                                                 1
acellular-Pertussis (“DTaP”), haemophilus influenzae type B (“HiB”), pneumococcal conjugate
(“PCV”), and rotavirus vaccines on April 8, 2009 caused L.J.’s death. Am. Pet., April 3, 2012,
at 1. For the reasons set forth below, the undersigned concludes that Petitioners are not entitled
to an award.

    I.     FACTS

         L.J. was born on February 7, 2009 at 40 weeks gestational age, the product of an
uncomplicated pregnancy. 3 Pet. Ex. 1 at 114; Pet. Ex. 3 at 4, 13. At birth, her APGAR scores
were 9 and 9. Pet. Ex. 1 at 114. She was administered her first Hep B vaccination the day after
her birth, Pet. Ex. 4 at 33, and was noted to have had normal growth and development during her
first few months of life.

        L.J. was seen by her pediatrician, Dr. Keith Boykin, on February 9, 2009 and February
27, 2009. Pet. Ex. 4 at 11-14, 20-22. At her two-day visit on February 9th, Mrs. Jewell reported
that L.J. slept on her back; at her 20-day visit, L.J. slept on her “back and side.” Id. at 12, 21. At
both visits, L.J. was noted to have had good health and normal behavior. Id. at 8, 12-13, 21-22;
Pet. Ex. 9 at 1.

        On April 8, 2009, at her two-month well-child check-up, L.J. was administered her
second dose of the Hep B vaccine and her first doses of the DTaP, IPV, HiB, PCV, and RV
vaccines. Pet. Ex. 4 at 4, 7-9; Pet. Ex. 5 at 1. The vaccines were administered at approximately
1:50 p.m. Pet. Ex. 4 at 6; Pet. Ex. 7 at 6. During the visit, L.J.’s pediatrician again noted that she
was healthy and behaving normally. Pet. Ex. 7 at 7-8; see also Pet. Ex. 7 at 4 (L.J.’s pediatrician
reporting to law enforcement after her death that she “had never been sick, and she was a healthy
baby.”).

        L.J.’s medical records are ambiguous regarding the nature and extent of her symptoms
during the afternoon and evening following vaccination. According to Mr. Jewell’s affidavit,
“that night, [L.J.] was fussy and did not eat much.” Pet. Ex. 9 at 1-2. According to the April 9,
2009 police report that was completed after L.J.’s death, Mr. Jewell told responding officers that
L.J. “was fine when they put her to bed,” though she was “crying a little more than usual” and
“didn’t want to take her bottle.” Pet. Ex. 7 at 4. Mrs. Jewell reported to the officers that “after
the Dr’s appt [sic] she and her husband met up and had dinner with [L.J.’s sister, E.J.] and [L.J.].
Lindsey slept after shots and slept through dinner and the car ride home.” Id. at 7.

3
 Mrs. Jewell and L.J. were noted to have had an Rh incompatibility: Mrs. Jewell was B and RH
negative; L.J. was AB and RH positive. Pet. Ex. 4 at 21. L.H. was identified as “Coomb’s
positive.” Id.

                                                  2
        There is no dispute that L.J. was afebrile and “was fine” when she was put to sleep in to
her crib at approximately 9:45 or 10 p.m. on the day of vaccination. Pet. Ex. 7 at 3-4, 7.
According to Mrs. Jewell’s statements to law enforcement, L.J. “whined and cried a little bit for
about 15 minutes however finally went to sleep.” Id. at 7. Mrs. Jewell reported that, at bedtime,
L.J. “only took 3 oz of formula and was not super cranky but was a little irritable and
whimpering.” Id. 4 At 10 p.m., Mrs. Jewell reported, she heard L.J. breathing and noted that she
“seemed to be just fine.” Id. Mrs. Jewell also reported that L.J. “had started rolling on her side
and would end up on her tummy so she put a little body bumper in the crib which kept [L.J.]
from rolling over on her tummy.” Id.

        Mrs. Jewell woke up at approximately 10 a.m. the following morning and became
concerned that she hadn’t heard any noises on L.J.’s baby monitor. Pet. Ex. 7 at 7. She “went
into the babies room [sic] and rubbed the top of [L.J.’s] head and saw that she looked purple and
she felt like something was wrong.” Id. “Mrs. Jewell said that [L.J.] felt slightly warm.” Id. at
7-8. Mrs. Jewell called 911, and responding personnel discovered L.J. “laying on her right side,”
with both a white swaddle and a pink blanket “wrapped around her.” Id. at 3. When the
responding officers asked Mrs. Jewell whether this was the position that L.J. was in when she
came in to the room, Mrs. Jewell responded that “it was,” though she had taken L.J. out of the
crib to attempt CPR before replacing her, apparently in the same position. Id. Mrs. Jewell also
stated that she “had the baby in a onesie and swaddled in a blanket that has butterfly type wings
that wrap around the baby and she also had a blanket around the baby.” Id. at 8. L.J. was
pronounced Dead On Arrival (“DOA”) by Fire and Rescue personnel at 10:15 a.m. Id. at 3.

        According to the report from an autopsy conducted on April 10, 2009, L.J.’s cause of
death was Sudden Infant Death Syndrome. Pet. Ex. 6 at 4-7. There was evidence of pulmonary
and thymic petechiae consistent with a pathological SIDS diagnosis, but there was no evidence
of “trauma, disease, or congenital anomaly.” Id. The autopsy revealed petechial hemorrhages
under the pleura of each lung and in the thymus, lungs that were congested and slightly heavy
(65 g right, 55 g left), and a slightly heavy brain (583 g). Id. A toxicology screen, a virology
culture, influenza PCR, and antibodies of blood and spinal fluid were negative. Id. The autopsy
report documented that L.J. had been found by her mother “dead in her crib, on her back, slightly
on her right side, in the same position in which she had been placed down to sleep.” Pet Ex. 6 at
6.

    II.    PROCEDURAL HISTORY

       Although Petitioners were pro se when they filed their original petition, they immediately
expressed an interest in retaining counsel. See Scheduling Orders filed April 13, 2011; June 23,

4
  The record does not contain an affidavit authored by Mrs. Jewell. All of her statements were
reported to responding officers and law enforcement personnel.

                                                3
2011; July 19, 2011. On August 8, 2011, Ronald Homer filed a consented motion to substitute
himself as attorney of record. Petitioners filed eight medical record and other exhibits on
October 3 and 4, 2011, and a statement of completion on December 15, 2011. See Pet. Exs. 1-8.

        On February 22, 2012, Respondent filed a Rule 4(c) Report in which she argued that
Petitioners are not entitled to compensation for L.J.’s allegedly vaccine-caused death because
they had not presented any evidence of a Vaccine Table injury, and because they had failed to
articulate a causal theory by which the administered vaccines had caused her death. Resp. Rep.
at 5-6. Respondent pointed out that none of L.J.’s treating physicians attributed her death to her
vaccinations, and she argued that the cause of L.J.’s death, SIDS, is, by definition, unrelated to
vaccination. Id. at 6-8.

        Petitioners filed an amended petition, as well as an affidavit authored by Mr. Jewell, on
April 3, 2012. See Pet. Ex. 9.

