factor specific to 2009-2010 H1N1 strain contributed to the
development of narcolepsy.” Id. Thus, for Dr. Scammell, the Fluzone vaccination Petitioner
received for the 2012-2013 flu season, “should not trigger the development of narcolepsy.” Id.
Dr. Scammell then emphasized that Pandemrix was never used in the United States, and “there is
no evidence that influenza vaccines used in the U.S. were associated with narcolepsy.” Id.

        Finally, Dr. Scammel emphasized that “[t]here is no direct evidence for a mechanism of
molecular mimicry.” Id. He noted Petitioner’s expert discussed the De la Herrán-Arita article
that suggests an autoimmune response could “harm the hypocretin neurons through a mechanism
of molecular mimicry.” Id. at 11. Dr. Scammell then immediately pointed out that Dr.
Kinsbourne “failed to mention that the findings were retracted soon after publication.” Id. As
further evidence against vaccine causation, Dr. Scammell applied De la Herrán-Arita’s finding to
Petitioner and noted that “[e]ven with Pandemrix, there was no increase in narcolepsy among
adults over age [forty].” Id. Therefore, “even if [Petitioner] had received Pandemrix,” she was
forty-four at the time of her vaccination and “her risk of developing narcolepsy would not be
increased.” Id. Dr. Scammell did concede that the interval between vaccination and onset of her
condition “seems reasonable” given the onset of narcolepsy in European patients after Pandemrix
vaccination. Id. Dr. Scammell concluded that, assuming Petitioner has narcolepsy, “the simplest
explanation” was that her condition was caused by “factors other than Fluzone,” such as a
“common infection.” Id.

                   c. Respondent’s Expert, Dr. Andrew MacGinnitie

         Dr. Andrew MacGinnitie submitted a total of three expert reports in this case.
Respondent filed Dr. MacGinnitie’s first report on February 8, 2017. Resp’t’s Ex. C. Dr.
MacGinnitie is an attending physician and the Clinical Director for the Division of Immunology
at Boston Children’s Hospital, and a Professor of Pediatrics at Harvard Medical School. Id. at 1.
Dr. MacGinnitie graduated from the University of Chicago Pritzker School of Medicine with an
M.D. and a Ph.D. from the Department of Pathology. Id. Dr. MacGinnitie then completed a
residency in pediatrics “primarily” at Boston Children’s Hospital and Boston Medical Center.
Id. at 1-2. He is board-certified in both allergy/immunology and pediatrics, and has been
practicing as an allergist/immunologist for fifteen years. Id. at 2. He states that he sees “more
than 1,500 patients annually” for a “variety of immunologic diseases[,] including reactions to
vaccines.” Id. He has provided expert testimony in the Vaccine Program since 2015 and wrote
that this is the sixth case in which he has opined. Id.

       Dr. MacGinnitie focused on Dr. Kinsbourne’s argument that Petitioner’s Fluzone vaccine
caused her narcolepsy with cataplexy and asserted three main points in rebuttal. Id. at 3. First,
he argued that there is no evidence linking seasonal influenza vaccinations to narcolepsy, and the
2009 increase in post-vaccination narcolepsy patients was most likely caused by the adjuvant
present in that specific vaccine. Id. at 1. Second, Dr. MacGinnitie posited that there is strong
epidemiological evidence showing “no increased risk with seasonal vaccination,” and finally, he
noted that Dr. Kinsbourne’s theory of causation “relies primarily on an article that has been
retracted and is therefore not reliable.” Id. (emphasis in original).

         Dr. MacGinnitie first explained that “all references cited by Dr. Kinsbourne [to show a
connection between an influenza vaccination and narcolepsy] report on an association between
adjuvanted influenza vaccines and narcolepsy.” Id. at 8. An adjuvant, Dr. MacGinnitie
continued, is a substance added to a vaccine in order to amplify the immune response, such as
the “formulation of oil mixed in water” that was added to Pandemrix by the manufacturers. Id.
Dr. MacGinnitie explains that adding an adjuvant can “elicit[] a response [measured by antibody
titers] 3.5 to 10 times greater than non-adjuvanted vaccines.” Id. at 8. Dr. MacGinnitie
emphasized that the Fluzone vaccine received by Petitioner does not contain adjuvants and went
on to state that no seasonal influenza vaccines used in the United States contain adjuvants. Id. at
5, 8. Therefore, the “most logical interpretation of the data on influenza vaccination and
[narcolepsy] is that the increased risk is limited to adjuvanted subunit vaccines such as
Pandemrix . . . . Other vaccines, including non-adjuvanted subunit vaccines such as Fluzone, are
not associated with development of narcolepsy.” Id. at 9.

        In fact, Dr. MacGinnitie wrote, there exists “direct epidemiologic evidence [that]
demonstrates no association between season influenza vaccination and narcolepsy.” Id. at 8. Dr.
MacGinnitie then cited to three studies that show this lack of an association. The first, Lee et al.,
did not find any link between non-adjuvanted pandemic and seasonal flu vaccines and
narcolepsy through a database search containing over four million reports of adverse events. Id.
(citing Resp’t’s Ex. PP; Grace M. Lee et al., H1N1 Seasonal Influenza Vaccine Safety in the
Vaccine Safety Datalink Project, 41 Am. J. Preventative Med. 121 (2011)). Second, Choe et al.,
examined new diagnoses of narcolepsy in South Korea following an epidemic H1N1 vaccination

                                                 17
program wherein both adjuvanted and non-adjuvanted vaccines were used. Id. (citing Resp’t’s
Ex. HH; Young June Choe et al., No Association Between Influenza A(H1N1)pdm09 Vaccination
and Narcolepsy in South Korea: An Ecological Study, 30 Vaccine 7439 (2012)). Dr.
MacGinnitie wrote that the study found no increases in narcolepsy rates, “and rates were actually
higher prior to the vaccination program.” Id. Last, Dr. MacGinnitie cited to the Duffy study to
show that non-adjuvanted influenza vaccines are not associated with an increase in narcolepsy.
Id. In their study, Duffy, “conducted a careful examination of new cases of narcolepsy utilizing
the Vaccine Safety Datalink . . . for patient who received a pandemic H1N1 vaccine in 2009 and
seasonal influenza vaccine during the 2010-2011 season.” Id. Dr. MacGinnitie highlighted that
forty-three percent of the patients who received the vaccine during the 2010-2011 season
received the Fluzone vaccine. Id. Out of an expected rate of 4.35 new cases of narcolepsy
(estimated as the underlying rate of new cases in the population), Duffy found no new cases of
narcolepsy out of more than 439,000 patients. Id. Relatedly, out of “almost 741,000 vaccinated
individuals receiving H1N1-containing seasonal influenza vaccine[s] in 2010-2011 there were
[two] cases of narcolepsy, compared to an expected incidence of more than 7.5 cases.” Id. “In
summary,” Dr. MacGinnitie wrote, “narcolepsy has been associated with adjuvanted influenza
vaccines[,] which are known to produce very strong immune responses, but not with non-
adjuvanted vaccines such as Fluzone.” Id.

        Dr. MacGinnitie concluded by finding that Dr. Kinsbourne’s reliance upon the De la
Herrán-Arita article for a theory of causation is misplaced, as the article was retracted by the
authors. Id. at 1. Dr. Kinsbourne relied upon the De la Herrán-Arita study “as evidence that
individual T cells can recognize both the hemagglutinin of H1N1 influenza and hypocretin.” Id.
at 4. The data produced by De la Herrán-Arita purported to support this hypothesis, but “certain
experiments could not be reproduced and the paper was retracted.” Id. at 6. Dr. MacGinnitie
explained that in fact, copies of the data produced by the study “suggest[] that the paper was
fraudulent a[nd] in several instances[,] duplicate images are shown as coming from different
patients.” Id. Although the official retraction “states that the authors were unable to replicate
key findings,” Dr. MacGinnitie continued, “presenting the same image as from different patients
is fraud and indicates that the findings were almost certainly never accurate.” Id. at 7. Dr.
MacGinnitie does note, however, that the Ahmed study (2015),17 suggests a link between
Pandemrix and development of antibodies between hypocretin receptors, but added the caveat
that the “article is quite limited in numbers and reports that a number of healthy controls also
have such antibodies.” Id.

                  d. Dr. Kinsbourne’s Second Expert Report

        Dr. Kinsbourne’s second report was written largely in response to Dr. Scammell’s report.
Pet’r’s Ex. 16. Dr. Kinsbourne raised three points in response to Dr. Scammell. Id. First, Dr.
Kinsbourne wrote that he relies on Petitioner’s treating physicians for Petitioner’s diagnosis of
narcolepsy with cataplexy and “the timing of its onset.” Id. Second, Dr. Kinsbourne agreed with
Dr. Scammell that narcolepsy was not the only cause of Petitioner’s sleepiness. Id. Dr.

17
  Resp’t’s Ex. LL; Syed Sohail Ahmed et al., Antibodies to Influenza Nucleoprotein Cross-React
with Human Hypocretin Receptor 2, 7 Sci. Translational Med. 1 (2015) [hereinafter referred to
as Ahmed (2015)].

                                               18
Kinsbourne noted that Petitioner also has sleep apnea. Id. Third, Dr. Kinsbourne put forward a
new, “medically-reasonable mechanism by which a non-adjuvanted H1N1 containing vaccine,
and specifically Fluzone, could have caused [Petitioner’s] narcolepsy with cataplexy.” Id.
Although Dr. Kinsbourne did not address Dr. MacGinnitie’s report and more specifically Dr.
MacGinnitie’s observation that the De la Herrán-Arita article was retracted due to fraud, Dr.
Kinsbourne’s new causation theory did not rely upon the De la Herrán-Arita article. Id. Instead,
Dr. Kinsbourne explicated a mechanism by which the nucleoprotein in the influenza vaccine is
the primary agent that causes an autoimmune reaction to induce narcolepsy.

       Dr. Kinsbourne discussed Dr. Scammell’s opinion that Pandemrix is associated with an
increase in narcolepsy cases due to “brand specific differences in vaccine production.” Id. at 1.
These “brand specific” differences, Dr. Kinsbourne argued, include adjuvants and the amount of
influenza nucleoprotein found within the vaccine. Id. at 1-2.

           Dr. Kinsbourne first argued that it is the virus itself, not adjuvants, that causes narcolepsy
following an influenza vaccination. Id. at 2. He posited that adjuvants “potentiate the adaptive
immune response but they do not initiate it.” Id. Dr. Kinsbourne argued that adjuvants “can also
participate in instigating the autoimmune response[,] . . . [but] the higher risk of narcolepsy onset
. . . is related to the viral component of vaccine.” Id. (citing Pet’r’s Ex. 41; Ji Hyun Song et al.,
Narcolepsy: Association with H1N1 Infection and Vaccination, 7 Sleep Med. Res. 43 (2016)).
For Dr. Kinsbourne, the “ability to cause narcolepsy resides in the viral component of the
vaccine, whereas the adjuvant . . . could lead to an increase in the size of the affected
population.” Id. This explanation shows why an adjuvanted vaccine like Pandemrix resulted in
a larger increase in narcolepsy cases compared to the non-adjuvanted vaccines used in the United
States. Id.

        Dr. Kinsbourne argued that the component within the vaccine itself that causes
narcolepsy is influenza nucleoprotein. Id. at 2. Dr. Kinsbourne argued that there is cross-
reactivity between “a comparable peptide in the influenza vaccine and hypocretin receptor 2.”
Id. Dr. Kinsbourne cited to Ahmed (2015) for the proposition that “antibodies from vaccine-
associated narcolepsy sera cross-reacted with both influenza nucleoprotein and hypocretin
receptor 2 [(“HCRTR2”)].” Id.

        Ahmed (2015) surveyed several groups to judge the prevalence of antibodies against
hypocretin receptor-2, primarily comparing groups of individuals vaccinated with Pandemrix and
Focetria, a vaccine similarly adjuvanted to Pandemrix. Pet’r’s Ex. 38 at 1, Ahmed (2015). The
study found that there were increased levels of this antibody in people with narcolepsy after
Pandemrix vaccination, compared to the groups who had been exposed to the wild-type influenza
virus and who had been vaccinated with Focetria. Id. The authors then theorized that this
difference could be explained by the level of influenza nucleoprotein in the different vaccines.
Id.

        Dr. Kinsbourne explained that hypocretin receptors are part of a positive feedback loop,
wherein hypocretin stimulates hypocretin neurons through excitation of hypocretin receptors to
produce more hypocretin. Id. at 3-4. Inactivation of the hypocretin receptors, Dr. Kinsbourne
wrote, “would diminish their output of hypocretin,” leading to “a hallmark dwindling away of

                                                   19
hypocretin levels as observed in cerebrospinal fluid in people with narcolepsy.” Id. at 4. Indeed,
Dr. Kinsbourne continued, studies show that inactivation or damage to hypocretin receptors
result in narcolepsy in animals. Id. at 2 (citing Pet’r’s Ex. 26, Ling Lin et al., The Sleep Disorder
Canine Narcolepsy Is Caused by a Mutation in the Hypocretin (Orexin) Receptor 2 Gene, 98
Cell 365 (1999) (inactivation caused by mutation); Pet’r’s Ex. 43, Jon T. Willie et al., Distinct
Narcolepsy Syndromes in Orexin Receptor-2 and Orexin Null Mice: Molecular Genetic
Dissection of Non-REM and REM Sleep Regulatory Processes, 38 Neuron 715 (2003)
(inactivation caused by genetic manipulation)). One study, Dr. Kinsbourne continued, found that
“the loss of hypocretin function in narcolepsy results from a cytotoxic or immunologically
mediated attack focused on hypocretin receptor 2 or an antigen anatomically linked to hypocretin
receptor 2.” Id. at 3. (citing Pet’r’s Ex. 42, Thomas C. Thannickal et al., Pattern of Hypocretin
(Orexin) Soma and Axon Loss, and Gliosis, in Human Narcolepsy, 13 Brain Pathology 340
(2003)).

       This immunological attack on hypocretin receptors, Dr. Kinsbourne theorized, is caused
by cross-reactivity between influenza nucleoprotein found in the flu vaccine and hypocretin
receptors. Id. at 2. Dr. Kinsbourne cited to Ahmed (2015) to show that “the amount of
nucleoprotein [in brands of H1N1 flu vaccines] correlates with the expected differential
frequency of narcolepsy arising in reaction to the individual vaccines.” Id. at 4. He stated that
Ahmed (2015) found that Fluzone, the vaccine at issue in this case, has “one of the highest
nucleoprotein contents among the available seasonal influenza vaccines, falling short only of the
even higher nucleoprotein contents of Pandemrix . . . .” Id. Dr. Kinsbourne concluded that “a
medically reasonable mechanism for the action of vaccines in causing narcolepsy is necessarily
incomplete;” however, his theory “derives from respected sources and is a sufficient basis for
proposing a mechanism of injury at a level of reasonable medical probability.” Id.

                   e. Dr. MacGinnitie’s Second Report

        Dr. MacGinnitie’s second report primarily disputed the significance of Ahmed (2015),
which Dr. Kinsbourne relied upon to elucidate his theory of causation. Resp’t’s Ex. RR. Dr.
MacGinnitie wrote that Dr. Kinsbourne “has abandoned his original theory that cross-reactivity
between hemagglutinin component of the H1N1 influenza vaccine and neurons producing
hypocretin-1 in the hypothalamus caused [Petitioner’s] narcolepsy.” Id. at 1. Instead, Dr.
MacGinnitie continued, Dr. Kinsbourne “now proposes that [Petitioner’s] illness was caused by
cross-reactivity between a distinct influenza protein, nucleoprotein, and neurons expressing the
receptor for hypocretin,” as proposed by Ahmed (2015). Id.

        Dr. MacGinnitie summarized that Ahmed (2015) found hypocretin receptor antibodies in
seventeen out of twenty patients with narcolepsy after receiving Pandemrix. Resp’t’s Ex. RR at
1. Dr. MacGinnitie then argued that the significance of these antibodies is unclear, as numerous
control groups in the study also had these antibodies. Id. For example, the study found the
antibodies in five out of twenty patients without narcolepsy who had been exposed to wild-type
influenza. Id. In addition, the study found the antibodies in eleven out of twenty historical
control sera, but these control patients did not present with any evidence of narcolepsy. Id.

                                                 20
         Dr. MacGinnitie then presented four issues with the study. Id. First, Dr. MacGinnitie
highlighted the small sample size of the Ahmed (2015) study. Id. He noted that the study was “a
single report on [twenty] patients with post-vaccination narcolepsy and [sixty] poorly matched
controls [that] represents the sum total of published data suggesting” a causal link between
influenza nucleoprotein and manifestation of narcolepsy. Id. at 2. Second, Dr. MacGinnitie
emphasized that “there is [no] good explanation for the fact that cross-reactive hypocretin
receptor/nucleoprotein antibodies are present in a number of patients without narcolepsy.” Id.
“This includes,” Dr. MacGinnitie continued, “greater than 50% of children serving as
historical controls and without narcolepsy . . . .” Id. (emphasis in original). Additionally, the
levels of the antibodies in the control group without narcolepsy, Dr. MacGinnitie wrote, “are not
statistically significantly different from those found in the Pandemrix[-]vaccinated patients with
narcolepsy.” Id. Patients with influenza infections, but not narcolepsy, Dr. MacGinnitie wrote,
also have the antibodies; “[t]his fact casts considerable doubt on the importance of these
antibodies.” Id.

         Third, Dr. MacGinnitie argued that “no evidence is provided that T[]cells specific for the
proposed cross-reactive nucleoprotein exist.” Id. at 3. Dr. MacGinnitie explained that
narcolepsy is “almost exclusively seen in patients who carry the HLA DQB 1*0602 allele.” Id.
at 1. He continued that HLA proteins “present peptides (protein fragments) on the surface of
cells,” and the exclusivity between this allele and narcolepsy “indicates the obligate involvement
of T cells that recognize this HLA type as the pathogenesis of narcolepsy.” Id. However, Dr.
MacGinnitie wrote, “no data is presented that these [T] cells exist.” Id. at 3. In addition, Dr.
MacGinnitie continued, “no evidence is presented that the cross-reactive antibodies cause
narcolepsy.” Id. “Correlation does not imply causation,” Dr. MacGinnitie wrote of the anti-
hypocretin receptor antibodies, “and it is possible that the identified antibodies are as result, not a
cause of narcolepsy.” Id. Fourth, Dr. MacGinnitie wrote that the Ahmed (2015) study “lacks
appropriate controls, particularly antibody data from individuals immunized with Pandemrix but
not developing narcolepsy.” Id. Dr. MacGinnitie quoted the Ahmed (2015) study to emphasize
that “[t]he findings reported in this study should be viewed as a step in understanding the
mechanism of vaccine-associated narcolepsy and will benefit from additional confirmatory
studies.” Id. at 4 (citing Ahmed (2015) at 8). Dr. MacGinnitie concluded his report by citing
again to the Duffy study to show “there is not an association between non-adjuvanted
influenza vaccines, such as the Fluzone that [Petitioner] received, and development of
narcolepsy, regardless of nucleoprotein content.” Id. (emphasis in original).

                   f. Petitioner’s Expert, Dr. S. Stanley Young

        Dr. S. Stanley Young’s expert report was filed by Petitioner after the undersigned granted
Petitioner’s motion to continue the hearing. See Docket Rep. Dr. Young’s expert report was
submitted to address the Duffy study and “provide the Court with a detailed report of the study’s
methods and conclusion.” Order, ECF No. 86. Dr. Young is the CEO of CGStat, LLC, a
consulting firm located in Raleigh, North Carolina.18 Pet’r’s Ex. 50 at 1, ECF No. 89-1. Dr.

