                                               DECISION1

        This is an action in which Caylee Harrington (“Petitioner”) requests compensation under
the National Vaccine Injury Compensation Program (“the Program”).2 Petitioner alleges that she
suffers from multiple sclerosis (“MS”) as a result of receiving a second Human Papillomavirus
(“HPV” or “Gardasil”) vaccination on January 19, 2011. For the reasons set forth below, I
conclude that Petitioner is not entitled to compensation.

1
  Because this Decision contains a reasoned explanation for the action in this case, I intend to post this
Decision on the United States Court of Federal Claims’ website, in accordance with the E-Government Act
of 2002, Pub. L. No. 107-347, § 205, 116 Stat. 2899, 2913 (codified as amended at 44 U.S.C. § 3501 note
(2012)). In accordance with Vaccine Rule 18(b), a party has 14 days to identify and move to redact medical
or other information, that satisfies the criteria in 42 U.S.C. § 300aa-12(d)(4)(B). Further, consistent with
the rule, a motion for redaction must include a proposed redacted decision. If, upon review, I agree that the
identified material fits within the requirements of that provision, I will redact such material from public
access.

                                                       1
    I. PROCEDURAL HISTORY OF THIS CASE

       Petitioner filed her petition3 on January 17, 2014, alleging that her HPV vaccination of
January 19, 2011, caused her “systemic lupus erythematosus.” 4 Petition at ¶¶ 2, 8, ECF No. 1.
This case was initially assigned to Special Master Laura D. Millman. ECF No. 2. Petitioner filed
medical records on June 9, 2014 (Exhibits (Exs.) 2-22, see ECF No. 10), and June 24, 2014 (Exs.
23-24, see ECF No. 11).

        A. Case Development to Clarify Issue of Onset of Petitioner’s Symptoms

         Special Master Millman held a status conference on August 19, 2014, during which the
parties primarily discussed the onset of Petitioner’s symptoms in this case. See Order of August
29, 2014, ECF No. 14. Petitioner’s then-counsel5 stated that, according to Petitioner’s mother,
Petitioner “began experiencing symptoms, including fatigue, in late February 2011.” Id. Special
Master Millman, however, observed that the petition and the medical records filed to that date
indicated that Petitioner’s “symptoms began in April 2011.” Id. (citing Petition at ¶ 5; and
Petitioner’s medical records at Ex. 9 at 16). Accordingly, Special Master Millman, among other
things, ordered Petitioner and others familiar with the issue of onset of Petitioner’s symptoms to
file affidavits in this case. Id.

        Petitioner filed her affidavit (Ex. 27) on November 13, 2014, concurrently filing affidavits

3
  Caylee Harrington filed a separate, but substantially similar petition on March 14, 2014, which was
docketed as case number 14-212V, and assigned to Special Master Hamilton-Fieldman. Harrington v. Sec'y
of Health & Human Servs., No. 14-212V, 2014 WL 1813284 (Fed. Cl. Spec. Mstr. Apr. 16, 2014). On
April 16, 2014, Special Master Hamilton-Fieldman dismissed case number 14-212V, referencing Ms.
Harrington’s instant pending case as a basis for case number 14-212V violating the Vaccine Act’s
requirement that “[o]nly one petition may be filed with respect to each administration of a vaccine.” Id. at
*1 (citing § 300aa–11(b)(2) of the Vaccine Act).
4
 Petitioner originally filed her petition on January 17, 2014, alleging that her HPV vaccination of January
19, 2011, caused her “systemic lupus erythematosus.” Petition at 1-2, ¶¶ 2, 8, ECF No. 1. That petition
also states that, since her HPV vaccination of January 19, 2011, Petitioner “has been diagnosed with
systemic lupus erythematosus, Sj[ö]gren’s syndrome, transverse myelitis, complex migraines, and multiple
sclerosis.” Id. at 2, ¶7. Apart from her alleged systemic lupus erythematosus diagnosis, however, the
petition did not attribute any of her other conditions to the vaccination. See generally id. at 1-3. Although
Petitioner did not formally file an Amended Petition to change the specific injury she now alleges was
caused by her HPV vaccination of January 19, 2011, the six expert reports filed on her behalf by Lawrence
Steinman, M.D., exclusively claim that she suffers from MS due to her allegedly causal HPV vaccination.
See generally Exs. 35, 40, 42, 44, 46, 47. Petitioner’s Pre-Hearing Brief also explicitly acknowledges this
change in her alleged injury in this case, stating in the introduction of her Pre-Hearing Brief, “The
[P]etitioner, Caylee Harrington, submits this brief in support of her claim that the Gardasil vaccine she had
on January 19, 2011, caused her MS, definitively diagnosed in 2012.” Petitioner’s Pre-Hearing Brief at 1,
emphasis added, ECF No. 78 entitled “Petitioner’s Opening Brief.”
5
 Petitioner has had three counsel of record changes through the pendency of this case, with her current
counsel representing her since August 17, 2015. See ECF No. 35; see also Notice of 8/17/2015,
documenting Petitioner’s Consented Motion to Substitute Counsel for her current counsel of record.

                                                     2
from her mother, Catherine Harrington (Ex. 28), and her boyfriend, Michael Collier (Ex. 29). See
ECF No. 20. On December 22, 2014, Petitioner filed affidavits from her treating family nurse
practitioner, Teressa Becker, Family Nurse Practitioner (FNP) (Ex. 30), and treating counselor,
Julie Nicholson, Licensed Professional Counselor (LPC) (Ex. 31). See ECF No. 22. Petitioner
subsequently filed a statement of completion on January 21, 2015, indicating the record of this
case was complete. ECF No. 23.

        Special Master Millman held a status conference on February 4, 2015, to once again discuss
the issue of onset. See Order of February 4, 2015, ECF No. 24. She reiterated that the medical
records filed up to that point indicated an onset timeframe of April 2011. Id. Thus, she ordered
Petitioner to file a status report “listing citations to any medical records that are dated between
January 19, 2011 and October 30, 2012.” Id. The parties additionally discussed the revelation that
Petitioner also filed an affidavit in a related Vaccine Act case -- case number 14-212V6 -- in which
she averred that the onset of her symptoms began in March 2011, whereas her affidavit filed in
this case (Ex. 27) stated that her onset was in February 2011. Id. Accordingly, Respondent
requested leave to file Petitioner’s affidavit from case number 14-212V -- a request Special Master
Millman granted.

        On February 5, 2015, Respondent filed a document entitled “Respondent’s Status Report
And Notice Of Filing” (hereafter “Respondent’s Status Report of February 5, 2015”) in which
Respondent stated that “the medical records indicate an onset of [P]etitioner’s symptoms
beginning in about mid-April 2011.”7 See Respondent’s Status Report of February 5, 2015 at 1.
Moreover, that status report highlighted the discrepancy between Petitioner’s affidavit in this case
-- indicating that her symptoms started in “early February 2011” (id., citing Ex. 27 at 1) -- with an
affidavit filed in case number 14-212V, in which Petitioner stated that her symptoms developed
after mid-March 2011 (id. at 2). Respondent concurrently filed the affidavit from case number 14-
212V as Ex. A. See Id. at 2; see also Ex. A (“Affidavit of Petitioner, dated March 13, 2014”), ECF
No. 25-1.

        In compliance with Special Master Millman’s Order of February 4, 2015, Petitioner filed
a status report on February 24, 2015, listing citations of all the medical records that are dated
between January 19, 2011 and October 30, 2012.8 See Petitioner’s Status Report of February 24,
2015, ECF No. 26. On March 6, 2015, Petitioner filed a letter from her primary care doctor, Rachel

6
    See footnote 3, supra, for a detailed discussion of case number 14-212V.

7
  In support of his assertion, Respondent highlighted several of Petitioner’s medical records reflecting
Petitioner’s contemporaneous complaints to her treating physicians of her symptoms starting in mid-April
2011. See Respondent’s Status Report of February 5, 2015 at 1 (citing: Ex. 3 at 1-3, 13-21; Ex. 2 at 20; Ex.
5 at 57; and Ex. 9 at 16).
8
 That status report listed the following medical records as being dated between January 19, 2011 and
October 30, 2012: Ex. 2 at 5-35; Ex. 3 at 1-33; Ex. 4 at 1-13; Ex. 5 at 1-60; Ex. 6 at 1-12; Ex. 7 at 1-33;
Ex. 8 at 15-70; Ex. 9 at 16-20; Ex. 10 at 1-6; Ex. 11 at 1-12; Ex. 12 at 1-6; Ex. 13 at 1-31; Ex. 14 at 1-7;
Ex. 15 at 18-28, 30-56; Ex. 16 at 5-43; Ex. 17 at 1-3; Ex. 22 at 1-8. See Petitioner’s Status Report of
February 24, 2015 at 1-2, ECF No. 26.

                                                      3
Sy, D.O., in which Dr. Sy provides her opinion as to the onset and medical causation in this case.
See Ex. 32; ECF No. 27-1. Subsequently, Special Master Millman held a status conference on
March 9, 2015, during which Petitioner relayed her intentions to consult with an expert for the
purposes of procuring an expert report on her behalf. See Order of March 9, 2015.

        B. Case Development while Petitioner Attempted to Procure an Expert Report

        From March 2015 until March 2016, Petitioner attempted to procure an expert report in
this case. During that time, Petitioner filed additional medical records on March 19, 2015 (see Ex.
33, ECF No. 29), subsequently informing the Court on May 6, 2015, that she had retained a
neurologist, Darin Okuda, M.D., to review this case (see Order of May 6, 2015; see also Ex. 34,
ECF No. 30).

       On May 11, 2015, Respondent filed his Rule 4(c) Report, stating that “this case is not
appropriate for compensation under the terms of the Act” (see Rule 4(c) Report at 2, ECF No. 32),
and that the “petition must be dismissed” (id. at 12). Concurrent with his Rule 4(c) Report,
Respondent filed a recent medical research article (Ex. B,9 ECF No. 32-1), which, according to
Respondent, reflected that “there is no association between [the] HPV vaccine and demyelinating
conditions, including MS” (see Rule 4(c) Report at 11).

        From May 2015 until mid-November 2015, Petitioner requested, and was granted,
numerous extensions of time to file an expert report. See ECF Nos. 33-34, 36, 38-39; see also
non-PDF Orders of: 6/29/2015; 8/6/2015; 8/28/2015; 9/29/2015; and 11/2/2015. On November
18, 2015, Petitioner filed another motion for extension of time, indicating that she had recently
retained the services of Lawrence Steinman, M.D., to submit an expert report on her behalf. ECF
No. 41 at 1.

        C. Case Development through Expert Report Filings10

                1. Dr. Steinman’s First Expert Report

        Petitioner filed an expert report by Dr. Steinman on March 1, 2016 (“Steinman First Rep.”,
Ex. 35, ECF No. 43-1), concurrently filing the corresponding medical literature cited in that report

 Scheller NM, et al., Quadrivalent HPV Vaccination and Risk of Multiple Sclerosis and Other
Demyelinating Diseases of the Central Nervous System. JAMA. 2015; 313(1):54–61.
10
   In my discussion below, I attempt to elucidate the procedural history surrounding Petitioner’s filing of
six expert reports from Dr. Steinman. In so doing, I briefly discuss some of the orders filed by Special
Master Millman shortly after the submission of each of Dr. Steinman’s expert reports, in which she provides
her preliminary view of Dr. Steinman’s expert opinion. I note, however, that I have independently analyzed
the entire record of this case, and my analysis in the Analysis section, infra, was formulated after my own
close review of the medical records, and my own determinations regarding the persuasive value of the
expert reports and medical literature filed by both parties.

                                                    4
(Exs. 36-39,11 ECF Nos. 43-2 thru 43-5).

       In response, Special Master Millman issued an Order on March 7, 2016 (ECF No. 44),
highlighting the deficiencies she found in Dr. Steinman’s first expert report regarding the
appropriate temporal relationship between Petitioner’s second HPV vaccination and the onset of
her symptoms three months later (id. at 2-3). She encouraged Petitioner’s counsel to “seriously
consider making a motion to dismiss her case.” Id. at 3.

                 2. Dr. Steinman’s Second and Third Expert Reports

        On March 8, 2016, Petitioner filed Dr. Steinman’s second expert report, responding to
Special Master Millman’s concerns with his previous expert report. Ex. 40, ECF No. 45-1.
Petitioner also concurrently filed the corresponding medical literature cited in Dr. Steinman’s
second expert report. Ex. 41, ECF No. 45-2. Thereafter, Special Master Millman issued an Order
on March 9, 2016, criticizing Dr. Steinman’s interpretations of key medical literature cited in his
second expert report. ECF No. 46.

        In response, Petitioner filed Dr. Steinman’s third expert report on March 10, 2016 (Ex. 42,
ECF No. 47-1), concurrently filing the corresponding medical literature cited in his third expert
report (Ex. 43, ECF No. 47-2).

                 3. Respondent’s Expert Reports

         Respondent filed an expert report by a neurologist, Richard Tenser, M.D., on April 20,
2016 (Ex. C, ECF No. 49-1), concurrently filing his CV (Ex. D, ECF No. 49-2) and the medical
literature cited in his expert report (Exs. E-O, ECF Nos. 49-3 through 50-6). On that same date,
Respondent filed a status report informing the Court that he had also retained an immunologist to
provide an expert opinion in this case. ECF No. 51.

       Respondent filed an expert report by his immunologist, Harry Schroeder, M.D., Ph.D., on
June 27, 2016 (Ex. P, ECF No. 53-1), concurrently filing his CV (Ex. Q, ECF No. 53-2) and the
medical literature cited in his expert report (Exs. R-AA, ECF Nos. 53-3 through 54-6).

11
   For clarity of the record, I note that Ex. 36, entitled “Medical Literature Index,” is a list of the twenty-six
articles cited in Dr. Steinman’s first expert report. ECF No. 43-2. Petitioner’s counsel did not properly
file, as separate exhibits, the twenty-six articles listed in that Medical Literature Index. Instead, Petitioner’s
counsel filed the entirety of the twenty-six articles over three separate exhibits -- Ex. 37 (ECF No. 43-3),
Ex. 38 (ECF No. 43-4), and Ex. 39 (ECF No. 43-5) -- doing so without proper pagination. Thus, for ease
of reference, I will use the page numbers generated from the CM/ECF filing reflected at the top of the page.

        I additionally note that Petitioner’s counsel filed all of the corresponding medical literature that
was submitted with the five subsequent expert reports from Dr. Steinman in this same manner. Moreover,
some of the exhibits filed by Petitioner’s counsel in this case do not contain proper pagination. See Exs.
35-36, 40-44. Accordingly, I will use the same citing convention outlined above for all of those filings.

                                                        5
               4. Dr. Steinman’s Fourth through Sixth Expert Reports, and Respondent’s
                  Responsive Expert Reports

       Special Master Millman held a status conference on July 13, 2016, during which Petitioner
informed the Court of her wishes to file a rebuttal expert report from Dr. Steinman responding to
Respondent’s expert reports. ECF No. 55. Special Master Millman granted that request. Id.

        Petitioner filed Dr. Steinman’s fourth expert report on September 6, 2016 (Ex. 44, ECF
No. 56-1), primarily rebutting Dr. Schroeder’s expert report. On that same date, Special Master
Millman held a status conference to discuss Dr. Steinman’s fourth expert report. ECF No. 57.
During that status conference, Special Master Millman stated that Dr. Steinman’s fourth expert
report only rebutted the opinion of Dr. Schroeder, but did not rebut the opinion of Dr. Tenser. Id.
Petitioner thus requested additional time to file an expert report by Dr. Steinman rebutting the
opinion of Dr. Tenser. Id. In turn, Respondent also requested time to file an expert report by Dr.
Schroeder, responding to Dr. Steinman’s fourth expert report. Id. Special Master Millman granted
both of those requests. Id.

        Respondent filed a status report on September 7, 2016, noting that Dr. Steinman’s fourth
expert report references medical records that were not submitted into the record of this case, and
requesting that Petitioner file those records. ECF No. 58 at 1-2. Special Master Millman
subsequently ordered Petitioner to file those missing records. See non-PDF Order of 9/7/2016.

       On October 17, 2016, Petitioner filed the medical records ordered by Special Master
Millman (Ex. 45, ECF No. 59-1), and also filed Dr. Steinman’s fifth expert report rebutting the
opinion of Dr. Tenser (Ex. 46, ECF No. 59-2).

         On November 1, 2016, Respondent filed the supplemental expert report of Dr. Schroeder
(Ex. BB, ECF No. 60-1), and the corresponding medical literature cited in that expert report (Exs.
CC – DD; ECF Nos. 60-2 and 60-3). Subsequently, on November 28, 2016, Respondent filed the
supplemental expert report of Dr. Tenser (Ex. EE, ECF No. 61-1), and the corresponding medical
literature cited in that expert report (Exs. FF-GG; ECF Nos. 61-2 and 61-3).

