                                    OPINION AND ORDER

SWEENEY, Chief Judge

        Petitioner Roy Greene seeks compensation under the National Childhood Vaccine Injury
Act of 1986 (“Vaccine Act”), 42 U.S.C. §§ 300aa-1 to -34 (2018), for an alleged vaccine-caused
injury. Before the court is petitioner’s motion for review of the special master’s decision
denying compensation. 2 As discussed below, the court denies petitioner’s motion.




       1
          Vaccine Rule 18(b), included 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 or (2) medical
information that would constitute “a clearly unwarranted invasion of privacy.” Neither party
objected to the public disclosure of any information contained in this opinion.
       2
          After issuing the decision at issue, the special master was appointed to the position of
chief special master. For simplicity, the court uses the title “special master” throughout this
decision.
                                       I. BACKGROUND

        Petitioner filed a petition for compensation under the Vaccine Act on September 29,
2011, alleging that he developed brachial neuritis as a result of a July 22, 2009 tetanus-diphtheria
(“Td”) vaccination. 3 He asserted two theories of recovery: first, that he was entitled to
compensation pursuant to the Vaccine Injury Table, which provides that brachial neuritis that
develops between two and twenty-eight days after receiving a vaccine containing tetanus toxoid
is a compensable injury; and second, that he was entitled to compensation because the Td
vaccine actually caused his brachial neuritis.

        The special master held a fact hearing in March 2015 to determine the onset date of
petitioner’s symptoms. In a July 31, 2015 decision, the special master remarked that petitioner’s
symptoms satisfied the then-operative definition of brachial neuritis in the Vaccine Injury
Table’s “qualifications and aids to interpretation.” Under that definition, brachial neuritis is

       dysfunction limited to the upper extremity nerve plexus (i.e., its trunks, divisions,
       or cords) without involvement of other peripheral (e.g., nerve roots or a single
       peripheral nerve) or central (e.g., spinal cord) nervous system structures. A deep,
       steady, often severe aching pain in the shoulder and upper arm usually heralds
       onset of the condition. The pain is followed in days or weeks by weakness and
       atrophy in upper extremity muscle groups. Sensory loss may accompany the
       motor deficits, but is generally a less notable clinical feature. The neuritis, or
       plexopathy, may be present on the same side as or the opposite side of the
       injection; it is sometimes bilateral, affecting both upper extremities.

42 C.F.R. § 100.3(b)(7)(i) (2014). The special master then found that petitioner’s symptoms
began no earlier than September 1, 2009––forty-one days after the Td vaccination. Because
petitioner’s symptoms arose after the time period prescribed in the Vaccine Injury Table, the
special master dismissed petitioner’s Table claim.

         Over the next two years, in an effort to resolve petitioner’s remaining claim of actual
causation, petitioner filed two expert reports from Thomas W. Wright, M.D., an orthopedist, and
the parties engaged in settlement discussions. In September 2016, the special master learned that
the settlement discussions had not been successful because respondent rejected as inadequate
petitioner’s showing that forty-one days was a medically acceptable time frame for the Td
vaccine to cause brachial neuritis. Thus, the special master directed petitioner to file a
supplemental expert report. In early 2017, petitioner filed an expert report from Marcel
Kinsbourne, M.D., a neurologist.



       3
         The court derives much of the background from its previous ruling in this case, see
generally Greene v. Sec’y of HHS, 

(2018), and the special master’s August 2,
2019 decision after remand, see generally Greene v. Sec’y of HHS, No. 11-631V, 

(Fed. Cl. Spec. Mstr. Aug. 2, 2019). The remaining information is taken from the
docket of the case and the regulation setting forth the Vaccine Injury Table, 42 C.F.R. § 100.3.

                                                -2-
        In March 2017, respondent filed a motion for a ruling on the record, to which petitioner
responded the following month. In a May 26, 2017 decision, the special master found that the
record did not support petitioner’s claim that the Td vaccine caused his brachial neuritis because
petitioner could not establish, more probably than not, that a forty-one-day period between the
vaccination and the first symptoms of the injury was medically acceptable.