18
  Dr. Young’s CV is silent on the work his company undertakes. See Pet’r’s Ex. 50 at 1. His
CV also does not specify the specialty in which Dr. Young received his degrees, although he
presumably studied statistics based upon his academic and professional career. Id.

                                                  21
Young received his BS, MES, and Ph.D. from North Carolina State University in 1966, 1968,
and 1974, respectively. Id. Dr. Young is also an Adjunct Professor of Statistics and Biostatistics
and has published a book and numerous academic papers on these subjects. Id. at 1-7.

       Dr. Young first presented a summary of Petitioner’s causation theory based upon the
Ahmed article. Pet’r’s Ex. 52 at 1, ECF No. 89-3. Dr. Young then wrote that Duffy presents
“two important claims.” Id. First, Dr. Young wrote, Duffy asserts that “the vaccine by itself will
not cause narcolepsy,” and second, “ASO3 [the adjuvant in Pandemrix] is not the causative
agent.” Id. (emphasis in original). Dr. Young argued that Ahmed (2015) correctly identified
nucleoprotein as the causative agent Duffy was looking for. Id. at 5-6. Dr. Young cited to the
Ahmed article to show that there was “a lower association” between new narcolepsy cases
following vaccination with Arepanrix in Canada, even though it shares the same adjuvant,
ASO3, with Pandemrix. Id. at 3. Instead, Dr. Young wrote, “[t]here is very good evidence that
the causative agent is high levels of antibodies to NP [, and] [t]here was no way for Duffy in
2014 to know about the future Ahmed hypothesis.” Id. at 6 (emphasis in original).

        In terms of the study itself, Dr. Young commented that the “Duffy study is sensible in
terms of data set and analysis.” Id. at 6. The Duffy study, Dr. Young observed, found a higher
incidence of narcolepsy in people age nineteen or younger in Europe, although in the United
States it tends older, aged twenty or above. Id. Dr. Young concluded that the Duffy study
suggested “that it is not the H1N1 vaccine itself or ASO3 adjuvant (a false lead) which causes
narcolepsy.” Id. Dr. Young asked, “What, then, is the causative agent?” Id. Dr. Young
answered, “The Ahmed hypothesis, antibodies to the nuclear protein [sic], is the current last man
standing.” Id.

                   g. Dr. Kinsbourne’s Third Report

         Dr. Kinsbourne’s third report was also submitted along with Dr. Young’s to address the
Duffy study. See Docket Rep. Dr. Kinsbourne began his report by reiterating the argument he
presented previously, specifically that “the adjuvant does not by itself cause narcolepsy but that
it expands the number of affected individuals when it is combined with a vaccine that can cause
narcolepsy.” Pet’r’s Ex. 53 at 1. This fact, Dr. Kinsbourne wrote, explains how the H1N1
vaccine used in the United States “would be expected to cause far fewer cases of narcolepsy” due
to its lack of adjuvants. Id.

        Dr. Kinsbourne then explained the Duffy study in depth. Id. In Duffy, Dr. Kinsbourne
wrote, “[t]he investigators identified [sixteen] narcoleptics within the chosen six-month period of
interest . . . following H1N1 vaccine (pandemic or seasonal).” Id. In lieu of a control group, Dr.
Kinsbourne wrote, Duffy “compared the number of narcoleptics they identified with an
estimated expected number of cases of narcolepsy which they derived from Silber et al.” Id.
(citing Pet’r’s Ex. 53B, Michael H. Silber et al., The Epidemiology of Narcolepsy in Olmsted
County, Minnesota: A Population-Based Study, 25 Sleep 197 (2002)). The Silber study, Dr.
Kinsbourne continued, “found an incidence rate of narcolepsy of 1.37 per 100,000 (1.05 for
women).” Id. Dr. Kinsbourne also cited to “[t]he only other study of whether H1N1
vaccinations impact the incidence of narcolepsy[,]” Montplaisir et al. Id. (citing Pet’r’s Ex. 33,
Jacques Montplaisir et al., Risk of Narcolepsy Associated with Inactivated Adjuvanted (ASO3)

                                                22
A/H1N1 (2009) Pandemic Influenza Vaccine in Quebec, 9 PLoS ONE 1 (2014)). This study,
performed in Canada, found an “excess risk of narcolepsy of approximately one case per million
vaccine doses” of Arepanrix. Id. Duffy “uncovered six patients with narcolepsy and cataplexy .
. . within the study period,” with only one patient showing “onset of narcolepsy within six
months of an H1N1 vaccination.” Id. In total, Duffy found one patient with narcolepsy and
cataplexy out of “some one-and-one-half-million subjects.” Id. at 2. Dr. Kinsbourne conceded
that Duffy’s data are consistent “with the Montplaisir estimate of one additional case per million
vaccine doses.” Id.

        Dr. Kinsbourne argued “there would be a serious limitation to applying the results of the
Duffy study to the case of [Petitioner].” Id. The primary impediment, Dr. Kinsbourne noted, is
that the Duffy study did not even consider the incidence of narcolepsy in someone Petitioner’s
age. Id. Duffy limited their study to subjects below the age of thirty, whereas Petitioner was
forty-four years old when she developed narcolepsy. Id. According to Silber, “[t]he incidence
rate [of narcolepsy] was highest in the second decade, followed in descending order by the third,
fourth, and first decade,” with zero in the fifth decade of life (age 40-49). Id. Consequently, in
the study used a baseline for Duffy, the incidence of narcolepsy in Petitioner’s age range is zero.
Id. This is because “physicians tend not to consider narcolepsy in the differential diagnosis of
sleep disorders in older adults.” Id. Duffy’s data, Dr. Kinsbourne noted, is therefore inapposite,
as “an appropriate expected value for [Petitioner], aged [forty-four] years, in a Duffy-type study
would be zero, rather than the expected rate that the investigators based on [the Silber study’s]
data for much younger people.” Id. “As is frequently the case with rare event[s],” Dr.
Kinsbourne concluded, “decisions as to causation in [Petitioner’s] case cannot be based on the
outcomes of epidemiological research.” Id.

                   h. Dr. MacGinnitie’s Third Report

      Dr. MacGinnitie’s third expert report addresses both the reports of Dr. Kinsbourne and
Dr. Young, specifically their use of the Ahmed and Duffy studies. Resp’t’s Ex. WW.

        With respect to the Ahmed study, Dr. MacGinnitie wrote that “[t]here is no data linking
the anti-hypocretin receptor antibodies observed in Ahmed . . . to the destruction of hypocretin-
producing neurons.” Id. at 1. Dr. MacGinnitie cited to a comment on Ahmed (2015) that the
mechanism by which the anti-hypocretin receptor antibodies actually cause narcolepsy is “a
major unanswered question . . . .” Id. (citing Anne Vassalli, Sha Li, & Mehdi Tafti, Comment on
“Antibodies to Influenza Nucleoprotein Cross-React with Human Hypocretin Receptor 2,” 7 Sci.
Translational Med. 314 (2015)). Dr. MacGinnitie agreed with Vassalli et al., that “the
hypothesis advanced by Ahmed (that the antibodies cross the blood-brain barrier and destroy
cells expressing this receptor) is ‘unlikely,’ as ‘[hypocretin receptors] [are] expressed in
numerous brain cell types, including some with critical functions.’” Id. And, Dr. MacGinnitie
continued, “[t]here is no evidence that these antibodies are harmful or perform any of the
functions attributed to them by Dr. Young or Ahmed 2015.” Id. Dr. MacGinnitie wrote “[t]he
fact that the rate of narcolepsy varied among different adjuvanted vaccines does not prove the
adjuvant is not responsible.” Id. Instead, Dr. MacGinnitie argued, “[w]hile this data may
indicate adjuvant is not sufficient by itself to cause narcolepsy, it does not change the fact that
adjuvant is required.” Id. (emphasis in original).

                                                23
         “Duffy,” Dr. MacGinnitie wrote, “remains convincing evidence against a relationship
between non-adjuvanted H1N1 vaccine and narcolepsy . . . .” Id. at 2. Dr. MacGinnitie
addressed Dr. Young’s argument that the Duffy authors were unaware of the possible causation
mechanism asserted in Ahmed (2015). Id. Dr. MacGinnitie wrote that “it is irrelevant if the
authors [of Duffy] were aware” of the Ahmed (2015) hypothesis, because Duffy “undertook their
study to determine” whether there was any association between non-adjuvanted flu vaccines and
narcolepsy. Id. Dr. MacGinnitie reasoned that the knowledge of any specific mechanism would
not have affected the statistical findings and “Ahmed et al. simply propose[d] one mechanism by
which non-adjuvanted vaccines could be associated with narcolepsy.” Id. Dr. MacGinnitie also
concluded that “Dr. Kinsbourne is mistaken when he asserts that” Duffy did not have a control
group. Id. Duffy, Dr. MacGinnitie explained, “used as a control group patients who developed
narcolepsy before the H1N1 pandemic started” and compared the rate found therein with the data
from Silber et al. Id. Duffy, Dr. MacGinnitie continued, further “consider[ed] the fact that this
baseline rate [found in Silber] could be wrong, but still would not change their analysis,” as “‘the
zero cases [Duffy] observed in [their] 2009 pandemic vaccinated cohort would still be less than
the 0.652 cases expected.’” Id. Dr. MacGinnitie then highlighted that the Montplaisir study
relied upon by Dr. Kinsbourne concerned an adjuvanted vaccine, and Dr. MacGinnitie dismissed
Dr. Kinsbourne’s argument concerning the age restriction found in Duffy. Id. Dr. MacGinnitie
wrote that “it is true that Duffy was restricted to patients under [thirty] years of age,” but found
“this is reasonable given the increased incidence in younger patients.” Id. “In fact,” Dr.
MacGinnitie continued, “[Duffy] did not observe a single patient in the 20-29 age group who
developed narcolepsy within 180 days of vaccination.” Id.

       Dr. MacGinnitie concluded that “little if any new information is added by” the
supplemental reports of Dr. Young and Dr. Kinsbourne. Id. The Ahmed hypothesis is
“speculative,” and “Duffy remains strong evidence against a relation between non-adjuvanted
vaccination and narcolepsy.” Id.

                                                24
                   a. Fact Testimony

                           i. Petitioner’s Mother-in-Law

        Ms. Walters first met Petitioner in 2008 when Petitioner and Ms. Walters’ son began
dating. Tr. 14-15. Ms. Walters lived with Petitioner and Mr. Dougherty from 2012 to 2016. Id.
at 15. Ms. Walters testified that prior to receiving the flu vaccine Petitioner was “very active”
and “very involved” with her family. Id. at 16. Ms. Walters stated that Petitioner traveled for
her job as a regional manager with Frito-Lay and visited cities across central Indiana while
working up to sixty hours per week. Id. at 16-18. Additionally, Petitioner was active in her free
time, enjoying boating, swimming, and fishing. Id. at 19.

        Ms. Walters testified that she was “fairly certain” Petitioner’s behavior began to change
around September of 2013, approximately ten months after her Fluzone vaccination. Id. at 19-
20. At that time, Petitioner’s “episodes of cataplexy” began to have an effect on Petitioner. Id.
at 20. Ms. Walters described Petitioner’s cataplectic attacks as “terrifying.” Id. She stated that
Petitioner “would go down . . . into a state where you couldn’t wake her up.” Id. at 21. Ms.
Walters testified that these attacks would occur once or twice a day. Id. Ms. Walters described
one instance where Petitioner had a cataplectic episode during one Fourth of July cookout at
Petitioner’s house. Id. Ms. Walters testified that Petitioner entered the garage and “went down.”
Id. at 21-22. Ms. Walters explained that she had to call for Petitioner’s son to help Petitioner to
her bed. Id. at 21-22. Ms. Walters could not say “if it’s sadness or joy or what could bring these
incidences on.” Id. at 22. Ms. Walters recounted Petitioner telling her that Petitioner could hear
her family during these attacks, but “it was obvious [during these episodes that Petitioner]
couldn’t move her body.” Id. at 23. Ms. Walters also recalled two more incidents. Id. at 24.
Ms. Walters said that once in March of 2014, Mr. Dougherty had to pick up Petitioner “a half a
mile from our house” because Petitioner “had [gone] off the road . . . and almost hit[] a telephone
pole.” Id. at 24. There was another incident, Ms. Walters continued, where Petitioner’s son Jake
discovered Petitioner in their barn “out of it, in her car and the car door was locked.” Id. at 24.
Ms. Walters said that Petitioner became “a totally different person” after the vaccination;
Petitioner was unable to participate in her favorite outdoor activities or even cook for herself. Id.
at 24-25. Ms. Walters finished her direct testimony by stating how emotionally and financially
difficult it has been “to have to go through this on a daily basis, it’s hard, very hard.” Id. at 25-
26. “Because I see what it’s doing not only to [Petitioner],” Ms. Walters continued, “but to . . .
her family that love her.” Id. at 26.

        Respondent questioned Ms. Walters on the circumstances surrounding Petitioner’s
cataplectic episodes and her daytime sleepiness. Id. at 26-27. Concerning the Fourth of July
incident, Ms. Walters stated that Petitioner’s mood was “very happy . . . . I know she was having
a good time.” Id. at 27. Ms. Walters further testified that Petitioner has an exaggerated mood
when she has a cataplectic attack. Id. at 27-28. Ms. Walters explained that there were occasions
when Petitioner “goes down” during an episode and is down for “at least [ten] minutes[,] . . . if
not longer sometimes.” Id. at 28. Ms. Walters further explained that Petitioner can “just fall
asleep . . . several times a day,” and this sleepiness could affect Petitioner while watching
television or mid-conversation. Id. at 29.

                                                 25
                          ii. Petitioner’s Mother

        Petitioner’s mother described Petitioner as a “strong willed, hard-working person” before
she received the Fluzone vaccination. Id. at 33. Ms. Burdette stated that Petitioner was a district
manager for Frito-Lay prior to her vaccination, and in that role, Petitioner had to drive across
central Indiana to oversee her sales district. Id. at 34-35. Ms. Burdette estimated that it took her
daughter an hour to drive from her house to her “bin” or warehouse for work. Id. at 35-36.

        Ms. Burdette described Petitioner as “[not] exactly herself” beginning “about three or
four months after” Petitioner received her Fluzone vaccination on November 7, 2012. Id. at 36.
Ms. Burdette described one instance where Petitioner and the family were sitting in the living
room and watching television. Id. at 36. Petitioner could not respond to Ms. Burdette’s
questions and began “staring off into space but still looking at the TV with no response.” Id. at
36-38. Ms. Burdette “poked [Petitioner] and talked to her,” but Petitioner did not respond for
“probably about [five] to [ten] minutes.” Id. at 38. When Petitioner came out of her episode, she
“was very, very emotional because she did not know what had happened, and she just started
crying.” Id. These episodes happened “numerous times.” Id. Ms. Burdette said that the first
time Petitioner had an episode was during the Fourth of July picnic also described by Ms.
Walters. Id. at 39. Ms. Burdette said that Petitioner “just dropped to the ground” and had to be
helped to bed by her husband. Id. During these episodes, Ms. Burdette continued, it was like
Petitioner “wasn’t there.” Id. at 40. Ms. Burdette also described several times when Petitioner
called her on the side of the road, “because [Petitioner] just couldn’t go, and she thought she was
going to pass out . . . .” Id. at 41. Ms. Burdette noted that Petitioner would sometimes be on the
side of the road for fifteen to twenty minutes “because she couldn’t drive any further.” Id. Ms.
Burdette testified that Petitioner had to stop driving because of these episodes and eventually had
to stop working. Id. at 42-43.

        Ms. Burdette testified that Petitioner never had any of “these kinds of spells or events”
before her vaccination, and she was a very “independent” and “self-sufficient person” prior to
her illness. Id. at 44. “I would say,” Ms. Burdette stated, “six months after [Petitioner] had that
vaccination she was a totally different person, totally.” Id. Now, Ms. Burdette continued,
Petitioner was almost entirely reliant on other people. Id. at 45.

        During cross-examination, Ms. Burdette explained that she had lived with Petitioner from
2012, when Ms. Burdette’s house burned down, until Petitioner and her family moved to
Minnesota in 2016. Id. at 46-47. Respondent asked if, during that time, Ms. Burdette had seen
her daughter ever “experience episodes that you would describe as sleepiness?” Id. at 47. Ms.
Burdette denied that she could characterize the episodes as “sleepiness.” Id. Instead, Ms.
Burdette said there would be times when Petitioner would be busy with a task; then “she could
not function any further, and she just had to sit down or lay down or whatever.” Id. at 47-48.
Petitioner would then “sit in the recliner for maybe [twenty] [or] [thirty] minutes, and then she
would be fine when she became aware again.” Id. at 48. Ms. Burdette stated that, at the
beginning of Petitioner’s condition, “she would just be sitting up and participating in a
conversation, and she would be gone.” Id. “[Y]ou’d say something to her,” Ms. Burdette
continued, “and she wouldn’t answer you.” Id. at 49. During these episodes, Ms. Burdette
described Petitioner has having a blank, open stare and “looking like she was watching TV but

                                                 26
unaware.” Id. Ms. Burdette was asked what the nature of the conversation was like when
Petitioner became unresponsive while watching television. Id. at 50. She stated that she did not
“think that made any difference.” Id. at 50-51. “There wasn’t any anxiety or anything going
on,” Ms. Burdette noted. Id. at 51.

          Ms. Burdette recalled an instance when Petitioner fell off a toilet and hit the wall
opposite. Id. at 52. Ms. Burdette explained that Petitioner’s husband heard a “big thump,” and
found Petitioner on the floor in the bathroom. Id. Ms. Burdette described a three- to four-inch
diameter hole from Petitioner’s head making contact with the wall.20 Id. Ms. Burdette then
recalled that immediately prior to Petitioner’s cataplectic events, Petitioner would seem to
experience “extreme excitement, or high anxiety, or sadness.” Id. at 54. Ms. Burdette described
one incident where a box of Petitioner’s father’s football memorabilia “caused her to have an
emotional moment,” but Ms. Burdette “[did not] know if something like that would bring it on or
not . . . .” Id. at 54-55. When asked about how quickly an episode would occur after Petitioner
became emotional, Ms. Burdette answered that Petitioner “was more emotional after the incident
than she was prior to the incident . . . .” Id. at 55.