        On November 6, 2012, Petitioners filed an expert report authored by Dr. Douglas Miller,
M.D., with referenced medical literature and Dr. Miller’s curriculum vitae (“CV”). Pet. Exs. 11
(expert report), 13-35 (medical literature), 12 (CV). On May 17, 2013, Respondent filed expert
reports authored by Dr. Lucy B. Rorke-Adams., M.D., and Dr. Christine McCusker, M.D. Pet.
Exs. A (Dr. Rorke-Adams’ report), B (Dr. Rorke-Adams’ CV); C (Dr. McCusker’s report), D
(Dr. McCusker’s CV), E1-E17 (Dr. McCusker’s medical literature). Petitioners filed a
supplemental expert report authored by Dr. James Oleske on December 11, 2013. Pet. Ex. 36;
see also Pet. Ex. 37 (Dr. Oleske’s CV). Respondent filed a responsive expert report authored by
Dr. McCusker on February 10, 2014. See Pet. Ex. F.

        The undersigned subsequently scheduled an evidentiary hearing on the issue of vaccine
causation. Petitioners filed pre-hearing submissions on April 24, 2014; Respondent filed pre-
hearing submissions on May 15, 2014 and June 12, 2014. The entitlement hearing was held in
Washington, DC on June 26-27, 2014. See Transcript of Proceedings (“Tr.”). The parties filed
simultaneous post-hearing briefs on August 22, 2014. The matter is now ripe for a decision on
entitlement.

   III.      ANALYSIS

          A. Standards of Adjudication

         To receive compensation under the Vaccine Act, Petitioner must demonstrate either that:
(1) she suffered a “Table injury” by receiving a covered vaccine and subsequently developing a
listed injury within the time frame prescribed by the Vaccine Injury Table set forth at 42 U.S.C.
§ 300aa-14, as amended by 42 C.F.R. § 100.3; or (2) that she suffered an “off-Table Injury,” one
not listed on the Table as a result of her receipt of a covered vaccine. See 42 U.S.C. §§ 300aa-
11(c)(1)(C); Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1321 (Fed. Cir. 2010);
Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317, 1320 (Fed. Cir. 2006).

                                                 4
        Because Petitioner does not allege a Table injury in this case, she must prove that her
injury was caused-in-fact by an on-Table vaccine. To establish causation-in-fact, Petitioner must
demonstrate by a preponderance of the evidence that the vaccine was the cause of the injury.
42 U.S.C. § 300aa-13(a)(1)(A). Petitioners are required to prove that the vaccine was “not only
[the] but-for cause of the injury but also a substantial factor in bringing about the injury.”
Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1321-22 (Fed. Cir. 2010) (quoting
Shyface v. Sec’y of Health & Human Servs., 165 F.3d 1344, 1352-53 (Fed. Cir. 1999)).

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

         Specifically, under the first prong of Althen, Petitioners must offer a scientific or medical
theory that answers in the affirmative the question “can the vaccine(s) at issue cause the type of
injury alleged?” See Pafford v. Sec’y of Health & Human Servs., No. 01-0165V, 2004 WL
1717359, at *4 (Fed. Cl. Spec. Mstr. July 16, 2004). This may be accomplished in a number of
ways. Id. “Reliability and plausibility of pathogenesis can be bolstered by providing evidence
that at least a sufficient minority in the medical community has accepted the theory, so as to
render it credible.” Id. In addition, epidemiological studies and an expert’s experience, while
not dispositive, lend significant credence to the claim of reliability; articles published in
respected medical journals, which have been subjected to peer review, are also persuasive. Id.
However, publication “does not necessarily correlate with reliability,” because “in some
instances well-grounded but innovative theories will not have been published.” Daubert v.
Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 593–94 (1993).

        In addition to showing that the vaccine at issue can cause a particular injury, a petitioner
must also prove that the vaccine actually did cause the alleged injury in a particular case. See
Pafford, 2004 WL 1717359, at *4 (emphasis added); Althen, 418 F.3d at 1279. A petitioner does
not meet this obligation by showing only a temporal association between the vaccination and the
injury; the petitioner must explain “how and why the injury occurred.” Pafford, 2004 WL
1717359, at *4.

       While a temporal association alone is insufficient to establish causation under the third
prong of Althen, a petitioner must show that the timing of the injury fits with the causal theory.
See Althen, 418 F.3d at 1278. For example, if the petitioner’s theory involves a process that

                                                  5
takes several days to develop after vaccination, an injury that occurred within a day of
vaccination would not be temporally consistent with that theory. Conversely, if the theory is one
that anticipates a rapid development of the reaction post-vaccination, the development of the
alleged injury weeks or months post-vaccination would not be consistent with that theory. The
special master cannot infer causation from temporal proximity alone. In fact, it has been held,
that where a petitioner's expert views the temporal relationship as the “key” indicator of
causation, the claim must fail. See Thibaudeau v. Sec’y of Health & Human Servs., 24 Cl. Ct.
400, 403-04 (Fed. Cl. Oct. 23, 1991); see also Grant v. Sec’y of Health & Human Servs., 956
F.2d 1144, 1148 (Fed. Cir. 1992); Hasler v. United States, 718 F.2d 202, 205 (6th Cir. 1983)
(stating that inoculation is not the cause of every event that occurs within a ten-day period
following it).

        A petitioner who demonstrates by a preponderance of the evidence that he suffered an
injury caused by vaccination is entitled to compensation, unless the respondent can demonstrate
by a preponderance of the evidence that the injury was caused by factors unrelated to the
vaccination. See Althen, 418 F.3d at 1278; Knudsen v. Sec’y of Health & Human Servs., 35 F.3d
543, 547 (Fed. Cir. 1994).

       B. The Parties’ Arguments

               a. Petitioners’ Arguments

                       i. Dr. Douglas Miller

                              1. Qualifications

        Dr. Miller received his doctorate in medicine from the University of Miami School of
Medicine and completed two residencies in anatomic pathology and neuropathology at the
Massachusetts General Hospital and at Harvard Medical School. Pet. Ex. 12; Tr. 395. He also
received a PhD in physiology and biophysics, having studied “nerve physiology [and] …
mechanisms of synaptic transition between nerves and nerve cells.” Tr. 394-95. He has served
as a Faculty Fellow at the University of Pennsylvania School of Medicine, Center for Clinical
Epidemiology and Biostatistics, and was additionally a Fellow in the Division of Rheumatology.
Id. He currently teaches at the University of Missouri School of Medicine, works as an attending
pathologist at the University, and is an associate medical examiner. Tr. 398.

      At hearing, the undersigned admitted Dr. Miller as an expert in neuropathology and
anatomic pathology. Tr. 400.

