OPINION AND ORDER

DAMICH, Senior Judge:

On July 1, 2013, Petitioner filed a petition for compensation under the National
Childhood Vaccine Injury Act of 1986, 42 U.S.C. §§ 300aa-1 to -34 (2012) (“Vaccine Act”),
claiming that the HPV Gardasil vaccine she received on July 1, 2010 caused her to develop
rheumatoid arthritis (“RA”). On September 15, 2014, Respondent filed its Rule 4(c) Report
asserting that Petitioner was not entitled to compensation because she could not carry the burden
of proof under Althen v. Sec’y of HHS, 418 F.3d 1274, 1278 (Fed. Cir. 2005). After the Rule
4(c) Report was filed, the experts for each party submitted their reports. An entitlement hearing
was held on March 27-28, 2017, and the parties agreed that no post-hearing briefing was needed.
On July 14, 2017, Special Master Brian H. Corcoran denied compensation on the grounds that
Petitioner did not establish by preponderant evidence that the vaccine caused her RA. Olson v.

1
Vaccine Rule 18(b), contained in Appendix B of the Rules of the United States Court of
Federal Claims, affords each party fourteen days in which to object to the disclosure of (1) trade
secrets or commercial or financial information that is privileged or confidential of (2) medical
information that would constitute “a clearly unwarranted invasion of privacy.”

Sec'y of HHS, No. 13-439V, 2017 U.S. Claims LEXIS 1032, at 1 (Fed. Cl. Spec. Mstr. July 14,
2017) (hereinafter “Olson”). There was no motion for reconsideration, and this petition for
review of the Special Master’s decision followed on August 14, 2017.

In her motion for review, Petitioner requests this Court to enter judgment in her favor. In
support, Petitioner argues that the Special Master’s decision was arbitrary, capricious, contrary
or otherwise not in accordance with law in that he: (1) misconstrued her theory, (2) raised her
burden of proof, (3) erred in his conclusions, and (4) improperly weighed the evidence.

For the reasons set forth below, the Court holds that the Petitioner’s arguments are
without merit and that the Special Master’s decision was not arbitrary, capricious, an abuse of
discretion, or otherwise not in accordance with law. Petitioner’s motion for review is, therefore,
DENIED.

I. BACKGROUND

A. Medical History 2

On July 1, 2010, Petitioner received an HPV Gardasil vaccine from her gynecologist,
Angelica Zaid, M.D. At the time of the vaccination Petitioner was 52 years old, and was not
within the medically targeted age group to receive the vaccine. Despite this, Petitioner asked to
receive the vaccine in order to treat warts after learning from her daughter’s dermatologist that it
could be effective.

At the time of the vaccination, Petitioner’s medical history was significant. She was
being treated for hypothyroidism, 3 vitamin D deficiency, osteochondroma, 4 an Achilles tendon
rupture, anemia, lifelong asthma, sinus pressure, facial pain, lung congestion, and chronic
sinusitis.

Petitioner claims that within two weeks after the receipt of the vaccine she began to feel a
burning sensation in both hands. However, the first medical record of these symptoms was made
by Dr. Zaid on December 13, 2010, more than five months after the vaccination. During this
visit, Petitioner reported to Dr. Zaid that she had developed “knuckle enlargement w[ith] pain”
that was persistent after receiving the vaccine. Olson, at 4. For further treatment, Dr. Zaid
referred Petitioner to rheumatologist Alexander Shikhman, M.D.

Petitioner saw Dr. Shikhman for the first time on February 22, 2011, and he noted that

Petitioner’s “clinical presentation [wa]s highly suspicious for reactive arthritis.” 5 Olson, at 5
(emphasis added). Dr. Shikhman then ordered extensive laboratory testing. The results showed
a mildly elevated sedimentation rate, as well as a positive Mycoplasma IgG antibody level –
indicative of a prior resolved infection consistent with reactive arthritis. Petitioner’s test results
for rheumatoid factor and anti-citrullinated peptide antibodies (“ACPA”) were negative.
Rheumatoid factor and ACPA are two antibody markers that are strongly associated with RA.
Olson, at 6.

Petitioner continued to see Dr. Shikhman until late in 2013. During this period, she
continued to experience arthritis-like symptoms, although on occasion she felt better and had
only minor joint pain. Experiencing worsening symptoms, Petitioner began treatment with
Gregory Middleton, M.D., a rheumatologist, on September 10, 2013. Dr. Middleton diagnosed
the Petitioner with “seronegative rheumatoid arthritis.” Olson, at 11. “Seronegative” RA is a
diagnosis of RA despite the absence in the blood of the two antibody markers (mentioned above)
that are strongly associated with RA. Dr. Middleton also attributed the RA to her “immune
system over-reaction from her 2010 HPV vaccine.” Id. To date, Dr. Middleton continues to
treat Petitioner for “mild but deforming seronegative inflammatory arthritis compatible with
rheumatoid arthritis.” Olson, at 12.

B. Petitioner’s Theory

According to Petitioner’s Motion for Review, her medical theory has the following
components:

(1) While people with RA may have pre-existing risk factors or genetic predispositions to
develop the condition, an additional environmental “trigger” or “second hit” is necessary to
precipitate the autoimmune condition.

(2) Vaccines can be an environmental trigger for RA.

(3) Inflammatory lung conditions (as Petitioner had) create a significant risk of RA.

(4) Alum (an adjuvant in the HPV vaccine) 6 can act as an environmental trigger by
activating inflammatory pathways in the lungs of people with inflammatory lung conditions.
Petr.’s Mot. at 4.