        Special Master Millman held a status conference on February 15, 2017, during which she
ordered Petitioner to file Dr. Steinman’s sixth expert report that discussed “the timing of the onset
of [P]etitioner’s symptoms,” and that “provide[d] a basis for any conclusion [Dr. Steinman drew]
about causation.” ECF No. 62. On April 27, 2017, Petitioner filed Dr. Steinman’s sixth expert
report. ECF No. 64-1.

       D. Case Development since April 2017

       On May 15, 2017, Special Master Millman issued a Pre-Hearing Order scheduling a two-
day entitlement hearing for February 14 and 15, 2018, and setting filing deadlines for both parties.
ECF No. 65. Pursuant to that Pre-Hearing Order, Respondent submitted his pre-hearing

                                                 6
submissions on January 11, 2018, concurrently filing an exhibit list (ECF No. 68), a witness list
(ECF No. 69), and Respondent’s Pre-Hearing Brief (ECF No. 70).

        On January 16, 2018, Petitioner filed a motion for an enlargement of time, informing the
Court about the agreement of both parties to waive the hearing in this case, and requesting
additional time to file her pre-hearing submissions. ECF No. 71. Special Master Millman granted
that request on the same day. See non-PDF Order of 1/16/2018. Also on January 16, 2018, this
case was transferred from Special Master Millman to Chief Special Master Nora Beth Dorsey. See
Order of 1/16/2018, reassigning case to Chief Special Master Dorsey.

         Chief Special Master Dorsey held a status conference on January 17, 2018, during which
both parties confirmed that they agreed to waive the entitlement hearing in this case and requested
a ruling on the record. ECF No. 74. In turn, Chief Special Master Dorsey ordered that the parties
file a joint status report affirmatively stating in writing their intentions to waive their right to an
entitlement hearing. Id. Chief Special Master Dorsey also ordered the parties to file a joint pre-
hearing submission addressing any factual disputes and identifying “the issues that [the parties]
would like [Chief Special Master Dorsey] to address in her ruling.” Id. Moreover, she ordered
that, in the joint pre-hearing submission, the parties: “[S]hall also include a list of the dates and
exhibit numbers of petitioner’s MRI reports and shall confirm that all of petitioner’s MRI reports
have been filed.” ECF No. 74 at 1. Additionally, Chief Special Master Dorsey ordered that after
all of the parties’ responsive prehearing briefs were submitted, the record of this case will be
closed. Id. at 2.

      The parties filed a joint submission on January 19, 2018, affirmatively stating that they
waive a hearing in this case, and requesting that a determination regarding entitlement to
compensation be made based on the existing record. ECF No. 75. Additionally, that joint
submission stated the following:

       The parties have little dispute regarding the facts, as the medical records set forth
       petitioner’s relevant medical history. The parties agree that petitioner was
       diagnosed with multiple sclerosis (“MS”) in April 2012. The parties also agree that
       petitioner started having various non-specific symptoms in mid-April 2011.
       Petitioner’s expert, Dr. Lawrence Steinman, has opined that the onset of her MS
       was in mid-April 2011. Lay statements from petitioner, [her] mother and boyfriend
       relate that symptoms could have begun in February or March of 2011.

       Respondent’s experts (Dr. Richard Tenser and Dr. Harry Schroeder) disagree. The
       Chief Special Master will need to determine whether petitioner’s symptoms
       beginning in mid-April 2011 was [sic] the onset of her MS, which is the alleged
       vaccine injury stemming from her human papillomavirus (“HPV”) vaccine
       administered on January 19, 2011.

       The issues to be determined … are: (1) when was the onset of petitioner’s MS; and
       (2) has petitioner presented preponderant evidence of a vaccine-related injury based
       on Althen v. HHS, 418 F.3d 1274, 1278 (Fed. Cir. 2005).

                                                  7
ECF No. 75. Petitioner filed the CV of Dr. Steinman on January 22, 2018 (Ex. 48, ECF No. 76-
1), subsequently filing her pre-hearing submissions, including Petitioner’s Pre-Hearing Brief (ECF
No. 78)12 on January 26, 2018.

        The docket of this case reflects an informal electronic mail communication remark noted
by Chief Special Master Dorsey on January 30, 2018. See Informal e-mail communication remark
noted on 1/30/2018. That remark indicates that counsel for both parties e-mailed Chief Special
Master Dorsey’s law clerk informing the Court of their intentions not to submit any additional
responsive briefs, and indicating that both parties deem the record of this case to be closed as to
further evidence. Id.

        This case was reassigned to my docket on February 7, 2018. See Order of 2/7/2018. This
case is now ripe for a decision.

     II. FACTUAL BACKGROUND

        A.      Medical History Appearing in the Medical Records

                1. Petitioner’s Relevant Medical History prior to her HPV Vaccination of
                   January 16, 2011

       Petitioner’s pre-vaccination history reflects treatment for depression and a hospitalization
for complicated tonsillitis. See generally Exs. 23-26.

        Petitioner was admitted to the emergency department on January 16, 2011, for
psychological evaluation due to her “verbalizing suicidal ideation.” Ex. 26 at 1. She gave a history
at that time of having “premenstrual dysphoric disorder” that was being treated. Id. Upon
examination, her primary diagnosis was Depressive Disorder, “NOS” [Not Otherwise Specified],
and the follow-up care plan was for Petitioner to be admitted to inpatient psychiatric care. Id. at
2.

        On January 19, 2011, Petitioner presented to the Mountain Park Health Center for a
medication refill and to discuss hypoglycemia. Ex. 2 at 23. She relayed her recent history of going
to a “psych hospital,” stating that she was kept overnight for feelings of anxiousness and suicidal
thoughts. Id. Her physical examination was normal, but the remaining notations on that medical
record are illegible. Id. She received her second dose of the HPV vaccine at that time. 13 Ex. 1 at
1; Ex. 32.

  Petitioner’s counsel filed Petitioner’s Pre-Hearing Brief (entitled “Petitioner’s Opening Brief”) into the
record of this case two times -- once, as ECF No. 78, and again as ECF No. 79. Compare ECF Nos. 78 and
79.

  The HPV vaccine is generally administered as either a two-dose, or a three-dose series. See HPV Vaccine
Information for Clinicians at 4, found at: https://www.cdc.gov/hpv/hcp/need-to-know.pdf (last visited on
June 18, 2018). The records reflect that Petitioner received her first HPV vaccination on November 20,
2009. Ex. 25 at 4.

                                                     8
                2. Petitioner’s Relevant Medical History after her HPV Vaccination: January
                   16, 2011 through December 2011

       On February 24, 2011, Petitioner called her primary care doctor, Rachel Sy, D.O., with
complaints of inflamed glands, sore throat, and ear pain, requesting a referral to an Ear Nose and
Throat (“ENT”) specialist. Ex. 32 at 1.

        Petitioner was admitted to Tempe St. Luke’s Hospital’s emergency room on April 21,
2011, for “generalized weakness.” Ex. 3 at 13. The “History of Present Illness” section of that
record reflects Petitioner reported that she was feeling weird over the past week (i.e., since April
14, 2011), feeling “light headed and at times confused.” Id. She reported a history of
“hypoglycemia,” but relayed that she had not had a formal diagnosis by a physician, additionally
stating that she was having symptoms of low grade fevers, chills, and sore throat. Id. at 1, 13.
Her neurological exam at that time was benign (id. at 14), and her laboratory testing -- which
included a urinalysis, complete blood count (CBC), and basic metabolic panel (BMP) -- were all
within normal limits (id. at 13-21). Petitioner’s clinical impression was recorded to be “fatigue,”
and she was discharged with a recommendation to follow up with her primary care doctor. Id. at
15-16.

        Petitioner followed up with her primary care doctor, Dr. Sy, on April 22, 2011, at which
time she was evaluated as having a “distant affect.”14 Ex. 2 at 22. She was seen again by Dr. Sy
on April 25, 2011, at which time she provided a recent history of her symptoms, which included
neck stiffness, ear and jaw pain, and ear pressure. Id. at 21. Dr. Sy additionally noted that
Petitioner reported complaints of not being able to drive, not being able to hold a conversation,
fogginess of thoughts, numbness, and feeling cold. Id.

        Petitioner next visited Dr. Sy on May 2, 2011, at which time she reported having bilateral
pelvic pain for a “few weeks,” and having symptoms of “dizziness,” “blacking out,” and “throat
swelling” for the “past 3-4 wks.” Ex. 2 at 20. She additionally relayed a family history of lupus,
reporting that her aunt and grandmother suffered from that condition. Id. Petitioner again
consulted with Dr. Sy on May 4, 2011, reporting that she saw a neurologist who purportedly stated
that there was “nothing for him to do,” leading her to consult with a hematologist later that month.
Id. at 19. She reported having the same symptoms as in her recent prior visits, and requested an
ENT referral at that time. Id.

                a. Rheumatology Visits

        On May 17, 2011, Petitioner visited a rheumatologist, Stuart Posner, M.D., for further
evaluation of “a multiplicity of general medical and constitutional difficulties, chief among which
[was] the development of a pattern of fatigue, cognitive disturbance, and polyarthalgic joint pain.”
Ex. 4 at 7. That record reflects Petitioner’s recounting of her recent symptoms and family medical
history, and notations of Dr. Posner’s impressions of her recent laboratory testing. Id. at 7. In this
regard, Dr. Posner noted that Petitioner’s recent laboratory testing revealed “strongly positive”

14
  This medical record is partly illegible. I additionally note that Dr. Sy’s handwritten notations throughout
Ex. 2, reflecting her contemporaneous notations of Petitioner’s treatment visits, are difficult to read. See
Id. at 17-23.

                                                     9
ANA [antinuclear antibodies] and a positive rheumatoid factor15, which “provoked further
rheumatologic assessment,” especially in light of Petitioner’s maternal side of the family having a
history of lupus. Id. Upon examination, Dr. Posner’s clinical impression was that:

        Despite the reported positive rheumatoid factor and ANA, the patient does not
        exhibit currently pathognomonic or diagnostic features of active inflammatory
        connective tissue disease, i.e. she does not exhibit alterations on exam of chronic
        or acute inflammatory synovitis or vasculitis. The possibility that she may be in
        the process of evolving a connective tissue disease within the spectrum of an
        autoimmune process such as a lupus or lupus-variant disease cannot be completely
        excluded however. The issues of other causes for rheumatoid factor and ANA
        reactivity will have to be further assessed.

Ex. 4 at 7-8. Dr. Posner’s plan was to order additional laboratory studies, and to follow up with
Petitioner in a few weeks. Id. at 8.

        Petitioner had a subsequent visit with Dr. Posner on June 9, 2011, to relay the benign
findings of a spinal tap examination. Ex. 4 at 6. Additional testing since her last visit revealed
that her ESR16 was elevated, and that she had a positive RF, ANA titer, SS-A and SS-B, and Lyme
IgM factors.17 Id. Dr. Posner noted, among other things, that Petitioner “does not exhibit
diagnostic features of usual autoimmune disease associated with either lupus or rheumatoid

15
   Antibodies are immunoglobulin molecules (proteins) with a specific amino acid sequence. Dorland’s
Illustrated Medical Dictionary (32nd ed. 2012) at 100 (hereinafter “Dorland’s”). Antinuclear antibodies
(ANA) are a type of antibody directed against nuclear antigens, which are responsible for inducing specific
immune responses. Id. The immune system makes antibodies to fight infection, while ANAs attack the
body’s own tissues. ANA test, MAYO CLINIC, https://www.mayoclinic.org/tests-procedures/ana-
test/about/pac-20385204 (last visited July 3, 2018). Positive ANA tests indicate that the body has
mistakenly attacked its own tissue, with ANA testing often being used to confirm diagnoses of rheumatic
diseases. Id. Similarly, rheumatoid factors are proteins that the immune system produces that can also
mistakenly attack healthy tissues in the body.                  Rheumatoid Factors, MAYO CLINIC,
https://www.mayoclinic.org/tests-procedures/rheumatoid-factor/about/pac-20384800 (last visited July 3,
2018). Positive levels of the factor are most often associated with rheumatoid arthritis and Sjögren’s
syndrome. Id.
16
   Erythrocyte sedimentation rate (ESR) is another blood test that reveals the levels of inflammation in the
body. Sed rate (erythrocyte sedimentation rate), MAYO CLINIC, https://www.mayoclinic.org/tests
procedures/sed-rate/about/pac-20384797 (last visited July 3, 2018). ESR measures distance of blood cells
-- i.e., the greater the distance, the greater the inflammatory response. Id. Although her ESR was elevated
in June 2011, the lab testing from July to December 2011 indicated normal ESR levels. See Ex. 5; Ex. 15
at-1 at 18-29.
17
   When testing for ANA is positive (measured in titers), it is appropriate to test the presence of other
elevated antibodies common to rheumatic diseases. SS-A and SS-B Antibodies, IgG, Serum, MAYO CLINIC:
MAYO MEDICAL LABS, https://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive
/82403 (last visited July 3, 2018). These antibodies can include: RF, SS-A and SS-B (associated with
Sjögren’s syndrome), and IgM (immunoglobulin M is another infection-fighting antibody). Id.

arthritis.” Id. Dr. Posner outlined a treatment plan for Petitioner to seek an infectious disease
consult, and to be on a trial of low dose prednisone18 for symptom relief. Id.

       On July 8, 2011, Petitioner had a follow-up with Dr. Posner. At that time, Dr. Posner
recorded a summary of Petitioner’s recent medical history relating to her care by multiple
subspecialists; some of her treating doctors prescribed antibiotics for her suspected Lyme disease,
while others suspected a lupus-related disorder. Ex. 4 at 5.

                 b. Neurology Consults

        Petitioner consulted with a neurologist, George Wang, M.D., on June 10, 2011, for
complaints of headaches and passing out. Ex. 13 at 29. Petitioner reported that her “headache
started about 7 weeks ago.” Id. She also reported numbness in her extremities, visual disturbance
(seeing spots) and “body shaking”. Id. A neurological examination at that time was
unremarkable.19 Petitioner was assessed as having migraines20, and was prescribed Fioricet and
Topamax.21 Id. at 30-31.

        Petitioner continued to see Dr. Wang on several occasions over the next six months. See
visits with Dr. Wang on: July 1, 2011 (Ex. 13 at 26-28); August 12, 2011 (id. at 23-25); and
November 22, 2011 (id. at 20-22). Notably, on July 1, 2011, Petitioner relayed that she had some
new symptoms starting “about 3 weeks ago.” Id. at 26. She told Dr. Wang that her upper and
lower extremities had become weak, and that her weakness was getting to the point that she had
trouble getting around. Id. at 26-28.

18
  Prednisone is a synthetic glucocorticoid derived from corticoid, administered as an anti-inflammatory
and immunosuppressant. Dorland’s at 1509. It is often used to treat inflammation and works on the
immune system. Prednisone (Oral route), MAYO CLINIC, https://www.mayoclinic.org/drugs-
supplements/prednisone-oral-route/description/drg-20075269 (last visited July 3, 2018).
19
  That record also reflects that her cerebral spinal fluid (CSF) testing on May 18, 2011, was normal; and
that her laboratory testing on May 17, 2011, revealed positive ANA, and increased ESR. Ex. 13 at 29.

  “A migraine can cause severe throbbing pain or a pulsing sensation, usually on just one side of the head….
Aura may occur before or during migraines…. Auras are symptoms of the nervous system. They are usually
visual disturbances, such as flashes of light or wavy, zigzag vision. Sometimes auras can also be touching
sensations (sensory), movement (motor) or speech (verbal) disturbances. Your muscles may get weak, or
you may feel as though someone is touching you…. Examples of migraine aura include: Visual phenomena,
such as seeing various shapes, bright spots or flashes of light; vision loss; pins and needles sensations in an
arm or leg; weakness or numbness in the face or one side of the body; difficulty speaking; hearing noises
or music; and uncontrollable jerking or other movements.” See Migraine, Symptoms and Causes, MAYO

                c. Infectious Diseases Specialist

        Petitioner consulted with an infectious diseases specialist, Laura K. Schroeder,22 M.D., on
June 15, 2011. At that time, Petitioner reported that she “began experiencing very unusual
symptoms in the last few months,” including “some brain fog,” which progressed into joint pains,
in addition to neck and back pain. Ex. 5 at 57. She reported additional symptoms including:
ringing in the ears, “some hearing loss in the low ranges,” slight numbness of her hands, having
loss of motor function, and feeling “uncoordinated at times.” Id. Dr. Schroeder’s treatment plan
was that Petitioner had “extremely worrisome symptoms” that comprised “a cluster of unusual
neurologic findings, weight loss, staring spells and positive antibody for Lyme disease as well as
autoimmune markers.” Id. at 58.23 Additionally, Dr. Schroeder noted that “I cannot exclude that
Lyme disease alone is responsible for all of this, or whether or not this is a combination of Lyme
and lupus.” Id. Dr. Schroeder’s plan was to get further workup and prescribe intravenous Rocephin
therapy.24 Id.