                                                6
                              2. Theory

        At hearing and in his expert reports, Dr. Miller argued that vaccines are capable of
causing SIDS in vulnerable infants, and that such deaths occur in a manner consistent with an
established model – called the “Triple Risk Model” – of SIDS risk factors and vulnerabilities.
See Pet. Ex. 14 5 at 2-3. According to the Triple Risk Model, which was postulated by Dr.
Hannah Kinney, infants are particularly susceptible to SIDS when three conditions are met: 1)
the infant is in a critical developmental period, i.e., between one and twelve months of life, with
peak risk occurring between two and four months; 2) the infant has inherent brainstem
abnormalities – also referred to herein as 5-HT system 6 defects, or serotonin defects – which lead
to deficiencies in serotonin-mediated synaptic activity; and 3) the infant is subject to an
environmental factor, also known as an “exogenous stressor,” such as a prone sleeping position,
an upper respiratory infection (“URI”), or an excessively warm sleeping environment. Pet. Ex.
11 at 3-4; Tr. 418-20; Filiano at 2-3. Dr. Miller theorized that vaccinations, by design, are
capable of triggering “systemic cytokine release and cytokine-mediated abnormal brainstem
responses,” and that this cytokine activity, when “acte[ing] in a brainstem … already deficient in
serotonergic drive for respiratory effort, [can] lead[] to an apneic 7 episode from which [the
patient] d[oes] not recover, i.e. SIDS.” Pet. Ex. 11 at 5.

Infant Death Syndrome: The Triple-Risk Model, Biol. Neonate, 1994; 65: 194-97 [hereinafter
Filiano].

6
  Dr. McCusker described the function of the 5-HT system as “regulat[ion of] sleep and arousal
patterns.” Tr. 240. She explained that “there is development of this system as you age:” “the
sleep system has a maturational component and that … maturity occurs from gestational age,
second trimester … through to ten months.” Id. Dr. Miller testified that 5-HT is a
neurotransmitter, and that it is “involved in the sensing of CO2 levels and in stimulating
respiratory drive to produce arousal and breathing in the setting of excess CO2 in the
bloodstream.” Tr. 425-26. 5-HT system defects are present at birth. Tr. 411. Functionally
speaking, the 5-HT system is “one of the main components of the human CO2[-]sensing sleep
arousal system;” “one of its important functions is to cause arousal and stimulate breathing in a
situation where the CO2 levels in the blood rise above some threshold.” Tr. 413.

Throughout this decision, the undersigned will use the terms “5-HT system” and “serotonergic
system” interchangeably.

 “Apnea” or “apneic” refers to “the cessation of breathing.” Dorland’s Illustrated Medical
Dictionary (Dorland’s), 116 (32nd. Ed. 2012).

                                                7
         Dr. Miller, who agreed with L.J.’s medical examiner that her death was attributable to
SIDS, noted that L.J.’s autopsy slides “suggest[] the presence of … hypoplasia of the arcuate
nuclei, 8” an abnormality present in many cases of SIDS, consistent with the second condition of
Dr. Kinney’s Triple Risk Model. Tr. 416, Pet. Ex. 11 at 3-4. Citing Dr. Kinney’s studies, Dr.
Miller explained that the ventral arcuate nuclei of the medulla, which, as the lowest part of the
brainstem, is “responsible for the initiation and regulation of muscle efforts underlying
breathing,” are defective in many SIDS cases. Id. at 3-4; Pet. Ex. 189; Pet. Ex. 2010 (“[T]he most
robust neurochemical abnormality in SIDS involves the medullary 5-HT system [], which is
involved in approximately 70% of SIDS deaths”); Tr. 452-54. According to Dr. Miller, “there’s
a reasonable probability that [L.J.] had a defective arcuate nucleus,” and that her death resulted
from “failed mechanisms of arousal and inadequate reactions to apneic episodes during sleep.”
Pet. Ex. 11 at 3-4; Tr. 451. Dr. Miller testified that he had never seen hypoplasia or aplasia of
the arcuate nucleus in a non-SIDS case. Tr. 413.

         Even if L.J. did not have a defective arcuate nucleus, see p. 9, infra, Dr. Miller’s opinion
is that the vaccines she received on April 8, 2009 were a “substantial contributing factor” to her
death. Tr. 494. Dr. Miller explained that, because the literature suggests that most SIDS cases
are attributable in part to defective 5-HT systems, it is likely that L.J.’s 5-HT system was
defective, making her vulnerable to exogenous stressors. 5-HT neurons are designed to increase
their firing in response to increased levels of carbon dioxide, which leads to more active
breathing and arousal, so that the body doesn’t die of apnea. Tr. 426-29. A 5-HT system that is
defective, either by virtue of hypoplasia 11 (or aplasia 12) of the arcuate nuclei or by virtue of a

8
  Arcuate nucleus of medulla oblongata is “one of the group of small, irregular areas of gray
substance found on the ventromedial aspect of the pyramid of the medulla oblongata.”
Dorland’s, 1295. Studies have shown that “in a subset of babies who had died of what appeared
to be SIDS … the arcuate nucleus was either completely missing on both sides or was much
smaller than comparable controls.” Tr. 412-13.

   Hypoplasia is defined as “incomplete development or underdevelopment of an organ or tissue;
it is less severe in degree than aplasia.” Dorland’s, 905.

     Aplasia is defined as “lack of development of an organ or tissue.” Dorland’s, 116.

related abnormality, is impaired in its ability to monitor carbon dioxide levels in the body. Tr.
429-30. Vaccines, Dr. Miller argued, may serve as an exogenous stressor 13 by depressing the
activity of 5-HT neurons in an already defective system. Tr. 439. By prompting the activity of
certain cytokines that are known to reduce the activity of serotonergic neurons – namely, IL-1,
IL-6, and IL-2 – the vaccination, Dr. Miller theorized, prevents an already-defective system from
stimulating respiration. Tr. 469-70.

        At hearing, Dr. Miller explained why, according to the Kinney model and his own theory,
cytokine activity induced by inflammation in the body’s periphery would be capable of
depressing arousal even in a dysfunctional 5-HT system. Tr. 405-11; but see Tr. 337-40 (Dr.
McCusker, Respondent’s expert, testifying that an infant’s defective 5-HT system prevents the
system from receiving signals from cytokines, and thereby prevents vaccination-induced
cytokine activity from depressing the 5-HT system’s arousal function); see also Pet. Ex. 2514
(explaining how IL-1 inhibits the firing of serotonergic neurons). Dr. Miller explained that a
dysfunctional 5-HT system as described by Dr. Kinney is not completely absent; rather, it is
simply reduced in terms of neurons and functionality: “when … IL-1 gets into the nervous
system to act on reducing 5-HT activity, in a normal child, that reduction will be inconsequential
because there’s plenty of 5-HT neurons there. But in a child with far fewer 5-HT neurons, that
could then become critical.” Tr. 406. Dr. Miller testified that he has never seen an autopsy
which showed the complete absence of all 5-HT neurons from the medulla. Id. Even if the
number of receptor molecules is so reduced that it can’t sense carbon dioxide, “there’s nothing to
suggest that the individual receptor molecules are defective …. [i]t’s a cellular level problem, not
a membrane or a protein level problem.” Tr. 408.

        In support of his theory, Dr. Miller pointed to neuropathological evidence in the record;
namely, L.J.’s autopsy slides. Tr. 411-12. The four slides reviewed by Dr. Miller contained a
piece from two sides of one “level” of the medulla of L.J’s brain. Tr. 421-25. Based on his
review, Dr. Miller concluded that there was “hypoplasia and aplasia” of an arcuate nucleus in
L.J.’s case. Id. However, when asked whether Dr. Kinney would be likely to concur with this
pathological finding, Dr. Miller clarified that

       reporting as a pathologist, she would likely say that the evidence is inadequate
       because [the slides contain] only one level [of the medulla,] and she has written

13
  Dr. Miller acknowledged that Dr. Kinney has never described vaccines as a potential
exogenous stressor in her model. Tr. 443.