5
“Reactive arthritis” is not rheumatoid arthritis. Reactive arthritis is “joint pain and
swelling triggered by an infection in another part of the body. MayoClinic.org, “Reactive
Arthritis,” https://www.mayoclinic.org/diseases-conditions/reactive-arthritis/symptoms-
causes/syc-20354838, (last visited Dec. 7, 2017).

An “adjuvant” is “a substance that aids another, such as an auxiliary remedy.”
Dorland’s Medical Dictionary for Health Consumers, The Free Dictionary, https://medical-
dictionary.thefreedictionary.com/adjuvant, (last visited Dec. 7, 2017). In this case, the adjuvant
boosts the immune system to make more antibodies with the result that the vaccine is more
effective and long-lasting.
3
 Petitioner called two expert witnesses, Dr. Gregory Middleton, a clinical rheumatologist,
and Dr. Lawrence Mayer, a professor of epidemiology. Dr. Middleton prepared three expert
reports and testified at the hearing; Dr. Mayer prepared one expert report and also testified at the
hearing. Petitioner also submitted supportive medical literature.

According to the Special Master’s summation of the expert reports and testimony, Dr.
Middleton elaborated on Petitioner’s medical theory attempting to link RA to the HPV vaccine.
Essentially, Dr. Middleton’s theory was that alum triggered certain protein complexes, called
inflammasomes 7, which are

“key to igniting the autoimmune process relevant to RA’s pathogenesis. . . . Once
such inflammasomes were activated by alum contained in a vaccine, an
inflammatory process . . . central to RA began, because the inflammasomes
themselves mediated the release of other proinflammatory cytokines 8 that fueled
the process. Middleton Rep. at 12-13. [Dr. Middleton] thus posited that because
alum has been demonstrated to stimulate these kinds of inflammasomes known to
be factors in RA, there is a causal relationship between the vaccine and the
pathogenesis of RA.” Id. at 12.

Furthermore, Dr. Middleton linked the inflammasomes that contributed to RA as the same as
those found in patents with inflammatory lung conditions. Id. at 13-14. According to the
Special Master, “many articles Petitioner offered discuss or address the ACPAs 9 that are the
result of citrullination, 10 a process widely understood to be an explanation for RA in numerous
cases (and which allows a link to be drawn between chronic lung infections akin to what Mrs.
Olson experienced and her RA).” Olson, at 63.

C. The Special Master’s Decision

According to Althen v. Sec’y of HHS, 418 F.3d 1274 (Fed. Cir. 2005), to establish a legal
cause in a Non-Table Injury case, Petitioner must establish each of the three Althen prongs by

Anti-citrullinated protein antibodies (“ACPAs”) are biomarkers strongly associated with
RA. Olson, at 12.
10
Citrullination is “the conversion of the amino acid arginine into citrulline (not one of
‘the standard 20 amino acids encoded by DNA in the genetic code’)”. Olson, at 15 citing N.
Sofat et al., Interaction Between Extracellular Matrix Molecules and Microbial Pathogens:
Evidence for the Missing Link in Autoimmunity with Rheumatoid Arthritis as a Disease Model, 5
Frontiers in Microbiology 1-6 (2015) (“Sofat Article”).

preponderant evidence: (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 proximate temporal relationship between vaccination and injury. Althen, 418
F.3d at 1278. This is a non-table injury. 11

The Special Master concluded: (1) that petitioner failed to present reliable, persuasive
evidence of a medical theory causally connecting the HPV vaccination and RA under the facts
and circumstances of this case (prong 1), (2) that petitioner failed to show a logical sequence of
cause and effect between the HPV vaccine and petitioner’s RA (prong 2), and (3) that petitioner
failed to show that the timing between vaccination and the onset of petitioner’s RA was
medically appropriate for the HPV vaccine to be causative (prong 3).

Regarding prong 1, the Special Master noted that it is reliably established that “adjuvants
like alum help stimulate the innate immune system, thereby increasing the efficacy of vaccines.”
Olson, at 59. But the Special Master concluded that it is speculative whether this innate immune
system stimulation “instigated by a single vaccine containing alum would be robust enough, and
occur for long enough, to be pathogenic generally, let alone to cause RA.” Olson, at 60. The
Special Master noted that, although alum is used as an adjuvant in many vaccines, Petitioner
offered no literature that concluded that alum was pathogenic: “If alum can cause RA, there
should be more robust evidence that it is associated with other autoimmune conditions in
different vaccines.” Olson, at 62.

Regarding prong 2, the Special Master found that “her medical history does not provide
the corroboration necessary to conclude that Petitioner’s theory worked out as predicted.”
Olson, at 67.

Regarding prong 3, the Special Master concluded that, although Petitioner’s RA-like
symptoms occurred within one to two weeks of the vaccine, she failed to show that the timing of
the onset of symptoms was “medically appropriate” under the proposed causation theory.
Furthermore, the Special Master added that, since he had rejected Petitioner’s theory in the
context of the prong 1 analysis, “it does not matter that onset of the first obvious symptoms of
Mrs. Olson’s RA was temporally consistent with a theory that itself is not scientifically or
medically reliable.” Olson, at 70 (emphasis in original).

The Special Master came to these conclusions after reviewing the testimony of Petitioner
and of the Petitioner’s experts and their reports and after reviewing supportive medical literature,
including some medical literature that was not filed by Petitioner. Of course, the Special Master
also reviewed the testimony and reports of Respondent’s expert, Dr. Robert Lightfoot, a
rheumatologist.