        On August 12, 2011, Petitioner saw Dr. Schroeder again, at which time she noted that
Petitioner was enrolled in online classes due to her disability.25 Ex. 5 at 51. Dr. Schroeder’s
impression was that Petitioner continue her ongoing treatment for an autoimmune disorder with
prednisone, and treat her Lyme disease with doxycycline (an antibiotic). Id. Dr. Schroeder’s plan
was for Petitioner to continue her dosage of doxycycline for another month. Id.

        Petitioner was next examined by Dr. Schroeder on December 13, 2011, at which time
Petitioner was noted to be “doing well off of doxycycline with no systemic symptoms of [L]yme
disease at this time.” Ex. 5 at 50. Petitioner was additionally assessed with having a facial skin
lesion due to possible impetigo (a common, highly contagious bacterial skin infection), or HSV
(herpes simplex virus), and was prescribed Clindamycin (a common antibiotic) for her topical skin
lesions.26 Id.

22
   Dr. Laura K. Schroeder was Petitioner’s treating infectious diseases specialist; she has no relationship
with Dr. Harry Schroeder, Jr., an immunologist, who proffered an expert opinion on behalf of Respondent
in this case.
23
  That record also indicates the results of Petitioner’s laboratory testing performed throughout May 2011,
with Dr. Posner noting that Petitioner’s ESR was 33, and that she was “Sjogren’s positive,” “rheumatoid
factor positive,” “ANA titer 1:640,” and “Lyme disease IgM” positive. Additionally, her lumbar puncture
results were negative for elevated protein or glucose. Ex. 5 at 57.

25
   Dr. Schroeder wrote a letter for Petitioner’s college on July 27, 2011, noting that Petitioner was under
her care for a “devastating infection” and “severe autoimmune disease,” and requesting that Petitioner be
excused from her college classes. Ex. 5 at 53.
26
   Dr. Schroeder’s diagnoses at that time are listed as: “Lyme disease”; “Unspecified disorder of skin and
subcutaneous tissue”; “skin lesion”; and “systemic lupus erythematosus.” Ex. 5 at 50.

                                                    12
                 d. ENT Specialist

        Petitioner saw Timothy Kelsch, M.D., an ENT physician, on July 10, 2011. Ex. 12 at 3-5.
The “Assessment & Plan” section of that medical record reflects that Petitioner’s sensorineural
hearing loss and throat pain had improved from previous visits, and that she was “highly suspected
of [having] systemic lupus erythematosus.” Id. at 5. Dr. Kelsch noted that he was waiting for
further recommendations from her rheumatologist prior to assessing Petitioner’s treatment plan.
Id.

                 e. Laboratory Testing and Diagnostic Imaging

                             i. MRI Findings

       Petitioner underwent a brain magnetic resonance imaging (MRI), without contrast, 27 on
April 27, 2011, revealing a “mild cerebellar tonsillar ectopia” that was “suggestive of Chiari I
malformation.”28 Ex. 2 at 15-16. The MRI also showed a “mild right mastoid [an area behind the
middle ear] air space disease.” Id.

       Petitioner had a brain magnetic resonance angiography (MRA)29, without contrast,
performed on June 16, 2011. Ex. 13 at 13. The results from that testing were unremarkable. Id.

        Petitioner next had an MRI of the cervical spine, with and without contrast, performed on
July 8, 2011, which again revealed unremarkable results -- specifically, no abnormal enhancement
of the cervical spine. Ex. 13 at 5-6. On that same date, Petitioner also had a thoracic spine MRI,
with and without contrast. Ex. 2 at 31. That MRI revealed subtle hyperintensities from T7-T8

27
   Contrast material is used for MRIs of the brain and spinal cord to enhance the appearance of lesions
signifying disease in an active state. MRIs can be performed with injection into the blood of a contrasting
agent, such as gadolinium, which serves to increase (or “enhance”) the signal of certain types of lesions
visible to the radiologist performing the imaging. Active or newer lesions are more likely to enhance than
preexisting or older lesions because the contrasting agent is able to enter the brain via an existing breach in
the blood-brain barrier; once that barrier is repaired, and the contrast cannot reach the brain, lesions do not
appear enhanced. See W.C. v. Sec’y of Health & Human Servs., 100 Fed. Cl. 440, 444 (2011).
28
   A Chiari malformation is “a congenital anomaly in which the cerebellum and medulla oblongata, which
is elongated and flattened, protrude into the spinal canal through the foramen magnum. It is classified into
three types according to severity: type I involves prolapse of the cerebellar tonsils into the spinal canal
without elongation of the brainstem.” Dorland’s at 1098.

compatible with a very small syringohydromyelia;30 and a small focus of T2 hyperintensity within
the inferior T11 vertebral body and may represent more recent development of a Schmorl node31.
Ex. 2 at 31. Additionally, that MRI revealed that Petitioner had “degenerative changes of the
thoracic spine with multilevel minimal disc bulges,” but that there was “no significant thoracic
spinal canal stenosis.” Id.

                             ii. EEG Findings

       Petitioner underwent an electroencephalography (EEG)32 on June 13, 2011, which revealed
normal results. Ex. 5 at 18; Ex. 13 at 12.

                3. Petitioner’s Relevant Medical History from January 2012 through April 2012

       On February 6, 2012, Petitioner was examined by Dr. Posner for episodes of rectal bleeding
(see Ex. 4 at 2); and again on February 13, 2012, for “fatigue and general malaise occurring over
a period of three to four days” (id.). On her visit of February 13, 2012, Petitioner was diagnosed
with “[n]onspecific malaise, possibly due to viral illness with resolution.” Id.

       On February 24 and April 18, 2012, Petitioner visited with her primary care doctor for her
bloody stools. Ex. 2 at 17-18. The remainder of the text on that medical record is illegible. Id.

       Petitioner visited Dr. Wang on March 27, 2012, for complaints of headaches. Ex. 13 at 17-
19. Dr. Wang noted that Petitioner has a medical history of lupus, and recorded Petitioner’s
descriptions of her headaches, which she relayed as causing “tingling and numbness in her
extremities with her headache.” Id. at 17. Upon examination, she was assessed as having “basilar
migraine.” Id. at 19.

       Petitioner again visited Dr. Wang for her headaches on April 16, 2012. At that time, she
reported that she was “having a new concern with numbness and tingling to the upper and lower
extremities,” which Dr. Wang deemed as being “consistent with peripheral neuropathy for upper
and lower extremities.” Ex. 13 at 15. Dr. Wang ordered additional testing to rule out certain

disorders, including electromyography (EMG) 33 and nerve conduction studies (NCS) of the upper
and lower extremities, and an MRI of the brain. Id. Petitioner had her EMG and NCS study done
on April 23, 2012, which yielded normal results. Id. at 7.

        On April 24, 2012, Petitioner presented for her consultation with Dr. Posner as a
wheelchair-bound patient. Ex. 4 at 1. Dr. Posner noted that Petitioner “was last evaluated in this
office on February 13, 2012 and her clinical condition has changed radically since that visit.” Id.
Upon examination, Dr. Posner noted that Petitioner’s exam was “noteworthy for a disassociation
between [her] affect being somewhat lighthearted compared to the profound motor difficulty” that
she was experiencing at that time, especially in light of the fact that Petitioner was experiencing
those symptoms “without obvious localizing neurologic signs.” Id. Dr. Posner additionally noted
that there was still “no clear objective indication of lupus cerebritis or transverse myelitis,” and
recommended that she follow up with her neurologist. Id. Her laboratory testing performed at
that time revealed normal results, with positive antibodies for an ANA screen and Sjögren’s
antibodies (“SS-A” and “SS-B”).34 Id. at 10-12.

        Petitioner presented to St. Joseph’s Hospital’s emergency department on April 25, 2012,
and was admitted to the neurology service with complaints of continued worsening of paresthesia
and weakness in her bilateral lower extremity (“BLE”) for the past month. Ex. 33-1 at 1. At that
time, Petitioner reported that she “was in her usual state of health up until 1 year ago when she
started developing BLE [bilateral lower extremity] numbness and tingling.” Id. Additional
examinations were ordered to properly assess her care. Id. at 3.

         On April 26, 2012, Petitioner had an inpatient rheumatology consultation with Gabriel
Colceriu, M.D. Ex. 33-1 at 41-43. At that time, Petitioner relayed that approximately one year
ago, she “started developing all of a sudden, severe headaches, migraines, brain fogginess, all-over
pain and hearing issues.” Id. at 41. That note also reflects that Petitioner and her family “wonder
if there is an association with the Gardasil vaccination that she went through a few months before
the development of the symptoms.” Id. Dr. Colceriu planned for Petitioner to undergo further
testing with a plan to tailor Petitioner’s treatment depending on those results. Id. at 43.

       Petitioner underwent an MRI of her cervical spine on April 26, 2012, which her
neuroradiologist interpreted as reflecting “[f]indings worrisome for demyelination.” Ex. 2 at 9. On
that same date, Petitioner also underwent an MRI of her lumbar and thoracic spine, which both
revealed unremarkable results. Id. at 11-12. She similarly underwent a brain MRI with contrast,
the results of which were interpreted by her treating neuroradiologist as being “suspicious for

both the IgG index and the oligoclonal band study were listed as QNS (quantity not sufficient).

                4. Petitioner’s Relevant Medical History since April 2012

        Since April 2012, Petitioner continued to consult with her primary care doctor, with MS
now included in the differential diagnosis. See Ex. 8 at 1, 9, 11, 15, 18 (multiple sclerosis listed
under “Active Problems,” “Past Medical History,” or “Assessments” in Petitioner’s treatment
notes of: August 30, 2012; October 11, 2012; November 19, 2012; January 24, 2013; and March
22, 2013); see also Ex. 2 at 1, 3 (treatment note recording a diagnosis of MS on January 8, 2013;
and May 2, 2013). She also continued to have abnormal rheumatology findings upon laboratory
testing. See Ex. 8 at 1, 56-62; Ex. 15-1 at 5-14.

        On June 9, 2012, Petitioner underwent brain imaging, which continued to reveal evidence
of lesions. Ex. 10 at 2-3. She had an MRI of the cervical spine which revealed resolution of
abnormal enhancement at C3-C4 on the right, and otherwise, no significant change in lesions at
C2-C3, C3-C4, and C5-C6 when compared to the MRI of April 26, 2012. Id. at 4. She also had
an MRI of the thoracic spine at that time, reflecting a “small focus of T2 hyperintense signal within
the cord at the level of T7-T8” -- results that her neuroradiologist interpreted as “likely
represent[ing] a demyelinating lesion” in light of Petitioner’s prior medical history and previous
thoracic spine imaging. Id. at 5-6.

        On September 13, 2012, Petitioner saw Kumaraswamy Sivakumar, M.D., at the
Neuromuscular Research Center, presenting with weakness in the “distal, proximal, upper
extremities, and lower extremities.” Ex. 14 at 1. Upon examination, Dr. Sivakumar noted, among
other things, that Petitioner’s “clinical serological and therapeutic response was consistent with
systemic lupus.” Id. at 3. Dr. Sivakumar additionally noted that, at that time, he considered
“multiple sclerosis unlikely given monophasic illness and improving CNS lesions.” Id. at 3.

        Petitioner presented to Barrow NeuroImmunology on October 30, 2012, at which time her
treating physician recorded a detailed medical history given by Petitioner. Ex. 9 at 16-20. That
history recorded in her medical records, reflects, in relevant part, as follows:

        Her current symptomology began in April 2011, prior to this time she had been
        relatively healthy except for a few episodes of recurrent peritonsillar abscesses. In
        February 20[11],36 she had received a vaccination for Gardasil, despite being HPV
        positive. In April 2011 she suddenly awoke with a multitude of symptoms, which

35
  An MS – CSF panel measures immunoglobulins (IgG) as well as the number of oligoclonal bands that
are present in the CSF. Finding four or more CSF-specific bands is consistent with MS, as is a CSF IgG
index of >0.85. Multiple Sclerosis (MS) Profile, MAYO CLINIC, MAYO MEDICAL LABS, https://www.mayo
medicallaboratories.com/test-catalog/Clinical+and+Interpretive/83305 (last visited July 30, 2018).
36
  That notation is in error regarding the month and year (recorded as “February 2001”) in which Petitioner
received her HPV vaccine. Ex. 9 at 16.

                                                   16
        she brings to us on a list.

Ex. 9 at 16. Petitioner additionally relayed that “she continued to have most of her symptoms but
was managing until April of 2012,” at which time “she initially noticed tingling in her legs,” and
“in the course of one week,” she was “no longer able to walk.” Id. at 17. Upon examination,
Petitioner’s treating physician assessed her as meeting the “2010 McDonalds criteria for clinically
definite MS based on clinical history and radiologic progression.” Id. at 20. Her treating
neurologist also noted that Petitioner “likely has a concurrent systemic inflammatory process due
to positive serologies and family history[;] however it is not clear to us that she meets diagnostic
criteria for SLE or Sj[ö]gren’s.” Id. That record additionally reflected her treating physician’s
impression of the alleged link between HPV and Petitioner’s present condition, stating that “[i]t is
unclear of the role of Gardasil in her condition, however, there are case reports/series of Gardasil
preceding multifocal and atypical demyelinating syndromes” (id. at 20).

        Petitioner again visited Barrow NeuroImmunology for further consultations for her MS
diagnosis on February 20 and May 3, 2013. On both of those visits, her treating physician noted
the unclear role of Petitioner’s Gardasil vaccination on her condition, but also made general
references to the existence of case reports mentioned during her visit of October 30, 2012. Ex. 9
at 4, 14.

        Petitioner continued to seek care for her aggressive form of MS throughout 2013. Her
brain imaging reflected findings compatible with demyelinating lesions. See Ex. 2 at 1-2; Ex. 18
at 1-8; Ex. 20 at 1-29.

       The record additionally reflects a letter written by Petitioner’s primary care doctor, Dr. Sy,
dated March 5, 2015, in which Dr. Sy states that “[i]n the following weeks” after Petitioner’s HPV
vaccination of January 19, 2011, Petitioner “began to have symptoms that were initially somewhat
vague in nature.” Ex. 32 at 1. Furthermore, Dr. Sy states the following in that letter:

        At the time of her [initial] evaluations, I did not think to connect her symptoms to
        the Gardasil vaccine. However in retrospect it seems very plausible there was a
        connection to the vaccine. Previous notes by the specialists had indicated her
        symptoms started in April 2011. However she did have symptoms prior to this
        time, the symptoms were just more vague in nature and didn’t come to our attention
        until later in the course of the disease. April 2011 was when she presented to the
        emergency room, not when the symptoms began. As evidenced by her call
        requesting ENT evaluation, she had at least some symptoms in February, 2011.37
        An admission note from St. Joseph’s hospital in 4/25/1238 documents her symptoms
        as starting 2 weeks after the Gardasil vaccine was given.

37
  Dr. Sy notes that, in February 2011, Petitioner complained of inflammed glands, sore throat, and ear
pain. See Ex. 32 at 1.
38
  Dr. Sy makes a vague reference to the records from Petitioner’s treatment at St. Joseph’s Hospital’s
emergency department on April 25, 2012 (see Ex. 33-1), but does not give a specific citation to the exact
record she is referring to. See Ex. 32 at 1. Dr. Sy was mistaken in her statements in that letter, however,
as her statements were based on an incomplete examination of the entirety of Petitioner’s medical records

                                                    17
Ex. 32 at 1.

        B. Additional Factual Allegations Made in Support of Petitioner’s Claim

            1. Affidavit of Petitioner

        Petitioner signed an affidavit on November 5, 2014. See Ex. 27 at 2. Petitioner first
described herself prior to the HPV vaccination of January 19, 2011, averring that she was a student
in the honors college at Arizona State University studying Civil Engineering. Id. at 1, ¶¶ 3-4. She
lived a very physically active lifestyle, which included playing sports and riding her bike around
Tempe, Arizona. Id., ¶5.

        Petitioner next described her state of health after her HPV vaccination of January 19, 2011.
Specifically, she averred that in early February 2011, she began to feel “very sleepy,” “generally
weak all over,” felt “constantly tired,” and had “body pain.” Ex. 27 at 1, ¶7. She stated that her
feelings of weakness and discomfort got worse over time, and that her family “knew something
was really wrong with me” when she visited her family over college spring break. Id., ¶8. She
additionally stated that by March 2011, she was “no longer participating in [her] normal activities
and was having a hard time physically doing daily activities.” Id., ¶9. Notably, she alleged that
she had “early signs of issues with walking” prior to April 2011 (id., ¶10), but that she did not
realize the connection until those symptoms worsened in April 2011, at which time she had “all
over pain and paralysis” (id., ¶11).