14
  Brambilla, D., et al., Interleukin-1 inhibits firing of serotonergic neurons in the dorsal raphe
nucleus and enhances GABAergic inhibitory post-synaptic potentials, Eur. J. Neuroscie, 2007;
26: 1862-69 [hereinafter Brambilla].

                                                 9
       extensively that one should serially block the medulla and put through all the
       levels. She’s described very carefully that …. One can see almost no arcuate
       nucleus and then at another level see a perfectly adequate one.

Tr. 450. In light of the fact that he was unable to review “all the levels of the medulla,” Dr.
Miller testified that he was unable to “diagnose,” or to make a “pathological finding,” that L.J.
had a defective arcuate nucleus; rather, he found only a “reasonable probability” that her arcuate
nuclei were defective. Tr. 450-51. He also testified that his findings regarding L.J.’s arcuate
nucleus are “well short of diagnostic or even more probable than not.” Tr. 463. He reiterated,
however, that regardless of the deficiencies inherent in the slides, he would argue in favor of
vaccine causation because, whether or not L.J.’s arcuate nuclei were compromised, she likely
had “a defective brainstem serotonergic system.” Tr. 482-83, 463, Kinney 2 (concluding that
70% of cases thoroughly studied have a defect in the 5-HT system).

        Dr. Miller conceded that several of Dr. Kinney’s identified exogenous stressors may have
been at play in L.J.’s case. He agreed that the autopsy findings suggest that L.J. “was at least
partially on her right side” at the time of death, though he also opined that it is impossible to
know in “what position she really was lying.” Tr. 476-77. He also acknowledged that L.J. was
potentially subject to an excessively warm sleeping environment because she was swaddled and
wrapped in an additional blanket. Tr. 479, 481. He argued, however, that these factors are not as
likely to have constituted the sole exogenous stressors – to the exclusion of vaccine-induced
cytokine activity – in L.J.’s case. Tr. 483-84. Dr. Miller testified that the other potentially
relevant exogenous factors 1) are “not backed by very much in the way of statistically valid
evidence or epidemiology, but more by anecdote,” and 2) “didn’t strike [him] as significant” in
L.J.’s case. Tr. 483-84. Dr. Miller did not rule out the possibility that, if other exogenous
stressors were at play in L.J.’s case, they worked “synergistically” with vaccine-induced
cytokine activity to cause her SIDS. Tr. 484.

        Mr. Miller agreed that there is a dearth of epidemiology conclusively establishing a
relationship between vaccination and SIDS. Tr. 439-40. He explained this phenomenon by
pointing out that, although the population of vaccinated infants is very large, the percentage of
that population that is neuropathologically vulnerable is very small. 15 Tr. 439-40. Dr. Miller
pointed out that there is literature in support of his argument that specific cytokines are capable
of impacting the 5-HT system, that the identified cytokines have been found in the serotonergic
system of the medulla in SIDS cases, and that multiple stressors may work synergistically to
cause SIDS. Tr. 486-91; see also Brambilla, Rognum. Addressing the Vennemann article, which

15
  Dr. Miller did not explain why this fact – i.e., the fact that the population of identified
neuropathologically vulnerable infants is small – does not undermine Dr. Kinney’s theory that
neuropathological defects are a risk factor for SIDS. The population was large enough for Dr.
Kinney to identify a correlation on its basis.

                                                10
reported on a large case control study from Germany that found no association between
vaccination and SIDS, Dr. Miller argued that the “vulnerable” population had not been
accurately identified, because autopsies were performed by forensic pathologists, not
neuropathologists, and because the study does not explain exactly what was examined in
subjects’ brains. Tr. 440-41; Resp. Ex. E16 16. Dr. Miller also argued that the Vennemann
authors’ scientific methodology was insufficiently rigorous. Tr. 441.

                       ii. Dr. James Oleske

                               1. Qualifications

        Dr. Oleske graduated from New Jersey Medical School and received a Masters in Public
Health from the Columbia University School of Public Health. Pet. Ex. 37; Tr. 12. After
completing a fellowship in “allergy/ immunology/ infectious disease,” Dr. Oleske became a
faculty member at the New Jersey Medical School, where he is currently the Director of the
Division of Pediatric Allergy, Immunology, and Infectious Diseases. Tr. 13. Dr. Oleske has
conducted extensive research on the immune system and immune responses, and is board
certified in pediatrics, allergy, immunology, pediatric infectious diseases, and pediatric palliative
end-of-life care. Tr. 15-16.

       At hearing, the undersigned admitted Dr. Oleske as an expert in allergy, immunology,
and infectious disease. Tr. 18.

                               2. Theory

        Dr. Oleske, like Dr. Miller, has incorporated Dr. Kinney’s Triple Risk Model in to his
theory of causation. Pet. Ex. 36 at 2; Tr. 53-57. Dr. Oleske explained that, according to Dr.
Kinney’s model, “extrinsic and intrinsic risk factors converge” to prevent infants’ brains from
being able to “adequately control postnatal homeostasis,” resulting in SIDS death. Id.
According to his theory, the minor infection caused by vaccination – which he also refers to as
an “inflammatory process” 17 – may function as the “exogenous stressor” in Dr. Kinney’s model.
Tr. 49-50, 52-53 (L.J.’s SIDS “more likely than not” resulted from an inflammatory response,

16
 Vennemann, M., et al., Sudden infant death syndrome: no increased risk after immunization,
Vaccine, 2007; 25(2): 336-40 [hereinafter Vennemann].

17
  Dr. Oleske testified that, in the relevant medical literature, there is no significant difference
between a “mild infection” and an “inflammatory process.” Tr. 50. Similarly, the immune
system “doesn’t differentiate well between artificial infection immunization versus natural
infection.” Tr. 72-73.

                                                  11
and not from an alternate risk factor such as sleep position or excessive blankets); Pet. Ex. 2418
at 1.

        More specifically, Dr. Oleske opined that vaccinations produce an “intense local
response” at the site of injection which, by design, becomes systemic. Tr. 22; 70-71 (“the
inflammatory system that may be initiated by a local infection … soon becomes involved with
the central nervous system or other systemic functions,” such as brain function). “[T]he systemic
system is … associated with a rich interaction with the central nervous system,” making “the
brain and the peripheral immune systems … intimately involved.” Tr. 24-25. The vaccine’s
antigens are designed to “stimulate what’s called T cell responses, which are those responses that
can result in … the long-term protection from anything that happens with infections.” Tr. 24.