11
A Table Injury is “an injury falling within the Vaccine Injury Table - corresponding to
one of the vaccinations in question within a statutorily prescribed period of time . . .” Olson, at
44.

 II. STANDARD OF REVIEW

Under the Vaccine Act, the Court may set aside a Special Master’s findings of fact or
conclusions of law only if they are found to be “arbitrary, capricious, an abuse of discretion, or
otherwise not in accordance with law.” 42 U.S.C. § 300aa-12I(2)(B). With respect to findings
of fact, the Special Master has broad discretion to weigh expert evidence and make factual
determinations. See Bradley v. Sec’y of HHS, 991 F.2d 1570, 1575 (Fed. Cir. 1993). The
Federal Circuit has clearly indicated its longstanding standard of review when the Court of
Federal Claims hears petitions on review from the Special Masters:

Congress assigned to a group of specialists, the Special Masters within the Court
of Federal Claims, the unenviable job of sorting through these painful cases and,
based upon their accumulated expertise in the field, judging the merits of the
individual claims. The statute makes clear that, on review, the Court of Federal
Claims is not to second guess the Special Masters [sic] fact intensive conclusions;
the standard of review is uniquely deferential for what is essentially a judicial
process. Our cases make clear that, on our review . . . we remain equally deferential.
That level of deference is especially apt in a case in which the medical evidence of
causation is in dispute.

Hodges v. Sec’y of HHS, 9 F.3d 958, 961 (Fed. Cir. 1993) (internal citations omitted); see also
Snyder v. Sec’y of HHS, 2014 U.S. App. LEXIS 1674, at 10-11 (Jan. 28, 2014) (quoting
Hodges).

In Hines v. Sec’y of HHS, it was stated that “[i]f the special master has considered the
relevant evidence of the record, drawn plausible inferences and articulated a rational basis for the
decision, reversible error will be extremely difficult to demonstrate.” 940 F.2d 1518, 1528 (Fed.
Cir. 1991). This Court ought not to second-guess the Special Master’s fact-intensive
conclusions, particularly in cases “in which the medical evidence of causation is in dispute.”
Hodges, 9 F.3d at 961. In such cases, which often involve expert testimony, the Federal Circuit
has “unambiguously explained that special masters are expected to consider the credibility of
expert witnesses in evaluating petitions for compensation under the Vaccine Act.” Porter v.
Sec’y of HHS, 663 F.3d 1242, 1250 (Fed. Cir. 2011). “Such credibility determinations are
‘virtually unreviewable’” on appeal. Id. at 1251. With respect to questions of law, legal rulings
are reviewed de novo under the “not in accordance with law” standard. See, e.g., Moberly, 592
F.3d at 1321; Munn v. Sec’y of HHS, 970 F.2d 863, 870 n.10 (Fed. Cir. 1992).

III. DISCUSSION

When evaluating a motion for review, it is the Court’s task to determine whether the
Special Master properly considered the relevant evidence in the record, came to a factual
conclusion based on plausible inferences, and provided a reasoned explanation in his or her
decision. Hines, 940 F.2d at 1528. It is not the Court’s task to second-guess the Special Master,
especially in cases “in which the medical evidence of causation is in dispute.” Hodges, 9 F.3d at
961. Thus, on review, the Court accords deference to the Special Master’s factual findings and
fact-based conclusions.

6
 Petitioner raises 31 objections with respect to prongs one and two of the three prong
Althen test. Petitioner did not raise any objections to the Special Master’s decision with respect
to prong three. In her motion for review, Petitioner argues that the Special Master (1)
misconstrued her theory, (2) raised her burden of proof, (3) erred in his conclusions, and (4)
improperly weighed the evidence. As discussed in depth below, these arguments are without
merit. 12

A. Althen Prong 1 and Petitioner’s Objections

Under the first prong of the Althen test, the Petitioner must establish by a preponderance
of the evidence “a medical theory causally connecting the vaccination and the injury.” Althen,
418 F.3d at 1278. This means that Petitioner must demonstrate that the vaccine can cause the
injury that she has alleged by providing a “reputable medical theory.” Pafford v. Sec'y of HHS,
451 F.3d 1352, 1355-56 (Fed. Cir. 2006) (citations omitted). Thus, it is not enough to establish a
mere possibility that the vaccine caused the injury.

Petitioner alleges 18 total objections to the Special Master’s decision with respect to
prong 1. These objections can be grouped into three categories: whether the Special Master
misapprehended Petitioner’s theory (Objections 1, 3, 9, 16, and 17), increased Petitioner’s
burden of proof by requiring particular evidence (Objections 2, 6, 8, 10, 11, 12, 14, and 15), and
erred in making his conclusions (Objections 4, 5, 7, 13, and 18).

Respondent argues that the Special Master properly weighed the evidence and declined to
recognize Petitioner’s theory as persuasive thus failing to meet her burden. Resp. at 8.
Respondent maintains that Petitioner only suggested a theory of causation, whereas Althen and
Moberly held that a petitioner must provide a persuasive medical explanation that is specific to
the case and supported by reliable evidence. Moberly, 592 F.3d at 1322. According to
Respondent, Petitioner did not meet this burden.