                            iii. Petitioner’s Son

        Petitioner’s son has been living with his mother since she moved to Minnesota in 2016.
Id. at 58-59. Mr. Ritchey stated that he saw his mother weekly prior to her Fluzone vaccination,
and lived with her on the day of her vaccination, November 7, 2012. Id. at 59. He described his
mother as outgoing and hard-working, and stated that she “worked three times harder than she
should have” to provide the best for her son. Id. After her vaccination, Mr. Ritchey said that “it
started slow,” but she would “space[] out in a blank stare . . . [;] when she finally [comes to], she
[says], I heard you. I was trapped.” Id. at 60-61. Mr. Ritchey described his mother’s spells as
“the creepiest thing I’ve ever seen my mom do in my life,” and very frightening. Id. at 61.

        Mr. Ritchey first saw his mother have one of these attacks one day when she pulled into
the barn after work. Id. Mr. Ritchey stated that his mother fell asleep in her vehicle, but Mr.
Ritchey could not help her because “all [of] the windows [and] doors were locked . . . .” Id. Mr.
Ritchey “thought [his] mom had an accident, like a heart attack . . . . It was a very scary
experience.” Id. He stated that when his mother came to, “she didn’t know what happened.” Id.
at 62. Mr. Ritchey recalled that his mother “just remembered pulling into the . . . barn and [she
was] out.” Id. Mr. Ritchey testified that Petitioner was out for “a good [ten], [twelve] minutes.”
Id. Mr. Ritchey said that he has seen “many” of these attacks. Id. at 63. When Petitioner takes
“medicine so she falls asleep at night,” Mr. Ritchey has “had to move her so she could get her
breathing machine on . . . .” Id. Mr. Ritchey testified that his mother “felt like a dead corpse
because she couldn’t wake up because of how that medicine puts her to sleep now.” Id.
Petitioner has also, Mr. Ritchey continued, “fall[en] asleep in [Mr. Ritchey’s] chair and just . . .
stare[d] at things.” Id. He noted that “she does that a lot.” Id. During these episodes,
Petitioner’s eyes would be open, and “[i]t’s scary.” Id. at 64. It has been difficult for Mr.
Ritchey to see his mother become so incapacitated; “[i]t’s heartbreaking,” Mr. Ritchey said. Id.

20
     Petitioner filed photographs of the damage to the wall. Pet’r’s Exs. 46, 47, ECF Nos. 77-1, 77-
2.

                                                    27
        Mr. Ritchey testified that these episodes occur “if something emotional comes up.” Id. at
65. These episodes occur “once a day[,] [m]aybe more,” Mr. Ritchey said. Id. Mr. Ritchey
recalled the incident where Petitioner fell off of the toilet, damaging the wall. Id. at 66. He
remembered that he was asleep in his bed when he heard “a large boom.” Id. He then ran into
his mother’s room, where Petitioner’s husband was tending to her. Id. Mr. Ritchey testified that
his mother was “in a mixed state” after the fall. Id. Mr. Ritchey also recalled how Petitioner
would enter into these staring episodes while Mr. Ritchey drove her from Minnesota to Indiana.
Id. Mr. Ritchey could not remember if any specific events precipitated these staring spells. Id.
at 66-67. Mr. Ritchey also stated that his mother has some “bad days,” where she is not “able to
function.” Id. at 68.

        On cross-examination, Mr. Ritchey detailed the difference between Petitioner’s episodes.
Id. at 69. When Petitioner is “trapped in her body,” Mr. Ritchey explained, “her eyes are wide
open.” Id. When Petitioner is tired, “she’ll go close her eyes and sleep and try to sleep it off.”
Id. Mr. Ritchey said that Petitioner would have an episode “seconds to minutes” after an
emotional moment occurred. Id. at 70.

                          iv. Petitioner’s Friend

        Ms. Sanders first met Petitioner in kindergarten, and they were “inseparable” until Ms.
Sanders moved to Indianapolis during their middle school years. Id. at 73. Petitioner and Ms.
Sanders reunited in 2009, and “picked up where [they] left off.” Id. at 74. Ms. Sanders still
resides in Kokomo, a city in Indiana fifteen minutes away from Petitioner’s former residence.
Id. at 73. Ms. Sanders testified that prior to Petitioner’s flu vaccination, the two would often see
each other and talk on the phone in the mornings when Petitioner was on the way to work. Id. at
75. Ms. Sanders said that she knew Petitioner was very busy as a manager for Frito-Lay, and
was very healthy prior to the onset of her narcolepsy. Id. at 75-76.

        It was “much later,” after Petitioner’s vaccination, that Ms. Sanders noticed a change in
Petitioner. Id. at 76. Ms. Sanders remembered that Petitioner was in bed “for two weeks
straight.” Id. Ms. Sanders stated that Petitioner was also “tired all the time” and “would have a
rough time staying awake while she was at work.” Id. at 76-77. Petitioner would call Ms.
Sanders while driving “on [Petitioner’s] way home just to help her stay awake, . . . because she
was afraid she was going to fall asleep.” Id. at 77. Ms. Sanders also remembered one instance
where Petitioner “blacked out for just a second and went off the road.” Id. Petitioner came to,
Ms. Sanders recalled, as she was “c[oming] to a stop before she hit [a telephone pole].” Id.

        Ms. Sanders recalled the first time she witnessed Petitioner have an attack. Id. at 78. Ms.
Sanders testified that she was at a bonfire with Petitioner’s family when she “noticed [Petitioner]
was kind of staring off into the distance.” Id. Ms. Sanders said that Petitioner’s mother “told
[Ms. Sanders] that’s what [Petitioner] does[;] she said [Petitioner] is having one of her episodes.”
Id. Petitioner was “just staring off into space,” and Ms. Sanders went to hold Petitioner’s hand to
talk to her during the episode. Id. When Petitioner came to, Ms. Sanders “noticed [Petitioner]
had a single tear come down her eye,” and “it scared [Ms. Sanders] to death.” Id. After this
episode, Petitioner’s husband helped put Petitioner to bed, and Petitioner “was so emotionally

                                                 28
drained that she’d just cry.” Id. at 79. When asked what kind of conversation they were having
prior to the episode, Ms. Sanders answered that “it was probably something that was . . . comical,
like lighthearted . . . .” Id. at 80. Petitioner’s staring episode lasted “at least five minutes, maybe
longer,” Ms. Sanders explained. Id. Ms. Sanders recalled another time that Petitioner had a
staring episode while Ms. Sanders and Petitioner were “sitting on the steps in her house.” Id. at
81. In this instance, Petitioner “just got to a blank stare” for “a couple minutes.” Id. After these
episodes, Petitioner told Ms. Sanders that Petitioner could hear her, but not react. Id. Ms.
Sanders testified about one instance after Petitioner had to stop driving and Ms. Sanders had to
drive Petitioner to work. Id. at 82. It “was around the holidays,” and Ms. Sanders said that
Petitioner’s work was “pretty busy” due to the time of year. Id. Ms. Sanders drove Petitioner to
her warehouse where “they were doing inventory.” Id. Ms. Sanders testified that when they
arrived, Petitioner felt that “she was going to . . . fall out.” Id. Petitioner then retreated to her
office, Ms. Sanders recalled, and “sat there for a while and just laid her head down.” Id.

        Ms. Sanders testified that Petitioner would “stumble a little bit” and told Ms. Sanders of
one instance where Petitioner fell down and broke her glasses. Id. at 82-83. Petitioner told Ms.
Sanders that Petitioner went downstairs “to get some ice cream or something,” and broke her
glasses while falling. Id. at 83. Ms. Sanders said that she was “always worried about
[Petitioner] being by herself,” and described how Petitioner had lost her independence since the
onset of her narcolepsy with cataplexy. Id. Ms. Sanders also testified that she has telephone
conversation with Petitioner “once or twice, three times a week” now that Petitioner lives in
Minnesota. Id. at 84. Ms. Sanders explained that Petitioner sometimes has an episode during
these calls, “because we’ll be talking and all of a sudden she’s not there.” Id. Respondent did
not cross-examine Ms. Sanders. Id. at 85.

                           v. Petitioner’s Neighbor

        Ms. Gilmore is Petitioner’s friend and neighbor, and has known Petitioner since March of
2017. Id. at 90. Ms. Gilmore sees Petitioner “almost daily.” Id. Ms. Gilmore described four
instances where Petitioner experienced a cataplectic episode. Id. at 90-91. Ms. Gilmore recalled
an instance wherein a car pulled out in front of Ms. Gilmore’s car while Petitioner was in the
passenger seat. Id. at 91. Ms. Gilmore stated that Petitioner had a “startled look,” said “‘I need a
minute,’ and then all of a sudden [Petitioner] was out,” Ms. Gilmore said. Id. Petitioner’s
episode lasted “four, five minutes,” and she could not respond to Ms. Gilmore. Id. Ms. Gilmore
said that she pulled over when Petitioner had her attack, “because [Ms. Gilmore] was kind of
shocked.” Id. at 92.

        Ms. Gilmore also recalled another time she witnessed Petitioner have a cataplectic
episode. Id. at 93. Ms. Gilmore and Petitioner were leaving “Minnesota’s largest candy store,”
in Ms. Gilmore’s car and entered traffic. Id. Ms. Gilmore “didn’t know if [Petitioner] just got
overwhelmed[,] . . . [but] [Ms. Gilmore] looked back over at [Petitioner] and she was out.” Id.
Ms. Gilmore said that Petitioner’s eyes were closed during both of these attacks, and Petitioner
was out for “probably four, five minutes” during the second attack. Id. Ms. Gilmore spoke of
another instance where she saw Petitioner have a cataplectic attack. Id. at 94. Ms. Gilmore said
that she and Petitioner were shopping at Walmart in Arnold’s Park, Iowa. Id. As they both
entered Ms. Gilmore’s car, Ms. Gilmore turned and saw Petitioner asleep in the passenger seat.

                                                  29
Id. Ms. Gilmore testified that Petitioner’s attack lasted “six, seven minutes” in the parking lot.
Id. at 95. The other time Ms. Gilmore saw Petitioner suffer an episode involved Petitioner’s
dogs’ barking. Id. Ms. Gilmore stated that “the dogs started barking,” and “then all of a
sudden . . . [Petitioner] went down.” Id. Petitioner fell in the grass with her eyes closed. Id.
Ms. Gilmore speculated that the dogs’ barking “[m]aybe raised her anxiety level,” but she was
“not sure.” Id. at 95-96. Petitioner damaged her glasses falling in the grass, and Ms. Gilmore
took Petitioner to have her glasses repaired a few days later. Id. at 96. Respondent did not ask
any questions of Ms. Gilmore. Id. at 97.

                          vi. Petitioner’s Husband

        Mr. Dougherty first met Petitioner in 2008 when they started dating, and in 2009,
Petitioner moved in with Mr. Dougherty. Id. at 100. They married in 2012. Id. at 99. Mr.
Dougherty said this about Petitioner’s work area: “She covered two districts . . . . [S]he pretty
much had two jobs, doing the work of two district managers.” Id. at 100. Mr. Dougherty stated
that the development of her condition has “been gradual” following her Fluzone vaccine. Id. at
102. In the beginning, “once a week, [Petitioner would] say she had to pull over, just exhausted,
[and] not knowing what’s going on.” Id. at 103. Her symptoms then increased, Mr. Dougherty
said, “to where she had the blackout episode behind the wheel.” Id.

        Mr. Dougherty testified that Petitioner’s episodes “were probably first noticeable March,
April 2013.” Id. The first episode Mr. Dougherty saw was during a family cookout at his and
Petitioner’s house to watch an Ultimate Fighting Championship (“UFC”) fight. Id. Mr.
Dougherty stated that it appeared like “Petitioner was in a coma with her eyes wide open[;] [she]
would not move, lift her arm, nothing . . . .” Id. Mr. Dougherty said that Petitioner “understands
what’s going on around her, but she cannot react.” Id. This incident occurred “probably right
around the Fourth of July episode,” Mr. Dougherty estimated. Id. at 104. Mr. Dougherty
eventually clarified that Petitioner had two episodes on the Fourth of July, one in the garage and
one in the kitchen. Id. Mr. Dougherty recalled that the second incident occurred “late, probably
eleven o’clock,” and Petitioner had a cataplectic episode at the kitchen table. Id. at 105.
Petitioner went limp, and her eyes remained open. Id. Mr. Dougherty testified that there is a
pattern to Petitioner’s episodes. Id. at 106. “[I]t all seems to do with emotions,” Mr. Dougherty
stated, “I’ve seen it to where if she’s upset, she gets sleepy or disordered.” Id. Petitioner’s
husband also mentioned episodes following “over excitement and she just completely collapses,
whether it be a scared reaction, a loud yell.” Id. Mr. Dougherty described one instance where he
“was joking around with [Petitioner],” and tapped the brakes while driving. Id. He said that “it
was like turning an on and off button on her.” Id. Petitioner began to react, but “[then] she was
just out,” Mr. Dougherty stated. Id.

        Mr. Dougherty also described an incident, “as little as a month ago,” where Mr.
Dougherty’s son “came up behind [Petitioner] and scared her and just grabbed her and said,
‘Hey.’” Id. at 106-07. Mr. Dougherty explained that his son had recently moved to the area and
had not been around Petitioner. Id. at 107. Mr. Dougherty said that he was “a hundred yards
away . . . , and then I see this going on . . . .” Id. Mr. Dougherty stated that he yelled “‘[g]rab
her,’ and she just collapsed.” Id. After Petitioner fell, Mr. Dougherty and his son carried her to

                                                 30
Mr. Dougherty’s truck. Id. Mr. Dougherty said that during the first year of Petitioner’s
incidences, her eyes would remain open while she was cataplectic. Id.

         That has changed, according to Mr. Dougherty, and whether it’s her medication or
something else, “it just puts [Petitioner] into sleep mode.” Id. Mr. Dougherty testified that
Petitioner had four such episodes in court that day. Id. During these episodes, Petitioner “just
closes her eyes and you can’t get any reaction out of her, for two to three minutes, and it’s
emotions.” Id. at 108. Mr. Dougherty noted that earlier that day, Petitioner had an episode after
she and Mr. Dougherty were delayed in reaching the courthouse. Id. Mr. Dougherty reiterated
that Petitioner’s episodes are “all tied to emotions.” Id. For instance, Mr. Dougherty described
how Petitioner saw several small children walking together in the courthouse, and “then she
came down to the bench and she’s out.” Id. Mr. Dougherty also mentioned that the stressors of
their financial situation, their mothers living with them, and their moves seem to contribute to
Petitioner’s episodes. Id. at 109. Mr. Dougherty testified that Petitioner’s sickness has made
their income level drop from $260,000 a year to “probably” $120,000 a year. Id. at 110.
Consequently both their cars were repossessed and their house entered foreclosure. Id. Mr.
Dougherty testified that the family moved to Minnesota because he “had the opportunity to
financially make things better for [them,]” and Petitioner’s condition had made it impossible for
her to continue her job at Frito-Lay. Id. at 111.

        Mr. Dougherty said that Petitioner was just awarded social security disability benefits,
but otherwise has no current sources of income. Id. Prior to Petitioner’s condition, she and Mr.
Dougherty would work “sometimes [seventy] hours a week” but would “have a good time” on
their days off. Id. at 112. As a result of her condition, Mr. Dougherty testified that Petitioner
can no longer participate in the activities that she used to enjoy. Id. Mr. Dougherty spoke of one
incident in a pool, where Petitioner had an episode “on a floaty by herself.” Id. Mr. Dougherty
jumped into the pool “and stayed with [Petitioner] until she came out of it, which was four, five
minutes.” Id. at 113. Mr. Dougherty testified that Petitioner’s episodes can vary in length “from
[two] to [three] minutes to [ten] to [fifteen] minutes.” Id. Initially, Petitioner’s episodes were
“with her eyes open,” and would last “two to three minutes.” Id. Over time, Mr. Dougherty
noted a pattern stating, “this seems like the more emotional that it is, the longer that it takes her
to come out.” Id. For the more emotional episodes, Mr. Dougherty stated that, it can take fifteen
to twenty minutes before Petitioner returns to her normal state. Id. at 114.

        Mr. Dougherty testified that he has been with Petitioner during her medical appointments,
and detailed one instance where Petitioner had an episode in a doctor’s office. Id. at 114-15.
Mr. Dougherty stated that Dr. Hemelt witnessed a cataplectic attack and had never seen anything
like Petitioner’s symptoms. Id. at 115. Mr. Dougherty ended his direct testimony by noting that
Petitioner takes Xyrem at night, and Effexor and Nuvigil during the day. Id. at 115-16.

        On cross-examination, Mr. Dougherty further distinguished Petitioner’s types of
episodes. Id. at 117. “Emotional is more a blackout,” Mr. Dougherty explained. Id. Other
times, “[w]e can argue, whether it be over bills or insurance or something like that, and it’s more
of a sleepiness.” Id. Mr. Dougherty stated that during the latter episodes, Petitioner can feel a
sleepiness coming on. Id. at 118. At that point, “she’ll say, ‘Hey, I need to go lay down,’ or get
away.” Id. “[B]ut the extreme emotions,” Mr. Dougherty said, “I mean, that’s—somebody

                                                 31
turned the switch off.” Id. Mr. Dougherty explained that when Petitioner has a sudden attack,
“she goes blank . . . . [S]he just collapses.” Id. Respondent questioned Mr. Dougherty’s
knowledge about Petitioner’s stressors, including her stepson. Id. at 119. Mr. Dougherty’s son’s
tendency to get in and out of trouble is documented on Petitioner’s medical record as a stressor.
Id. Mr. Dougherty responded that Dr. Neumann “kind of understood my son [was] in and out of
trouble with school and things like that.” Id. at 120.

        On re-direct examination, Mr. Dougherty described the incident where Petitioner fell off
of the toilet. Id. at 121. Mr. Dougherty testified that Petitioner “got up to go to the restroom,
and I hear a big thump, and . . . she’s laying on the ground from the toilet with a hole in the
wall.” Id. at 121-22. Mr. Dougherty said Petitioner was unconscious when he found her. Id. at
122. Mr. Dougherty testified that this incident happened “probably [in] 2015” after “one of the
UFC fights, [around] one o’clock in the morning.” Id. at 123. In response to a question from the
undersigned, Mr. Dougherty said that Petitioner had collapsed, “kind of like the overexcitement
of when she just collapsed.” Id. Mr. Dougherty also stated that Petitioner told him she could
remember collapsing, but not hitting the wall. Id. at 124.