        Vaccinations are capable of functioning as “exogenous stressors” when vaccine-induced
cytokine activity reaches the arousal center of an infant’s brain. Tr. 50-51 (Dr. Oleske testifying
that vaccination causes the release of cytokines, both locally and systemically, and that
vaccination always results in an inflammatory response, even in the absence of outward clinical
symptoms); Pet. Ex. 36 at 2 (“[i]n this model, there is support for the role of cytokines as
mediators for such failures of respiratory/ arousal functions in a susceptible infant during this
window of vulnerability.”). Especially in conjunction with adjuvants, 19 vaccinations increase the
presence of the pro-inflammatory cytokines IL-1, IL-2, and IL-6 in the caudal serotonergic area
of the infant’s brain, which inhibits the effect of the 5-HT neurons, whose function is to mediate
the arousal response. Pet. Ex. 36 at 3-4; Tr. 71-72 (describing the role of the 5-HT system in
“control[ling] extreme variations in temperature and respirations and vital signs and vital
status”), 77 (describing the 5-HT system as playing an important role in homeostasis); Tr. 125
(opining that the immunizations “impaired” and “overwhelmed” L.H.’s 5-HT system). See also
Brambilla (explaining that IL-1, an inflammatory mediator, inhibits the firing of 5-HT neurons);
Tr. 85-86.

        Dr. Oleske pointed to epidemiological evidence in support of his testimony regarding the
impact of cytokine activity on the 5-HT system. At least one study has found relatively high
levels of the cytokine IL-1B in the brains of SIDS victims. Kadhim 1 at 1 (finding high levels of
IL-1B in the arcuate nuclei of 17 out of 17 studied SIDS victims, but in only one of six non-SIDS

18
 Kadhim, H., et al., Distinct cytokine profile in SIDS brain: A common denominator in a
multifactorial syndrome?, Neurology, 2003; 61: 1256-59 [hereinafter Kadhim 1].

19
  Dr. Oleske testified that the DTaP and Prevnar vaccines contain “alum-type” adjuvants. Tr.
20. Aluminum adjuvants are “an aluminum-containing compound … that by combining with
soluble antigen forms a precipitate; slow release of the antigen from the precipitate on injection
causes prolonged, strong antibody response.” Dorland’s, 32.

                                                12
brains); Tr. 81-82. Another study has found that IL-6 is elevated in the cerebrospinal fluid
(“CSF”) of SIDS victims. Pet. Ex. 26.20 A third study has shown that IL-6 plays a role in
communication between the peripheral nervous system and the brain. See Pet. Ex. 2921 at 3, 7
(noting that “arousal from quiet sleep is impaired following infection and … this could explain
increased risk for SIDS following infection, as shown in many studies,” and that IL-6 levels were
increased in the CNS of patients who had died of SIDS); Tr. 91-92. According to animal
models, the cytokine IL-B, when injected, can cause apnea and repression of respiration. Pet.
Ex. 2222, 23 23; see also Tr. 79-80. Dr. Oleske argued that several studies have shown a
statistically significant increase in risk for SIDS death following administration of hexavalent
vaccinations. See Pet. Ex. 3124 (finding a 13-fold increase in risk); Pet. Ex. 33 25 (finding
increased risk between zero and seven days post-vaccination).

        In some infants, “there’s a [pre-existing] defect in the 5-HT system, making them more
susceptible to adverse events.” Tr. 72. Normally, when an infant stops breathing, compensatory
mechanisms in the infant’s brain prompt the respiratory system to resume function. Pet. Ex. 36
at 2. When an “‘at risk’ infant stops breathing[,] a disturbance in the usual balance of cytokine
activity in the arcuate nucleus blocks rather than stimulates a normal arousal signal, and the
infant continues not to breath [sic], suffocates and dies (SIDS).” Id., Tr. 192-93; Kinney 2.

        Dr. Oleske argued that the exogenous stressors at play in the Triple Risk Theory need not
be limited to the mechanistic obstacles to respiration, such as upper respiratory infections
(“URIs”), that were specifically identified by Dr. Kinney; in Dr. Oleske’s view, other types of
mild infections may, by virtue of the cytokine activity they prompt, also function as exogenous

stressors. Tr. 34-35. In support of this proposition, Dr. Oleske cited Rognum, according to
which 40 percent of SIDS have been associated with “minor infection cases [with] a history of
‘colds’ or fever around the time of death.” Tr. 36-46; Rognum. According to Rognum,

       Mild infection, especially in combination with prone sleeping condition, may be
       important exogenous triggers. In this regard, mild infection increases risk 1.7-
       fold, prone position 10.4-fold, and the two in combination, 29-fold. Now, by
       initiating a cytokine cascade, mild infection may trigger sudden death in an infant
       with an underlying pathophysiological process in the brainstem.

Rognum at 520 (noting also that there was an increase in IL-6 in the brains of infants who had
died of SIDS); Tr. 87-88. See also Pet. Ex. 27 26 (noting that SIDS victims often have preceding
mild infection/ inflammatory conditions).

         Dr. Oleske has identified evidence in L.J.’s case that her vaccinations 27 were causally
related to her death. He agrees that her death resulted from SIDS. Tr. 62-63. He testified that
L.J. was healthy prior to her vaccinations, but that she was “somewhat irritable and ate less and
was fussy” afterwards, at bedtime on the day of vaccination. Tr. 20; 206 (“I wouldn’t term L.J.’s
reaction ‘extreme.’ I think she was symptomatic, though, and had evidence of a reaction to the
immunization.”). He believes that L.J. was “in the appropriate sleeping position” on the night of
her death, that there is no evidence to suggest that she was overheated or smothered. Tr. 115-16;
165 (noting that the police found L.J. “face-up”); 169 (testifying that, while they are exogenous
factors identified by Dr. Kinney, there was no evidence that either the blanket or the swaddle put
L.J. at risk). Dr. Olekse testified that, in infants, irritability and decreased appetite – both of
which L.J. exhibited post-vaccination – may be evidence of sickness behavior. Tr. 28, 30, 33.
He testified that, although there is no evidence in the record that L.J. had a fever post-
vaccination, Mrs. Jewell did not take her temperature, and it is possible that L.J. had a fever that
was not noticed by her parents. Tr. 21, 28. Indeed, it is difficult to determine whether any infant
has a fever unless her temperature can be taken with a rectal thermometer; one can’t necessarily
tell from touching an infant that a fever is present. Tr. 28-29. Moreover, Dr. Oleske testified,
L.J. may have had an “inapparent infection,” in which case she appeared perfectly normal
despite the fact that an inflammatory process was occurring inside her; “there’s not always a

26
  Kadhim, H., et al., Interleukin-2 as a neuromodulator possibly implicated in the
physiopathology of sudden infant death syndrome, Neuroscience Letters, 2010; 480: 122-26
[hereinafter Kadhim 2].

27
   Dr. Oleske did not identify one or more of the administered vaccines as causal, but he did
testify that the fact that L.J. received six vaccines at once makes their causative role more likely.
Tr. 124 (“I would not have rated the one immunization to be as impacting as the combination.”).

                                                 14
direct correlation between the level of the inflammatory responses and the symptoms that you
exhibit.” Tr. 66-67.