1. The Special Master Did Not Misapprehend Petitioner’s Theory.

Petitioner claims that the Special Master “misapprehended petitioner’s medical theory”
on five separate occasions with regard to Althen prong 1. Under Federal Circuit precedent, if a
Special Master misapprehends a petitioner’s theory, the Special Master’s decision must be set
aside. Paluck v. Sec’y of HHS, 786 F.3d 1373, 1380 (Fed. Cir. 2015). The Court holds that the
Special Master did not misapprehend the Petitioner’s theory.

a. Objection 1

According to the Motion for Review, “Petitioner introduced evidence that alum triggers
‘inflammasomes,’ which are immune cellular complexes that recognize ‘danger signals,’

12
The Court observes that after examining each of the 31 objections in detail, it is left
with the general impression that Petitioner has cherry-picked sentences from the Special
Master’s opinion without close regard to their context.
7
including alum. Inflammasomes, in turn, activate particular cytokines that are centrally involved
in asthma, bronchiectasis, and RA.” Petr.’s Mot. at 5. Petitioner alleges that the Special Master
“required evidence that cytokine upregulation [was] itself [a] trigger for RA.” Obj. 1. In other
words, the activation of particular cytokines was a trigger for RA. Petitioner notes that, in his
opinion, the Special Master stated that:

Petitioner has failed to demonstrate that cytokine upregulation allegedly resulting
from vaccine administration is itself a trigger for RA. . .

Olson, at 60. Petitioner claims that it is not an element of her theory that cytokine
upregulation is itself a trigger for RA but rather that something in the chemical environment can
trigger inflammasomes. Petitioner’s theory is a “chain reaction,” that is, the alum in the HPV
vaccine triggered inflammasomes which, in turn, activated particular cytokines centrally
involved in RA.

The Court is puzzled that in her Motion for Review, the Petitioner, on the one hand,
states that she did not argue that cytokine activation is a trigger for RA, when, on the other hand,
(on the same page) she states that “[I]nflammasomes, in turn, activate particular cytokines that
are centrally involved in asthma, bronchiectasis, and RA.” Petr.’s Mot. at 5. It seems that the
disagreement is between the Special Master’s use of the word, “trigger,” and her use of the word,
“centrally involved.”

In any event, there is a connection alleged by Petitioner’s theory between RA and
cytokine activation. In order for Petitioner’s medical theory to be “reputable,” it would seem
that the connection between cytokine activation (mediated by inflammasomes) and RA must be
plausibly one of cause and effect. The Special Master used the word “trigger” to represent this
connection. It is not enough, it would seem, for the Petitioner to propose that cytokine activation
is only “centrally involved.” In other words, the Special Master understood the Petitioner’s
chain reaction theory but felt that the link between cytokine activation and RA was not
sufficiently established to causally connect cytokine activation and RA.

Putting aside this cavil, on page 58 of the Special Master’s opinion, the Special Master
summarized Petitioner’s theory clearly:

Petitioner asserts that vaccines can function as the trigger that sets off the
autoimmune process resulting in RA — particularly due to the inclusion of alum
as an adjuvant.

Olson, at 58. He understood that she alleges that alum was the trigger that started the “chain
reaction.” The Special Master noted that Petitioner’s theory

established a general point — that many different environmental factors could
initiate the process that would cause a susceptible individual to develop RA, and
that it is not unreasonable to consider a vaccine . . . as one of those factors. But it
remains a speculative issue as to whether cytokine production instigated by a
single vaccine containing alum would be robust enough, and occur for long

8
 enough, to be pathogenic generally, let alone to cause RA.

Olson, at 60 (emphasis added).

b. Objection 3

Petitioner also claims that the Special Master misconstrued her theory when he required
evidence “that alum directly precipitates RA.” Obj. 3. Similar to Objection 1, Petitioner asserts
that she never claimed that alum precipitated RA. Instead, her theory was based on how the
alum in the HPV vaccine was the environmental trigger.

In reviewing his decision, the Court notes that the Special Master found that Petitioner
lacked “reliable scientific support,” that alum “could precipitate RA.” The Special Master did
not require evidence that alum directly precipitates RA; he found that it could precipitate RA.
The Special Master’s use of the word “could” left open the possibility that alum could have
caused the RA, but remained unconvinced, as he was unable to determine if her RA was caused
by any other environmental factor. As such, he understood Petitioner’s medical theory and did
not require proof that alum directly precipitates RA, but concluded that Petitioner had not
converted the possibility that alum precipitated RA into a reputable medical theory that explains
how it could.

c. Objection 9

Petitioner also argues that the Special Master misunderstood her theory when he found
that Petitioner “failed to prove that alum alone causes RA.” Obj. 9. Petitioner argues that she
never claimed “alum alone” causes RA but may only trigger RA in people with pre-existing lung
conditions.

The Special Master, again, understood Petitioner’s theory and held that the studies
submitted do “not explain why alum in a vaccine would likely initiate or increase,” the
development of RA and there was, “nothing specific enough regarding any of the possible
triggers . . . to define how the triggering process would theoretically work.” Olson, at 62
(emphasis in original). In other words, the Special Master did not conclude that Petitioner failed
to show that “alum alone” caused RA, but rather found that Petitioner’s theory did not establish
how alum caused her to develop RA.

d. Objection 16

Petitioner also maintains that the Special Master misunderstood her theory as “dependent
on citrullination.” Obj. 16. Citrullination is important in explaining the link between RA and
lung inflammation in general, and the link between Petitioner’s lung inflammation and RA is
part of her theory. (See p. 3 of this opinion.) It is discussed in the Sofat article, which was part
of the medical literature submitted by Petitioner. (See footnote 10 above.)