         On June 16, 2017, petitioner filed a motion for reconsideration pursuant to Vaccine Rule
10(e), as well as a supplemental expert report from Dr. Kinsbourne and supporting
documentation (including eighteen medical and scientific articles and a letter/report from Vera S.
Byers, M.D., Ph.D., an immunologist). In his motion, petitioner argued that he had provided
sufficient evidence to establish that a forty-one-day onset period was medically acceptable, but
that if the special master continued to deem the existing evidence insufficient, Dr. Kinsbourne’s
supplemental expert report and supporting documentation would establish the medical
acceptability of the onset period.

        The special master granted petitioner’s motion for reconsideration and then, in a
September 26, 2017 “Decision on Reconsideration Denying Entitlement,” concluded that “[t]he
record [did] not support Petitioner’s allegation that his Td vaccine more likely than not caused
his brachial neuritis 41 days following the vaccination.” Greene v. Sec’y of HHS, No. 11-631V,

, at *7 (Fed. Cl. Spec. Mstr. Sept. 26, 2017). He therefore dismissed
petitioner’s actual causation claim.

        Petitioner filed a motion for review of the special master’s decision denying entitlement.
Because the special master applied the incorrect legal standard when evaluating the evidence
offered by petitioner, the court, in a February 27, 2018 Opinion and Order, granted petitioner’s
motion, vacated the special master’s decision, and remanded the case to the special master to
issue a new entitlement decision. On May 17, 2018, the special master issued a remand decision
in which he denied respondent’s motion for a ruling on the record, determined that respondent
should be provided the opportunity to submit an expert report, and indicated that an entitlement
hearing would likely be necessary.

       Respondent filed an expert report from Eric Lancaster, M.D., Ph.D., a neurologist, on
June 14, 2018. On November 13, 2018, petitioner filed an expert report from Lawrence
Steinman, M.D., a neurologist and immunologist, and a response to Dr. Lancaster’s expert report
from Dr. Kinsbourne. On April 9, 2019, respondent filed Dr. Lancaster’s response to Dr.
Steinman’s and Dr. Kinsbourne’s submissions. Then, on April 29, 2019, petitioner filed a
supplemental expert report from Dr. Kinsbourne. Shortly thereafter, on May 9, 2019, the special
master held an entitlement hearing during which he heard testimony from Dr. Kinsbourne, Dr.
Steinman, Dr. Lancaster, and petitioner.

         The special master issued his entitlement decision on August 2, 2019. After summarizing
the case’s factual and procedural history, he provided an extensive description of the credentials,
reports, and testimony of Dr. Kinsbourne, Dr. Steinman, and Dr. Lancaster, along with the
medical and scientific literature relied upon by the experts. He also set forth the legal standards
for his review of the experts’ opinions, for his review of the medical and scientific literature, and



                                                 -3-
for petitioner to establish causation. Then, the special master analyzed petitioner’s case under
the test for causation set forth in Althen v. Secretary of HHS, 

(Fed. Cir. 2005).

        In Althen, the United States Court of Appeals for the Federal Circuit (“Federal Circuit”)
articulated a three-part test, based on prior precedent, explaining what a petitioner must show to
prove causation under the Vaccine Act:

        [Petitioner]’s burden is to show by preponderant evidence that the vaccination
        brought about [the] injury by providing: (1) a medical theory causally connecting
        the vaccination and the injury; (2) a logical sequence of cause and effect showing
        that the vaccination was the reason for the injury; and (3) a showing of a
        proximate temporal relationship between vaccination and injury.

The special master noted that he had previously concluded that petitioner had
established the first prong of the test, and therefore focused his analysis on the second and third
prongs.