                          vii. Ms. Marsha Dougherty, Petitioner

        Petitioner began her testimony detailing her former job with Frito-Lay. Id.at 125-26. In
2008, she was transferred to Indiana to work a district “that did $8 million a year in potato
chips.” Id. at 126. She held her job as a district sales leader until she “left in March of 2014.”
Id. at 127. Petitioner testified that she and her husband were on the same career track at their
respective employers and purchased a house in Galveston in 2009. Id. at 127-30. Petitioner
stated that her mother moved in after her house burned down in 2012. Id. at 130. At that time,
Mr. Dougherty’s mother, Petitioner’s mother, Petitioner’s children, and Mr. Dougherty’s
children all lived in the same house. Id. at 130-31. During this time, Petitioner recalled working
“probably [sixty], [seventy]” hours a week. Id. at 131. Petitioner testified that “four to five
weeks” after her vaccination on November 7, 2012, she “could not understand why [she] could
not get out of bed.” Id. at 133-34. Petitioner testified that she never had issues getting up in the
morning previously, but following her vaccination, “[she] couldn’t stay awake.” Id. at 134.
Petitioner “tried everything” to wake up, but she found herself only rising out of bed to eat “for
two weeks.” Id. at 135. Due to this two-week period of sleepiness, Petitioner recalled that she
missed a large company meeting hosted by Frito-Lay, “when all the new products come out,”
known as “the Blue Chip.” Id. Petitioner expressed disappointment that she missed the meeting,
and “all of the new mission states for that year[,] what our goals are[,] . . . and a lot of team
building.” Id.

        After she missed the meeting, Petitioner recalled that she was able to return to work;
however, she was still tired. Id. at 136. At this time, Petitioner began to drink several
caffeinated beverages a day, but “it didn’t make a difference.” Id. During the first week after
her return, Petitioner testified that she would pull over “at least once a day” due to her sleepiness.
Id. at 137. Petitioner remembered that she had three stops on the way to work that she could pull
into in order to rest. Id. at 137-140. Petitioner testified that she “never went to sleep” after
pulling over. Id. at 138. Instead, she stated that she would “just lay there[,] . . . like I knew what
was going on.” Id. Petitioner would then “come back up, . . . and go on [her] way.” Id. at 138.

                                                 32
This process of stopping to rest lengthened Petitioner’s commute to work from fifty minutes to
“[a]bout an hour and a half.” Id. at 140. Throughout 2013, Petitioner continued to make her
sales goals, but began to slow down “when [she] . . . hit the telephone pole.” Id. at 140-41.
Petitioner described the episode “right before Labor Day” in 2013 when she stopped at a stop
sign. Id. at 141. She testified that “the next thing I know I look up and there’s a telephone pole
right there in front of me and I just winged the wheel.” Id. at 141-42. Petitioner avoided striking
the telephone pole, but could not recall that she crossed into on-coming traffic and veered off of
the road. Id. at 142. Petitioner recalled “too many times” where she “came close to . . . colliding
with something.” Id. at 144. Petitioner stated that after the telephone pole incident, Dr.
Neumann advised her against driving “‘until we figure out what’s going on.’” Id. at 145-46.
Petitioner recalled that she told Dr. Neumann in September of 2013 that the flu vaccine had
caused her narcolepsy. Id. at 146. Petitioner believed this “[b]ecause there’s nothing else that
could. I didn’t do anything different.” Id. Petitioner remembered that Dr. Neumann said that
“she had not heard anything” regarding a connection between the flu vaccine and narcolepsy. Id.
at 146-47.

        Petitioner testified that she was first diagnosed with narcolepsy in September of 2013. Id.
at 147. Petitioner said that they started her on Ritalin then; however, she could not sleep on the
drug. Id. Petitioner and her physicians then started to experiment with other pharmaceuticals in
order to determine the best treatment regimen. Id. at 148. In November of 2013, Petitioner
returned to work after she began her narcolepsy treatment. Id. Petitioner explained that it was
during this time that she began to experience cataplectic episodes. Id. at 149. Petitioner recalled
one instance where she began staring at the television during a Green Bay Packers game. Id.
The Packers scored a touchdown, Petitioner said, and “[t]hat was what put me out.” Id.
Petitioner described that she can “feel [the attacks] coming on,” and her “body just gets tired.”
Id. at 150. Petitioner said that her eyes were open during this episode, allowing her to see the
television, but “[she] couldn’t move [her] eyes. [She] was like what the hell is going on?” Id.
This instance was the first of Petitioner’s cataplectic episodes. Id. at 151. Petitioner also stated
that she does not know how long her attacks last; “when you’re on the inside, . . . you don’t
know how long it is.” Id. “[I]f you’re in there for a couple minutes,” Petitioner said, “it could
seem like hours.” Id.

       Her second cataplectic attack occurred in April of 2014. Id. at 152. Petitioner stated that
she was out with her husband and his father on Mississinewa, a reservoir in east Indiana, when
the motor on their boat failed. Id. Petitioner began to feel anxious and said that before they
reached the dock, “I was just out.” Id. at 152-53. Mr. Dougherty and his father “had to sit there
and wait until it was over.” Id. Petitioner realized that she “[has] no control over” when these
cataplectic episodes occur. Id. at 154. The unpredictability of the attacks forces Petitioner to
remain “stuck at home,” either in her house or on her family’s farm. Id.

        Petitioner testified that she worked from November of 2013 to February of 2014, “[a]nd
during all these times I’m . . . better, but I’m not a hundred percent.” Id. at 148. But, in March
of 2014, Petitioner went on short-term disability “and never returned [to work].” Id. at 154. “It
wasn’t that I didn’t have the will,” Petitioner recounted. Id. Petitioner clarified, “I know I have
the will, but my body would not let me.” Id. Petitioner then discussed the treatment she
received for her narcolepsy, and how she was prescribed Effexor XR and Nuvigil. Id. at 154-56.

                                                33
Although it was originally helpful, Petitioner, stated that the Effexor XR was no longer
controlling her emotions or her cataplexy. Id. at 156. Petitioner stated that she was currently on
Effexor XR, Nuvigil, and Xyrem for her narcolepsy with cataplexy, and Claritin “every day.” Id.
at 157. Petitioner attested that she does not have high blood pressure. Id.

          Petitioner then described the incidents that occurred during the hearing. Id. She stated
that the first incident occurred during her mother-in-law’s testimony because “I had not seen . . .
how it hurts them or how it affects them.” Id. Petitioner was aware of her husband’s efforts to
wake her, but she remembers thinking at that time, “You’re just going to have to wait.” Id. at
158. Petitioner’s counsel apologized, and Petitioner responded that she has “dealt with this since
. . . I got that shot.” Id. She said that she “know[s] when they’re coming,” except for “when I
get scared, [] I get excited real fast, or some loud thing happens.” Id. Petitioner described one
instance when Ms. Gilmore set off fireworks next door, and she “just collapsed . . . [d]own in the
middle of the live room floor, just because of fireworks.” Id. at 158-59. When Petitioner can
feel an attack happening, she has an emotion, and “then all of a sudden I start to yawn, and I’ll
yawn and yawn, and I have to go sit down.” Id. at 159-60. Petitioner stated that she is aware of
her surroundings during these attacks, and she has become “used to it.” Id. at 160. “I’ve lived
with it for so long” that during attacks, she said she can think, “oh, you’re only [three and a half]
minutes in, you’re fine, no problem.” Id. Petitioner testified that there was no possibility that
she could return to work, and said that she has been awarded Social Security Disability benefits.
Id. at 160-61. Petitioner stated that, if she could, she would return to work “in a New York
second.” Id. at 161. She attested that she loved her work and “my people.” Id.

         During cross-examination, Petitioner described a usual day. Id. at 163. She wakes
“anywhere between 7:00 and 9:00,” makes a protein shake, and then waits for her Nuvigil and
Claritin “to kick in, get going . . . .” Id. Petitioner stated that she may start cleaning in the
kitchen at that point, but “might get halfway through doing some of it, and I end up back in the
chair or laying in my bed.” Id. Petitioner stated that she does not sleep once she lies back down,
noting that “the only time that I fall asleep is if I lay down in the afternoon, . . . and then I’ll take
about an hour and a half nap.” Id. at 164. Petitioner has been on this schedule “probably for
about the last three months, and it’s probably close to every other day or every day.” Id.
Petitioner explained that her naps are “not really sleep.” Id. She is still aware what is happening
in her surrounding, “but it’s deeper than just like a regular attack . . . .” Id. Petitioner continued
that her afternoon naps are similar to when “you hand falls asleep, [a]nd you can’t move.” Id. at
165. “But,” Petitioner said, “in the hour and a half in the afternoon, that is extremely intense.”
Id. Petitioner is in this state until her eyes open, “and then it starts from here down, to come out
of it.” Id. The process to come out of her cataplexy takes “30 to 45 seconds.” Id. Petitioner
stated that she sometimes feels refreshed after her episodes, “[b]ecause it’s almost like . . . my
body is [] regenerating itself.” Id. Petitioner explained that the short attacks, lasting five to ten
minutes, are similar to the longer episodes in that she can hear what is happening around her, and
she is “frozen solid.” Id. at 166. Petitioner also stated that she enters a “deep state . . . almost
immediately” upon lying down. Id.

        Petitioner stated that she tries to accomplish some things around the house after her
afternoon naps and tries to go to bed from 10 to 11 PM. Id. at 167. At bedtime, Petitioner stated
that she takes two doses of Xyrem and uses her CPAP machine. Id. at 167-69. Petitioner also

                                                   34
clarified that the incident where she fell off of the toilet occurred in 2015, but “[she] do[esn’t]
remember a lot about that.” Id. at 170. Petitioner stated that she is not able to organize things as
well as she used to due to her condition. Id. at 171. Petitioner also explained the medical record
notation from her October 17, 2013 visit with Dr. Hemelt that she thought her narcolepsy was
due to the flu vaccine. Id. Petitioner stated that her mother found “that there’s a connection”
between narcolepsy and the flu vaccine on Facebook. Id. at 171-72. Petitioner said that her
mother found information on the connection between Pandemrix and narcolepsy around three to
four months after her vaccination. Id. at 172.

                   b. Expert Testimony

                           i. Petitioner’s Expert, Dr. Marcel Kinsbourne

        Dr. Marcel Kinsbourne identified himself a “pediatric and behavioral neurologist” with
“an unlimited license to practice medicine.” Id. at 177. He first began his association with the
Vaccine Injury Compensation Program in 1988, with a “workshop for [prospective special
masters]” and a “lecture on neurology.” Id. at 177-78. After reviewing the medical records in
this case, Dr. Kinsbourne testified that he concluded Petitioner’s narcolepsy “was caused or
triggered by the influenza vaccination [] she [received] on November 7th, 2012.” Id. at 179-80.
Dr. Kinsbourne posited that “the most likely mechanism is an autoimmune attack on certain
neurons in the brain, and the influenza vaccine triggered that attack.” Id. at 180.

        Dr. Kinsbourne explained that the hypothalamus emits hypocretin, or orexin, during the
day to allow people to stay awake. Id. at 180-81. Dr. Kinsbourne stated that about 70,000
neurons secret this substance, which is then “picked up by so-called hypocretin receptors on
other neurons and stimulates them to activate various processes [to] keep the person awake.” Id.
at 181. Dr. Kinsbourne then explained that in narcolepsy, the “amount of hypocretin secreted . . .
is almost absent in many cases.” Id. This absence “appear[s]” to cause the “hypocretin
neurons . . . to die or disappear, gradually.” Id. Dr. Kinsbourne then said that he is “going to
present one theory as being medically reasonable but not as being proven.” Id.

        Dr. Kinsbourne cited the Ahmed and Steinman studies he relied on in his written report.
Id. at 182. He stated that both authors found antibodies to hypocretin receptors and postulated
that these antibodies are caused by a cross-reaction to protein present in both the vaccine and in
hypocretin receptors. Id. at 182-83. Damage to hypocretin receptors, Dr. Kinsbourne explained,
reduces the effect of hypocretin, because the process is “a feedback of excitation.” Id. at 182.
Dr. Kinsbourne testified that Ahmed and Steinman have “put into evidence that a nuclear protein
is present in varying amounts in different vaccines used for each H1N1 pandemic influenza
vaccination.” Id. at 183. “[W]hat [Ahmed and Steinman] claim in their publication is that the
more nuclear proteins there are in a particular vaccine,” Dr. Kinsbourne continued, “the more
likely that vaccine is to trigger narcolepsy, keeping in mind that’s still a very rare event.” Id.
Dr. Kinsbourne noted that, because narcolepsy is so rare, “it might not show up in
epidemiology.” Id. He went on to state that the vaccine with the highest amount of
nucleoprotein is the Pandemrix vaccination, “which clearly, indubitably caused narcolepsy in a
number of European countries.” Id. Dr. Kinsbourne explained that the Fluzone vaccine

                                                 35
Petitioner received does not have as much nucleoprotein as Pandemrix, but “still a [] large
amount compared to other vaccines.” Id. at 185.

        The other difference between Pandemrix and Fluzone, Dr. Kinsbourne stated, is that
Pandemrix is adjuvanted. Id. An adjuvant is “a substance which helps magnify the effects of the
vaccine.” Id. Dr. Kinsbourne opined that adjuvants are “used by manufacturers basically to save
money.” Id. at 186. “Instead of having a bigger dose of the virus [in the] vaccine itself, which is
expensive,” Dr. Kinsbourne continued, “an adjuvant enables you to get as a good or a better
effect with a smaller dose, somewhat smaller.” Id. Dr. Kinsbourne added that contrary to some
people, he does not believe that the adjuvant itself causes narcolepsy. Id. at 186-87. Dr.
Kinsbourne explained that the adjuvant “is also [present in] other vaccines that are not known to
cause narcolepsy,” such as the DTaP, HPV, pneumococcal, and HIV vaccines. Id. at 187. “So,”
Dr. Kinsbourne stated, “I don’t think anybody would argue the mere adjuvant is . . . the cause of
the narcolepsy regardless of which particular vaccine is being given.” Id. “It’s argued,”
however, “that something about the Pandemrix [vaccine] makes it unique in [causing]
narcolepsy.” Id. at 187-88. Dr. Kinsbourne then pointed out that “the very same adjuvant has
been given to a second vaccine, Arepanrix, . . . which does cause narcolepsy but very rarely
[compared to] Pandemrix.” Id. at 187-88. Additionally, Dr. Kinsbourne stated, Focetria, another
vaccine, is “adjuvanted and doesn’t cause . . . narcolepsy at all.” Id. at 188.

        Dr. Kinsbourne reiterated that he believes the nucleoprotein present in the Fluzone
vaccine causes narcolepsy, and that this nucleoprotein is also present in the wild H1N1 virus. Id.
at 188. Dr. Kinsbourne noted that “a well-known study in China shows that the . . . infectious,
H1N1 influenza virus can cause narcolepsy even in the absence of vaccination.” Id. at 189. Dr.
Kinsbourne clarified that adjuvanted flu vaccines are not used in the United States. Id.

        Dr. Kinsbourne then turned his attention to the Duffy study and noted that Dr. Jonathan
Duffy works for the Centers for Disease Control and Prevention. Id. at 190. Dr. Kinsbourne
referred to the study as “observational” and explained that the authors “ascertained a number of
cases called narcolepsy across two years, 2009 [and] 2010, and compared the number before
introduction of the [seasonal flu] vaccine and after.” Id. at 191 “And also, and in a way more
importantly,” Dr. Kinsbourne said, “they took the control data from a totally different study,
mainly one with the Mayo Clinic, in an area where the Mayo Clinic is located, called Olmsted
County.” Id. at 191-92. This Mayo Clinic study, Dr. Kinsbourne explained, was used to
“ascertain the . . . background rate, roughly per year, of what to expect in terms of numbers of
narcolepsy cases . . . .” Id. at 192. Dr. Kinsbourne then summarized that Duffy “had 870,000
people who were vaccinated that they picked up and did the study. And then they found, among
those people, [sixteen] cases that were chart[-]confirmed into the diagnosis of narcolepsy.” Id.
Focusing on “the key sentence,” Dr. Kinsbourne continued, “‘none have their symptoms onset
during the [one-hundred-and-eighty] days of the receipt of a 2009 pandemic vaccine compared
with 6.5 expected.’” Id. at 192-93. The Duffy study researchers “decided that they were looking
for narcolepsy cases that had begun within six months of their vaccination,” and the background
rate they were expecting from the Mayo Clinic study was 6.52. Id. at 193. Dr. Kinsbourne noted
that despite this expectation, “the number they found, amazingly, was zero.” Id. Dr. Kinsbourne
opined that “it’s beyond belief that in this period of six months after an influenza vaccination,

                                                36
nobody had narcolepsy, and yet a bunch of people did have narcolepsy within that two-year
period.” Id. at 194.

        “[I]n a normal epi[demiological] study,” Dr. Kinsbourne said, “you have a background
rate and then you see whether, in the period you’re examining, they’re significantly more than
the background rate.” Id. at 194-95. Instead, Dr. Kinsbourne elaborated, the Duffy researchers
saw “the background itself going away.” Id. at 195. Dr. Kinsbourne challenged the study,
stating, “[w]hat happened to the background, is the question.” Id. at 195. Dr. Kinsbourne’s
other objection to Duffy was that Petitioner was over forty when she had her onset of narcolepsy,
and Duffy did not have a background rate for her age group; in fact “[t]hey didn’t even consider
that narcolepsy would [at] all appear at that time.” Id. at 195-96. “So,” Dr. Kinsbourne said, “I
don’t think it really examines [Petitioner’s] case in this study.” Id. at 196. “[H]aving said this,”
Dr. Kinsbourne noted, “I think my confidence [in Duffy] [is] undermine[d] by this curious . . .
effect of zero versus a loss of background rate, relative to vaccination.” Id.

        Dr. Kinsbourne noted two other studies, one “by a Japanese researcher” that found
narcolepsy in all age groups though a study of autopsies, and Montplaisir, which found “one in a
million people had narcolepsy.” Id. at 196-97. Dr. Kinsbourne said that such a small number
would not concern epidemiology because that discipline is “concerned with public health,” not
“individuals.” Id. at 197. Dr. Kinsbourne continued that in Montplaisir, the researchers also
were blind to whether the narcoleptic had been vaccinated. Id. at 200. He contrasted this
methodology to the Duffy study where they were not blind as to vaccination. Id. This is
significant for Dr. Kinsbourne because “people have sometimes very emotional reactions for or
against vaccine risks and that complicates a person’s review, even unconsciously.” Id.