            2. Affidavit of Caylee Harrington in Case Number 14-212V

        Petitioner also submitted an affidavit in case number 14-212V, as discussed supra at
Section I(A), signing that affidavit on March 13, 2014. Ex. A at 2. Respondent filed that affidavit
into the record, as certain of Petitioner’s allegations in that affidavit are at variance with her

since her admission to the emergency room on April 25, 2012. For one, Petitioner’s emergency department
records of April 25, 2012 reflect that Petitioner reported she “was in her usual state of health up until 1 year
ago when she started developing BLE [bilateral lower extremity] numbness and tingling.” Ex. 33-1 at 1.
That is, according to the history provided by Petitioner to her emergency department physician on April 25,
2012, she placed the onset of her symptoms around April of 2011. Id. Second, while that record does
reflect that Petitioner relayed to her emergency department physician that her symptoms were “preceded
by getting a Gardasil shot 2 weeks prior” (id. at 1), that statement is further explained by what she relayed
just one day later to another doctor during her inpatient stay, Dr. Gabriel Colceriu, on April 26, 2012 (id.
at 41-43). During her consultation with Dr. Colceriu on April 26, 2012, Petitioner once again relayed that
she started experiencing symptoms “[a]bout a year ago,” but that she and her family “wonder if there is an
association with the Gardasil vaccination that she went through a few months before the development of
the symptoms.” Id. at 41. In other words, Petitioner and her family relayed to another physician on April
26, 2012, their suspicions that Petitioner’s Gardasil vaccine administered “a few months before the
development” of her symptoms could possibly be related to her then-current condition on April 26, 2012.
Id. I also point out that, despite Petitioner relaying her suspicions of a vaccine-related cause of her
symptoms to Dr. Colceriu, he did not attribute her symptoms to her Gardasil vaccination, despite noting
that “[e]xtensive records from the outpatient setting were reviewed” at that time. Id. at 43.

                                                      18
statements in this case. Notably, in that affidavit, Petitioner averred that she felt healthy until the
middle of March 2011, at which time her post-HPV vaccination symptoms began. Ex. A at 1, ¶ 5.
Petitioner also stated as follows:

       After the middle of March, 2011, I began to experience (in addition to other
       symptoms) intermittent bilateral upper extremity, intermittent facial numbness,
       bilateral lower extremity numbness and tingling; neck and back pain, pressure in
       the ears, dizziness, brain fog, confusion, decreased memory and muscle weakness.

Ex. A at 1-2, ¶7.

           3. Affidavit of Catherine Harrington (“Ms. Harrington”)

       Petitioner’s mother, Catherine Harrington, signed an affidavit on November 5, 2014. See
Ex. 28 at 2. Ms. Harrington stated that she spoke to her daughter “almost daily” (id. at 1, ¶5), and
described her state prior to the HPV vaccination of January 19, 2011, as one in which she led a
very active lifestyle enjoying racquetball, horseback riding, and bike riding (id., ¶4).

        Ms. Harrington also described Petitioner’s state after her HPV vaccination of January 19,
2011. She asserted that Petitioner began to complain of her symptoms in February 2011,
describing Petitioner as feeling weak in most of their conversations, with her weakness gradually
progressing until her spring break in March 2011, at which time she complained of “fatigue and
an over-all ill feeling.” Ex. 28 at 1, ¶ 6. Moreover, Ms. Harrington asserted that, by March 2011,
“Petitioner was no longer able to participate in her normal activities” (id., ¶7). She stated
Petitioner’s symptoms included “lethargy,” “cognitive dysfunction,” difficulty walking, and
“severe migraines” (id., ¶10).

        Ms. Harrington relayed that she originally thought that Petitioner’s symptoms were due to
her “being over extended,” as she was a full-time student and working part-time. She also thought
her symptoms were due to Petitioner’s depression. Ex. 28 at 1, ¶8. Moreover, Ms. Harrington
stated that Petitioner’s symptoms progressed to her eventual emergency room visit in April 2011
(id., ¶11), at which time her symptoms had “progressed to transient paralysis and over all pain”
(id., ¶12). She additionally relayed that Petitioner continues to experience these symptoms
periodically and with varying intensity. Id. at 2, ¶13.

           4. Affidavit of Michael Collier

        Mr. Collier signed an affidavit on November 5, 2014. See Ex. 29 at 2. He has known
Petitioner since early 2010 when they began dating; they eventually moved in together in May
2010. Id. at 1, ¶¶3, 6. Mr. Collier averred to Petitioner’s state of health prior to her HPV
vaccination of January 19, 2011, asserting that she led an active lifestyle, which included rock
climbing, shooting, fishing, hiking, and cooking, among other activities. Id., ¶¶6-9.

       Mr. Collier additionally described Petitioner’s state after her HPV vaccination of January
19, 2011. He asserted that as of February 2011, he noticed that “Petitioner was not the same” as
she was “feeling very tired and weak” (Ex. 29 at 1, ¶11), with additional symptoms of

                                                  19
lightheadedness, neck stiffness, and soreness (id., ¶12). Mr. Collier stated that her symptoms
continued to progress to the point that she was unable to hold a conversation, causing her friends
to encourage her to consult a doctor. Id., ¶12. He additionally stated that, by mid-March 2011, “it
was clear to me that something significant was really wrong with her.” Id. at 2, ¶13. Those
symptoms worsened over time, eventually causing Petitioner to use a wheelchair while at home
(id., ¶14).

           5. Affidavit of Treating Nurse Practitioner, Teresa Becker, FNP

        Ms. Becker signed an affidavit on December 11, 2014. See Ex. 30 at 2. Ms. Becker averred
to being a treatment care provider for Petitioner prior to 2008, at which time she was operating a
private practice. She represented that Petitioner’s medical records were shredded at the closing of
her practice. Id. at 1, ¶¶ 3, 6. Ms. Becker stated that she mainly provided routine health care to
Petitioner prior to 2008 (id., ¶7), observing that she was a “physically healthy young girl” (id.,
¶10), who received counseling by another treatment provider for her depression (id., ¶8).

           6. Affidavit of Treating Licensed Professional Counselor, Julie Nicholson

         Ms. Nicholson signed an affidavit on December 18, 2014. See Ex. 31 at 2. Ms. Nicholson
averred to briefly being a treatment care provider for Petitioner in either 2004 or 2005, while
operating a private practice; she also stated, however, that Petitioner’s medical records were
shredded at the closing of her practice. Id. at 1, ¶¶ 4-5. Ms. Nicholson stated that she only briefly
provided treatment to Petitioner for her situational depression, that Petitioner eventually overcame
her situational depression; she described Petitioner as an otherwise healthy young girl. Id. at 1-2,
¶¶ 6, 9.

   III. ISSUES TO BE DETERMINED

        The issues to be determined are: (1) what was the date of onset for Petitioner’s MS; and
(2) did Petitioner’s receipt of a HPV vaccine on January 19, 2011, cause her MS.

   IV. SUMMARY OF EXPERT WITNESSES’ QUALIFICATIONS AND OPINIONS

       In this case, each side relies upon the reports of medical experts. Lawrence Steinman,
M.D., provided an opinion on behalf of Petitioner, while (1) Richard Tenser, M.D., and (2) Harry
Schroeder, M.D., Ph.D., provided an opinion on behalf of Respondent.

       A. Petitioner’s Expert – Lawrence Steinman, M.D.

           1. Qualifications

       Dr. Steinman received his medical degree from Harvard University in 1973. Ex. 48 at 1.
Dr. Steinman completed his residency training in pediatric and adult neurology at Stanford
University Hospital. Id. He became board-certified in neurology from the American Board of
Psychiatry and Neurology in 1984. Id. at 2.

                                                 20
        Dr. Steinman started as an Assistant Professor at Stanford University in the Departments
of Neurology and Pediatrics in 1980, and has held the position of Professor since 1991. Ex. 48 at
1. From 2002 to 2011, he served as Chairman of Stanford University’s Program in Immunology,
and as Incumbent Zimmermann Chair of Neurological Sciences, Neurology, and Pediatrics, from
2008 to present. Id. Dr. Steinman holds numerous patents relating to the treatment of MS and
other autoimmune disorders, has served as an editor for several prestigious journals, and has co-
authored more than five hundred publications throughout his career. Id. at 1-46. In 2011, Dr.
Steinman received the Charcot Prize from the International Federation of MS Societies for lifetime
achievement in MS research. Ex. 35 at 2.

           2. Medical Opinion

           a. Onset

        Dr. Steinman briefly opines as to the onset of Petitioner’s MS symptoms, stating that the
onset of “clinical MS began no earlier than mid-April 2011.” Ex. 35 at 1, emphasis in original;
see also id. at 3 (“the onset of clinical symptoms of MS, began sometime in April of 2011.”) He
specifically points to Petitioner’s emergency room admission on April 21, 2011, citing to her
complaints of “general weakness” as the start of her MS symptoms. Id. at 3. Dr. Steinman also
points to Petitioner’s subsequent complaints recorded in the medical records for various non-
specific symptoms, such as: “distant affect” (citing primary care doctor’s impression on April 22,
2011), and “malaise and fatigue” (citing her MRI of April 27, 2011). Id., internal citations omitted.
He discounts the unremarkable results of Petitioner’s MRI conducted on April 27, 2011, revealing
no evidence of MS, as not being probative regarding her MS onset because “contrast was not
given” at that time. Id. at 3.

        While Dr. Steinman acknowledges that Petitioner’s medical records reflect that her treating
physicians believed she concurrently suffered from “other connective tissue diseases,” including
Lupus and Sjögren’s syndrome, he did not articulate how symptoms from those disorders could be
differentiated from Petitioner’s purported onset of MS symptoms starting in mid-April 2011. See
Ex. 35 at 32.

           b. Did the Receipt of the HPV Vaccination on January 19, 2011 Trigger
              Petitioner’s MS?

                   i. General Causation (Althen Prong One)

        Dr. Steinman devotes a substantial majority of his first expert report to explaining the
theoretical underpinning of his general causation opinion in this case -- i.e., how the HPV
vaccination can lead to an autoimmune disorder such as MS, via the mechanism of molecular

                                                 21
mimicry.39 See Ex. 35 at 4-31. The crux of Dr. Steinman’s molecular mimicry theory can be
summarized as follows: (1) as shown in certain foundational literature, the human papillomavirus
shares certain molecular similarities with myelin basic protein (MBP)40 -- a protein critical for the
proper functioning of the nervous system; (2) under experimental conditions, when injected with
the human papillomavirus, cells of the nervous system formulate “antibodies to HPV” (i.e.,
proteins naturally produced by the immune system to neutralize the threat from the human
papillomavirus) causing cross-reactivity with the myelin basic protein; (3) this cross-reaction
phenomenon between HPV antibodies and myelin basic protein can reach a certain threshold, at
which time an immune reaction induces causing “clinical neuroinflammation and paralysis in the
EAE [Experimental Autoimmune Encephalomyelitis] model of MS”41 -- an experimental mice
model widely used in MS drug research42; and (4) this theoretical concept of “molecular mimicry,”
as demonstrated in an EAE mice model, can be analogized to the human body, and, according to
Dr. Steinman, can serve as a “strong scientific basis for how the HPV vaccination can trigger MS”
in humans. Ex. 35 at 26, emphasis in the original.

        In his first expert report, Dr. Steinman systematically discusses the literature underlying
the theoretical basis to support the viability of his general causation theory. See generally Ex. 35.
He first describes the basic tenets of molecular mimicry43 (see Ex. 35 at 4), followed by a detailed
discussion of the specific literature that he co-authored (“the Wucherpfenning article”),44 in which

39
   I note that, on a theoretical basis, the basic biologic process of molecular mimicry has been “largely
accepted in the medical community.” Taylor v. Sec'y of Health & Human Servs., No. 13-700V, 2018 WL
2050857, at *8 (Fed. Cl. Spec. Mstr. Mar. 9, 2018). Moreover, the basic tenets of the molecular mimicry
theory have been cogently discussed in several recent Vaccine Act cases in which petitioners allege
autoimmune disorders caused by the Gardasil vaccination. See Giannetta v. Sec'y of Health & Human
Servs., No. 13-215V, 2017 WL 4249946 (Fed. Cl. Spec. Mstr. Sept. 1, 2017); Day v. Sec'y of Health &
Human Servs., No. 12-630V, 2015 WL 8028393 (Fed. Cl. Spec. Mstr. Nov. 13, 2015); Blackburn v. Sec'y

                                                    22
it was shown that the human papillomavirus shares molecular similarities with myelin basic protein
within a specific region of that protein (id. at 5). Moreover, Dr. Steinman elaborates on the
Wucherpfenning article, explaining that, in that study, he and his co-authors “showed that
antibodies to myelin basic protein eluted from the brain of a patient with multiple sclerosis
crossreact with papillomavirus.” Id. at 6. He uses that finding from the Wucherpfenning article to
analogize and extrapolate how a similar phenomenon can occur in humans given the HPV
vaccination, thus inducing inflammation of the nervous system, leading to demyelinating
conditions such as MS. Id.45

        Dr. Steinman next discusses the HPV vaccine. He describes the composition of the HPV
vaccine -- or the “Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18)” vaccine (Ex. 35
at 6) -- as being a “non-infectious recombinant quadrivalent vaccine prepared from the purified
virus-like particles (VLPs) of the major capsid (L1) protein of HPV Types 6, 11, 16, and 18” (id.).
In this regard, Dr. Steinman concedes that the specific components of the Gardasil vaccine were
not tested in the Wucherpfenning article. Id. at 8.46 Rather, he analogizes from that article to
explain how a specific critical antibody binding site, derived from one of the human brain tissue
samples studied in the Wucherpfenning article -- “the FK residue” -- is commonly shared “between
the L2 proteins of [the human papillomavirus studied in the Wucherpfenning article], the L1
protein of HPV used to make Gardasil…and myelin basic protein.” Id. at 11. Through such an
inference, Dr. Steinman concludes that the concept of molecular mimicry explains “how
immunization with Gardasil containing the L1 protein can lead to antibodies that cross react with
myelin basic proteins.” Id.

        Dr. Steinman additionally explains that similar types of homology as the one described
above, between the Gardasil vaccine and myelin basic protein, can be strengthened with
substitutions of amino acids at relevant binding sites. See Ex. 35 at 11-12 (Dr. Steinman’s
explanation regarding these substitutions includes his reliance upon the Hausmann47 and
Birnbaum48 articles). He further explains that when a certain threshold of homology is reached
between (1) a virus (such as the Gardasil vaccine) and (2) myelin basic proteins (such as those
studied in the tissue samples of mice), an autoimmune condition called “experimental autoimmune
encephalomyelitis” is induced in mice under laboratory conditions. Ex. 35 at 12-14; see also the

45
  Ex. 35 at 6 (“An immunization to HPV could thus induce a cross-reaction with antibodies and T cells
that react to myelin basic protein, and could thus trigger brain inflammation.”).
46
  See Ex. 35 at 8 (“The study with Wucherpfennig and colleagues … shows how antibodies to HPV types
7, 13, 40 and 32 can cross-react with … myelin basic protein. The cross-reaction to the components of
Gardasil subtypes 6, 11, 16, and 18 [were] not tested in [the Wucherpfenning article].”); see also

“Gautam 1998”49 and “Gautam 1994”50 articles. Dr. Steinman concedes that the mice model
studied in the literature relates to a specific type of immune response that is triggered in a different
clinical disease -- Acute Disseminated Encephalomyelitis (ADEM) -- but submits that ADEM can
be characterized as being “an MS like disease.”51 Ex. 35 at 14.

        Moreover, Dr. Steinman discusses the relevant literature that followed the studies noted
above, deeming those studies to provide additional support towards establishing the theoretical
viability of his molecular mimicry theory leading to autoimmunity with the HPV vaccine. See Ex.
35 at 19-26 (Dr. Steinman’s discussion of several studies, including the Birnbaum,52 Harkiolaki,53
and Hausmann54 articles). He additionally opines that the alum55 contained in the Gardasil vaccine
serves to provide a “more vigorous immune response” to this entire molecular mimicry
phenomenon that he opines occurred in this case. Ex. 35 at 26. In other words, he believes that
the alum contained in the Gardasil vaccine strengthens the molecular mimicry mechanism in
humans to induce cross-reactivity between components of the Gardasil vaccine and myelin basic
protein.

        Dr. Steinman discounts the epidemiological study that was submitted by Respondent -- the
Scheller study56 -- as not being persuasive in disproving a general association between the HPV
vaccine and clinical MS. In this regard, Dr. Steinman points out what he deems are “vast
limitations” of the Scheller study, highlighting flaws that the authors of that study articulated, and

                                                    24
the shortcomings of other similar studies.57 See Ex. 35 at 27-29. Dr. Steinman summarizes what
he perceives to be the limitations of the Scheller study, and the limitations of the additional
epidemiologic studies discussed in that article, by stating that “there is no valid study on a US
population that can establish that HPV vaccine does not associate with an increased incidence of
MS.” Ex. 35 at 29, emphasis added. In other words, he heavily discounts those articles for not
studying a US population, which he believes is not a good demographic proxy for the non-US
population studies in those articles.

                   ii. Specific Causation (Althen Prong Two)

          Dr. Steinman provides a cursory discussion as to his specific causation opinion in this case
-- i.e., whether the HPV vaccination received by Petitioner on January 19, 2011 did cause her MS.
While Dr. Steinman states the conclusion that Petitioner’s “immunization on January 19, 2011
triggered a series of immune responses to myelin that induced neuroinflammation in [her] brain”
(Ex. 35 at 32), he provides little analysis as to why that might be so in this case. Dr. Steinman
simply states that he conducted an analysis of the Gardasil package insert to reach his specific
causation opinion, but fails to provide any further elaboration of what exactly the analysis was that
he conducted while examining the contents of that package. Id.