The Special Master considered that the link between lung inflammation and RA was
scientifically established, but he noted that the explanation in the submissions for this link

9
depended on citrullination. Citrullination is the process by which the amino acid arginine (found
naturally in DNA) is converted into citrulline. Olson, at 15 citing Sofat article. As citrulline is
not one of the amino acids found in DNA, the autoantibodies of the immune system may attack
the citrulline, causing inflammation. Sofat Article at 1-2. This inflammation can occur in the
lung and is also characteristic of RA. Id. These autoantibodies are called anti-citrullinated
protein antibodies (ACPAs), and they are a scientifically accepted marker for RA. Olson, at 63.
According to the Sofat article, relied upon by Dr. Middleton, Petitioner’s expert, citrullination
may first occur in the lungs before it occurs in the joints. But an indicator of citrullination is the
existence of ACPAs, and Petitioner has never tested positive for ACPAs. Olson, at 63. (See p. 3
above.) Thus, the Special Master found that the evidence proposed by Petitioner was “ultimately
inapposite to the present context.” Olson, at 62.

Petitioner protests that “because the antibodies responsible for petitioner’s RA . . . is not
known, she is obviously unable to introduce evidence about how that autoantibody functions.”
Petr.’s Mot. at 15. But, unless Petitioner can propose a theory that does not rely upon
citrullination to establish a link between lung inflammation and RA, we are left to imagine how
lung inflammation is linked to RA. Furthermore, we are left to imagine how alum triggered the
chain reaction that produced Petitioner’s RA in the context of the link between lung
inflammation and RA.

In sum, it appears that Petitioner did introduce a theory linking lung inflammation with
RA that was dependent on citrullination. But this theory could not be linked to Petitioner’s RA
because she did not test positive for ACPAs, which are an effect of citrullination. Therefore, the
Petitioner was thrown back to asserting that there are other explanations to explain the link—
although Petitioner did not provide a plausible theory. It is not enough to satisfy Althen prong 1
to say that because the autoantibodies that may have caused Petitioner’s RA were unknown,
Petitioner is relieved from the obligation to provide a plausible scientific explanation for the
element of her theory that involves a link between lung inflammation and RA.

The Special Master understood Petitioner’s theory.

e. Objection 17

Petitioner also proffers that the Special Master misconstrued her theory by stating:

Certainly Petitioner offered nothing reliable or persuasive . . . that suggests that alum
plays any role in abetting the citrullination process.

Olson, at 64; Obj. 17.

In doing so, Petitioner claims that the citrullination process is not part of her theory, but
rather that the alum activates particular pathways that are responsible for lung inflammation and
these pathways have nothing to do with citrullination.

As noted above, citrullination was an explanation that an expert of Petitioner’s used to
explain the link between lung inflammation and RA, that link being an element of Petitioner’s

10
theory. Insofar as citrullination provides this link, the Special Master noted that there was no
reliable or persuasive evidence that alum would abet the citrullination process. Thus, the Special
Master merely alludes to the fact that the Petitioner’s evidence did not prove that alum abets the
citrullination process. This statement is not equivalent to what Petitioner claims, that the
Petitioner’s theory rested upon the determination that alum abets the citrullination process. As
such, he did not misapprehend Petitioner’s theory.

2. The Special Master Did Not Increase Petitioner’s Burden of Proof.

Petitioner’s second group of objections is that the Special Master increased her burden of
proof by requiring proof of specific biologic mechanisms, experimental evidence, other medical
literature, required testimony of an immunologist, and cloaked the legal standard in a
“credibility” determination. Specifically, Petitioner claims that the Special Master required
evidence of a specific biologic mechanism for two components of her theory: linking alum to RA
and demonstrating how environmental factors trigger RA.

Respondent argues that the Special Master recognized that a biological mechanism is not
a required component of the Petitioner’s medical theory, but because Petitioner offered a specific
biological mechanism, the Special Master was then required to consider it. Resp. at 11.
Respondent also argues that the Special Master did not require an immunologist; he simply took
into consideration that Dr. Middleton was not an immunologist in finding Dr. Middleton’s theory
unpersuasive. Resp. at 11. Finally, Respondent reminds the Court that a Special Master is
allowed to make credibility determinations and that such determinations should ordinarily be
upheld on review, but its Response does not directly address Petitioner’s “cloaking” argument.
Resp. at 7.

a. Objections 2, 10, 11, 12, 14, and 15

As the Federal Circuit held in Moberly, the Special Master is endowed with the authority
to weigh the evidence of a biological mechanism presented to him, and “[a]lthough a Vaccine
Act claimant is not required to present proof of causation to the level of scientific certainty, the
special master is entitled to require some indicia of reliability to support the assertion of the
expert witness.” Moberly ex rel. Moberly v. Sec'y of HHS, 592 F.3d 1315, 1324 (Fed. Cir. 2010)
(citing Terran v. Sec'y of HHS, 195 F.3d 1302, 1316 (Fed. Cir. 1999)). Thus, the Special Master
is authorized to weigh the evidence of the Petitioner’s biologic mechanism.

The Special Master did not require proof of a specific biologic mechanism,
epidemiological evidence, or other medical literature. In fact, the Special Master specifically
noted that, “Program petitioners are not required to offer direct proof supporting their theory, or
even any specific type of evidence, but instead may rely on circumstantial evidence.” Olson, at
57. However, as Petitioner offered evidence of a specific biologic mechanism, the Special
Master was then required to consider it and evaluate its persuasiveness.