        Dr. Oleske also believes that L.J. had an “underlying susceptibility” to SIDS, though he
did not point to any biological evidence of this susceptibility in her case. Tr. 73-74; 104-106;
114; 150 (acknowledging a lack of neuropathological expertise, and testifying that he accepted
Dr. Miller’s assertion that L.J. had a brainstem abnormality). Even if L.J. did not have an
identifiable brain abnormality, Dr. Oleske’s theory would be that her vaccinations caused
cytokine activity which impacted her brain and caused her death. Tr. 108-09; 163-64
(immaturity in the 5-HT may be to blame for an increased SIDS risk, even in the absence of
structural abnormality). “[I]n a two-month old, what looks like a normal system is in a stage of
development where it can be very overwhelmed … and you don’t have to have [an identified
defect]”. Tr. 181.

       Finally, Dr. Oleske testified that L.J.’s death occurred 10 to 15 hours post-vaccination,
and that this onset period was temporally appropriate in light of the nature of L.J.’s inflammatory
response. Tr. 57-58. L.J.’s immunological response went from local to systemic “within hours.”
Tr. 132-33.

        Dr. Oleske conceded that, other than the petechiae found in L.J.’s lungs, there was no
evidence of inflammation in L.J.’s case. 28 Tr. 135-36. He argued, however, that he would not
have expected to see any such evidence, because the inflammation caused by the vaccinations
would have occurred on a “microscopic,” “cellular” level. Id. Dr. Oleske also conceded that,
when cytokines are found in the brain, they are not necessarily evidence of an inflammatory
response; cytokines are released “every second of every day,” regardless of inflammation. Tr.
137. Moreover, Dr. Oleske conceded that, in some circumstances and in the right amounts, the
release of cytokines may improve, rather than depress, respiratory responses. Tr. 141-42.
Although “brain cytokines are neuroprotective when they are functioning under normal
circumstances,” they can become neurodamaging in the context of a “perfect storm” for SIDS.
Pet. Ex. 36 at 4; Tr. 82 (one role of cytokines is to exert neuromodulatory effects).

       Finally, Dr. Oleske testified that he is not surprised by the studies, identified by
Respondent, which have concluded that there is no connection between administration of a
hexavalent vaccine and an increased risk of sudden infant death. Tr. 161-62; see also Pet. Ex.

28
  Dr. Oleske later testified that petechiae occurs in almost every death; it is a post-mortem, not
pre-mortem, effect. Tr. 173.

                                                15
30 29, 31 30 (examining sample sizes of 420 and 6, respectively, and finding no link between
vaccination and SIDS). According to Dr. Oleske, it would take a much larger study to identify
any statistically significant increase in risk. Tr. 161-62.

               b. Respondent’s Arguments

                       i. Dr. Lucy Rorke-Adams

                              1. Qualifications

       At the time of hearing, Dr. Rorke-Adams had been a specialist in pediatric
neuropathology for 52 years and had been responsible for postmortem evaluation of central
nervous system disease of at least 10,000 infants/children. Resp’t’s Ex. A at 1. She is currently
board certified in anatomical pathology and neuropathology, is a reviewer and editor of various
neurology and pathology journals, and is the namesake for a $2 million endowment for research
on developmental neuropathology. Tr. 501-03.

       At hearing, Dr. Rorke-Adams was admitted as an expert in pediatric neuropathology. Tr.
504.

                              2. Theory

        Dr. Rorke-Adams testified that, in her view, and for two reasons, there was no
relationship between L.J.’s vaccination and her death: first, because “[t]here’s no evidence that
the vaccination produced any change … [in L.J.’s] clinical presentation in the hours after the
vaccination;” and second, because there was no “evidence in the postmortem examination of any
change to the nervous system that might be attributed to some kind of effect from the
vaccinations.” Tr. 504-05.

        Dr. Rorke-Adams disagreed with Dr. Miller’s assessment of the pathological evidence
and argued, in light of the limited nature of the samples, that the medulla slides “were not
suspicious for” any defect of the arcuate nucleus or 5-HT system. Tr. 509-10. She explained
that, having “looked at about 10,000 brains of infants and about 15,000 in adults over the span of
[her] career, it is not uncommon to have a random selection of medulla in which you do not find

                                               16
… neurons comprising the arcuate nucleus on either side.” Id. Dr. Rorke-Adams also disagreed
with Dr. Oleske’s argument that the petechiae found in L.J. was evidence of inflammation;
petechial hemorrhages are “a very characteristic feature of babies who die suddenly,” regardless
of the cause of death. Tr. 507-08. Dr. Rorke-Adams did agree that L.J. had been “bundled” in a
way that may have implicated one of Dr. Kinney’s risk factors, and that L.J.’s lividity may have
suggested that she was on her side when she died. Tr. 516-17.

        Finally, Dr. Rorke-Adams was reserved about the extent to which Dr. Kinney’s Triple-
Hit theory should be relied upon to explain what happened in L.J.’s case. She questioned Dr.
Kinney’s decision not to test for metabolic abnormalities in the studied SIDS population, noting
that several studies have identified such abnormalities as an alternative cause of death in about
10% of infant deaths previously attributed to SIDS. Tr. 506-07. Dr. Rorke-Adams also
questioned Dr. Kinney’s inclusion of co-sleeping infants in the studied SIDS population because,
she argued, SIDS is a diagnosis of exclusion, and because she believes that “co-sleeping” (also
known as rollovers, layovers, and smothering) should be considered its own, independent cause
of death. Tr. 513-17. Ultimately, Dr. Rorke-Adams believes that the Triple-Hit theory is a
“hypothesis that needs to be proven;” and she does not personally believe that hypoplasia of the
arcuate nucleus is a risk factor for SIDS. Tr. 524, 527.

                      ii. Dr. Christine C. McCusker

                             1. Qualifications

        Dr. Christine McCusker graduated from McMaster University in Hamilton, Ontario, with
a Master of Science (MSc) from the Department of Medical Sciences. Resp’t’s Ex. D. She
subsequently received her MD from McMaster University Medical School and did her residency
training in pediatrics at Montreal Children’s Hospital, McGill University. Id. She completed
clinical fellowship in allergy and immunology at McGill University in Montreal, Quebec. Id. At
the time of hearing, Dr. McCusker was an associate professor of pediatrics at McGill University
in Montreal. Tr. 212.

        At hearing, the undersigned admitted her as an expert in pediatric immunology and
clinical allergy and immunology. Tr. 215.

                             2. Theory

        Dr. McCusker agreed with Petitioners’ experts that infants of a certain age are
particularly susceptible to SIDS because of the “maturation of the sleep arousal center in the
CNS,” and that deficits of medullary 5-HT system “have been implicated in abnormalities in
respiration, arousal and chemoreception.” Tr. 222, 344-46. However, Dr. McCusker disagreed

                                               17
with Petitioners’ experts regarding the likelihood that the vaccinations played a causal role in
L.J.’s SIDS death via a systemic immune response. Although she acknowledged that cytokines
may play a role in the brain’s arousal activities, she disagrees that “cytokine activation secondary
to vaccination [may play a role] in this process.” Resp. Ex. F at 3. One reason for her opinion is
that the cytokine activity triggered by vaccines is likely to be relatively controlled. “[C]ytokines
by their very nature generally act over very short distances. They do not have very long half-
lives, so they are rapidly degraded by the system;” “the vast majority of our inflammatory
immune responses are sufficient at the local site to contain – control the infection, that you never
actually know or see the immune response going on anywhere else.” Tr. 221, 224. Adjuvants,
which were present in the vaccines administered to L.J. for the purpose of augmenting her
inflammatory response, have the effect of, “maintain[ing] the immune response relatively
localized so that there are less systemic events.” Tr. 278-79. Although vaccines do not always
produce localized cytokine activity, it is often local, and it is almost always “well-controlled.”
Tr. 222, 308-09, 344-46. Infants’ immune responses to vaccination, in particular, are likely to be
local: “the infant immune system relies a lot more on … local responses, so that the receptors,
the responsive elements for danger signals are differently regulated … so that the trigger or
default pathway is to respond and contain in an infant.” Tr. 227, 222, 344-46 (testifying that an
infant’s immune response to infection is “qualitatively and quantitatively” different from the
infant’s response to vaccination).