        The support from Petitioner’s medical records that Dr. Steinman does provide for his
conclusion initially appears to be compelling. Upon closer examination of that referenced medical
record, however, it does not provide significant support for his conclusion. In Dr. Steinman’s First
Expert Report, he states that “[Petitioner]’s treating neurologists mentioned [at Ex. 9 at 14] that
Gardasil and MS had been discussed in the literature.” See generally Ex. 35 at 4. The actual
reference in that medical record reflects the following:

       [T]here is an unclear role of Gardasil vaccinations in her condition; however there
       are case reports/series of Gardasil preceding multifocal and atypical demyelinating
       syndromes, which the pt [patient] experienced and is documented in a previous
       visit.

Ex. 9 at 14. Thus, while treating neurologists from Barrow NeuroImmunology did make general
references to the existence of “case reports/series of Gardasil preceding multifocal and atypical
demyelinating syndromes,” those treating neurologists specifically noted their assessments of the
unclear role of Petitioner’s receipt of the Gardasil vaccination on her condition. Id. In short, the
citation to the medical records that Dr. Steinman uses to provide support for his specific causation
opinion in this case merely supports an unclear role that the Gardasil vaccination played in
Petitioner’s development of MS. When examining Ex. 9 at 14 (Petitioner’s Barrow
NeuroImmunology treatment visit of February 20, 2013) in the context of Petitioner’s other
treatment visits to that medical practice, the record reflects that Petitioner presented to Barrow
NeuroImmunology on several occasions: on October 30, 2012 (see Ex. 9 at 16-20); on February
20, 2013 (id. at 11-15); on March 22, 2013 (id. at 6-10); and on May 3, 2013 (id. at 1-5). In
aggregate, those visits to several different neurologists within that same medical practice reflect
that the neurologists consistently noted an assessment of an unclear role of the Gardasil vaccination

57
   Dr. Steinman copies and pastes the relevant excerpts from the Scheller study in which the authors
articulate their study’s limitations. Compare Ex. 35 at 27-29, with Ex. B at 5-7.

                                                 25
on Petitioner’s condition. See Ex. 9 at 4, 14, 20.

        I additionally note that while Dr. Steinman cites to a particular medical record in which the
treating neurologists from Barrow NeuroImmunology made references to case series/reports
regarding the Gardasil vaccine preceding demyelinating conditions in general, Dr. Steinman fails
to submit or discuss any such literature in support of his position. See generally Ex. 35 at 4. Dr.
Steinman’s mere references to literature, without actually providing that literature, and his failing
to provide any additional explanations as to what that purported literature represents, add little
weight towards Petitioner’s burden of demonstrating specific causation in this case.

                   iii. Temporal Association (Althen Prong Three)

                             1. Timing Opinion Provided in First Expert Report

       Dr. Steinman opines that the timing between Petitioner’s HPV vaccination of January 19,
2011, and the onset of Petitioner’s MS -- which, according to Dr. Steinman, occurred sometime in
mid-April 2011 -- is medically appropriate in this case. Ex. 35 at 1, 32.

        At the outset, I note that the majority of Dr. Steinman’s discussion that forms the basis of
his opinion on timing is of limited persuasive value, and serves to confound the issues when his
explanations veer into discussions of questionable relevance.58 For instance, Dr. Steinman
discusses an epidemiology study in his first expert report -- the Ahmed study59 -- which examined
a different vaccine (the Pandemrix vaccine) and a different disease (narcolepsy). Ex. 35 at 29. He
discusses the results of the Ahmed study, highlighting that the “onset of [narcolepsy] associated

58
   E.g., Ex. 35 at 1 (reflecting Dr. Steinman’s attempt to redefine the meaning of “onset” in MS patients to
argue a theory of significant aggravation: “I shall also comment on the matter of what we mean by “onset
of multiple sclerosis”. Since there are over 100 genes associated with MS, indeed the onset of MS, might
begin before birth and the ‘onset’ may be in the genome of the MS patient.”); see also Id. (“Matters like
whether immunization triggers MS, might then be considered an aggravation of an underlying genetic pre-
disposition”); Id. at 31 (“Finally it is well to remember that with over 100 genes associated with MS, it is
difficult to know when MS commences. MS may start at conception from having genes conferring
susceptibility to disease. This perspective with our understanding of the role of genes in susceptibility to
MS, makes Althen prong three a real challenge to address.”) I note, however, that significant aggravation
is not at issue in this case since Dr. Steinman did not elaborate on such a theory after his cursory remarks
noted above. See generally Dr. Steinman’s first through sixth expert reports.

  Ahmed et al., Antibodies to influenza nucleoprotein cross-react with human hypocretin receptor 2, Sci.
Transl. Med. 7, 294ra105 (2015).

                                                    26
with [the Pandemrix vaccine] far exceeded three months.” Id.60 Dr. Steinman attempts to analogize
the results of that study as support for his temporal opinion in this case -- i.e., that Petitioner’s
onset of MS symptoms can occur in a three-month time frame after her HPV vaccination. Id. Dr.
Steinman does not explain how the epidemiology results from a different vaccine and a different
disease are at all relevant to establish the appropriate temporal association in this case.61

        In a similar fashion, Dr. Steinman submits additional case reports and epidemiological
findings involving the flu vaccine and narcolepsy from several European countries, but again fails
to provide a cogent explanation as to how or why any of those studies can be analogized to the
incidence of MS occurring approximately three months after HPV vaccination. Ex. 35 at 30-31.
In fact, at the end of his lengthy discussion of the literature examining the flu vaccine and
narcolepsy, Dr. Steinman himself implicitly acknowledges his own lack of conviction in the
relevancy of those articles. See Ex. 35 at 31, emphasis added (“Whether the epidemiology of
narcolepsy associated with influenza vaccine serves as a surrogate for the time course of another
disease, multiple sclerosis, with another vaccine HPV, is a point that can be debated in court if
necessary”).

       Dr. Steinman does reference literature that is counter to his proposed timing in this case --
the Sutton study62 -- which described “four patients who developed MS following HPV
immunization” in Australia. Ex. 35 at 31. Dr. Steinman concedes that none of those four patients
had an onset of MS symptoms at three months, but discounts the results of that study due to the
small sample size, describing that study as “not easily speak[ing] for what might be the case in the
US.” Id.

      In sum, Dr. Steinman’s opinion on this issue lacks the foundational basis to explain how
the HPV vaccination can trigger Petitioner’s onset of MS three months after her vaccination.

                             2. Timing Opinion Explained in Second and Third Expert Reports

       Dr. Steinman devotes his second and third expert reports to providing a foundation for his
timing opinion in this case. See generally Exs. 40 and 42. In those reports, he primarily discusses

60
  I additionally point out that by Dr. Steinman discussing the Ahmed study, and using that study to serve
as a basis to substantiate his timing opinion in this case, he contradicts his own earlier criticisms of the
Scheller study (Ex. B), as the Ahmed study also relies on a non-US population sample for their study.
Compare Ex. 35 at 29 (Dr. Steinman criticizing the Scheller study by stating that “there is no valid study
on a US population that can establish that HPV vaccine does not associate with an increased incidence of
MS”), with Ex. 35 at 29-30 (Dr. Steinman discussing epidemiology findings conducted in non-US
populations that studied the Pandemrix vaccination and narcolepsy to extrapolate those findings to support
his temporality opinion in this case).

61
 I note that discussion and analysis of a vaccine that purportedly causes a different demyelinating disease
may be of greater persuasive value; narcolepsy is not such a disease.

                                                    27
the “Langer-Gould” article63 that he states provides a “very solid foundation” for his position. Ex.
40 at 1. He references Figure 1B of that article (see Ex. 41 at 64-65), and the authors’
interpretations of their results (id. at 62), providing the following relevant text from that article:

        In the 3 years prior to symptom onset (or the index date), HPV vaccination was
        common among females aged 9 to 26 years (controls, 38.1%; and cases, 39.1%)
        (Figure 1B), but the number of cases in this subgroup was small (n = 92). Based
        on these few cases and the 459 corresponding controls, we observed a statistically
        nonsignificant trend toward an increased risk of MS but not CIS or ADEM within
        the first 3 months after HPV vaccination (Figure 1B). The number of vaccinated
        individuals 30 days before symptom onset or before the index date for the controls
        was too low to draw any conclusions (Figure 1B).

Ex. 40 at 2, quoting Ex. 41 at 62. Dr. Steinman argues that the discussion regarding a “statistically
nonsignificant trend toward an increased risk of MS…within the first 3 months after HPV
vaccination” described above meets his burden to “satisfy the criterion of the preponderance of
evidence” on this issue. Ex. 40 at 2.

         I note that Dr. Steinman’s discussion on the Langer-Gould article is unpersuasive. He
initially overstates the strength of that article as supportive of his position, stating that the article
provides a “very solid foundation” for his timing opinion. Ex. 40 at 1. Instead of further explaining
why that article provides a strong foundation for his opinion, Dr. Steinman’s subsequent discussion
veers into his own legal opinion as to the appropriate standard in Vaccine Act cases (see Ex. 40 at
2-3) -- a discussion I find to be unpersuasive.

         Additionally, while Dr. Steinman selects results that support his proposition from the
Langer-Gould article, he ignores the overall finding of that study, that the authors found “no
increased risk of CNS ADS [central nervous system demyelinating syndromes] 30 days after
vaccination” -- a finding which the authors themselves interpreted as “arguing against causality”
of vaccines triggering MS, or any other central nervous system demyelinating syndromes. Ex. 41
at 66. When asked to clarify his opinion regarding this inconsistency, Dr. Steinman’s third expert
report points out what he perceives as major flaws in that study,64 thus undercutting his own cited
literature.

               a. Qualifications

       Dr. Tenser received his medical degree from State University of New York (SUNY)
Upstate Medical School in 1968. Ex. D at 1. Dr. Tenser completed his residency training in
neurology at Yale University School of Medicine, serving as Chief Resident during his final year.
Id. He became board-certified in neurology from the American Board of Psychiatry and
Neurology in 1974. Id. at 2.

        Dr. Tenser started as an Assistant Professor at The Pennsylvania State University College
of Medicine in the Departments of Medicine (Neurology) and Microbiology in 1976, and has been
a full Professor at the university since 1986. Ex. D at 1. He has served as a scientific reviewer for
several renowned scientific journals, and has been a member of several prestigious professional
medical societies. Id. at 2-4. He states that he has published over one hundred articles in the areas
of virology and MS. Ex. C at 1. Dr. Tenser also cares for a large MS patient population in his
clinical practice, personally following more than 500 MS patients. Ex. C at 1.

               b. Medical Opinion

                    i. Onset

        Dr. Tenser opines that Petitioner was correctly diagnosed with MS in April 2012, pointing
to the medical records from that time reflecting “myelitis, with abnormal brain and spinal cord
MRI studies.” Ex. C at 3. Dr. Tenser refutes the statements made by Petitioner’s primary care
doctor, Dr. Sy, in a letter dated March 6, 2015 (see Ex. 32), in which she retrospectively
commented on the onset of Petitioner’s symptoms. Dr. Tenser addresses Dr. Sy’s opinion on onset
by pointing to Petitioner’s emergency room visit on April 21, 2011 (see Ex. 3 at 13), noting that
her symptoms reflected at that time were “nonspecific as far as MS is concerned.” Ex. C at 3. He
explains that the neurological exam conducted in April 2011 did not reveal a history of “loss of
vision or diplopia, focal weakness/sensory loss” (id.), and did not reflect abnormalities in motor
functions, coordination, and deep tendon reflexes (“DTR”) -- all symptoms he deems are “usually
noted in patients with MS” (id. at 8).

        Dr. Tenser acknowledges that while Petitioner’s complaints in April 2011 would not
suggest MS, he concedes that MS is “a very variable illness,” and that symptoms among patients
often differ. Ex. C at 3. Irrespective of that concession, Dr. Tenser opines that the normal brain
MRI in April 2011 goes “very much against” an MS diagnosis at that time.65 Id. Furthermore,

65
  In Dr. Steinman’s fifth expert report, he rebuts this point from Dr. Tenser, stating that Petitioner’s MRI
of April 27, 2011, was done without contrast; he opines that if an MRI with contrast had been conducted at
that time, then her MRI results “could certainly have demonstrated MS.” Ex. 46 at 5. Dr. Tenser, in turn,
counters that point in his rebuttal expert report, stating that, regardless of the fact that the MRI was done
without contrast, “[a]bnormalities typical of MS were not seen” which still indicates an MS diagnosis was
not medically appropriate at that time. Ex. EE at 3. Specifically, Dr. Tenser notes:

        I think it very unlikely for a contrast-enhancing brain lesion in MS to not be seen on standard
        nonenhanced T2 imaging, and the MRI of April 27, 2011 did not show T2 abnormality.

                                                     29
Dr. Tenser points out that, even if Petitioner’s clinical neurology exam conducted on April 21,
2011, which yielded normal results, can be discounted because it was conducted by an emergency
room physician and not a neurologist, her subsequent normal neurology exam conducted by her
neurologist on June 10, 2011 (see Ex. 13 at 29), undercuts the conclusion that Petitioner had MS
symptoms at that time. Id.

        Additionally, Dr. Tenser points to Petitioner’s normal results from her cerebrospinal fluid
testing on May 18, 2011 (see Ex. 5 at 16), but acknowledges that “MS-related cerebrospinal fluid
testing” was not performed at that time. Ex. C at 3.

        While he acknowledges that Petitioner’s “mild leg weakness” during her visit with a
neurologist on July 1, 2011 could possibly be evidence of the onset of her MS, he discounts that
possibility by pointing to other records around that time frame which make that possibility
unlikely. See Ex. C at 3 (discussing Ex. 13 at 27). Specifically, he points to the fact that (1) her
“coordination” and “DTR’s” [deep tendon reflexes] were normal upon examination on July 1,
2011, and (2) that on her subsequent visit on August 12, 2011, weakness was not noted as a
complaint at that time, deeming these as “early” neurological signs that are important in
distinguishing MS from other conditions.66 Id. Dr. Tenser also points to Petitioner’s clinically
normal neurology exam in August 2011 (see Ex. 22) as supportive of his position that the onset of
Petitioner’s MS was not in April 2011. Id.

        Dr. Tenser summarizes Petitioner’s non-specific symptoms and abnormal laboratory
studies67 in the spring of 2011, as possibly being the result of “inflammatory,” and “collagen-
vascular diseases” -- from Sjögren’s syndrome and Lupus -- i.e., both diseases for which Petitioner
was being treated. Ex. C at 4. Additionally, he points out that Petitioner’s medical records support
her improvement with steroidal treatments, with deterioration of her condition when steroids
decreased -- a clinical course of disease progression that, according to Dr. Tenser, is “much more
typical [of an] inflammatory, collagen-vascular disease than MS.” Id.

       Dr. Tenser additionally opines that the combination of: (1) “clinically apparent leg
numbness and weakness,” (2) her brain MRI of April 27, 2012, reflecting abnormal and enhanced
multiple white matter abnormalities, and (3) an abnormal cervical spinal cord MRI conducted on
April 27, 2012, reflecting several lesions enhanced, all point towards Petitioner’s onset of MS

Ex. EE at 3. In other words, Dr. Tenser opines that it would be very unlikely that Petitioner’s MRI results
of April 27, 2011 would not reflect lesions of the brain, if in fact such lesions existed. Id. Moreover, Dr.
Tenser believes that when examined in the aggregate, Petitioner’s medical condition in mid-April --
including the lack of typical MS symptoms in her neurological history, the lack of findings on a neurological
exam, and the lack of brain MRI abnormalities of the type seen in MS patients -- also suggests she did not
experience onset of MS in April 2011. Id. at 2-3.
66
     See Ex. 13 at 27, 23.
67
   Dr. Tenser specifically highlights the abnormal laboratory studies from April 2011 that reflected
abnormal levels of ANA, SS-A, SS-B, and rheumatoid factor. Ex. C at 7. See explanation of those
laboratory testing factors at n. 17 and 34, supra.

                                                     30
being sometime in the “spring of 2012,” and not in April of 2011.68 Ex. C at 4.

                 ii. General Causation Opinion

         Dr. Tenser questions the applicability of Dr. Steinman’s molecular mimicry theory in
explaining how the HPV vaccination can lead to MS, opining that Dr. Steinman’s theory is
“superficially compelling.” Ex. C at 5. He criticizes Dr. Steinman’s theory as being “largely based
on knowledge of the protein primary structure” (i.e., a protein’s linear amino acid sequence), but
fails to take into account the secondary and tertiary structure of the protein. Id. at 6. He deems
this failure to be key, stating that the three-dimensional geometric form of a protein “may be very
significant for the nature of [an] immune response against the protein, and it may be more
important than the primary structure.” Id. In sum, Dr. Tenser considers molecular mimicry to be
an interesting theory needing further investigation, but does not deem it to be compelling here
because, in his view, it lacks substantive proof to explain how Gardasil can cause MS in general.
Ex. C at 6.