After reviewing this evidence, the Special Master concluded that it was not persuasive, or
in the case of the submitted medical literature, even applicable. For example, with regard to the
specific biologic mechanism, because Petitioner identified only that component (the alum

11
adjuvant) of the HPV vaccine as potentially having caused RA, the Special Master concluded it
was “critically important that Petitioner marshal reliable scientific or medical evidence
suggesting that alum could precipitate RA.” Olson, at 61. Thus, in addressing this issue, the
Special Master was not requiring the Petitioner to show that alum was the sole trigger of the
theory, but rather was pointing out that Petitioner had not shown it to be a trigger by
preponderant evidence. The Special Master also discussed the kinds of evidence that, if present,
would have assisted Petitioner in proving her theory, but did not require Petitioner to produce
that evidence. See Olson, at 62 (“If alum can cause RA, there should be more robust evidence
that it is associated with other autoimmune conditions in different vaccines.”).

Moreover, after reviewing the medical literature, the Special Master noted that many of
the articles offered relied on very different factual circumstances from those in this case and,
therefore, gave them little weight. For instance, the Besnard article 13 was an animal study that
explicitly excluded alum as part of the study. Ultimately, the Special Master found that these
differences weakened the relevance and applicability of the articles. Thus, the Special Master
properly considered the relevant evidence in the record, came to a factual conclusion based upon
plausible inferences, and provided a reasoned explanation in his decision.

b. Objections 6 and 8 14

Petitioner also alleges that the Special Master required her to provide the testimony of an
immunologist, implying that only immunologists have the expertise to testify about complex
immune processes. However, this argument is without merit. In his decision, the Special Master
wrote:

Dr. Middleton, though qualified to testify about RA generally and its possible
etiology, lacked the specialized immunologic grounding necessary to explain and
defend in a persuasive manner the theory articulated in this case, given that
theory's dependency on complex immune system processes.

Olson, at 64 (emphasis added). Thus, it is clear to the Court that the Special Master did not
require an immunologist, but rather articulated the reasons as to why Dr. Middleton was not
persuasive—he could neither articulate nor could he defend in a persuasive manner his theory
without more specialized knowledge of the immune system. Considering the complex factors
involved, the Special Master properly weighed and considered the relevant evidence and
provided a reasoned explanation in his decision.

A.-G. Besnard et al., NLRP3 Inflammasome is Required in Murine Asthma in the
Absence of Aluminum Adjuvant, 66 Allergy 1047-57 (2011) (“Besnard”); see Olson, at 28.
14
Objection 8 is entitled, “The decision cloaked an erroneous legal standard with a
‘credibility determination.’” Petr’s. Mot. at 10. But in the one-paragraph explanation of this
objection, Petitioner merely asserts: “In this proceeding, the erroneous legal standard was that
only immunologists have the expertise to testify about the complex immune processes involved
in RA.” Petr’s Mot. at 11. She does not explain how this erroneous standard was
“cloaked…with a credibility determination.”
12
 3. The Special Master Did Not Err In Making Factual Conclusions.

The remaining objections under Althen prong one is that the Special Master applied the
wrong evidentiary standard which led to findings contrary to the factual record. However, the
Special Master incorporated Petitioner’s evidence and weighed the persuasiveness of her
experts’ theory and testimony. The Special Master repeatedly noted that, while Petitioner’s
theory has merit, it simply was not persuasive in this case.

The Special Master noted that the Petitioner offered persuasive evidence that, “persistent
lung inflammation is often associated with RA,” and that it is likely citrullination precedes
ACPA production in the lungs. Olson, at 59.

However, the Special Master concluded that this was not enough to satisfy the burden
under Althen prong 1 showing a medically plausible theory linking the vaccine to RA. The
Special Master stated that even though some of the, “components of Petitioner's theory were
facially sound or reliable (and that Respondent's expert on the injury at issue conceded certain
points relevant to the science behind Petitioner's causation theory) [it] does not lead to the
conclusion that the theory as a whole is reliable or persuasive.” Olson, at 42 (emphasis in
original).

As discussed above, the Special Master understood Petitioner’s theory and was not
persuaded by the medical theory of causation. He thus concluded that she failed to prove this by
preponderant evidence. As the decision of the Special Master properly weighed and understood
the evidence, his decision was not arbitrary, capricious, contrary or otherwise not in accordance
with law and this Court will not second guess his fact intensive conclusions.

B. Althen Prong 2 Objections

With respect to prong two of the Althen test, Petitioner alleges 13 total objections to the
Special Master’s decision. These objections can be grouped into four categories: whether the
Special Master again misapprehended Petitioner’s theory (Objection 28), increased Petitioner’s
burden of proof (Objections 19, 21, 22, 23, 25, 31), erred in making different evidentiary and
legal conclusions (Objections 20, 27, 29, 30), and failed to give proper weight to Petitioner’s
expert testimony (Objections 24, 26).

Respondent highlights that in order to satisfy prong two of Althen, Petitioner must
establish by a preponderance of the evidence that “a logical sequence of cause and effect
showing that the vaccination was the reason for the injury,” and that this is usually supported by
Petitioner’s medical records. Althen, 418 F.3d at 1278. Then applying this standard to the facts
of the case the Respondent concludes that, “[m]ost devastating to petitioner’s case is that
repeated testing confirmed that she did not have the requisite antibodies that would be present if
the citrullination process described by Dr. Middleton had actually occurred in her body.” Resp.
at 13. In other words, because the Petitioner lacked the antibodies associated with this process
she failed to establish the “logical sequence of cause and effect.” Althen, 418 F.3d at 1278.