        Dr. McCusker also testified that it is problematic, under Petitioners’ theory of causation,
that L.J. was afebrile after vaccination. Subjects with systemic cytokine activity are usually
febrile. Tr. 221. When cytokines produce a systemic response, it is because they are
communicating with each other to amplify the immune system’s response, via a cascade effect;
when sickness behavior occurs, it is because cytokines are upregulated, either peripherally or in
the CNS. Tr. 221, 327-29. Fever is produced by the cytokines IL-6, TNF-alpha, and IL-1B via
“signal transduction, through the combination of passage of the signal up the line … to the
hypothalamus in the brain, … [where] they affect temperature regulation … in the interior
pituitary.” Tr. 221-22, 247-48. Vaccine-induced systemic cytokine activity capable of affecting
the 5-HT system would also be likely to trigger the brain’s fever response. Tr. 255 (“if you’re
talking about the mechanism by which it’s the peripheral immune response that’s activating the
cytokine response in the CNS, you would expect the pathway to lead to fever”); see also Tr. 469-
70 (Dr. Miller testifying that vaccination prompts systemic upregulation of IL-1, IL-6, and IL-2,
which may prevent an already-defective 5-HT system from stimulating respiration), Pet. Ex. 36
at 3-4 (Dr. Oleske opining that, especially in conjunction with adjuvants, vaccinations increase
the presence of the pro-inflammatory cytokines IL-1, IL-2, and IL-6 in the caudal serotonergic
area of the infant’s brain). Moreover, the cytokine activity that produces fever is designed to
increase, not decrease, arousal. Tr. 255, 281; but see Zinka, Traversa (concluding, on the basis
of animal models, that the cytokine IL-B, when injected, can cause apnea and repression of
respiration).

                                                18
        Dr. McCusker specifically disagrees that vaccination-induced cytokine activity could
serve as an “exogenous stressor” in Dr. Kinney’s model. Tr. 241-42; 300 (describing Dr.
Kinney’s model as “a reasonable hypothesis”). She argues that vaccinations were not
contemplated by Dr. Kinney as a potential exogenous stressor and would be an improper and
unwarranted extension of Dr. Kinney’s theory. Tr. 241-42; Kinney 1 (identifying the exogenous
stressors as sleep position, excessive bundling, soft bedding, and mild URIs). Unlike Dr.
Kinney’s exogenous stressors, which are all mechanical in that they mechanically obstruct
respiration, vaccinations’ alleged affect on respiration is neurochemical. Tr. 270-75. Adding a
neurochemical stressor to a list of mechanical stressors would be like comparing apples to
oranges. Tr. 275.

        Generally speaking, Dr. McCusker testified, no conclusions regarding the causative role
of vaccine-induced inflammation can be drawn on the basis of the presence of cytokines in the
brain or CNS, because these cytokines are often present for reasons unrelated to inflammation.
Tr. 302-05 (testifying that the presence of cytokines plays no causative or etiologic role in
SIDS). Dr. McCusker explained that certain cytokines, such as IL-6, may be found in the brains
of SIDS victims because “stress itself might signal to increase the IL-6 as a compensatory
mechanism.” Tr. 237-38. Another explanation for the increased presence of cytokines in the
brains of SIDS victims is that they are the result of the body’s attempt to compensate for
malformed or immature 5-HT systems; the brain releases such cytokines when it wants to signal
to the respiratory center that it needs to breathe. Tr. 242-44. In cases in which infants die of
SIDS, the 5-HT system has ultimately failed to respond to this compensation attempt, but the
cytokine increase is apparent in autopsy specimens. Tr. 244.

        Even if cytokines were capable of suppressing the respiratory response in a normal brain,
they would be incapable of doing so in a brain with a defective 5-HT system. The presence of
inflammation or vaccination-induced IL-1 in a 5-HT system with a “developmental abnormality”
would not be capable of inhibiting the firing of 5-HT neurons and thereby increasing respiration,
as it would normally do, because the damaged 5-HT system is not capable of responding. Tr.
337-40 (analogizing the interaction to a defective door: “if the cytokine is knocking at the door
… and the lock doesn’t fit, the door doesn’t work, the door won’t open because the 5-HT is
damaged”); see also Resp. Ex. E7 31 (explaining how IL-1B impacts the arousal center of the
brain and may increase, rather than decrease, arousal).

      Indeed, Dr. McCusker testified, “the global literature suggests that there is no association
between vaccination and sudden infant death in large population trials.” Tr. 259-64; see also

Vennemann (finding, in a large case control study from Germany that was conducted as a follow
up to the Zinka study, that here was no association between vaccination and SIDS 32). She
disagreed with Dr. Miller’s assertion that epidemiological studies “not grounded in a through
neuropathological examination” would be likely to identify a causal relationship in SIDS victims
with pre-existing brainstem abnormality. Tr. 261-62 (testifying that “[w]ell-designed
epidemiology is looking for the rare event as opposed to the common event”). Addressing the
Kinney 2 article, the conclusion of which was that medullary 5-HT defects are found in
approximately 70% of SIDS deaths, she argued that “the references don’t all have controls” and
that there was an insufficient sample size. Tr. 341-42.

        Dr. McCusker testified that there was no evidence in L.J.’s case that her immune system
was compromised. Tr. 228. Although she conceded that L.J. may have experienced a mild
infection or a mild immune response without fever, she argued that the absence of fever in L.J.’s
case indicates that “there wasn’t a huge immune response going on;” that “what was happening
was not massive and overwhelming and particularly overwhelming from a CNS point of view.”
Tr. 252, 316. Dr. McCusker testified that L.J.’s symptoms of irritability and lack of appetite
were mild, non-specific, and potentially unrelated to sickness behavior. Tr. 253-54, 316-320.
There was no evidence, in Dr. McCusker’s opinion, of any systemic cytokine activity on the day
of L.J.’s death. Tr. 266.