       Dr. Tenser also points to epidemiological studies that examined the association between
vaccinations and MS (“the Langer-Gould69 study), and the association between HPV vaccination
and MS (“the Scheller70 study”), as undercutting Dr. Steinman’s general causation theory in this
case.71 He points out that those studies investigated a large population size to reach their

68
    Dr. Steinman’s sixth expert report attempts to refute Dr. Tenser’s opinion regarding the timing of
Petitioner’s onset of symptoms; however, he essentially reiterates his onset opinion stated in his first expert
report, but does not add any specific points opposing Dr. Tenser’s opinion. See Ex. 47 at 2 (Dr. Steinman
stating “[i]n response to Dr. Tenser’s timeline I really have nothing to add beyond what I have already
written.”).
69
  See Ex. C at 7 (Dr. Tenser citing Langer-Gould et al., supra, at n. 63, for the following proposition: “We
found no longer-term association of vaccines with MS or any other CNS ADS [central nervous system
acquired demyelinating syndromes], which argues against a causal association.”).
70
  See Ex. C at 8 (Dr. Tenser citing Scheller et al., supra, at n. 9, for the following proposition: “qHPV
[quadrivalent human papillomavirus] vaccination was not associated with the development of multiple
sclerosis or other demyelinating diseases.”).

                                                      31
conclusion that the Gardasil vaccination “does not increase the occurrence of MS.” Id.

            iii. Specific Causation and Appropriate Temporal Association

        Dr. Tenser uses Dr. Steinman’s own work on EAE to undercut Dr. Steinman’s opinion that
ninety days post-HPV vaccination is a medically appropriate time frame between Petitioner’s
administered HPV vaccine and her purported onset of MS. See generally Ex. C at 6. Dr. Tenser
explains that EAE induced in mice is the “most commonly investigated immune model of MS,”
highlighting that even in the experimental literature where variables can be tightly controlled,
investigators do not commonly suggest disease onset of EAE ninety days after immunization. Id.
In fact, he states that “investigators typically do not report EAE more than 30 days after
immunization.” Ex. C at 6, emphasis added. Further, Dr. Tenser argues that the “Gautam 1994”
and “Gautam 1998” studies that Dr. Steinman submits as apparently supportive of his position in
fact provide more support for Dr. Tenser’s position on this point. Specifically, Dr. Tenser notes
that the Gautam 1994 and 1998 studies, which notably are studies that Dr. Steinman also co-
authored, did not find that EAE could occur after 30 days. Id. Instead, in those studies, Dr.
Steinman and his co-authors stopped following mice beyond 40 days, thus implying that even the
authors themselves did not believe that EAE occurred after that time. Id.

        Dr. Tenser additionally opines that Dr. Steinman’s argument regarding the precise meaning
of onset for MS patients (see generally Ex. 35 at 1), is a “vague and unhelpful argument,” even
referring to that discussion as nothing more than a “straw-man argument.” Ex. C at 6-7. As a
counter to Dr. Steinman’s point on this issue, Dr. Tenser states that the onset of Petitioner’s MS
was in April 2012 -- i.e., approximately 15 months after her Gardasil vaccination -- thus making a
“causal relationship between Gardasil and the development of MS very unlikely.” Id. In the
alternative, Dr. Tenser states that, even assuming that Petitioner’s onset of MS was in mid-April

71
   Dr. Steinman’s fifth expert report attempts to refute Dr. Tenser’s reliance on the Langer-Gould and
Scheller studies by once again highlighting what he believes are flaws in those studies. Compare Ex. 46 at
1-4, with Ex. 35 at 27-29. In sum, Dr. Steinman believes that those two studies are flawed in various ways
that do not make them appropriate proxies to the effects of the HPV vaccination on a US population. See
generally Ex. 46. Dr. Tenser, in turn, counters in his rebuttal expert report, classifying these criticisms by
Dr. Steinman as “very much a straw-man argument.” Ex. EE at 1. He points out that “lesser sun exposure”
is “currently the most MS-discussed environmental factor” that is associated with “greater frequency of
MS.” Id. He states that the Scheller study examined a Scandinavian population, “living in northern latitudes
with less sunlight exposure, who would be at greater risk for developing MS,” thus making the demography
of the Scheller study even more powerful in its implications since “if no correlation of the HPV vaccine
and development of MS were demonstrated for Scandinavians, it really goes against a putative correlation.”
Id. at 1-2. In attempting to refute Dr. Tenser’s reliance on those two studies, Dr. Steinman’s fifth expert
report also veers into discussions about his legal opinions on the appropriateness of epidemiological studies
in the Vaccine Program. See Ex. 46 at 1 (“Although epidemiology is important to guide public health
decisions, it is problematic for the context of this court.”).

                                                     32
2011, as opined by Dr. Steinman, onset approximately ninety days from vaccination, is still “too
long,” by Dr. Steinman’s own research that he submits as supportive of his opinion. Id. at 8-9.

           2. Harry Schroeder, M.D., Ph.D.

                   a. Qualifications

        Dr. Schroeder received his Ph.D. in Cell Biology in 1979, and his medical degree in 1981,
both from the Baylor College of Medicine. Ex. Q at 1. Dr. Schroeder completed his residency
training in internal medicine at the University of Kentucky Medical Center, and completed his
fellowship in Medical Genetics. Id. at 2. He became board-certified in internal medicine in 1984,
and in clinical genetics in 1987. Id. at 4.

        Dr. Schroeder started as an Assistant Professor in 1988, at the University of Alabama at
Birmingham (UAB) in the Department of Medicine’s Division of Developmental and Clinical
Immunology. He has been a full Professor at that institution since 1998. Ex. Q at 2-3. He has
concurrently held a faculty position at UAB’s Department of Microbiology, where he has been a
full Professor since 1998. Id. Dr. Schroeder has been the recipient of several National Institutes
of Health (NIH) grants, has been a reviewer for well-renowned scientific journals, and has been a
member of several prestigious professional medical societies. Id. at 4-23. His CV lists that he has
co-authored over 95 peer-reviewed articles, and several book chapters and books. Id. at 24-33.

                   b. Medical opinion

                      i. Onset

         Dr. Schroeder opines that more than a year after her Gardasil vaccination on January 19,
2011, Petitioner “developed a demyelinating disorder, most likely multiple sclerosis, that led to
weakness and loss of neural function.” Ex. P at 15. He additionally states that Petitioner did not
have MS in mid-April 2011, and provided a snapshot of Petitioner’s concurrent medical conditions
at that time. Id. at 7. He highlights that Petitioner presented to the emergency room on April 21,
2011, with a complex picture reflecting -- (1) the “sudden onset of generalized weakness,
arthalgias, lightheadedness, and confusion”; (2) laboratory testing demonstrating “an elevated
ANA titer compatible with lupus,” and an elevated SS-A and SS-B “compatible with Sjögren’s
syndrome”; (3) evidence of an ongoing inflammatory state due to an elevated ESR, and (4)
“serologic evidence of recent exposure to B. burgdorferi, the cause of Lyme Disease” -- but that
none of these suggest MS. Id.

        Dr. Schroeder additionally points to the MRI performed in April 2011, noting that it did
not disclose any evidence of demyelination. Ex. P at 7. Thus Petitioner’s treating physicians did
not entertain a MS diagnosis at that time. Id. In this regard, he explains the import of an MRI
without contrast, noting this means that no “active MS lesions” would have been detectable at that
time. Ex. BB at 3. He also critically points out, however, that while no active MS lesions would
be detectable, an MRI without contrast would still reflect signs of demyelination, and her MRI in
April 2011 showed “no indication on the test result that demyelination was observed.” Id. In
summary, while Dr. Schroeder admits that definitive MRI and lumbar puncture testing for MS was

                                                33
incomplete in April and May of 2011, he points to other contextual evidence in the medical records
and laboratory testing that provides a lack of clinical or diagnostic evidence of demyelination in
the time frame surrounding Petitioner’s first emergency room visit on April 21, 2011. See
generally Exs. P and BB.

                 ii. General and Specific Causation Opinion

        Dr. Schroeder opines that while he respects Dr. Steinman’s expertise in conducting
valuable experiments in the EAE model, he questions the applicability of his molecular mimicry
theory in inducing MS specifically in Petitioner. Ex. P at 13.72

        Moreover, Dr. Schroeder provides an alternative explanation for the cause of her initial
symptoms in mid-April 2011, stating that those symptoms are more likely due to an inflammatory
state caused by Petitioner’s exposure to Borrelia burgdorferi, the bacterial species that causes
Lyme Disease, rather her Gardasil vaccination. Ex. P at 7, 15. In sum, he opines that Petitioner’s
case is similar to most other cases of MS, in that the cause of her MS is simply unknown. Id. at
15.
                iii. Appropriate Temporal Association

        Dr. Schroeder opines that Petitioner’s demyelination occurred more than a year after her
Gardasil vaccination, indicating that there is no proximate temporal relationship between the HPV
vaccination and the onset of her MS. He additionally posits that a temporal association between
Petitioner’s HPV vaccination and the onset of her MS is further unlikely due to her “intervening
history of infectious and autoimmune inflammation,” such as Lyme Disease, Lupus, and Sjögren’s
syndrome. Ex. P at 8. In other words, he explains that a temporal association between Petitioner’s
HPV vaccination and the onset of her MS more than a year later is simply medically unlikely when
accounting for the complicated intervening medical history suffered by Petitioner during that time
period.

     V. APPLICABLE LAW

        A. Petitioner’s Overall Burden in Vaccine Program Cases

       Under the Vaccine Act, a petitioner may prevail in one of two ways. First, a petitioner may
demonstrate that she suffered a “Table” injury—i.e., an injury listed on the Vaccine Injury Table
that occurred within the time period provided in the Table. § 11(c)(1)(C)(i). “In such a case,
causation is presumed.” Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317, 1320 (Fed.

72
   In both of Dr. Schroeder’s expert reports, he additionally discusses an aspect of Dr. Steinman’s theory -
- that MS is the result of an immune response to myelin basic protein (MBP). See generally Exs. P and BB.
In his rebuttal expert report, after reviewing and discussing the previously unsubmitted medical records,
Dr. Schroeder opines that his “overall opinions in this case remain unchanged,” noting that while Dr.
Steinman presents “an interesting and intriguing set of hypotheses regarding the etiology” of MS in
Petitioner, he believes that “there is insufficient data to support” Dr. Steinman’s hypotheses as it relates to
her. Ex. BB at 10. Additionally, he believes that the “timing of the development of the demyelination
makes it unlikely that the second [HPV vaccination] was the likely cause” of Petitioner’s MS. Id.

                                                      34
Cir. 2006); see § 13(a)(1)(B). Second, where the alleged injury is not listed in the Vaccine Injury
Table, a petitioner may demonstrate that she suffered an “off-Table” injury. § 11(c)(1)(C)(ii).

        For both Table and non-Table claims, Vaccine Program petitioners bear a “preponderance
of the evidence” burden of proof. Section 13(1)(a). That is, a petitioner must offer evidence that
leads the “trier of fact to believe that the existence of a fact is more probable than its nonexistence
before [she] may find in favor of the party who has the burden to persuade the judge of the fact’s
existence.” Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1324 (Fed. Cir. 2010);
see also Snowbank Enter. v. United States, 6 Cl. Ct. 476, 486 (1984) (mere conjecture or
speculation is insufficient under a preponderance standard). Proof of medical certainty is not
required. Bunting v. Sec’y of Health & Human Servs., 931 F.2d 867, 873 (Fed. Cir. 1991). In
particular, a petitioner must demonstrate that the vaccine was “not only [the] but-for cause of the
injury but also a substantial factor in bringing about the injury.” Moberly, 592 F.3d at 1321
(quoting Shyface v. Sec’y of Health & Human Servs., 165 F.3d 1344, 1352 (Fed. Cir. 1999));
Pafford v. Sec’y of Health & Human Servs., 451 F.3d 1352, 1355 (Fed. Cir. 2006). A petitioner
may not receive a Vaccine Program award based solely on her assertions; rather, the petition must
be supported by either medical records of by the opinion of a competent physician. Section
13(a)(1).

        In attempting to establish entitlement to a Vaccine Program award of compensation for a
non-Table claim, a petitioner must satisfy all three of the elements established by the Federal
Circuit in Althen. Althen requires that petitioner establish by preponderant evidence that the
vaccinations he received caused her injury “by providing: (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. at 1278.

        Each of the Althen prongs requires a different showing. Under Althen prong one,
petitioners must provide a “reputable medical theory,” demonstrating that the vaccine received can
cause the type of injury alleged. Pafford, 451 F.3d at 1355-56 (citations omitted). To satisfy this
prong, a petitioner’s theory must be based on a “sound and reliable medical or scientific
explanation.” Knudsen v. Sec’y of Health & Human Servs., 35 F.3d 543, 548 (Fed. Cir. 1994).
Such a theory must only be “legally probable, not medically or scientifically certain.” Id. at 549.

         Petitioners may satisfy the first Althen prong without resort to medical literature,
epidemiological studies, demonstration of a specific mechanism, or a generally accepted medical
theory. 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). Special Masters, despite their expertise, are not
empowered by statute to conclusively resolve what are complex scientific and medical questions,
and thus scientific evidence offered to establish Althen prong one is viewed “not through the lens
of the laboratorian, but instead from the vantage point of the Vaccine Act’s preponderant evidence
standard.” Id. at 1380. Accordingly, special masters must take care not to increase the burden
placed on petitioners in offering a scientific theory linking vaccine to injury. Contreras v. Sec’y
of Health & Human Servs., 121 Fed. Cl. 230, 245 (2015) (“[p]lausibility … in many cases may be
enough to satisfy Althen prong one” (emphasis in original)), vacated on other grounds, 844 F.3d
1363 (Fed. Cir. 2017). But this does not negate or reduce a petitioner’s ultimate burden to establish

                                                  35
her overall entitlement to damages by preponderant evidence. W.C. v. Sec’y of Health & Human
Servs., 704 F.3d 1352, 1356 (Fed. Cir. 2013) (citations omitted).

        The second Althen prong requires proof of a logical sequence of cause and effect, usually
supported by facts derived from a petitioner’s medical records. Althen, 418 F.3d at 1278; Andreu,
569 F.3d at 1375-77; Capizzano, 440 F.3d at 1326 (“medical records and medical opinion
testimony are favored in vaccine cases, as treating physicians are likely to be in the best position
to determine whether a ‘logical sequence of cause and effect show[s] that the vaccination was the
reason for the injury’”) (quoting Althen, 418 F.3d at 1280). Medical records are generally viewed
as particularly trustworthy evidence, because they are created contemporaneously with the
treatment of the patient. Cucuras v. Sec’y of Health & Human Servs., 993 F.2d 1525, 1528 (Fed.
Cir. 1993).

        However, medical records and/or statements of a treating physician’s views do not per se
bind the special master to adopt the conclusions of such an individual, even if they must be
considered and carefully evaluated. Section 13(b)(1) (providing that “[a]ny such diagnosis,
conclusion, judgment, test result, report, or summary shall not be binding on the special master or
court”); Snyder v. Sec’y of Health & Human Servs., 88 Fed. Cl. 706, 746 n.67 (2009) (“there is
nothing … that mandates that the testimony of a treating physician is sacrosanct -- that it must be
accepted in its entirety and cannot be rebutted”). As with expert testimony offered to establish a
theory of causation, the opinions or diagnoses of treating physicians are only as trustworthy as the
reasonableness of their suppositions or bases. The views of treating physicians should also be
weighed against other, contrary evidence also present in the record -- including conflicting
opinions among such individuals. Hibbard v. Sec’y of Health & Human Servs., 100 Fed. Cl. 742,
749 (2011) (not arbitrary or capricious for special master to weigh competing treating physicians’
conclusions against each other), aff’d, 698 F.3d 1355 (Fed. Cir. 2012); Caves v. Sec’y of Health &
Human Servs., No. 06-522V 2011 WL 1935813, at *17 (Fed. Cl. Spec. Mstr. Apr. 29, 2011), mot.
for review den’d, 100 Fed. Cl. 344, 356 (2011), aff’d without opinion, 475 Fed. App’x 765 (Fed.
Cir. 2012).