        Dr. Kinsbourne also noted that Petitioner tested positive for the genetic marker that
“makes her more susceptible to develop narcolepsy.” Id. at 202. People who have the HLA-
DQB1*0602 allele, Dr. Kinsbourne said, “pretty much exclusively . . . only get narcolepsy.” Id.
But, Dr. Kinsbourne conceded that “it is also a fact that many, many who, in fact, don’t get
narcolepsy also have it.” Id. at 203. He explained that this association is “compatible with our
theory, but it doesn’t necessarily make our theory that much stronger.” Id. Petitioner’s counsel
quoted Dr. Scammell’s assertion that “an immune stimulus, such as [an] infection” could trigger
“in genetically susceptible persons” an inflammatory reaction that could disrupt hypocretin
production “through a process of molecular mimicry.” Id. at 203. Dr. Kinsbourne agreed, but
emphasized that there is no evidence in the record that Petitioner had an infection “at a relevant
time” that could have caused her narcolepsy. Id. at 203-04. Dr. Kinsbourne concluded that
“there is no direct proof” that H1N1 causes narcolepsy, but based upon his research he concluded
“to a reasonable medical probability” that Petitioner’s flu vaccine caused her narcolepsy. Id. at
204-05.

         On cross-examination, Dr. Kinsbourne conceded that he has not had a formal clinical
practice since the “early 1990s.” Id. at 206-07. He stated that he “see[s] patients from time to
time, . . . in [his] home” for a condition he “discovered years ago.” Id. at 207. Dr. Kinsbourne
stated that, although he described himself as a pediatric neurologist, he has “held appointments
as [a] professor assistant [sic], [a] social professor of pediatrics, and an associate professor of
neurology.” Id. at 209. Dr. Kinsbourne also stated that “although [he] was chief of the pediatric

                                                37
section [of neurology], [he] worked in both [adult and pediatric neurology].” Id. His practice
does not involve “the treatment or diagnosis of sleep disorders,” and the last person he treated for
narcolepsy was “quite a while ago,” in the late 1980s or 1990. Id. at 209-10. Dr. Kinsbourne
stated that he diagnosed people with narcolepsy as a student, resident, and in his neurological
practice with children. Id. at 210. Dr. Kinsbourne conceded that his knowledge of the issues in
this case derives from the research he did for this case. Id. at 211. Dr. Kinsbourne agreed that he
does not have any “formal specialized education, training, or experience” in sleep disorders, and
he stated that he relied upon Petitioner’s tests to determine her diagnosis. Id. at 212. “I don’t
have to rely on somebody’s opinion here,” he said. Id.

        Respondent turned to Dr. Kinsbourne’s first report, based upon the De la Herrán-Arita
article. Id. at 213. Dr. Kinsbourne did not know if he had discussed the retraction of the article
in his report and explained that they failed to “find homology between the vaccine and the
hypocretin neurons in the hypothalamus.” Id. Dr. Kinsbourne claimed that “it is not essential
when proving an autoimmune attack by a vaccine or any substance, actually, to have found the
homology.” Id. Dr. Kinsbourne said that he “[had] no idea why [he] didn’t discuss the
retraction.” Id. He continued to champion the De la Herrán-Arita study, despite its retraction,
and stated that “it still seemed, to me, overwhelmingly likely that narcolepsy was caused by an
autoimmune process, even if we don’t know the homology that’s involved.” Id. at 215.
Respondent asked Dr. Kinsbourne if his first report was based upon an article that was retracted,
and Dr. Kinsbourne responded that, “No. there are numerous articles which state the opinion or
come to the conclusion that it is likely to be an autoimmune attack on . . . the hypocretin
neurons.” Id.

         Respondent then asked, “Can you point me towards the page or reference in your [first]
report . . . where you offer a theory other than the one based on the De la Herrán-Arita article?”
Id. at 215-26. Dr. Kinsbourne answered, “It’s the same theory, whether it’s based on the article
or not.” Id. at 216. Dr. Kinsbourne cited to the De la Herrán-Arita study to “give at least more
medical opinion” and noted that Dr. Scammell also thinks that “it’s an autoimmune process
that’s involved in causing narcolepsy.” Id. Dr. Kinsbourne stated that the retraction of the De la
Herrán-Arita study “doesn’t change my opinion.” Id. Dr. Kinsbourne clarified that he is not
relying upon the De la Herrán-Arita article to support his opinion that Petitioner’s flu vaccine
caused her narcolepsy and emphasized that the Ahmed and Steinman article, “which wasn’t
around when I did my first report,” provides the best support. Id. at 217-18. When questioned
about the timing of the Ahmed studies, Dr. Kinsbourne reversed course and agreed that “the
Ahmed studies that [he is] now relying on were already published at the time [he] wrote [his]
initial report in this case . . . .” Id. at 220. Dr. Kinsbourne added that he “could have
presumably, yes,” relied upon the Ahmed and Steinman study to base his opinion, but conceded
that “I can’t remember the logical contortions I went through to decide or to notice any of this.”
Id. at 220-21. “[O]n further consideration,” Dr. Kinsbourne then stated, “and particularly since
the retraction[,] it seemed to that [the Ahmed and Steinman study] will be the more reasonable
theoretical approach to offer – to show that indeed the H1N1 vaccine can cause narcolepsy.” Id.
at 221. Under Respondent’s questioning, Dr. Kinsbourne agreed with a quote from the Vassalli
letter that “‘until the pathogenicity of the reported anti-HCRTR2 antibodies is established, the
findings of Ahmed and colleagues should be considered as preliminary and not as evidence for

                                                38
molecular mimicry between H1N1 nuclear protein and HCRTR2, resulting in hypocretin
deficiency.’” Id. at 221-22.

         Returning to the Duffy study, Dr. Kinsbourne explained that he did not criticize Duffy for
being an observational study; “[i]t was a statement.” Id. at 222. Dr. Kinsbourne noted that an
observational study, “when done appropriately,” could “still provide some reliable evidence of
associations.” Id. Dr. Kinsbourne explained that “[i]t would have been . . . probably preferable
to have controls from the actual Duffy study than to have control from another part of the
country, but still acceptable.” Id. at 223-24. Dr. Kinsbourne added upon further reflection that
he didn’t “have an issue with [Duffy] using [the Mayo study] as a reference point.” Id. at 224.
Correspondingly, Dr. Kinsbourne stated that he did not have an issue with the Montplaisir study
also using the Mayo Clinic study as a reference. Id. at 225. Dr. Kinsbourne clarified that his
objection to Duffy was that they “report zero for what they actually find in a period for which
there must have been a base rate.” Id. A study should find a number that’s “comparable to the
base rate,” Dr. Kinsbourne explained, “[b]ut you wouldn’t expect suddenly nothing.” Id. at 226.
Dr. Kinsbourne found it unlikely “that just after a vaccination, there aren’t any cases [of
narcolepsy], and yet without a vaccination, there are a certain number, six cases, for a period.”
Id. at 227. Dr. Kinsbourne stated that he is not an epidemiologist, nor did he perform any
statistical analysis on Duffy. Id. Dr. Kinsbourne also clarified his prior criticism that, because
Duffy did not include any analysis of subjects within Petitioner’s age range, “[i]t’s not as
informative to this case . . . .” Id. at 228. Respondent highlighted that the Pandemrix studies
also did not investigate narcolepsy onset cases in subjects in Petitioner’s age range. Id. at 230.
Dr. Kinsbourne responded that Petitioner’s case “is a rare case,” and “[f]or something not to be a
signal in epidemiology, is not evidence against the existence of a rare case.” Id. Respondent
then asked what kind of study would be required to demonstrate a connection between Fluzone
and narcolepsy, if Duffy is unreliable. Id. at 231. Dr. Kinsbourne responded that a study
showing “a homology” would be required. Id. at 232. “If you have a homology,” Dr.
Kinsbourne said, “you don’t care about the epidemiology, because you have direct proof.” Id.
“We don’t have direct proof in this issue,” Dr. Kinsbourne stated. Id. at 232. He continued,
“There is no direct proof of anybody’s theory.” Id. “I’m offering a theory which was published
in peer-reviewed articles, and is one way of explaining what happened to [Petitioner].” Id. at
232. “I’m not asserting that it’s necessarily the case,” he continued, “[i]t’s not scientifically
certain.” Id.

        The undersigned asked Dr. Kinsbourne if he was relying upon an autoimmune reaction
based on homology, or on “the plausibility of molecular mimicry in this case?” Id. at 233. Dr.
Kinsbourne answered that he is relying upon the hypothesis put forward by Drs. Ahmed and
Steinman. Id. Dr. Kinsbourne also answered that he believed this hypothesis is specific enough
to apply to the Fluzone vaccine. Id. He explained that “in vaccines, you rarely have all the parts
[of a causation theory].” Id. at 234. Dr. Kinsbourne noted that has “some of the parts[,] . . .
enough parts to say that it’s more likely than not.” Id. at 234. The undersigned asked Dr.
Kinsbourne if he believed “it would ever be possible to develop a population-based study to
prove” his theory. Id. Dr. Kinsbourne believed that it would be cost-prohibitive to assemble
“[ten] million people or whatever it is you need statistically to show an effect.” Id. Dr.
Kinsbourne concluded his testimony by stating that he believes his causation theory meets the
Althen criteria. Id. at 236.

                                                39
                            ii. Respondent’s Expert, Dr. Scammell

        Dr. Thomas Scammell is a Professor of Neurology at Beth Israel Deaconess Medical
Center and has “a 10 percent appointment at Boston Children’s Hospital.” Id. at 244. He is also
the division chief for sleep medicine in the neurology department and undertakes research in
narcolepsy and other sleep disorders. Id. Dr. Scammell stated that he conducts research three
days a week and the rest of his time is spent in a clinical setting. Id. Dr. Scammell also noted
that he was involved in drafting the International Classification of Sleep Disorders by the
American Academy of Sleep Medicine. Id. at 245. In his clinical practice, Dr. Scammell
currently cares for “about [sixty]” patients with sleep disorders. Id. at 246.

        Dr. Scammell testified that he and his colleagues take narcolepsy very seriously,
“because, as best we understand it, narcolepsy is a lifelong diagnosis.” Id. Due to the permanent
aspect of the diagnosis, he explained that “you want to be sure that you’re calling it right.” Id.
For himself and other doctors settling on that diagnosis, “we really want to get a very careful
medical history, we want to do a careful physical exam, and we want to have really high-quality
sleep lab tests to be confident that we’re making the right diagnosis.” Id. Dr. Scammell stated
that “a lot of the diagnosis is in the history [and] listening to the patient’s story . . . .” Id. Dr.
Scammell continued that once he and his colleagues have the patient’s medical history, “we do a
physical exam, which is usually normal, and the sleep studies.” Id. at 247. Dr. Scammell
explained that there are “very precise rules about how to do a good set of sleep studies[,] and
then you also have to acknowledge that the tests have some limitations too.” Id. Dr. Scammell
explained that “we do an overnight sleep study [to diagnose narcolepsy], also called a
polysomnogram, where we record brain activity, muscle activity, and so forth.” Id. at 249. Dr.
Scammell continued that the next day, they perform the multiple sleep latency test, “and it’s the
combination of these two tests together that really is diagnostically useful.” Id. The first test is
“probably the most important role . . . [in] that it helps us look for other sleep disorders . . . .” Id.
Dr. Scammell noted as an example that Petitioner’s polysomnogram showed that Petitioner has
sleep apnea. Id.

         Dr. Scammell then noted that the “only other symptom that’s really specific to narcolepsy
is cataplexy.” Id. It is similarly important to listen to the patient’s history in making a diagnosis,
because “we end up putting a lot of weight on the sleepiness itself and the cataplexy” due to the
occurrence of other symptoms in the general population. Id. at 248. In overnight sleep studies of
people who have narcolepsy with cataplexy, Dr. Scammell stated that “a third of the time it
shows that the patient goes into REM sleep very quickly.” Id. at 249-50. People with narcolepsy
also fall sleep “very, very quickly at night on the polysomnogram.” Id. at 250. “So,” Dr.
Scammell said, “if somebody has an essentially normal polysomnogram, [the physicians have]
dealt with other sleep problems, and [the patient is] on no psychoactive medications, then we can
really trust the results of [the] multiple sleep latency test.” Id. This test involves asking the
individual “to try to fall asleep about every two hours, five times across the day,” Dr. Scammell
stated. Id. Dr. Scammell continued that physicians look for “how quickly does the person fall
asleep, and do they go into REM sleep during those daytime naps.” Id. It is “very unusual for a
person to have REM sleep during the daytime,” unless they are on certain psychoactive
medication or have narcolepsy, Dr. Scammell explained. Id. at 250-51. If physicians see a
patient, across all five naps, “fall[] asleep, on average, in less than eight minutes, and if at least

                                                   40
two of the naps contain REM sleep, then we consider that supportive evidence for narcolepsy.”
Id. at 251. But, Dr. Scammell cautioned that the multiple sleep latency test “is not proof in itself
that a person has narcolepsy, because we know that the test can be falsely positive sometimes or
falsely negative.” Id.

        Prior to the multiple sleep latency test, Dr. Scammell continued, “we try our best to ask
patients to discontinue” certain medication that can alter the effects of the tests. Id. at 251-52.
These medications include “pretty much any medicine that affects the brain,” including any
sedating medicines or stimulants, and any antidepressants. Id. at 252. Dr. Scammell said that his
office instructs patients to “stop antidepressants about three weeks before the [multiple sleep
latency] test, stop stimulants and sedatives a week before, and at least for the week running into
the test” to try to get seven-and-a-half to eight hours of sleep every night. Id.

        Turning to Petitioner’s case specifically, Dr. Scammell explained that her symptoms were
predominantly, from her medical records, “sleepiness and these episodes of staring,
unresponsiveness.” Id. at 253. Narcolepsy type one, narcolepsy type two, and other sleep
disorders were thus considered by Dr. Scammell in analyzing Petitioner’s case. Id. Dr.
Scammell explained that he approached Petitioner’s diagnosis of narcolepsy with some
skepticism, but he ultimately stated that narcolepsy would be on the list of differential diagnoses
he would make for Petitioner. Id. at 254, 260.

         Dr. Scammell also expressed his skepticism towards Petitioner’s diagnosis of cataplexy.
Id. at 254. Because cataplexy occurs “in almost no other medical disorders [than narcolepsy],”
Dr. Scammell reasoned that it is important to have an understanding whether a patient has it in
order to make a firm diagnosis of narcolepsy. Id. at 254-55. Dr. Scammell defined cataplexy as
“emotionally triggered episodes of muscle weakness.” Id. at 255. In fact, “many patients,” Dr.
Scammell continued, “can identify specific emotions that trigger” cataplexy. Id. What Dr.
Scammell gleaned from Petitioner was that she was triggered “where something unexpected and
really positive happens.” Id. Dr. Scammell stated that this “is a very typical thing to cause an
event of cataplexy.” Id. But, Dr. Scammell continued, Petitioner’s cataplexy is atypical. Id. at
256. Dr. Scammell explained that normal cataplexy first presents with “partial weakness . . . .
It’s pretty rare for people to suddenly fall to the ground.” Id. During a typical cataplectic
episode, Dr. Scammell continued, a person can’t respond, but “after a minute or two, sometimes
three at most, the cataplexy resolves, and they’re able to give a good explanation of what
happened during that.” Id. In Petitioner’s case, Dr. Scammell stated there was not a consistent
trigger for her events, and it’s very unusual for someone’s eyes to remain open during a
cataplectic episode. Id. at 256-57. One of the first things usually affected with cataplexy, Dr.
Scammell noted, are the eyelids, and “people sort of look sleepy because the face becomes slack
and the head bobs forward.” Id. at 257. In fact, Dr. Scammell noted, “almost everybody has this
facial weakness as part of [their cataplexy],” but “[t]here are rare patients where they may have
other parts of the body affected . . . .” Id. Additionally, Dr. Scammell stated that Petitioner has
unusually long cataplectic episodes, as most cataplectic spells last “for a few seconds, to, you
know, a handful of minutes, two, three minutes at most.” Id. at 258. The last atypical aspect of
Petitioner’s condition is that, after she recovers from her spells, she is tearful and upset, where
normally, “over the course of a few seconds [after a cataplectic incident], they’re better.” Id. at
258-59.

                                                 41
        Dr. Scammell acknowledged that “in clinical medicine, everybody is different and people
have different triggers, people have different symptoms, and there certainly is a spectrum.” Id. at
259. After hearing witness testimony in this case, Dr. Scammell stated that, “I’m still not fully
convinced that [Petitioner] has narcolepsy, but I think it’s . . . on the list.” Id. at 260. Dr.
Scammell noted that there are some other disorders that could explain Petitioner’s sleepiness,
“[a]nd it’s possible that some of these factors or some combination of them is accounting for the
overall picture.” Id. Dr. Scammell explained that the incident where Petitioner was on the toilet
and fell into the opposite wall could be explained by her taking Xyrem, but he did not have
enough information to know for certain. Id. at 261-62.

         Respondent then asked Dr. Scammell whether Petitioner’s sleep apnea could contribute
to her symptoms. Id. at 262. Dr. Scammell noted that there “was this honeymoon period after
starting the CPAP when it sounded like, from the description in the notes, that her sleepiness got
better, to the point where her doctor stopped some of her narcolepsy medicines.” Id. CPAP
“doesn’t do anything for narcolepsy,” Dr. Scammell said, so this period of improvement “would
suggest that at least some of the sleepiness could be due to sleep apnea.” Id. at 263. It is, in fact,
“very common,” for narcoleptics to have other sleep disorders, Dr. Scammell attested, and he
and his practice “try to look for those alternative causes and really try to fix them as best we can”
because narcolepsy is incurable. Id. at 263-64.

         Dr. Scammell then noted that Petitioner tested positive for the HLA-DQB1*0602 allele
connected with narcolepsy. Id. at 265. Dr. Scammell explained that this allele appears in ninety
percent of people with narcolepsy type one and in about fifty percent of people with narcolepsy
type two, narcolepsy without cataplexy. Id. Unfortunately, Dr. Scammell continued, the allele
itself is not that helpful diagnostically because it also appears in twenty-five percent of the
general population. Id. “However,” Dr. Scammell explained, “if somebody has a story that’s
consistent with narcolepsy, their sleep tests are consistent with narcolepsy, and they carry the
gene, well, these things collectively help build a case and it makes the probability of that being a
diagnosis stronger.” Id.

         Dr. Scammell highlighted the issues with the diagnostic tests performed on Petitioner. Id.
at 266. On September 13, 2013, Petitioner had an overnight polysomnogram and a multiple
sleep latency test the next day, but both “had some issues which make them a little bit hard to
interpret[;] actually, in this case, more than a little hard. I would say difficult to interpret.” Id.
First, Dr. Scammell stated, Petitioner only slept six hours during her polysomnogram, which is
“just on the edge of what we consider an adequate amount of sleep.” Id. at 267. This lack of
sleep, Dr. Scammell continued, would make it easier for a patient to fall asleep during the nap
test on the following day. Id. Dr. Scammell also explained that Petitioner had “less than the
usual amount of rapid eye movement sleep on that overnight test.” Id. This is common, Dr.
Scammell explained, “but it . . . raises a question of [whether] some medications were interfering
with REM sleep . . . .” Id. In fact, Dr. Scammell continued, Petitioner was taking escitalopram
at that time, “which we know alters REM sleep.” Id. at 267-68. Petitioner additionally did not
go into REM sleep within fifteen minutes of sleep onset, which is not “indicative of narcolepsy.”
Id. at 268. Dr. Scammell again raised the issue that Petitioner was on medication during the day-
time naps that is known to interfere with REM sleep and also noted that Petitioner was

                                                 42
additionally taking two sedating medications at the time of her test, topiramate and lorazepam.
Id. at 268-69. Dr. Scammell explained that these issues complicate Petitioner’s sleep study and
“make[] [the study] hard to interpret.” Id. at 260.