13
 1. The Special Master Did Not Misapprehend Petitioner’s Theory Under Althen
Prong 2.

Petitioner claims that the Special Master “misapprehended the theory of alum as a trigger
of RA.” Petr.’s Mot. at 22. Petitioner argues that “no part of petitioner’s medical theory posits
‘persistent pathogenic cytokine upregulation’ after alum administration. Rather . . . petitioner’s
medical theory is that alum can be an environmental “trigger” for RA in a person with a chronic
inflammatory lung condition.” Petr.’s Mot. at 23 (emphasis in original). In other words,
“Petitioner’s medical theory is that alum can be an environmental trigger for RA by heightening
the inflammation in a person with a pre-existing inflammatory lung condition[;] th[is] does not
require that there be a “persistent” elevation in inflammation “primarily in the first six months to
a year after vaccination.” Petr.’s Mot. at 23.

In support of this argument, the Petitioner relies on the following excerpt from the
Special Master’s decision:

Most significantly, the record does not reflect the existence of an ongoing
inflammatory process that would establish the persistent, pathogenic cytokine
upregulation that Petitioner's theory envisions after administration of an alum-
adjuvanted vaccine.

Olson, at 67. However, after reviewing the evidence provided, the Special Master found that:

[Petitioner’s] medical history does not provide the corroboration necessary to
conclude that Petitioner's theory worked out as predicted — and leaves open the
possibility that other factors were more likely to have precipitated her RA than the
vaccine.

Olson, at 67. Therefore, the Special Master was discussing how and why he was unable to
determine which “factor” caused Petitioner’s RA, namely, because Petitioner’s medical history
did not corroborate with her own theory of causation. The Special Master explained:

[Petitioner was] missing are other pieces of proof that, under Petitioner's
causation theory, should have been reflected in the medical records. In particular,
Petitioner has consistently tested negative for ACPAs — even though
citrullination, and its connection to persistent inflammatory conditions in the lung,
was repeatedly referenced in both Petitioner's literature and Dr. Middleton's
testimony as significant in establishing an individual's susceptibility to RA given
longstanding respiratory problems.

Olson, at 68. Thus, after reviewing the evidence, he did not misconstrue Petitioner’s theory, but
held it to be inconsistent with her causation theory. Therefore, as the Special Master understood
Petitioner’s theory and properly reviewed the relevant evidence, his conclusion was not arbitrary,
capricious, contrary or otherwise not in accordance with law.

14
 2. The Special Master Did Not Increase Petitioner’s Burden of Proof.

Petitioner’s second category of arguments under prong 2 of Althen maintains that the
Special Master impermissibly raised the burden of proof by requiring: (1) “her to negate
possibilities and alternatives that might have occurred,” (2) “evidence of causation relating to
other vaccines,” (3) “evidence of other autoimmune conditions,” (4) epidemiological evidence,
(5) “evidence of pathological markers,” and (6) “test results consistent with the medical theory.”
See Petr.’s Mot at Objs. 19, 21, 22, 23, 25, and 31.

Petitioner argues that the Special Master required her to negate any alternatives and this
raised her burden of proof. However, he wrote that Petitioner’s theory, “leaves open the
possibility that other factors were more likely to have precipitated,” the RA. Olson, at 67
(emphasis added). This statement does not require Petitioner to negate anything, but rather
highlighted weaknesses in the medical theory proffered by her. Thus, the Special Master did not
raise Petitioner’s burden.

With regard to Petitioner’s argument that the Special Master raised her burden of proof
by requiring her to provide “evidence of causation relating to other vaccines,” and “evidence of
other autoimmune conditions,” these arguments lack merit. In his decision, the Special Master
was not persuaded by her theory that alum in the vaccine caused her RA. As the Special Master
explained,

The fact that many vaccines also contain alum but have not been implicated in RA
or other autoimmune conditions as alleged herein also merits some weight. See,
e.g., Johnson v. Sec'y of HHS, No. 10-578V, 2016 U.S. Claims LEXIS 1284, *8-9
(Fed. Cl. Spec. Mstr. Aug. 18, 2016) (noting the unreliability of the theory that if
an adjuvant can cause an autoimmune disease, it could cause any autoimmune
disease). If alum can cause RA, there should be more robust evidence that it is
associated with other autoimmune conditions in different vaccines.

Olson, at 62 (emphasis added). This statement only indicates that if Petitioner’s theory that alum
in Gardasil caused RA could be proven, other evidence would exist indicating that alum in other
vaccines caused for instance RA, or other autoimmune conditions. As such, the Special Master
was not persuaded and this Court will not second guess his decision.

Further, Petitioner’s attempt to equate the lack of “more robust evidence,” to requiring
epidemiological evidence, along with the allegation that the Special Master required evidence of
pathological markers and “test results consistent with the medical theory,” is misleading. As
explained above, the “more robust evidence” was made regarding the persuasiveness of the
theory, and not the type of evidence provided. Therefore, the Special Master did not require
epidemiological evidence.

Also, as discussed above, the Special Master took into consideration all the evidence
provided and ultimately concluded that he could not find what the “most likely cause was, given
the total absence of any of the biomarkers/antibodies most associated with the disorder.” To the
Special Master, this was the most persuasive evidence. Olson, at 69. And because, “Petitioner

15
has never tested positive for those autoantibodies . . . she cannot credibly propose a theory
involving a process that she cannot also establish occurred to her.” Olson, at 63.