        Dr. McCusker identified several alternate extrinsic factors that qualify under Dr.
Kinney’s theory as “exogenous stressors” in L.J.’s case, and that may have played a causative
role, independent of any vaccine-induced cytokine activity, in her death. The facts that L.J. was
found by her mother with purple mottling of the right cheek and hand, and that she was on her
right side, suggest that she was side-sleeping on the night she died. Tr. 257. “Side sleeping,” as
well as “prone position,” are risk factors for SIDS. Tr. 258-59; see also Resp. Ex. E-10
(identifying risk factors that include bed sharing, prone or side sleeping, overbundling, soft
bedding, face covered, and recent history of URI; and finding that 99% of SIDS infants had at
least one risk factor for SIDS identified at the time of death). 33 Additionally, when law
enforcement and emergency personnel responded to the scene of her death, L.J. was “bundled”
and “had a blanket on top of her.” Tr. 257-58.

377-87.

   IV.      ANALYSIS

         A. Althen Prong 1

        Under the first prong of Althen, Petitioners are required to set forth a medical theory that
explains how the vaccinations can cause SIDS. Althen, 418 F.3d at 1278. The proffered
“reputable” explanation must be scientifically “sound” and “reliable.” See Moberly, 592 F.3d at
1325; Althen, 418 F.3d at 1278; see also Knudsen, 35 F.3d at 548 (Fed. Cir. 1994) (a causation
theory before a special master must be supported by a “sound and reliable” medical or scientific
explanation). Furthermore, “[a]ssessments as to the reliability of expert testimony often turn on
credibility determinations, particularly in cases . . . where there is little supporting evidence for
the expert’s opinion.” Moberly, 592 F.3d at 1325-26.

        Applying this standard to the instant case, the undersigned acknowledges Dr. Kinney’s
Triple Hit Theory as a hypothetical model for factors relevant to the pathogenesis of SIDS. The
undersigned finds the theory credible, and adopts it as an analytical framework for assessing
Petitioner’s theory of causation. However, the undersigned also finds that there is insufficient
evidence in the record to support Petitioner’s argument that vaccines should be included among
Dr. Kinney’s “exogenous stressors” as a potential causal factor in the pathogenesis of SIDS. The
undersigned agrees with Respondent’s experts that the common thread among Dr. Kinney’s
acknowledged exogenous stressors is that they function as a mechanical obstruction to
respiration, and that it would be an unwarranted extension of Dr. Kinney’s theory to find that a
neurochemical obstacle to respiration, such as vaccination-induced cytokine activity, is of the
same type.

        The undersigned also finds that Petitioners have failed to prove that cytokine activity is
capable of impacting the brain’s 5-HT system in the ways proposed by Petitioner’s experts. The
undersigned acknowledges the existence of animal studies in support of Petitioners’ argument
that injected IL-1B may prolong apnea, but finds that Petitioners have failed to prove that
vaccinations are capable of producing such cytokine activity in the brain. See Froen, Stoltenberg

         B. Althen Prong 2

        Under the second prong of Althen, Petitioners are required to establish “a logical
sequence of cause and effect showing that the vaccination was the reason for the injury.”
Petitioners must also prove that the vaccine actually did cause the alleged injury in the instant
case. See Pafford, 2004 WL 1717359, at *4; Althen, 418 F.3d at 1279.

                                                 21
        As an initial matter, the undersigned finds that Petitioner has failed to prove that L.J.
suffered from any brain defect, either in the form of aplasia or hypoplasia of the arcuate nucleus
or in any other form. Dr. Oleske has conceded that he lacks the neuropathological expertise to
opine regarding the existence of any defect, and Dr. Miller has conceded that his findings
regarding L.J.’s arcuate nucleus are “well short of diagnostic or even more probable than not.”
Tr. 150, 463. Dr. Rorke-Adams testified that the neuropathological evidence in this case was not
suspicious for any defect of the arcuate nucleus or of the 5-HT system. Tr. 509-10.

        Assuming that L.J.’s failure to respond to arousal triggers resulted in part from an
immature, though not defective, 5-HT system, the undersigned also finds that the lack of a
documented fever in L.J.’s case makes it particularly unlikely that systemic cytokine activity was
affecting her brain in the ways suggested by Petitioner’s experts. The undersigned acknowledges
Dr. Oleske’s argument that L.J. may have had an unnoticed fever or an “inapparent infection,”
but is unable to find, in the absence of any affirmative evidence of the existence of an
inflammatory process in L.J.’s case, that systemic cytokine activity was occurring at the time of
her death. See Tr. 28-29 (Dr. Oleske testifying about the difficulties inherent in taking an
infant’s temperature); 66-67 (Dr. Oleske testifying inflammatory responses are not always
associated with symptoms); 221 (Dr. McCusker testifying that subjects with cytokine activity are
usually febrile); 255 (Dr. McCusker testifying that vaccine-induced systemic cytokine activity
capable of affecting the 5-HT system would also be likely to trigger the brain’s fever response);
252, 316 (Dr. McCusker testifying that the absence of fever in L.J.’s case suggests that “there
wasn’t a huge immune response going on” and that “what was happening was not massive and
overwhelming and particularly overwhelming from a CNS point of view”); 469-70 (Dr. Miller
testifying that vaccination may prompt systemic upregulation of IL-6, which is one of the
cytokines associated with fever production). The undersigned also finds that the petechiae found
in L.J.’s lungs was more likely to have been a post-mortem effect than evidence of pre-mortem
inflammation. See Tr. 173 (Dr. Oleske testifying that there is evidence of petechiae in almost
every death), 507-08 (Dr. Rorke-Adams testifying that petechial hemorrhages are “a very
characteristic feature of babies who die suddenly,” regardless of the cause of death).

        Moreover, the undersigned finds that there were exogenous factors at play in L.J.’s case,
factors recognized by Dr. Kinney as potentially causative, that these factors were potential
contributors to L.J.’s death, and that these factors would have functioned independently of the
alleged neurochemical causes. Dr. Miller has conceded that several other of Dr. Kinney’s
identified exogenous stressors may have been at play in L.J.’s case. Tr. 476-77 (agreeing that
L.J. may have been “partially on her right side” at the time of death), 479, 481 (agreeing that she
was potentially subject to hyperthermia and swaddling). The undersigned acknowledges that
multiple stressors create a higher SIDS risk and that such stressors may work “synergistically,”
but finds that Petitioners have failed to prove that this synergistic effect was more likely to have
been caused by neurochemical stressors than it was to have been caused by the Kinney-identified

                                                22
stressors that were objectively observable in L.J.’s case. See Zinka (noting a 13-fold increase in
risk in cases involving multiple risk factors); Tr. 484 (Dr. Miller opining that stressors may work
synergistically).

        C. Althen Prong 3

        If Petitioners’ cytokine theory were viable, the undersigned would find that L.J.’s death
was temporally proximate, under that theory, to the administration of the vaccines. However, in
light of the undersigned’s findings on Althen’s first and second prongs, this proximity does not
advance Petitioners’ claims under Althen.

   V.      CONCLUSION

       The undersigned is sympathetic to the fact that Petitioners lost their child to SIDS.
However, the undersigned finds that Petitioners have failed to prove, by a preponderance of the
evidence, that L.J.’s vaccinations caused her SIDS. Therefore, the undersigned has no choice but
to DENY Petitioners’ claim and DISMISS this petition.

       In the absence of a motion for review filed pursuant to RCFC Appendix B, the clerk of
the court SHALL ENTER JUDGMENT accordingly.

        IT IS SO ORDERED.