        Dr. Scammell stated that in narcolepsy with cataplexy, patients have “very little or no
detectable hypocretin or orexin in their spinal fluid.” Id. at 270-71. He noted that in Europe,
physicians “quite frequently now” will measure hypocretin levels in spinal fluid as a way to
diagnose narcolepsy. Id. at 271. In fact, in about ninety percent of people suffering from
narcolepsy with cataplexy, “the hypocretin levels are low or just plain undetectable.” Id.
Petitioner would benefit from such a test, Dr. Scammell said; however, there is no commercial
lab that runs the test in the United States. Id. at 272. Dr. Scammell noted that it would be
helpful, however, for Petitioner to undergo a “clean sleep study” where she has been off of any
psychoactive medication prior to the study, or to undergo a lumbar puncture to have a clear
picture of her diagnosis. Id. at 273-74. Dr. Scammell ultimately stated that “there’s about a
50/50 chance . . . that indeed there’s narcolepsy with cataplexy” in Petitioner’s case. Id. at 275.
Dr. Scammell highlighted the mediating factors to make him question Petitioner’s diagnosis,
including her descriptions of her cataplexy and the irregularities in her sleep study; but,
“everybody is different, and in the clinical world, we see a spectrum of symptoms.” Id. at 274-
75. If Dr. Scammell were caring for Petitioner, he would “like to see more objective evidence . .
. because, as I said before, it’s a lifelong diagnosis.” Id. at 275.

        Turning to Petitioner’s causation theory, Dr. Scammell began by referencing his article,
“Narcolepsy” from the New England Journal of Medicine. Id. at 276-77; Pet’r’s Ex. J. He stated
that “around 1998,” researchers made the connection between narcolepsy and the HLA gene, and
hypothesized that narcolepsy was an autoimmune condition. Id. at 277. “That was a long time
ago,” Dr. Scammell said, “and in the last, you know, 30-plus years, research have not found any
convincing evidence that really proves [the autoimmune hypothesis].” Id. Dr. Scammell
continued that the idea that an “inflammatory reaction damages the orexin-producing neurons,
perhaps through a process of molecular mimicry” is countered by the fact that “no signs of
inflammation are detected in cerebrospinal fluid or seen on magnetic resonance imaging.” Id. In
addition, Dr. Scammell noted, “[T]here’s no strong evidence of an increased prevalence of other
autoimmune disorders among people with narcolepsy.” Id. Lastly, Dr. Scammell added that
immune system-altering drugs have been used on narcoleptics and “have not been helpful.” Id.
Dr. Scammell commented that the idea that an autoimmune reaction causes narcolepsy “is an
interesting idea,” but added, “it’s a hypothesis.” Id. at 279.

        Dr. Scammell then explained how hypocretin works in the brain. Id. He began that
“there are a cluster of neurons, brain cells that produce hypocretin, also called orexin.” Id. at
280. “These cells send connections to lots and lots of places in the brain, pretty much all of the
brain,” Dr. Scammell continued. Id. When those hypocretin neurons are stimulated, Dr.
Scammell said, “they release hypocretin, which has excitatory effects on those [target] neurons,
and it makes them fire more and wake up.” Id. In narcolepsy, when the hypocretin neurons die,
“those signals that help turn on lots of great regions are absent and people consequently end up
with chronic sleepiness and REM sleep is no longer properly controlled.” Id.

                                                43
        The Ahmed paper, Dr. Scammell said, “hypothesizes that there’s some autoimmune
process that acting upon hypocretin-2 receptors,” one type of hypocretin receptor that allows for
excitation of the target neurons. Id. at 280-81. “The fundamental problem with this idea,” Dr.
Scammell said, “is that those receptors are found in a tremendous amount of the brain.” Id. at
281. Dr. Scammell estimated that those receptors are found in thirty to fifty percent of brain
neurons. Id. If narcolepsy caused an autoimmune attack on these receptors, Dr. Scammell
reasoned, “you would have widespread damage across the brain.” Id. But, in narcoleptics, “we
see only a loss of the hypocretin neurons without damage to all these other brain regions.” Id.
Dr. Scammell explained that additional research would be needed to prove Ahmed’s hypothesis.
Id. at 282. Dr. Scammell noted that this is a “very active area of research[, with] [ten] or a dozen
research groups around the world that are now trying to find that evidence that there is an
autoimmune process that could cause narcolepsy.” Id. Dr. Scammell emphasized that “there’s
been dozens of papers written on this, but none of them really provide conclusive proof.” Id.

        Dr. Scammell then clarified that “it depends on which study you’re looking at” whether it
is ninety or ninety-eight percent of type one narcolepsy patients have the HLA gene. Id. at 283.
Dr. Scammell also attested that this fact does not have any relevance to the question of whether
the flu vaccine causes narcolepsy. Id.

         Respondent then turned Dr. Scammell’s attention to the Duffy study. Id. at 284. Before
addressing the study, Dr. Scammell clarified that the “general feeling is that narcolepsy affected
one in 2,000 people[,] and narcolepsy usually begins in children, typically in the teen years,
between ages [ten] and [twenty].” Id. at 285. Referencing the one in 2,000 number, Dr.
Scammell said that these cases occur without an understanding of “what the usual trigger and
factor is.” Id. at 285-86. Dr. Scammell reiterated the fact that it is unusual for someone to have
an onset of narcolepsy after the age of forty, like Petitioner; however, Dr. Scammell also noted
that “I’ve seen patients myself who have developed narcolepsy in their adults years, but
generally it occurs in children.” Id. at 286. Dr. Kinsbourne, Dr. Scammell said, relied upon the
Montplaisir study to say that there is a one-in-a-million chance of developing narcolepsy after flu
vaccination, and, when you consider that one in 2,000 people will develop narcolepsy normally,
“it’s hard to envision even designing and paying for a study that would actually be able to detect
an event of such rarity.” Id. at 286-87. Comparing these probabilities, Dr. Scammell concluded,
“it certainly seems like just getting narcolepsy for the usual reasons, whatever they might be, is a
much more likely event.” Id. at 287.

         The undersigned then questioned Dr. Scammell. Id. at 288. Dr. Scammell was first
asked whether Petitioner’s diagnosis of type one or type two narcolepsy has any bearing on
whether it is an autoimmune reaction. Id. Dr. Scammell stated that the influx in narcolepsy
cases following the use of Pandemrix “led many of us to think that narcolepsy is caused by a
combination of” genetics and an immune stimulus. Id. at 289. Importantly, Dr. Scammell said,
all of the patients who had narcolepsy following Pandemrix had very clear cases of narcolepsy
type one, or narcolepsy with cataplexy. Id. “I don’t believe that there’s any epidemiological
evidence, from other papers or other events, that suggest any increase with vaccines causing
narcolepsy type [two],” said Dr. Scammell. Id. at 289-90. Dr. Scammell explained that this
difference is why it is important to consider whether Petitioner has cataplexy, especially when
Petitioner has many atypical aspects of cataplexy. Id. at 290-91. Dr. Scammell also noted that

                                                44
Petitioner’s stories of having a cataplectic attack after being frightened are atypical, as “when
people are startled, they generally have an increase in muscle tone, not a decrease in muscle
tone.” Id. at 292. But, Dr. Scammell admitted that the touchdown story Petitioner told is “a
really classic trigger[,]” and he repeated his estimate that it was a 50/50 chance whether
Petitioner has narcolepsy with cataplexy. Id. at 290, 294.

                          iii. Respondent’s Expert, Dr. MacGinnitie

        Dr. Andrew MacGinnitie is the Clinical Director for the Division of Immunology at
Harvard Medical School, where he is also an associate professor. Id. at 195. He is also an
attending physician at Boston Children’s Hospital, where he sees patients two days a week. Id.
at 295-96. He manages the clinical and business operations of the Division of Immunology, and
conducts research, “particularly into food allergy and [a] rare illness called hereditary
angioedema.” Id. at 296. In his clinical practice, Dr. MacGinnitie primarily sees children with a
typical diagnosis of “dermatitis, food allergy, asthma, allergic rhinitis.” Id. Dr. MacGinnitie
also sees adult patients in five to ten percent of his practice, “particularly with immunologic
disorders.” Id.

        Dr. MacGinnitie first addressed Dr. Kinsbourne’s causation theory relying upon the
Ahmed hypothesis. Id. at 297. Dr. MacGinnitie stated that he does not think the Ahmed paper
provides “a coherent explanation that links the flu vaccine and specifically Fluzone to
narcolepsy.” Id. He reiterated Dr. Scammell’s point that hypocretin-2 receptors are found
throughout the brain, and the theory does not detail why researchers do not find widespread
damage due to the antibody if it were the cause. Id. Dr. MacGinnitie also noted that “there’s no
data [from studies] from patients who are vaccinated with nonadjuvanted vaccine[s] [who
develop narcolepsy].” Id. at 297-98. Dr. MacGinnitie explained that adjuvants “are a substance
that are added to a vaccine to increase the immune response . . . .” Id. at 298. Dr. MacGinnitie
stated that he doesn’t “have any particular knowledge” whether adjuvants are added to vaccines
to save money, as Dr. Kinsbourne attested. Id. at 299. But, Dr. MacGinnitie continued, “I know
that in particular, for younger children[,] the immune system is much weaker.” Id. Dr.
MacGinnitie continued, “So if you use nonadjuvanted vaccines in infants, you see a very weak
immune response, and so adding an adjuvant particularly in that age group will increase the
strength of the immune response.” Id.

        Returning to the Ahmed (2015) study, Dr. MacGinnitie explained that the existence of
the hypocretin-2 receptor antigens “could be a marker of the disease rather than a cause of
disease.” Id. at 300. In other diseases, “as an autoimmune attack occurs and the cells that are
being attacked die, they release other proteins that are often not exposed to the immune system . .
. .” Id. “[A]nd then,” Dr. MacGinnitie continued, “you can actually see antibodies against [the
other proteins] that aren’t causative of the disease but are just a marker of it.” Id. Dr.
MacGinnitie referenced the Kawashima, Bergman, and Saariaho articles as evidence that
researchers have found “a total of four . . . potential antibodies in [narcolepsy] and so whether
these are actually causative of disease or they’re just a marker is not clear.” Id. at 301 (citing

         Dr. MacGinnitie then provided background and explained that there are two “major parts
of what’s called the adaptive immune [system].” Id. at 302. These two parts are the B cell
mediated antibody system, and the T cell system. Id. B cells, Dr. MacGinnitie illustrated, “make
antibodies that are proteins in the blood” that bind to “whatever their target is, and if that was a
bacteria or a virus, it would either prevent infection or cause the infectious agent to be cleared.”
Id. “T cells,” Dr. MacGinnitie said, “are a little more complex.” Id. Dr. MacGinnitie continued
that the HLA antigens that are associated with the HLA gene “are expressed on all cells of the
body[,] and they pick up fragments of a protein called peptides.” Id. These HLA antigens bind
with peptides, and T cells “float around and look for the specific peptide in that specific HLA
type.” Id. Dr. MacGinnitie explained that narcolepsy type one is “almost entirely present in
patients who have a specific HLA type.” Id. The association between narcolepsy and a specific
HLA type “provides very strong evidence that T[]cells must be involved in the pathogenesis if it
truly is an autoimmune disease . . . .” Id. at 302-03. There is “a high degree of variability in
which HLA proteins people express, . . . [s]o we refer to this as a disease being HLA restricted.”
Id. at 303. Narcolepsy is thus “dependent on specific HLA types, . . . and that indicates an
obligate role for T[]cells in the disease.” Id. Dr. MacGinnitie explained that the De la Herrán-
Arita was appealing because “it really purported to demonstrate that these T[]cells were
present[,] and they were directed against hypocretin.” Id. Dr. MacGinnitie stated that because
we know hypocretin is HLA restricted, “[w]e have . . . T[]cells that we know must exist,” and De
la Herrán-Arita provided an explanation how these T cells target hypocretin. Id. at 303-04. This
hypothesis would have provided “a great explanation” of the mechanism behind narcolepsy if the
data therein were legitimate. Id. at 303.

       Dr. MacGinnitie explained that the Ahmed article does not provide any of the certainty
the De la Herrán-Arita article would have provided were it found to be reliable. Id. at 304. The
autoantibodies that Ahmed proposes are “less specific” than HLA-associated T cells, and the
Ahmed article does not provide “any evidence for T[]cell[]” involvement. Id. at 303-04. In fact,
Dr. MacGinnitie said, the Ahmed authors acknowledge that their inability to identify any T cells
is a “weakness of their paper.” Id.

        Dr. MacGinnitie explained that the “real weakness” of Ahmed is that their control groups
without narcolepsy have the antibodies Ahmed posits as causative. Id. at 305. For instance, Dr.
MacGinnitie commented, the authors of Ahmed found seventeen out of twenty people vaccinated
with Pandemrix had the hypocretin-2 receptor antibody, “which, right, that sounds pretty
impressive.” Id. The authors also had twelve people vaccinated with Focetria, a vaccine
adjuvanted similarly to Pandemrix, who did not have narcolepsy and did not have antibodies
against hypocretin-2 receptors. Id. But, Dr. MacGinnitie said, “roughly four or five” out of
twenty people who had narcolepsy not following vaccination also had antibodies, and, more
importantly, over half of the control group of eleven Finnish children “had antibodies against the
hypocretin receptor.” Id. “[I]t’s a little hard to square [Ahmed’s] findings of over half of normal

                                                46
children expressing antibodies against this receptor with [the antibodies] being causative.” Id. at
306. Dr. MacGinnitie also mentioned that the study was published in 2015, “and there’s been no
data since then.” Id. Dr. MacGinnitie quoted the Ahmed article’s noted limitations, “that the
findings reported in this study should be viewed as a step of understanding the mechanism of
vaccine-associated narcolepsy and will benefit from additional confirmatory studies . . . .” Id. at
308.

         Dr. MacGinnitie then addressed Dr. Kinsbourne’s argument that adjuvants could not be
the cause of narcolepsy because adjuvants are present in other vaccines. Id. at 309. Dr.
MacGinnitie said, “I think it’s a little bit misleading to say that many vaccines contain adjuvants,
[as] adjuvant is just really a term that we could define as a substance that’s not immunogenic in
itself,” meaning that it “does not cause [an immune] response to itself but increases the body’s
response to whatever it’s mixed with.” Id. “[T]here are a wide variety of substances that have
been used as adjuvants,” Dr. MacGinnitie continued, “for example, Pandemrix, and Arepanrix,
have a specific adjuvant that’s called ASO3, [which] is best described as oil and water, . . . an
emulsion . . . that’s added to [] these influenza vaccines.” Id. at 309-10. “[I]n DTaP and
HPV[,]” Dr. MacGinnitie explained, “[t]he adjuvant . . . is completely different.” Id. at 310. It is
a “salt of aluminum.” Id. Dr. MacGinnitie concluded, “And so I don’t think the fact that DTaP
or HPV vaccines have not shown an increased risk of narcolepsy really provides any evidence
that adjuvants couldn’t be involved . . . .” Id. It is very important “to realize that really the only
evidence for an increased risk of narcolepsy after influenza vaccine is with adjuvanted vaccines,”
Dr. MacGinnitie stressed. Id. Dr. MacGinnitie stated that he did not think “we could know the
answer” whether the adjuvant by itself is sufficient to cause narcolepsy.” Id. “[B]ut,” Dr.
MacGinnitie said, “it seems to me to be clear that the adjuvant is required.” Id. Dr. MacGinnitie
noted that adjuvanted vaccines have also never been used in the United States. Id. at 311.

        Dr. MacGinnitie then explained how differing manufacturing processes for vaccines can
affect how the vaccine triggers and immune response. Id. at 312. He stated that “early in the
year,” what experts believe will be the most prevalent flu strains are selected, “produced in mass,
and then isolated into vaccines.” Id. In Europe, they then add adjuvants to these vaccines, but in
the United States some additives are used. Id. Dr. MacGinnitie explained that “studies have
shown some differences among different preparations of vaccines even containing the same
strands, in terms of protein content and the amount of immune stimulus that’s given.” Id. These
differences can result from how “the proteins were isolated, which cell lines were used, etc.,” Dr.
MacGinnitie continued. Id. at 312-13. Dr. MacGinnitie then explained that it is unclear if the
wild-type virus can cause narcolepsy in itself. Id. at 313. He commented that inflammation can
be a trigger in other autoimmune diseases and that an influenza illness can cause inflammation
and a “very strong” immune stimulus. Id. 313-14. This strong stimulus could “break[]
tolerance” and cause an autoimmune reaction. Id. at 313-14. Dr. MacGinnitie then explained
that a wild-type infection would provide the strongest immune stimulus, followed by the
adjuvanted flu vaccine. Id. at 314. The unadjuvanted flu vaccine would then provoke the least
stimulating immune response of the three. Id.

        Addressing Duffy, Dr. MacGinnitie stated that “I thought it was a very strong study.” Id.
at 314. Dr. MacGinnitie said that he understood Dr. Kinsbourne’s criticism that they found zero
cases of narcolepsy compared to a background rate of “six or eight cases of narcolepsy.” Id. at

                                                 47
315. To begin, Dr. MacGinnitie stated, the researchers found sixteen cases of narcolepsy,
including two that had onset within one-hundred-and-eighty days of the 2010 to 2011 seasonal
vaccine. Id. Dr. MacGinnitie said that Dr. Kinsbourne critique that they “didn’t have the ability
to pick up narcolepsy cases” is unfounded, “because they did pick up narcolepsy cases. They
just saw less than expected.” Id. Dr. MacGinnitie also noted that he had not performed a
statistical analysis, but with any rare event, “there can be more variation than you might expect
than when you have a large population.” Id. Furthermore, with something as rare as one in a
million, “you could see significant variation in the actual count.” Id. That is why it is possible
that zero cases “was within the range of what could be not statistically significant for [the]
condition.” Id. at 316. Dr. MacGinnitie stated that Dr. Young’s inability “to identify or flag [the
found rate of zero as compared to the background rate] as a flaw in this study . . . confirmed [Dr.
MacGinnitie’s] belief that it’s a very strong study.” Id.

        Dr. MacGinnitie then addressed Dr. Kinsbourne’s use of the Montplaisir study. Id. at
317. Dr. MacGinnitie first stressed that Montplaisir concerns an adjuvanted form of the flu
vaccine, Arepanrix, and not the type of vaccine Petitioner received. Id. Then, Dr. MacGinnitie
emphasized that Arepanrix has more nucleoprotein than Pandemrix, which, according to
Petitioner’s causation theory, should make it more likely to cause narcolepsy. Id. But, Dr.
MacGinnitie continued, the level of risk “can only be detected at a level of one in a million, and I
think that really calls into question this idea that it’s the nuclear protein that is causative.” Id.