        The third Althen prong requires establishing a “proximate temporal relationship” between
the vaccination and the injury alleged. Althen, 418 F.3d at 1281. That term has been equated to
the phrase “medically-acceptable temporal relationship.” Id. A petitioner must offer
“preponderant proof that the onset of symptoms occurred within a timeframe which, given the
medical understanding of the disorder’s etiology, it is medically acceptable to infer causation.” de
Bazan v. Sec’y of Health & Human Servs., 539 F.3d 1347, 1352 (Fed. Cir. 2008). The explanation
for what is a medically acceptable timeframe must also coincide with the theory of how the relevant
vaccine can cause an injury (Althen prong one’s requirement). Id. at 1352; Shapiro v. Sec’y of
Health & Human Servs., 101 Fed. Cl. 532, 542 (2011), recons. den’d after remand, 105 Fed. Cl.
353 (2012), aff’d mem., 2013 WL 1896173 (Fed. Cir. 2013); Koehn v. Sec’y of Health & Human
Servs., No. 11-355V, 2013 WL 3214877 (Fed. Cl. Spec. Mstr. May 30, 2013), mot. for review
den’d (Fed. Cl. Dec. 3, 2013), aff’d, 773 F.3d 1239 (Fed. Cir. 2014).

                                                36
        B. Law Governing Analysis of Fact Evidence

        The process for making factual determinations in Vaccine Program cases begins with
analyzing the medical records, which are required to be filed with the petition. Section 11(c)(2).
The special master is required to consider “all [] relevant medical and scientific evidence contained
in the record,” including “any diagnosis, conclusion, medical judgment, or autopsy or coroner’s
report which is contained in the record regarding the nature, causation, and aggravation of the
petitioner’s illness, disability, injury, condition, or death,” as well as the “results of any diagnostic
or evaluative test which are contained in the record and the summaries and conclusions.” Section
13(b)(1)(A). The special master is then required to weigh the evidence presented, including
contemporaneous medical records and testimony. See Burns v. Sec’y of Health & Human Servs.,
3 F.3d 413, 417 (Fed. Cir. 1993) (it is within the special master’s discretion to determine whether
to afford greater weight to contemporaneous medical records than to other evidence, such as oral
testimony surrounding the events in question that was given at a later date, provided that such
determination is evidenced by a rational determination).

        Medical records created contemporaneously with the events they describe are presumed to
be accurate and “complete” such that they present all relevant information on a patient’s health
problems. Cucuras, 993 F.2d at 1528; Doe/70 v. Sec’y of Health & Human Servs., 95 Fed. Cl.
598, 608 (2010) (“[g]iven the inconsistencies between petitioner’s testimony and his
contemporaneous medical records, the special master’s decision to rely on petitioner’s medical
records was rational and consistent with applicable law”), aff’d, Rickett v. Sec’y of Health &
Human Servs., 468 F. App’x 952 (Fed. Cir. 2011) (non-precedential opinion). This presumption
is based on the linked proposition that (i) sick people visit medical professionals; (ii) sick people
honestly report their health problems to those professionals; and (iii) medical professionals record
what they are told or observe when examining their patients in as accurate a manner as possible,
so that they are aware of enough relevant facts to make appropriate treatment decisions. Sanchez
v. Sec’y of Health & Human Servs., No. 11-685V, 2013 WL 1880825, at *2 (Fed. Cl. Spec. Mstr.
Apr. 10, 2013); Cucuras v. Sec’y of Health & Human Servs., 26 Cl. Ct. 537, 543 (1992), aff’d, 993
F.2d at 1525 (Fed. Cir. 1993) (“[i]t strains reason to conclude that petitioners would fail to
accurately report the onset of their daughter’s symptoms.”).

        Accordingly, if the medical records are clear, consistent, and complete, then they should
be afforded substantial weight. Lowrie v. Sec’y of Health & Human Servs., No. 03-1585V, 2005
WL 6117475, at *20 (Fed. Cl. Spec. Mstr. Dec. 12, 2005). Indeed, contemporaneous medical
records are generally found to be deserving of greater evidentiary weight than oral testimony --
especially where such testimony conflicts with the record evidence. Cucuras, 993 F.2d at 1528;
see also Murphy v. Sec’y of Health & Human Servs., 23 Cl. Ct. 726, 733 (1991), aff’d per curiam,
968 F.2d 1226 (Fed. Cir. 1992), cert. den’d, Murphy v. Sullivan, 506 U.S. 974 (1992) (citing United
States v. U.S. Gypsum Co., 333 U.S. 364, 396 (1947) (“[i]t has generally been held that oral
testimony which is in conflict with contemporaneous documents is entitled to little evidentiary
weight.”)).

       However, there are situations in which compelling oral testimony may be more persuasive
than written records, such as where records are deemed to be incomplete or inaccurate. Campbell
v. Sec’y of Health & Human Servs., 69 Fed. Cl. 775, 779 (2006) (“like any norm based upon

                                                   37
common sense and experience, this rule should not be treated as an absolute and must yield where
the factual predicates for its application are weak or lacking”); Lowrie, 2005 WL 6117475, at *19
(“[w]ritten records which are, themselves, inconsistent, should be accorded less deference than
those which are internally consistent”) (quoting Murphy, 23 Cl. Ct. at 733)). Ultimately, a
determination regarding a witness’s credibility is needed when determining the weight that such
testimony should be afforded. Andreu, 569 F.3d at 1379; Bradley v. Sec’y of Health & Human
Servs., 991 F.2d 1570, 1575 (Fed. Cir. 1993).

        When witness testimony is offered to overcome the presumption of accuracy afforded to
contemporaneous medical records, such testimony must be “consistent, clear, cogent and
compelling.” Sanchez, 2013 WL 1880825, at *3 (citing Blutstein v. Sec’y of Health & Human
Servs., No. 90-2808V, 1998 WL 408611, at *5 (Fed. Cl. Spec. Mstr. June 30, 1998)). In
determining the accuracy and completeness of medical records, the Court of Federal Claims has
listed four possible explanations for inconsistencies between contemporaneously created medical
records and later testimony: (1) a person’s failure to recount to the medical professional everything
that happened during the relevant time period; (2) the medical professional’s failure to document
everything reported to her or him; (3) a person’s faulty recollection of the events when presenting
testimony; or (4) a person’s purposeful recounting of symptoms that did not exist. LaLonde v.
Sec’y of Health & Human Servs., 110 Fed. Cl. 184, 203-04 (2013), aff’d, 746 F.3d 1334 (Fed. Cir.
2014). In making a determination regarding whether to afford greater weight to contemporaneous
medical records or other evidence, such as testimony at hearing, there must be evidence that this
decision was the result of a rational determination. Burns, 3 F.3d at 417.

       C. Analysis of Expert Testimony

        Establishing a sound and reliable medical theory connecting the vaccine to the injury often
requires a petitioner to present expert testimony in support of his or her claim. Lampe v. Sec’y of
Health & Human Servs., 219 F.3d 1357, 1361 (Fed. Cir. 2000). Vaccine Program expert testimony
is usually evaluated according to the factors for analyzing scientific reliability set forth in Daubert
v. Merrell Dow Pharm., Inc., 509 U.S. 579, 594-96 (1993). See Cedillo v. Sec’y of Health &
Human Servs., 617 F.3d 1328, 1339 (Fed. Cir. 2010) (citing Terran v. Sec’y of Health & Human
Servs., 195 F.3d 1302, 1316 (Fed. Cir. 1999). “The Daubert factors for analyzing the reliability
of testimony are: (1) whether a theory or technique can be (and has been) tested; (2) whether the
theory or technique has been subjected to peer review and publication; (3) whether there is a known
or potential rate of error and whether there are standards for controlling the error; and (4) whether
the theory or technique enjoys general acceptance within a relevant scientific community.”
Terran, 195 F.3d at 1316 n.2 (citing Daubert, 509 U.S. at 592-95).

        The Daubert factors play a slightly different role in Vaccine Program cases than they do
when applied in other federal judicial fora. Daubert factors are employed by judges to exclude
evidence that is unreliable and potentially confusing to a jury. In Vaccine Program cases, these
factors are used in the weighing of the reliability of scientific evidence. Davis v. Sec’y of Health
& Human Servs., 94 Fed. Cl. 53, 66-67 (2010) (“uniquely in this Circuit, the Daubert factors have
been employed also as an acceptable evidentiary-gauging tool with respect to persuasiveness of
expert testimony already admitted”). The flexible use of the Daubert factors to evaluate
persuasiveness and reliability of expert testimony has routinely been upheld. See, e.g., Snyder, 88

                                                  38
Fed. Cl. at 743. In this matter, (as in numerous other Vaccine Program cases), Daubert has not
been employed at the threshold, to determine what evidence should be admitted, but instead to
determine whether expert testimony offered is reliable and/or persuasive.

         Respondent frequently offers one or more experts of his own in order to rebut a petitioner’s
case. Where both sides offer expert testimony, a special master’s decision may be “based on the
credibility of the experts and the relative persuasiveness of their competing theories.”
Broekelschen v. Sec’y of Health & Human Servs., 618 F.3d 1339, 1347 (Fed. Cir. 2010) (citing
Lampe, 219 F.3d at 1362). However, nothing requires the acceptance of an expert’s conclusion
“connected to existing data only by the ipse dixit of the expert,” especially if “there is simply too
great an analytical gap between the data and the opinion proffered.” Snyder, 88 Fed. Cl. at 743
(quoting Gen. Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997)). A “special master is entitled to
require some indicia of reliability to support the assertion of the expert witness.” Moberly, 592
F.3d at 1324. Weighing the relative persuasiveness of competing expert testimony, based on a
particular expert’s credibility, is part of the overall reliability analysis to which special masters
must subject expert testimony in Vaccine Program cases. Id. at 1325-26 (“[a]ssessments as to the
reliability of expert testimony often turn on credibility determinations”); see also Porter v. Sec’y
of Health & Human Servs., 663 F.3d 1242, 1250 (Fed. Cir. 2011) (“this court has unambiguously
explained that special masters are expected to consider the credibility of expert witnesses in
evaluating petitions for compensation under the Vaccine Act”).

           D. Consideration of Medical Literature

        Finally, although this decision discusses some but not all of the medical literature in detail,
I reviewed and considered all of the medical records and literature submitted in this matter. 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 [s]he does not
explicitly reference such evidence in h[er] decision.”); Simanski v. Sec’y of Health & Human
Servs., 115 Fed. Cl. 407, 436 (2014) (“[A] Special Master is ‘not required to discuss every piece
of evidence or testimony in her decision.’” (citation omitted)), aff’d, 601 F. App’x 982 (Fed. Cir.
2015).73

       Multiple sclerosis (MS) is characterized as a chronic inflammatory, demyelinating disease
of the central nervous system with an unknown etiology.74 Ex. 41 at 16-17, ECF No. 45-2.

73
   Although I have considered the entire record, including the voluminous medical records and medical
literature, in arriving at my decision, I will only discuss evidence specifically relevant to the resolution of
this matter. See Paterek v. Sec'y of Health & Human Servs., 527 Fed. Appx. 875, 884 (Fed. Cir. 2013).
This includes medical literature submitted by both sides. Id., at *884 (“Finding certain information not
relevant does not lead to – and likely undermines – the conclusion that it was not considered.”)
74
     Dorland’s characterizes MS, in relevant part, as follows:

                                                       39
According to the National Institute of Neurological Disorders and Stroke of the National Institutes
of Health, MS is the most common disabling neurologic disease in young adults, appearing most
often in individuals between the ages of 20 and 40 years old. The course of the disease is highly
variable, where some individuals have minimal disability, whereas others suffer increasing
disability over time. Approximately 400,000 individuals in the United States suffer from MS, with
approximately 10,000 new cases diagnosed annually. Women are two to three times more likely
to develop MS than men. See Ex. 41 at 16-17; Ex. P at 11-12.

        B. Onset of Petitioner’s MS

        After a careful consideration of the entire record of this case, I find that the onset of
Petitioner’s MS symptoms was not in mid-April 2011; rather, I find that her onset of MS symptoms
began sometime in late March 2012.

                1. Petitioner’s MS Onset Was Not in Mid-April 2011 or in the Months Prior75

       Dr. Steinman points to some evidence that weighs in favor of an April 2011 onset; this
includes Petitioner’s symptoms of general weakness, distant affect, and malaise and fatigue
reported on April 21, 2011.76

       However, after reviewing all the evidence in this case, I find the medical record evidence,
the contemporaneous assessments of Petitioner’s treating physicians, and the opinions of Dr.
Tenser and Dr. Schroeder to be more persuasive in explaining that Petitioner’s MS onset was not

        [A] disease in which there are foci of demyelination throughout the white matter of the
        central nervous system, sometimes extending into the gray matter; symptoms usually
        include weakness, incoordination, paresthesias, speech disturbances, and visual
        complaints. The course of the disease is usually prolonged, so that the term multiple also
        refers to remissions and relapses that occur over a period of many years.

Dorland’s at 1680.
75
   My conclusion in this regard, that Petitioner did not have an onset of MS in mid-April 2011, or at an
earlier point in time, is not changed by my careful consideration of the affidavits filed in this case. In
forming my opinion on onset, I generally relied on the facts set forth in the contemporaneous medical
records, as I find those records to be more reliable. See Reusser v. Sec’y of Health & Human Servs., 28 Fed.
Cl. 516, 523 (Fed. Cl. 1993) (holding that “[W]ritten documentation recorded by a disinterested person at
or soon after the event at issue is generally more reliable than the recollection of a party to a lawsuit many
years later.”). This is especially so since the record reveals that Petitioner filed an affidavit in this case
alleging that her onset of symptoms started in early February 2011, whereas her affidavit filed in case
number 14-212V (see Ex. A, ECF No. 25-1) alleged that the onset of her symptoms was after mid-March
2011. See supra at Section I(A) and Section II(B)(1)-(2).
76
  Also of note, in the Emergency Department records from April 25, 2012 Petitioner reports that “she was
in her usual state of health up until 1 year ago when she started developing BLE numbness and tingling”.
While this may support onset in April 2011, none of the experts in this case elaborated on this specific
point. I have considered this notation in determining the date of onset of Petitioner’s symptoms, but find
the evidence contrary to onset in April 2011 and in support of onset in March 2012 to be more persuasive.

                                                     40
in mid-April 2011, than Dr. Steinman’s and Dr. Sy’s opinions to the contrary. This is primarily
so because Drs. Tenser and Schroeder thoroughly support their onset opinion by references to the
relevant medical records, explaining and contextualizing Petitioner’s complex medical conditions
in the ensuing months starting from mid-April 2011. In contrast, I find Dr. Steinman’s onset
opinion to be cursory, in that it does not provide an analysis of Petitioner’s medical history as a
whole. Dr. Steinman only selectively discusses non-specific symptoms reflected in a few of
Petitioner’s medical records in the time period shortly after mid-April 2011, but fails to properly
explain how those symptoms signify an onset of MS. This contrast in the degree of explanation
becomes even more probative when one considers Petitioner’s medical records, which reveal that
in mid-April 2011 she was being treated for several other diseases, including suspected Lyme
disease, Lupus, and Sjögren’s syndrome, making it that much harder to precisely discern onset.

                       a. Discussion of Petitioner’s Medical History Provided by Both
                          Parties’ Experts

         Dr. Steinman primarily bases his onset opinion on three specific symptoms recorded in
Petitioner’s medical records that span over a week of her emergency room admission on April 21,
2011. He points to Petitioner’s complaints of “general weakness,” “distant affect,” and “malaise
and fatigue,” but fails to explain how those non-specific symptoms amount to the onset of her MS
at that time. See Steinman First Rep. at 3 and Steinman Fourth Rep. at 1-2.

       In contrast, I find Dr. Schroeder’s and Dr. Tenser’s opinions that Petitioner did not have
MS in mid-April 2011, to be far more persuasive as they provide a complete picture of Petitioner’s
complex medical condition during that timeframe. Their explanations reveal several critical points
regarding Petitioner’s condition.

        For one, Dr. Tenser effectively explains that Petitioner’s non-specific symptoms and
abnormal laboratory studies in mid-April 2011 were likely the result of Sjögren’s syndrome and
Lupus, rather than MS. He points to Petitioner’s medical records throughout 2011 and mid-2012
revealing that she was being treated for both of those diseases. He additionally points to
Petitioner’s improvement with steroidal treatments, and subsequent deterioration when steroids
were decreased, as clinically more indicative of Sjögren’s syndrome and Lupus, than MS. While
Dr. Steinman acknowledges that Petitioner suffered from those two diseases, he does not address
this point.

        Second, Dr. Tenser points to four specific neurology exams conducted on Petitioner that
do not reflect classical clinical symptoms of MS. Those clinical neurological exams were
conducted on April 21, 2011 (Ex. 3 at 13); June 10, 2011 (Ex. 13 at 29); July 1, 2011 (Ex. 13 at
27); and August 12, 2011 (Ex. 13 at 23). In the aggregate, he points out that those four neurological
exams do not reveal that Petitioner had classic symptoms of MS during that time frame.

        Third, I find persuasive Dr. Tenser’s and Dr. Schroeder’s point that, while definitive MRI
and lumbar puncture testing for MS was incomplete in April and May of 2011, other contextual
evidence in the medical records and laboratory testing does not provide clinical or diagnostic
imaging evidence of MS in that timeframe. In this regard, I note that Dr. Steinman does not
effectively discount the brain MRI testing results of April 27, 2011, which revealed normal results.