The Special Master did not require any of the evidence described above to establish a
logical sequence of cause and effect, but properly considered the relevant evidence in the record,
came to a factual conclusion based on plausible inferences, and provided a reasoned explanation
in the decision.

3. The Special Master Did Not Err In Making Factual Conclusions.

The Petitioner alleges that the Special Master erred in making findings contrary to the
factual record. Particularly, Petitioner alleges that the Special Master erred when he: “based
findings on evidence not in the record,” found that she “did not have an active immune-mediated
disease course,” lacked “tests that supported her theory,” and failed to recognize that Petitioner
established a plausible medical theory. See Petr.’s Objs. 20, 27, 29, and 30. Upon review, these
allegations are without merit.

a. Objection 20

Petitioner claims that the Special Master based findings of fact on evidence not in the
record by taking into account the lack of evidence that alum causes RA. In support, Petitioner
points to this statement by the Special Master, “The fact that many vaccines also contain alum
but have not been implicated in RA or other autoimmune conditions as alleged herein also merits
some weight.” Olson, at 62.

However, this statement recognizes the weakness of Petitioner’s overall theory, that alum
has not been shown to trigger RA in any vaccine, and does not support the conclusion that he
considered evidence not in the record.

b. Objection 27

Petitioner also argues that, in general, the Special Master erred when he failed to find that
Petitioner established a logical sequence of cause and effect between the receipt of the vaccine
and injury. Petitioner maintains that her biologically plausible theory, “combined with a close
temporal proximity of vaccine administration and the onset of RA, is a valid basis for a medical
opinion that there is a logical sequence of cause and effect between vaccine and injury.” Petr’s
Mot. at 22.

However, as discussed supra, the Special Master did not find her medical theory to be
plausible, thus failing the first element. Moreover, Petitioner’s evidence on this prong rests
solely upon the temporal relationship; this is not enough to establish a link. See Grant v. Sec'y of
HHS, 956 F.2d 1144, 1147-48 (Fed. Cir. 1992) (“the petition must affirmatively demonstrate that
the injury or aggravation was caused by the vaccine. Simple similarity to conditions or time
periods listed in the Table is not sufficient evidence of causation.”).

According to the Special Master, Petitioner failed to show by preponderant evidence that

16
affirmatively demonstrated that the injury was caused by the vaccine, the Special Master
concluded that she failed to meet her burden under Althen. This conclusion is not arbitrary,
capricious, contrary or otherwise not in accordance with law.

c. Objections 29 and 30

Petitioner maintains that the Special Master’s finding that Petitioner “didn’t have tests
that supported her theory was a factual inference wholly unsupported by the record,” and was
arbitrary. 15 Petr.’s Mot. at 24. Petitioner derives this argument from the following statement by
the Special Master:

Petitioner has also pointed to no testing results or other laboratory proof
(primarily in the first six months to a year after vaccination) that would establish
that her causation theory was occurring as expected, such as results evidencing
the presence of ongoing inflammation.

Olson, at 67 (bold in original). However, this is not an arbitrary finding by the Special Master.
The Special Master found that:

The record does not reflect the existence of an ongoing inflammatory process that
would establish the persistent, pathogenic cytokine upregulation that Petitioner's
theory envisions after administration of an alum-adjuvanted vaccine. Overall, as
Dr. Lightfoot observed in his report, Mrs. Olson's case of RA was on the mild end
of the spectrum — reflected in its lengthy course, her ability to tolerate the
associated pain while conducting her life, and the lack of evidence demonstrating
a more progressively severe trajectory.

Olson, at 67 (emphasis added).

Thus, as the Special Master makes clear, Petitioner failed to meet her burden based upon
the record as it was in front of him. As such, the Special Master was not arbitrary, capricious,
contrary or otherwise not in accordance with law.

4. The Special Master Properly Weighed the Evidence

The remaining objections relate to the Special Master’s weight to particular testimony.
The first objection relates to the Special Master’s alleged failure to accord weight to Petitioner’s
epidemiologist expert, Dr. Mayer. The second relates to the Special Master’s alleged failure to
not consider the opinion of the treating physician, Dr. Middleton.

As discussed, the Special Master took into consideration the testimony of Petitioner’s

15
Petitioner also argues that the Special Master’s finding that she both had RA and
“failed to demonstrate the existence of an active immune-mediated disease course,” are
inconsistent and an abuse of discretion. Olson, at 68. However, the Special Master did not
accord this “absence of testing” any “excess weight.” Olson, at 68 n.25.

17
epidemiologist expert, Dr. Mayer; he was just not persuaded by him.

As to the testimony of the physician, Dr. Middleton, “a treating physician’s opinion on
vaccine causation is only as strong as the underlying basis for the opinion.” See Perreira v.
Sec’y of HHS, 33 F.3d 1375, 1377 n.6 (Fed. Cir. 1994). As discussed at length above, the
Special Master was not persuaded by Dr. Middleton’s “underlying basis” for his theory of
causation. As such, the Special Master properly weighed Dr. Middleton’s testimony.

IV. CONCLUSION

For the reasons stated above, the Court DENIES Petitioner’s motion for review and
SUSTAINS the decision of the Special Master. The clerk is directed to enter the judgment
accordingly.

IT IS SO ORDERED.