       Dr. MacGinnitie then turned to the Han study and noted its weaknesses, the failure to
separate the patients who developed narcolepsy into groups corresponding to vaccination and to
account for any other virus that was circulating in China at that time. Id. at 318-19. Dr.
MacGinnitie also cited to two other studies, one is the Choe study that “showed no increased rate
of narcolepsy” following both an adjuvanted and non-adjuvanted vaccination program in South
Korea. Id. at 320. In the Lee study, Dr. MacGinnitie noted that researchers found no specific
increase in any autoimmune or neurological disease following vaccination. Id. at 320-21.

       Dr. MacGinnitie concluded that there are two main weaknesses with Petitioner’s theory
of causation. Id. at 321. First, “it’s not a coherent story,” because the presence of hypocretin
receptor antibodies does not provide “a really good explanation” without some “evidence of
involved T[]cells . . . .” Id. Second, Dr. MacGinnitie continued, “there’s strong epidemiological
evidence against such an occurrence.” Id.

        The undersigned asked Dr. MacGinnitie whether there “is a potential autoimmune
pathogenesis for narcolepsy.” Id. at 323. Dr. MacGinnitie responded in the affirmative, but
clarified that Petitioner’s specific theory that “antibodies are generated against the hypocretin
receptor” is problematic. Id. Dr. MacGinnitie also explained that the immune responses to both
the wild-type virus and adjuvanted vaccines are different compared to non-adjuvanted vaccines,
“apples to oranges.” Id. at 324.

                          iv. Dr. Kinsbourne’s Rebuttal

       Dr. Kinsbourne retook the stand to clarify his criticism of the Duffy study. Id. at 325. He
explained that Duffy looked at two six-month periods of a year to see if any narcolepsy cases

                                                 48
developed during that time. Id. at 325-26. Duffy found that no narcolepsy cases occurred during
that year following vaccination, even though they proposed a background rate of six cases. Id. at
326-27. Dr. Kinsbourne commented that Duffy’s failure to find any narcolepsy cases “just
doesn’t sound right . . . .” Id. at 327. Dr. Kinsbourne said, “I don’t think one can just say, oh,
well, things vary.” Id. “I think it’s simply not believable that every one of the narcolepsy cases
in that year [were skipped] when it was only a year,” Dr. Kinsbourne continued. Id. Dr.
Kinsbourne concluded that “the Ahmed proposal” was a “medically reasonable mechanism,” and
that science was not able to give “a definitive answer; we don’t have that.” Id. at 331. The
“Ahmed proposal is science in the making,” Dr. Kinsbourne concluded, and “it does show what
[the Althen] criterion asks for, which is that to relate an H1N1 influenza vaccination to the
outcome of narcolepsy with cataplexy is biologically plausible.” Id.

         V.    The Applicable Legal Standard

        To receive compensation under the Vaccine Act, Petitioner must demonstrate either that:
(1) Petitioner suffered a “Table injury” by receiving a covered vaccine and subsequently
developing a listed injury within the time frame prescribed by the Vaccine Injury Table set forth
at § 14, as amended by 42 C.F.R. § 100.3; or (2) that she suffered an “off-Table Injury,” one not
listed on the Table, as a result of her receipt of a covered vaccine. See § 11(c)(1)(C); Moberly v.
Sec’y of Health & Human Servs., 592 F.3d 1315, 1321 (Fed. Cir. 2010); Capizzano v. Sec’y of
Health & Human Servs., 440 F.3d 1317, 1320 (Fed. Cir. 2006). Petitioner’s claim that her flu
vaccine caused her to develop narcolepsy with cataplexy does not fall within the Vaccine Table.
Thus, she must prove that her injury was caused-in-fact by the flu vaccine.

        To establish causation-in-fact, Petitioner must demonstrate by a preponderance of the
evidence that the vaccine was the cause of the injury. § 13(a)(1)(A). Petitioner is required to
prove that the vaccine was “not only [the] but-for cause of the injury but also a substantial factor
in bringing about the injury.” Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315,
1321-22 (Fed. Cir. 2010) (quoting Shyface v. Sec’y of Health & Human Servs., 165 F.3d 1344,
1352-53 (Fed. Cir. 1999)).

        In Althen v. Secretary of the Department of Health and Human Services, the Federal
Circuit set forth a three-pronged test used to determine whether a petitioner has established a
causal link between a vaccine and the claimed injury. See 418 F.3d 1274, 1278-79 (Fed. Cir.
2005). The Althen test requires the petitioner to set forth: “(1) a medical theory causally
connecting the vaccination and the injury; (2) a logical sequence of cause and effect showing that
the vaccination was the reason for the injury; and (3) a showing of a proximate temporal
relationship between vaccination and injury.” Id. To establish entitlement to compensation
under the Program, Petitioner is required to establish each of the three prongs of Althen by a
preponderance of the evidence. See id.

        Specifically, under the first prong of Althen, Petitioner must offer a scientific or medical
theory that answers in the affirmative the question “can [the] vaccine(s) at issue cause the type of
injury alleged?” See Pafford v. Sec’y of Health & Human Servs., No. 01-0165V, 2004 WL
1717359, at *16 (Fed. Cl. Spec. Mstr. July 16, 2004). This may be accomplished in a number of
ways. “Reliability and plausibility of [] pathogenesis can be bolstered by providing evidence

                                                 49
that at least a sufficient minority in the medical community has accepted the theory, so as to
render it credible.” Id. at *16-17. In addition, “epidemiological studies and an expert’s
experience are not dispositive, but lend credence to a claim of plausibility.” Id. at *17. Medical
literature published in respected medical journals is also persuasive. Id. “However, publication
‘does not necessarily correlate with reliability,’ because ‘in some instances well-grounded but
innovative theories will not have been published.’” Id. (quoting Daubert v. Merrell Dow
Pharm., Inc., 509 U.S. 579, 593-94 (1993)).

        In addition to showing that the vaccine at issue can cause a particular injury, a petitioner
must also, under Althen’s second prong, prove that the vaccine actually did cause the alleged
injury in a particular case. See Pafford, 2004 WL 1717359 at *16; Althen, 418 F.3d at 1279. A
petitioner does not meet this obligation by showing only a temporal association between the
vaccination and the injury; the petitioner must explain “how and why the injury occurred.”
Pafford, 2004 WL 1717359 at *16.

        Although a temporal association alone is insufficient to establish causation, under the
third prong of Althen, a petitioner must show that the timing of the injury fits with the causal
theory. See Althen, 418 F.3d at 1278. The special master cannot infer causation from temporal
proximity alone. See Thibaudeau v. Sec’y of Health & Human Servs., 24 Cl. Ct. 400, 403-04
(Fed. Cl. Oct. 23, 1991); see also Grant v. Sec’y of Health & Human Servs., 956 F.2d 1144, 1148
(Fed. Cir. 1992) (“The inoculation is not the cause of every event that occurs within the ten[-]day
period . . . . Without more, this proximate temporal relationship will not support a finding of
causation.” (quoting Hasler v. United States, 718 F.2d 202, 205 (6th Cir. 1983))).

         A petitioner who demonstrates by a preponderance of the evidence that he or she
suffered an injury caused by vaccination is entitled to compensation, unless Respondent can
demonstrate by a preponderance of the evidence that the injury was caused by factors unrelated
to the vaccination. See Althen, 418 F.3d at 1278; Paluck v. Sec’y of Health & Human Servs., 786
F.3d 1373, 1386 (Fed. Cir. 2015) (citing de Bazan v. Sec’y of Health & Human Servs., 539 F.3d
1347, 1352 (Fed. Cir. 2008) (holding that it is not a petitioner’s burden “to rule out every other
potential cause of his injury”); Knudsen v. Sec’y of Health & Human Servs., 35 F.3d 543, 547
(Fed. Cir. 1994).

        VI.    Discussion21

                   a. Diagnosis

        Petitioner’s causation theory begins with a diagnosis of narcolepsy type one with
cataplexy. Petitioner’s treating physician described her symptoms as consistent with narcolepsy,

21
  The undersigned has reviewed all of the medical literature provided by the parties, but will
only discuss the literature relevant to this decision. See Moriarty v. Sec’y of Health & Human
Servs., 844 F.3d 1322, 1328 (Fed. Cir. 2016) (“We generally presume that a special master
considered the relevant record evidence even though [she] does not explicitly reference such
evidence in [her] decision.”) (citation omitted).

                                                 50
as well as sleep apnea, side effects from medication, stress and anxiety, and/or seizures. See
generally Pet’r’s Exs. 2, 4. Petitioner’s expert, Dr. Kinsbourne, conceded that he does not have
the formalized training or clinical experience to diagnose sleep disorders generally or narcolepsy
specifically. Tr. at 212. He then acknowledged that he relied on the results from the sleep tests
as the basis for the diagnosis underlying his causation theory. Id. At the time of Petitioner’s
testing, she was taking several medications that can significantly alter sleep patterns, cause
drowsiness, and insomnia; including, but not limited to, hydrocodone, lorazepam, and
topiramate. See id. Petitioner’s test results, while within the range consistent with narcolepsy,
are less persuasive given all of the other factors that could have materially affected the integrity
of the tests. Additionally Dr. Kinsbourne’s admitted lack of clinical experience with narcolepsy
undercuts his opinion as probative evidence with regard to Petitioner’s diagnosis.

         Alternatively, Respondent’s expert Dr. Scammell noted that he currently treats patients
for sleep disorders, including narcolepsy. Tr. at 244-46. Both in his written expert reports and
testimony, Dr. Scammell questioned the accuracy of Petitioner’s diagnosis through a discussion
of Petitioner’s symptoms and a comparison to what a clinician would see in a common
narcolepsy with cataplexy case. Id. at 254-59. The sleep tests were particularly troublesome for
Dr. Scammell, because of the lack of precision and control exerted by the administrators. Id. at
267-69. Petitioner was not taken off of the medications that could negatively impact her ability
to stay and fall asleep or awaken. The record revealed that Petitioner was unable to get the ideal
number of sleep hours in the nights immediately prior to the test, or during the polysomnogram.
Id. at 267. Dr. Scammell also noted that additional testing and treatment for Petitioner’s sleep
apnea could have better established Petitioner’s baseline for comparison to her testing for
narcolepsy. Id. at 263-64. Although Dr. Scammell was not convinced that Petitioner suffered
from narcolepsy, ultimately he could not say it was more likely than not that Petitioner did not
have narcolepsy. Id. at 275.

          Accordingly, the evidence supports by a preponderant standard that Petitioner did meet
the minimum requirements for a narcolepsy diagnosis based on her polysomnogram and MSLT.
Her cataplexy symptoms, however, were more dubious. Dr. Scammell described typical
cataplexy episodes as brief and emotion-triggered. Id. at 255. He went on to describe how the
facial muscles relax, the eyes are rarely open, and other common characteristics of cataplexy
episodes. Id. at 257. Once the episode is over, Dr. Scammell noted that the person suffering
from the episode quickly returns to normal. Id. The witness testimony describing Petitioner’s
cataplexy episodes were inconsistent with each other and Dr. Scammell’s description.
Additionally, there were only a few incidents of emotional triggers for Petitioner’s episodes.
Petitioner was often reduced to a catatonic state for several minutes or hours with her eyes wide
open in a fixed, blank stare. Id. After Petitioner regained consciousness and muscle control, she
was often upset and inconsolable for an additional period of time. Id. at 258-59. Dr. Scammell
noted that Petitioner’s description of her episodes were extremely unusual, but he would not rule
out narcolepsy with cataplexy and neither will I. Based off the polysomnogram and MSLT
results, the symptoms insofar as they are consistent with narcolepsy, the therapeutic effects of
treatments used for narcolepsy, the presence of the HLA-DQB1*0602 genetic marker common
in those with narcolepsy, and the expert opinions, Petitioner has established that she more likely
than not suffered from narcolepsy with cataplexy.

                                                 51
                   b. Althen Prong One

Petitioner’s Theory

        Petitioner’s contends that narcolepsy sometimes develops following a flu vaccination
because the body produces antibodies in response to the vaccine, and those antibodies cross-react
(improperly) with hypocretin receptors and damage them. Pet’r’s Ex. 16 at 2-5. These receptors
are then unable to properly regulate the excitation feedback necessary for the brain to awaken
and stay awake, and narcolepsy is the result. Id. at 4. This theory, based on molecular mimicry,
has been asserted previously in the Program. See D’Tiole v. Sec’y of Health & Human Servs.,
No. 15-085V, 2016 WL 7664475 (Fed. Cl. Spec. Mstr. Nov. 28, 2016), mot. for review denied,
123 Fed.Cl. 421 (2017), aff’d, No. 2017-1982, 2018 WL 1750619 (Fed. Cir. 2018) (finding
petitioner failed to establish a reliable causation theory). It is unsuccessful here as it has been
previously, for many of the same reasons. Petitioner’s theory analogizes two very different flu
vaccines, Pandemrix to Fluzone, in an attempt to illustrate a cross-reaction between the immune
system and an unknown protein within Fluzone. These vaccines are not analogous, however,
because they differ in manufacturing, viral strains, and the presence of an adjuvant. Pandemrix
is an adjuvanted, influenza vaccine that was administered in Europe in 2009 to combat an H1N1
pandemic. See Resp’t’s Ex. C at 9. Fluzone is a non-adjuvanted trivalent vaccine currently used
in the United States and at issue here. One cannot be substituted for the other in a simple cut and
paste to establish a causality that contradicts epidemiological findings.

Other Narcolepsy Cases in the Program

         A comparison between this case and two recent flu-narcolepsy decisions will help
illustrate Petitioner’s failure to meet her burden under Althen. D’Tiole was the first of two cases
wherein Special Master Corcoran considered whether a flu vaccine could cause narcolepsy with
cataplexy. D’Tiole, 2016 WL 7664475 (Fed. Cl. Spec. Mstr. Nov. 28, 2016). In D’Tiole, the
petitioner received the FluMist vaccine, a live attenuated flu vaccine, on December 13, 2011. Id.
at *1. The petitioner’s narcolepsy symptoms did not arise for several months, and he was
ultimately diagnosed with narcolepsy with cataplexy in August of 2013. Id. at *3. This
diagnosis was confirmed in 2014, and testing revealed that the petitioner possessed the HLA
gene associated with narcolepsy. Id.

        The petitioner’s expert, Dr. Steinman, argued that the petitioner’s narcolepsy was caused
by an autoimmune reaction brought about through molecular mimicry between nucleoprotein
found in the flu vaccine and hypocretin receptors. Id. Dr. Steinman referred to the Pandemrix
studies to support his theory with respect to FluMist. Id. at *5.

        Respondent put forward two experts, Dr. Michael Kohrman and Dr. Andrew
MacGinnitie. Id. at *10, *11. Dr. Kohrman argued that there is no evidence that a live H1N1-
containing flu vaccine is associated with narcolepsy and relied upon the Duffy study as support
of his argument. Id. at *10. Dr. Kohrman found this result as evidence that whatever caused
Pandemrix to be associated with narcolepsy was unique in its manufacturing, and therefore its
connection is non-transferrable to vaccines not produced in a similar way. Id.

                                                52
        Dr. Andrew MacGinnitie primarily focused on how the flu vaccine administered in the
case differs from Pandemrix. Id. at *11. Dr. MacGinnitie also cited Duffy as evidence against a
connection between unadjuvanted vaccines and narcolepsy. Id. at *12. Dr. MacGinnitie
concluded that the petitioner in fact received a vaccine that was “functionally the same” as the
one studied in Duffy, further evidence against the petitioner’s causation theory. Id. at *13.

        In response, Dr. Steinman attacked the Duffy study much in the same way Dr.
Kinsbourne did in the present case. Id. at *7. Special Master Corcoran then explained that,
although petitioners are not expected or required to produce epidemiological studies to prove
their theory, “this does not mean that epidemiological evidence relevant to a vaccine at issue in a
case has no place in evaluating a claim – especially when the evidence is particularly on point
and persuasive.” Id. The petitioner “unconvincingly quibble[d] with aspects of Duffy,” wrote
Special Master Corcoran. Id.

        Special Master Corcoran did not find reliable the petitioner’s attempt to apply the
evidence surrounding Pandemrix to FluMist, a completely different formulation of the flu
vaccine.22 “[The] [p]etitioner has, in effect, attempted to leverage a theory that is reliable with
respect to one form of the flu vaccine into a case involving a different form, but without showing
that the theory is similarly reliable in the different setting.” Id. at *20. Special Master Corcoran
ultimately dismissed the petitioner’s claim. Id. at *28.

       In McCollum, Special Master Corcoran was again asked to determine whether a flu
vaccine could cause narcolepsy. McCollum v. Sec’y of Health & Human Servs., No. 14-790V,
2017 WL 5386613 (Fed. Cl. Spec. Mstr. Sept. 15, 2017), motion for reconsideration denied, 135
Fed. Cl. 735 (2018), appeal docketed, No. 18-1623 (Fed. Cir. Feb. 28, 2018). The petitioner’s
medical history was replete with a host of pre-existing health conditions, including OSA,
smoking, ADHD, obesity, type II diabetes, severe hypertension, and chronic back pain. Id. at *1.
The petitioner reportedly received his flu vaccine on September 24, 2011, and his medical
records do not show any narcoleptic symptoms until February 2, 2012. Id. at *3. In March of
2012, the petitioner’s physician diagnosed him with narcolepsy with “near cataplexy.” Id.

         The petitioner called one expert in McCullom, Dr. Marcel Kinsbourne. Id. at *6. Dr.
Kinsbourne put forward the same causation theory as the one argued in the current case. In
summarizing the petitioner’s theory, Special Master Corcoran noted that “[t]here is an immediate
facial limitation . . . to the application of such literature in this case,” because Pandemrix was
never used in the United States. Id. at *8. Special Master Corcoran wrote that the petitioner
attempted to get around this issue by arguing that the wild-type virus can cause narcolepsy and
by claiming that Pandemrix has comparable nucleoprotein levels as vaccines used in the United
States. Id. Dr. Kinsbourne also addressed the Duffy study the same way as he does in the case
at hand. Id.

22
  Special Master Corcoran further made legal findings regarding why the Court did not need a
hearing in D’Tiole. 2016 WL 7664475 at *25-28. Because these findings are irrelevant to the
undersigned’s analysis, they are omitted.