                                                 41
While he states no contrast was given when Petitioner underwent that brain MRI testing, he
provides no meaningful explanation as to how or why the use of contrast would have yielded
different results. In contrast, Dr. Schroeder explains the implications of conducting an MRI
without contrast, noting that this simply means that no active MS lesions can be detected on such
an MRI, but that signs of demyelination can still be detected. As the brain MRI conducted on
April 27, 2011 did not reflect signs of demyelination, he finds that to be evidence that Petitioner
was not experiencing demyelination at that time. Moreover, Dr. Tenser explains that it would be
“very unlikely” for a brain lesion in MS to not be seen on a “standard nonenhanced T2 imaging”
-- i.e., the type of brain MRI Petitioner underwent on April 27, 2011 -- if in fact such a lesion
existed at that time. See Ex. EE at 3. Dr. Tenser additionally explains that, when examining, in
the aggregate, Petitioner’s condition starting in mid-April 2011 -- including the lack of typical MS
symptoms in her neurological history, the lack of clinical findings on the multiple clinical
neurology exams conducted during that time period, and the lack of brain MRI abnormalities of
the type seen in MS patients -- goes against a conclusion that Petitioner’s onset of MS was in April
2011. Id. at 3-4.

        My finding that Petitioner developed MS in March 2012 is also strengthened by my close
examination of the contemporaneous medical records from January 2011 through March 2012
during which Petitioner underwent numerous medical visits. In the aggregate, those medical
records reflect that her treating physicians did not suspect/diagnose her with MS during that time
frame, with a majority of those physicians in fact suspecting other causes for Petitioner’s
symptoms at that time, such as Lupus, Sjögren’s syndrome, and/or Lyme disease. 77 See, e.g., Ex.
3 at 13-21 (Tempe St. Luke’s Hospital’s emergency room records of April 21, 2011); Ex. 12 at 3-
5 (Petitioner’s consultation with her ENT specialist, Dr. Kelsch, on July 10, 2011); Ex. 4 at 2, 5-8
(Petitioner’s consultation with her rheumatologist, Dr. Stuart Posner, on the following dates: May
17, 2011; June 9, 2011; July 8, 2011; February 6, 2012; and February 13, 2012); Ex. 13 at 23-31
(Petitioner’s consultation with her neurologist, Dr. Wang, on the following dates: June 10, 2011;
July 1, 2011; August 12, 2011; and November 22, 2011); and Ex. 5 at 50-51, 57-58 (Petitioner’s
consultation with her infectious diseases specialist, Dr. Schroeder, on the following dates: June 15,
2011; August 12, 2011; and December 13, 2011).

        I additionally note that even Petitioner’s primary care doctor during that time, Dr. Sy, did
not contemporaneously suspect that Petitioner had MS, despite her retrospective representations
to the contrary at Ex. 32, discussed in detail below. See, e.g., Petitioner’s visit with Dr. Sy on the
following dates: April 22, 2011 (Ex. 2 at 22); April 25, 2011 (id. at 21); May 2, 2011 (id. at 20);
May 4, 2011 (id. at 19); February 24, 2012 (id. at 18); and April 18, 2012 (id. at 17).

                        b. Dr. Sy’s Letter Stating Her Beliefs as to Petitioner’s Onset of MS

        As previously noted, the record of this case additionally reflects a letter written by
Petitioner’s primary care doctor, Dr. Sy, dated March 5, 2015 (and thus after this case’s initiation),
in which she retrospectively reports that Petitioner began to have vague symptoms weeks after her
HPV vaccination. Ex. 32 at 1. As support for her position, she references (1) a phone call notation

77
 The opinions of treating physicians are important in analyzing Vaccine Act cases and must be considered.
Andreu, 569 F.3d at 1375.

                                                   42
from February 24, 2011, during which Petitioner called Dr. Sy for an ENT referral, and (2) a record
from Petitioner’s hospitalization on April 25, 2012, which purportedly “documents [Petitioner’s]
symptoms as starting 2 weeks after the Gardasil vaccine was given.” Id.

         For one, I note that Dr. Sy did not set forth in her written opinion any detailed explanation
concerning why she believes that Petitioner’s call for a referral to an ENT specialist marked the
start of her symptoms. Second, as I note at footnote 38, above, an examination of the entirety of
Petitioner’s emergency department records starting on April 25, 2012 offer a different accounting
of the start of her symptoms, as reported by Petitioner at that time. Those records reflect that
Petitioner reported she “was in her usual state of health up until 1 year ago when she started
developing BLE [bilateral lower extremity] numbness and tingling.” Ex. 33-1 at 1; see also Ex.
33-1 at 41-43. Third, in direct contravention of Dr. Sy’s onset statements in Ex. 32, even
Petitioner’s own expert, Dr. Steinman, does not opine in his expert reports that Petitioner’s onset
of MS started as early as a few weeks after Petitioner’s HPV vaccination of January 19, 2011. See
Ex. 35 at 1 (Dr. Steinman stating that Petitioner’s onset of clinical symptoms of MS “began no
earlier than mid-April 2011.”); see also generally Exs. 35, 40, 42, 44, 46-47 (reflecting Dr.
Steinman’s first through sixth expert reports).

        While I have given Dr. Sy’s opinion letter careful consideration, in my final analysis, I find
that her opinion is strongly outweighed by the rest of the evidence in the record concerning the
onset issue, particularly the medical record evidence, the brain MRI results in April 2011 reflecting
no demyelinating lesions (see Ex. 2 at 15-16), the thoracic and cervical spine MRI results in July
2011 also reflecting no demyelinating lesions (see Ex. 2 at 31 and Ex. 13 at 5-6), the
contemporaneous assessments of Petitioner’s treating physicians in the weeks and months after
Petitioner’s HPV vaccination, and the testimony of Dr. Tenser.

               2. Petitioner’s Onset of MS Was in Late March 2012

       Upon my own close examination of the medical records, I find that Petitioner’s medical
condition drastically deteriorated over a short time period, starting in late-March 2012 to April 26,
2012, the date of her cervical spine MRI and brain MRI revealing findings worrisome/suspicious
for demyelination. See Petitioner’s relevant medical history from January 2012 through April
2012 discussed at Section II(A)(3).

                       a. Relevant Medical History from Late March to Late April 2012

       Petitioner visited Dr. Wang on March 27, 2012, for complaints of headaches. Ex. 13 at 17-
19. Dr. Wang noted that Petitioner has a medical history of lupus, and recorded Petitioner’s
descriptions of her headaches, which she described as causing “tingling and numbness in her
extremities with her headache.” Id. at 17. Upon examination, she was assessed as having “basilar
migraine.” Id. at 19.

       Petitioner again visited Dr. Wang for her headaches on April 16, 2012. At that time, she
reported that she was “having a new concern with numbness and tingling to the upper and lower
extremities,” which Dr. Wang deemed as being “consistent with peripheral neuropathy for upper
and lower extremities.” Ex. 13 at 15. Dr. Wang ordered additional testing to rule out certain

                                                 43
disorders, including electromyography (EMG) and nerve conduction velocity study (NCS) of the
upper and lower extremities, and an MRI of the brain. Id. Petitioner had her EMG and NCS study
done on April 23, 2012, which yielded normal results. Id. at 7.

        On April 24, 2012, Petitioner presented for her consultation with Dr. Posner as a
wheelchair-bound patient. Ex. 4 at 1. Dr. Posner noted that Petitioner “was last evaluated in this
office on February 13, 2012 and her clinical condition has changed radically since that visit.” Id.
Upon examination, Dr. Posner noted that Petitioner’s exam was “noteworthy for a disassociation
between [her] affect being somewhat lighthearted compared to the profound motor difficulty” that
she was experiencing at that time, especially in light of the fact that Petitioner was experiencing
those symptoms “without obvious localizing neurologic signs.” Id.

        Petitioner presented to St. Joseph’s Hospital’s emergency department on April 25, 2012,
being admitted to the neurology service with complaints of continued worsening of paresthesia
and weakness in her bilateral lower extremity (“BLE”) for the past month. Ex. 33-1 at 1. At that
time, Petitioner reported that she “was in her usual state of health up until 1 year ago when she
started developing BLE numbness and tingling.” Id. Additional examinations were ordered to
properly assess her care. Id. at 3.

       Petitioner underwent an MRI of her cervical spine on April 26, 2012, which her
neuroradiologist interpreted as reflecting “[f]indings worrisome for demyelination.” Ex. 2 at 9. On
that same date, Petitioner also underwent an MRI of her lumbar and thoracic spine, which both
revealed unremarkable results. Id. at 11-12. She similarly underwent a brain MRI with contrast,
the results of which were interpreted by her treating neuroradiologist as being “suspicious for
demyelination.” Id. at 13. A multiple sclerosis (MS) panel was tested on April 25, 2012; both the
IgG index and the oligoclonal band study were listed as QNS.78 Ex. 33-1 at 24.

                       b. Summary of My Finding

        While the question of Petitioner’s MS onset is not entirely straightforward in this case, I
find that a preponderance of the evidence supports onset in March 2012 as opposed to April 2011.
Upon analyzing the entire record of this case, with particular study devoted to the records above,
Petitioner’s complaints on April 25, 2012, of continued worsening of paresthesia and weakness in
her BLE for the past month, puts Petitioner’s onset of her MS symptoms around March 25, 2012.
This finding is supported by a contextual analysis of Petitioner’s visit with Dr. Wang on April 16,
2012, at which time she reported that she was “having a new concern with numbness and tingling
to the upper and lower extremities.” Ex. 13 at 15, emphasis added. In this regard, I also find Dr.
Tenser’s opinion on this issue to be persuasive in explaining that the combination of: (1) clinically
apparent leg numbness and weakness noted in her medical records; (2) her April 2012 brain MRI
reflecting abnormal and enhanced multiple white matter abnormalities; and (3) her April 2012

78
  Petitioner’s medical records reflect that she was clinically diagnosed with MS by a Barrow
NeuroImmunology neurologist on October 30, 2012, at which time Petitioner was noted to meet the 2010
McDonald’s Criteria for MS based on her clinical history and radiologic progression. See Ex. 9 at 20.

                                                 44
abnormal cervical spinal cord MRI reflecting several lesions enhanced, in the aggregate, point
towards Petitioner’s onset of MS being sometime in the “spring of 2012.” Ex. C at 4.

        C. The Onset of Petitioner’s Symptoms Did Not Occur in a Medically Acceptable
           Timeframe (Althen Prong Three)

       More than a year passed from the date Petitioner received her HPV vaccination on January
19, 2011, to the onset of her MS symptoms around March 25, 2012. That timeframe from
vaccination to onset is entirely too long. Even Dr. Steinman does not opine that onset of MS can
occur outside the timeframe of mid-April 2011, much less more than a year after vaccination.
Thus, I find Dr. Tenser’s opinion (see discussion above at Section IV(B)(1)(b)(iii)) and Dr.
Schroeder’s opinion (see discussion at Section IV(B)(2)(b)(iii)) on this issue to be more
persuasive, as compared to Dr. Steinman’s opinion on this issue (see discussion above at Section
IV(A)(2)(b)(iii).

       Petitioner’s medical history starting from mid-April 2011 also factors into my analysis.
Specifically, I find Dr. Schroeder’s position on this issue to be persuasive when he opines that a
temporal association between Petitioner’s HPV vaccination and the onset of her MS is further
unlikely due to Petitioner’s intervening history of Lyme Disease, Lupus, and Sjögren’s syndrome.
See Dr. Schroeder’s discussion above at Section IV(B)(2)(b)(iii) and Ex. P at 8.

         In the alternative, I note that even if I were to assume that the date of onset for Petitioner’s
MS symptoms is in mid-April 2011 (April 14, 2011), 86 days after she received her HPV vaccine,
I still am not persuaded by Dr. Steinman’s opinion that an almost three-month timeframe between
Petitioner’s HPV vaccination and the onset of MS is medically appropriate. I reiterate that the
majority of Dr. Steinman’s discussion regarding the basis of his timing opinion is of limited
persuasive value, and serves to confound the issues when his explanations veer into discussions of
questionable relevance.

        I extensively discuss, in Section IV(A)(2)(b)(iii) above, the ways in which I find Dr.
Steinman’s timing opinion to be unpersuasive. My reasons include: (1) Dr. Steinman’s propensity
to improperly analogize study findings relating to different vaccines and different non-
demyelinating diseases to his timing opinion in this case, without providing a cogent explanation
as to how or why any of those studies can be analogized here; (2) his overstating the strength of
certain literature as supportive of his position; (3) his veering into discussions of limited relevancy
in his expert report, including providing his own legal opinion as to the appropriate standard in
Vaccine Act cases; and (4) his selecting results from a study that supports his position, while
ignoring the overall finding of that study. In short, Dr. Steinman’s opinion on this issue lacks the
foundational basis to explain how the HPV vaccination can trigger Petitioner’s onset of MS three
months after her vaccination.

          In contrast, I find Dr. Tenser’s opinion that, even assuming Petitioner’s onset of MS was
in mid-April 2011, as opined by Dr. Steinman, onset approximately ninety days from vaccination,
is still “too long,” by Dr. Steinman’s own research that he submits as supportive of his opinion in
this case. See discussion of Dr. Tenser’s opinion regarding the appropriate temporal association
at Section IV(B)(1)(b)(iii), above.

                                                   45
        Furthermore, while I have carefully evaluated the specific arguments advanced by Dr.
Steinman in this case, I generally note that special masters in the Program have consistently found
the onset of demyelinating diseases to be temporally appropriate if symptoms begin within (but
not after) eight weeks of vaccination.79

        D. Remaining Althen Prongs

        Because this claim can be resolved based on one of the Althen prongs, substantial additional
discussion of the remaining two prongs is unnecessary. See, e.g., Lasnetski v. Sec’y of Health &
Human Servs., 128 Fed. Cl. 242, 264 (2016), aff’d, 696 F. App’x 497 (Fed. Cir. 2017) (not error
for special master to forego Althen analysis after determining that a petitioner had not in fact
experienced the disease or illness alleged to have been vaccine-caused). I will, however, briefly
note the following points relevant to the complete analysis. Petitioner’s showing on the “can
cause,” first prong -- that the HPV vaccine can cause MS -- has both scientific reasonableness and
plausibility, and was effectively supported by the literature filed as well as expert opinion offered.
Dr. Steinman’s expertise with central nervous system disorders and the field of immunology
renders him well qualified to opine on the causal potential of vaccines in producing MS. There
are also instances in the Vaccine Program in which other special masters have determined that a
petitioner successfully established a plausible causation theory involving the capacity of different

Giannetta, 2017 WL 4249946.

        At the same time, Respondent identifies weaknesses in the causation theory. In particular,
Dr. Tenser offers compelling testimony that calls into question the extent of reliable scientific
proof offered by Dr. Steinman to explain how Gardasil can cause MS in general. Dr. Tenser also
points to epidemiological studies that examined the association between vaccinations and MS, and
the association between the HPV vaccine and MS, as undercutting Dr. Steinman’s general
causation theory in this case. Because the case decisively turns on onset and timing, I need not
decide conclusively if Petitioner carried her burden on this component of the Althen test -- although
to the extent the evidence presented on this aspect of Petitioner’s burden was close, I would
necessarily have to decide it in Petitioner’s favor. See Althen, 418 F.3d at 1280.

        With regard to the second, “did cause,” Althen prong, however several significant problems
arise in the proof that lead me to state more unequivocally that Petitioner has not met this part of
her evidentiary burden. First, Dr. Steinman provides a cursory discussion as to his specific
causation opinion in this case -- i.e., whether the HPV vaccination received by Petitioner on
January 19, 2011 did cause her MS. While Dr. Steinman states that conclusion, he provides little
analysis as to why that might be so in this case. The extent of his analysis rests on his own
assertions that he conducted an analysis of the Gardasil package insert to reach his specific
causation opinion. But he fails to provide any further elaboration of what exactly the analysis was
that he conducted while examining the contents of that package.

        Furthermore, the records from Petitioner’s contemporaneous treatment providers do not
support a causal link between the HPV vaccination and Petitioner’s MS. See Section II(A)(2)-(4),
above. My finding in this regard is further supported by my Althen prong three analysis; because
the time between vaccination and onset of MS symptoms is not medically appropriate, I do not
find that the vaccine did cause Petitioner’s MS.

     VII. CONCLUSION

        Petitioner has unquestionably suffered a life-altering injury, and the affidavits credibly
establish the suffering she and her family have experienced in its aftermath. But the Vaccine Act
permits me to award compensation only if a Petitioner alleging a “non-Table Injury” can show by
medical records or competent medical opinion that the injury was more likely than not vaccine-
caused. In this case, the evidence advanced by Petitioner has fallen short of demonstrating such a
link. Accordingly, I conclude that Petitioner in this case is not entitled to a Program award.80