                                                53
        Special Master Corcoran wrote, “[a]ll of [the petitioner’s causation theory] must be
evaluated in a context in which Duffy, the sole relevant epidemiologic evidence regarding the
impact of the version of the H1N1 flu vaccine administered in the U.S., contradicts [the
petitioner’s] contentions about a causal link.” Id. at *17. Although epidemiological studies are
not required of petitioners in the Vaccine Program, Special Master Corcoran credited Duffy as
“highly persuasive” and summarized his past findings of the study as reliable. Id. “[I]t is not
enough to respond by arguing [as Dr. Kinsbourne proposed in that case and the present case] that
the rare nature of a vaccine injury renders all epidemiologic evidence effectively useless.” Id.
Special Master Corcoran concluded by stating that although the petitioner’s theory does not meet
Althen prong one, it “remains intriguing despite [his] determination.” Id. at *19. The
petitioner’s claim was accordingly dismissed. Id. at *23.

        In both of these cases, Special Master Corcoran outlined why the application of the
science pertaining to the development of narcolepsy following an adjuvanted flu vaccine does
not translate to an unadjuvanted vaccine alleged to cause narcolepsy with cataplexy. D’Tiole,
2016 WL 7664475 at *20-28; McCullom, 2017 WL 5386613 at *17-19. These cases are
apposite to the case at hand, and ultimately Petitioner, like the petitioners in D’Tiole and
McCullom, failed to meet her burden.

       In D’Tiole, Respondent put forward Dr. MacGinnitie as an expert. 2016 WL 766475 at
*10-13. MacGinnitie is the same expert used by Respondent in this case, and in that case as he
did here, he opined that the flu vaccine administered to the petitioner is sufficiently different
from Pandemrix to make the comparison unpersuasive. Id. at *11. He also effectively explained
why the Duffy study is strong evidence against the petitioner’s theory. Id. at *12. Dr.
MacGinnitie is qualified to opine on vaccine injuries and narcolepsy and that is apparent in his
testimony and written reports.

        McCullom is also illustrative in comparison to this case. Both the petitioner in McCullom
and Petitioner in this case suffered from other sleep-related conditions that made the diagnosis an
issue that required in-depth, expert analysis. 2017 WL 5386613 at *1. Most importantly, the
petitioner in McCullom put forward the same expert with the same causation theory. Id. at *6.
Special Master Corcoran ultimately found that the petitioner’s theory cannot overcome the
evidence presented in Duffy, and consequently, the petitioner did not meet his burden in the face
of compelling medical literature that conflicts with his theory. Id. at *17-19. Despite
Petitioner’s request to have more time to address the Duffy study in this case and the potentially
damaging arguments against Dr. Kinsbourne’s theory that it presents, Petitioner was
unsuccessful in presenting a theory that meets the preponderant standard.

Medical Literature Provides Probative Evidence that Undercuts Petitioner’s Theory

        Petitioner’s expert, Dr. Kinsbourne, discussed an unidentified influenza protein that he
suggested is present in both vaccines and cross-reacts with “the same protein in the receptor for
the hypocretin.” Tr. at 182-83. This theory is an overbroad extension of the widely accepted
theory that a relationship exists between Pandemrix and narcolepsy. Epidemiologist have tried,
without success, to identify similar relationships between narcolepsy and other influenza
vaccines, including Fluzone. Some studies have focused on adjuvanted vaccines to determine if

                                                54
the presence of an adjuvant is a necessary condition to establish a causal link between a flu
vaccine and a subsequent narcolepsy diagnosis. See Pet’r’s Ex. 19 at 9, Yves Dauvilliers et al.,
Increased Risk of Narcolepsy in Children and Adults after Pandemic H1N1 Vaccination in
France, 136 Brain 2486, 2494 (2013) (“The mechanisms underlying such an association
[between Pandemrix and narcolepsy] remain unclear . . . .”); Pet’r’s Ex. 33 at 5-8, Jacques
Montplaisir et al., Risk of Narcolepsy Associated with Inactivated Adjuvanted (AS03) A/H1N1
(2009) Pandemic Influenza Vaccine in Quebec, 9 PLoS ONE 1, 5-8 (2014) (discussing
narcolepsy rate and risk of narcolepsy); see also Pet’r’s Ex. 52F at 2, S. Sohail Ahmed, MD et
al., The Safety of Adjuvanted Vaccines Revisited: Vaccine-Induced Narcolepsy, 18 Isr. Med.
Ass’n J. 216, 217 (2016) (finding that previous research “support[s] the concept that vaccine-
associated narcolepsy is not due solely to the characteristics of the adjuvant”). Dr. Kinsbourne
mentioned those studies during his testimony and counts himself among those that do not believe
that the adjuvant within any given vaccine is the cause or significant contributing factor to the
development of narcolepsy. Tr. at 186-87. Specifically, he discussed studies of two other
adjuvanted vaccines, Arepanrix and Focetria, and noted that the medical literature does not
reflect as significant an increase in the incidence of narcolepsy in individuals following these
vaccinations as with Pandemrix. Id. at 187-88.

        Other studies have focused on non-adjuvanted vaccines (like the one Petitioner received)
and concluded that there does not appear to be any relationship between these vaccines and
narcolepsy. See Duffy. Despite these results that appear to be more conclusive than the studies
Dr. Kinsbourne relies on to discount the possible role of adjuvants, Dr. Kinsbourne opined that a
nucleoprotein within the vaccine Fluzone is the causal agent for the development of narcolepsy.
Tr. at 182-83. Dr. Kinsbourne did not identify the specific protein, but stated the protein is
present in the Fluzone vaccine, the Pandemrix vaccine, and also the wild H1N1 influenza virus.23
Id. at 183-85, 188-89. He also did not provide any evidence to support his premise that this
particular protein is found in both vaccines and the wild virus. Dr. Kinsbourne did discuss a
study that found an increase in narcolepsy following an H1N1 epidemic in China. Id. at 189.
The cases in China were not related to vaccination, but Dr. Kinsbourne asserted that the
nucleoprotein in the H1N1 wild virus that likely triggered the increase in narcolepsy is also
present in Fluzone. See Pet’r’s Ex. 16 at 4-5. This study did not identify the relevant protein,
but Dr. Kinsbourne reasoned that the H1N1 protein is so similar to the neuropeptide hypocretin
that cross-reaction occurs once the immune system is triggered by the vaccine. Id. at 4-5.
Consequently, the body begins to destroy the hypocretin neurons in addition to the H1N1
proteins. Id. at 3-5.

23
  Medical literature, epidemiological studies, general acceptance of an asserted medical theory,
nor demonstration of a specific mechanism are requirements to satisfy a petitioner’s burden
pursuant to the first prong of Althen. Andreu v. Sec’y of Health & Human Servs., 569 F.3d 1367,
1378-79 (Fed. Cir. 2009) (citing Capizzano, 440 F.3d at 1325-26). Accordingly, special masters
must take care not to increase the burden placed on petitioners that are offering a scientific
theory linking vaccine to injury. Ultimately, petitioners must prove their cases by satisfying a
preponderance of the evidence burden of proof that is applied to every aspect of their claim,
including the reliable and plausible causal theory pursuant to Althen’s first prong.

                                               55
        Dr. Kinsbourne relied on the De la Herrán-Arita study in support of his theory, but
ultimately conceded that the study had been retracted due to fraudulent results prior to the filing
of Petitioner’s initial expert report. See De la Herrán-Arita; Tr. at 214. Additionally, both of
Respondent’s experts effectively explained why the ‘results’ in the De la Herrán- Arita study are
not probative here. Dr. Scammell admitted that he originally thought it “probable that an
immune stimulus such as influenza . . . triggers a T[]cell response and that in genetically
susceptible persons [with the HLA-DBQ1*0602 gene] this inflammatory reaction damages the
orexin-producing neurons . . . .” Id. at 278. Dr. Scammell stated that he ultimately discounted
this hypothesis when presented with “the facts that no signs of inflammation are detected in . . .
cerebrospinal fluid or seen on magnetic resonance imaging,” in these narcoleptic patients. Id.
He also noted that treatments designed to target immune system malfunctions, “like steroids . . .
have not been helpful” to treat these cases. Id.

        Dr. MacGinnitie also discussed his initial belief in this theory, which he stated sought to
confirm that in genetically susceptible narcoleptics “T[]cells were present and they were directed
against hypocretin[,] [thereby providing]… a great explanation” for the autoimmune
pathogenesis of narcolepsy. Id. at 302-03. Dr. MacGinnitie explained the peptide-specific
nature of a T cell response compared to the more generalized role of B cell antibodies. Id. Dr.
MacGinnitie then noted that the Ahmed study produced findings opposite to De La Herrán-Arita
and, “shows antibodies, which are not so specific[;] it has no evidence for T cells, and the
antibodies are directing it against an antigen that probably can’t be the cause of the disease
because otherwise it would cause such widespread neurological problems.” Ahmed (2015); Tr. at
304.

         Dr. Kinsbourne was asked if the Herrán-Arita study “is still a reliable piece of scientific
evidence,” and he replied, “[n]o . . . [b]ut it still seemed to me, overwhelmingly likely . . . [,]
even though we don’t know the homology that’s involved.” Tr. at 215. He went on to note,
“[i]t’s the same theory, whether it’s based on the article or not.” Id. Dr. Kinsbourne ultimately
concluded that the Herrán-Arita article’s theory was correct even though the results could not be
replicated, and stated, “[the retraction] doesn’t change my opinion.” Id. at 216.

The Role the Immune System Plays under Petitioner’s Theory Does Not Withstand Scrutiny

        Respondent’s experts enumerated three problems with Petitioner’s reliance on this theory
in addition to the article’s retraction. Resp’t’s Ex. A at 11; Resp’t’s Ex. C at 3-4, 6-7. After a
full consideration of the evidence, Petitioner is unable to adequately respond to the critiques her
causation theory welcomes. Therefore, it cannot survive under the preponderance standard.
First, Dr. Scammell noted that Dr. Kinsbourne pointed to the autoimmune system’s destruction
of hypocretin receptors as the cause of vaccine-induced narcolepsy. Dr. Scammell countered
that there is no explanation as to how or why the antibodies produced in response to the vaccine
only damage these receptors if they are located in this limited region on the brain, despite their
widespread presence in other regions. Tr. at 281. Dr. MacGinnitie agreed, testifying that “this
idea that antibodies against the hypocretin-2 receptor would be causative [i]s problematic
because the receptor is so widely distributed.” Tr. at 297.

                                                 56
        Dr. MacGinnitie also pointed out that “the fact that antibodies against hypocretin receptor
exists, could be a marker of the disease, rather than the cause of the disease.” Id. at 300. Dr.
MacGinnitie further explained this, stating that “as an autoimmune attack occurs and the cells
that are being attacked die, they release other proteins that often are not exposed to the immune
system, and then you can actually see antibodies against them that aren’t causative of the disease
but are just a marker of it.” Id. Dr. Kinsbourne was unable to explain why his proposed immune
response was so localized, or counter Dr. MacGinnitie’s statement that the antibodies could just
as easily be catalysts as markers. His continued reliance on the largely unknown state of
vaccine-induced injuries is particularly weak in this case, where so much research has been done
to understand the relationship between flu vaccines and narcolepsy.

         Finally, Dr. MacGinnitie noted that the there are no studies that apply the type of causal
relationship seen with the adjuvanted Pandemrix to a non-adjuvanted vaccine like Fluzone. Id. at
297-98. “The simplest [possibility] is that it’s something about the adjuvant that actually
triggered the narcolepsy.” Id. at 298. Dr. MacGinnitie clarified that it is not clear if the adjuvant
is sufficient to cause narcolepsy, but he does believe that it is clear that the adjuvant is necessary.
Id. at 310.

        Dr. MacGinnitie concluded his testimony by discussing several epidemiological studies
that support his conclusion that there is no relationship between nonadjuvanted vaccines and
narcolepsy. Id. at 314-22. Dr. MacGinnitie acknowledged that vaccines can cause injury and
even went as far as to agree that “there is a potential autoimmune pathogenesis for narcolepsy.”
Id. at 323. Dr. MacGinnitie’s problem with Petitioner’s theory is specific to the causation
mechanism, “the idea that antibodies are generated against the hypocretin receptor” in response
to any flu vaccination or exposure to the H1N1 wild virus. Id.

        Petitioner does not present any convincing evidence to undercut the findings from the
Duffy study. Furthermore, Dr. Kinsbourne’s unofficial reliance on science offered in a retracted
study is not persuasive. The mechanism that Petitioner is relying on is vague and what little
specificity his expert does articulate runs contrary to documented epidemiology. Studies that
provide insight into rare medical events are often impossible to create. They are therefore not
necessary for a successful claim in the Program. However, when there are relevant studies such
as those that have been discussed by the experts in this case, they are valuable evidence to
support or rebut a vaccine’s role in the causation of an alleged medical condition. Dr.
Kinsbourne’s criticism of the Duffy study and further explanation of the De La Herrán-Arita
study does not provide sufficient corroboration for his causation theory. Petitioner fails to satisfy
his burden under prong one of Althen.

                   c. Althen Prong Two

        It is impossible to do any meaningful analysis for prong two without a developed theory
to apply to Petitioner’s circumstances. Furthermore, an attempt to apply the theory asserted by
Dr. Kinsbourne to Petitioner’s history reveals that there is no evidence in the record to explain
how Petitioner’s vaccination triggered an immune response that resulted in narcolepsy. There is
no evidence that supports an autoimmune reaction in Petitioner’s case. There was no attempt to
rule out autoimmune disease based on any of her symptoms. There was no evidence of

                                                  57
inflammation or an acute reaction at the time of the vaccination. See Pet’r’s Ex. 2 at 118, 237.
Petitioner was being treated for neck pain and migraine with hydrocodone. Id. Petitioner was
also prescribed Zoloft for anxiety, which can cause insomnia. Pfizer, Inc., Zoloft Medication
Guide 8 (2016), https://www.accessdata.fda.gov/scripts/cder/daf/index.cfm?event=overview.
process&ApplNo=020844; Pet’r’s Ex. 2 at 236-44. Dr. Kinsbourne made it clear during his
testimony that the theory he presented is “one way of explaining what happened to [Petitioner,]”
and that he is “not asserting that [his theory is] necessary [sic] the case” for her. Tr. at 232. He
cautioned that the theory “[is] not scientifically certain” but opined that it is more likely than not
what happened to Petitioner. Id. Unequivocally, Petitioner does not have to prove any aspect of
her causation theory with scientific certainty. The assurances of an expert without supporting
evidence, is not, however, enough to meet the preponderant standard in the face of relevant and
credible epidemiological studies, well-versed opposing experts, and Petitioner’s reliance on a
retracted article.

                   d. Althen Prong Three

        I will complete the Althen analysis and address the evidence of a temporal relationship
between the onset of Petitioner’s narcolepsy with cataplexy and the date of her vaccination.
Petitioner’s medical records and witness testimony describe Petitioner’s sixty-hour work weeks
and long stretches of work-related driving. Petitioner’s witnesses stated that she “was up very
early in the morning and gone, and then she would not come home until very late at night.” Tr.
at 18-19. Petitioner’s son described her as “busy with her job” and stated that she “worked three
times harder than she should have – she was always tired after a long day at work . . . .” Id. at
60. This is clear evidence in the record that Petitioner suffered from tiredness and fatigue prior
to her vaccination. There is also, however, witness testimony that approximately four to five
weeks following vaccination, Petitioner began to fall asleep driving and was unable to stay
awake without drinking multiple caffeinated drinks throughout the day or taking a nap. Tr. at
133-34, 136-37. Witnesses describe post-vaccination episodes of ‘cataplexy’ wherein Petitioner
would “go down” for ten minutes at a time or longer or stare “off into space but still looking at
the TV with no response” for several minutes. Id. at 28, 37-38. These episodes were
characterized by Dr. Scammell as “atypical” and “unusual[,] but” he ultimately conceded that
“everyone is different” and there is “a spectrum of [cataplexy] symptoms.” Id. at 275.

        Dr. Scammell noted that individuals with narcolepsy often have other sleep disorders
“[a]nd it’s possible that some of these factors or some combination of them is accounting for the
overall picture.” Id. at 260. Petitioner was also diagnosed with sleep apnea, another sleep
disorder similar to narcolepsy in symptoms, but she does not assert that the vaccine is
responsible for this condition. The similarities between the symptoms for sleep apnea and
narcolepsy, coupled with the unusual nature of Petitioner’s cataplexy episodes, make it difficult
to determine onset for Petitioner’s narcolepsy. However, Petitioner’s account of the
development of her narcolepsy was consistent with her medical records and Respondent’s
experts did not contest her timeline. Therefore, I find that the four week temporal relationship
between the development of Petitioner’s symptoms and the administration of the vaccine would
be appropriate based on what is known and widely accepted with respect to molecular mimicry
reactions to vaccination that result in injury. This temporal relationship, however, does not take
the place of a cogent causation theory necessary to meet the burden for prongs one and two. A

                                                  58
temporal relationship alone is insufficient to establish causation under prong three, and I find that
the one established here is of no consequence without a causation theory that explains the
development of Petitioner’s narcolepsy within the timeframe described.

        Dr. Kinsbourne relied largely on the timing between Petitioner’s vaccination and
diagnosis of narcolepsy to conclude a causal relationship. In his first expert report, Dr.
Kinsbourne’s conclusion began with the fact that Petitioner’s “narcolepsy became clinically
apparent within one month after vaccination.” Pet’r’s Ex. 12 at 10. Finding that Petitioner’s
condition developed “within a medically reasonable temporal interval of a trivalent influenza
vaccine,” and in the absence of “reliable evidence for any alternative cause,” Dr. Kinsbourne
opined that “the influenza vaccination did cause [Petitioner’s] narcolepsy.” Id. This conflation
of the factors necessary to show entitlement under Althen has been soundly rejected by the
program, including a prior flu vaccine - narcolepsy claim that asserted the same theory Dr.
Kinsbourne espouses here. See D’Tiole, 2016 WL 7664475; see, e.g., Moberly, 592 F.3d at
1323 (quoting Althen, 418 F.3d at 1278) (“[N]either a mere showing of a proximate temporal
relationship between vaccination and injury, nor a simplistic elimination of other potential causes
of the injury suffices, without more, to meet the burden of showing actual causation.”); Grant,
956 F.2d at 1148.

                   e. Alternative Cause

        Petitioner has not provided a causation theory that meets Petitioner’s burden of proof
under Althen prongs one and two. Respondent never offered an alternative cause to Petitioner’s
condition, and as the prima facie case has not been met, Respondent was never under obligation
to do so.

       VII.    Conclusion

        It is undeniable that Petitioner suffers from one or more sleep disorders that have
disrupted her way of life. However, Petitioner has failed to prove by a preponderance of the
evidence that she suffered from narcolepsy with cataplexy as a result of her Fluzone vaccination.
The causation theory presented by Petitioner is vague and incomplete, preventing any
meaningful application to the onset and character of Petitioner’s symptoms. Therefore, she is not
entitled to compensation under the Program.

       In the absence of a timely-filed motion for review filed pursuant to Vaccine Rule 23, the
Clerk of Court is directed to ENTER JUDGMENT consistent with this decision.

        IT IS SO ORDERED.