        With respect to the third prong, the special master concluded that petitioner did not
establish, by a preponderance of the evidence, that forty-one days was a medically acceptable
length of time between petitioner’s Td vaccination and the onset of petitioner’s brachial neuritis.
Specifically, he concluded that petitioner’s direct proof was insufficient and that petitioner’s
arguments based on circumstantial evidence––evidence concerning risk intervals and evidence
pertaining to the similarities between brachial neuritis and Guillain-Barré syndrome (“GBS”)––
were unpersuasive. 4 He further noted that respondent successfully rebutted the evidence and
arguments presented by petitioner, finding that respondent’s evidence was persuasive and that
the opinions of petitioner’s experts were not as persuasive as Dr. Lancaster’s opinions. The

        4
          “GBS is an acute monophasic peripheral neuropathy that encompasses a spectrum of
four clinicopathological subtypes . . . .” 42 C.F.R. § 100.3(c)(15)(i) (2017).

        The most common subtype in North America and Europe, comprising more than
        90 percent of cases, is acute inflammatory demyelinating polyneuropathy (AIDP),
        which has the pathologic and electrodiagnostic features of focal demyelination of
        motor and sensory peripheral nerves and nerve roots. Another subtype called
        acute motor axonal neuropathy (AMAN) is generally seen in other parts of the
        world and is predominated by axonal damage that primarily affects motor nerves.
        AMAN lacks features of demyelination. Another less common subtype of GBS
        includes acute motor and sensory neuropathy (AMSAN), which is an axonal form
        of GBS that is similar to AMAN, but also affects the sensory nerves and roots.
        AIDP, AMAN, and AMSAN are typically characterized by symmetric motor
        flaccid weakness, sensory abnormalities, and/or autonomic dysfunction caused by
        autoimmune damage to peripheral nerves and nerve roots.

                                                 -4-
latter conclusion was based, in part, on petitioner’s experts’ purported lack of experience in
treating patients with brachial neuritis.

       With respect to the second prong (which the special master was not required to address
having concluded that petitioner had not satisfied the mandatory third prong), the special master
determined that petitioner had not satisfied his burden of establishing that the Td vaccine did
cause his brachial neuritis. This conclusion was based, in part, on his assessment that the record
lacked any evidence that petitioner was experiencing an autoimmune reaction to the vaccine.

        In accordance with his analysis, the special master concluded that petitioner failed to
establish that the Td vaccine caused his brachial neuritis and therefore dismissed petitioner’s
actual causation claim. Petitioner timely filed a motion for review on September 3, 2019, and
respondent filed a response on October 3, 2019. The court heard argument on January 23, 2019,
and is now prepared to rule.

                                        II. DISCUSSION

                                     A. Standard of Review

       The United States Court of Federal Claims has jurisdiction to review the record of the
proceedings before a special master, and upon such review, may:

       (A) uphold the findings of fact and conclusions of law of the special master and
       sustain the special master’s decision,

       (B) set aside any findings of fact or conclusion of law of the special master found
       to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance
       with law and issue its own findings of fact and conclusions of law, or

       (C) remand the petition to the special master for further action in accordance with
       the court’s direction.

42 U.S.C. § 300aa-12(e)(2). The standards set forth in section 12(e)(2)(B) “vary in application
as well as degree of deference. . . . Fact findings are reviewed . . . under the arbitrary and
capricious standard; legal questions under the ‘not in accordance with law’ standard; and
discretionary rulings under the abuse of discretion standard.” Munn v. Sec’y of HHS, 

, 870 n.10 (Fed. Cir. 1992). Specifically, with respect to the special master’s fact findings,
the court does “not reweigh the factual evidence, assess whether the special master correctly
evaluated the evidence, or examine the probative value of the evidence or the credibility of the
witnesses—these are all matters within the purview of the fact finder.” Porter v. Sec’y of HHS,

, 1249 (Fed. Cir. 2011); see also Hodges v. Sec’y of HHS, 

, 961 (Fed.
Cir. 1993) (“[O]n review, the Court of Federal Claims is not to second guess the Special
Master[’]s fact-intensive conclusions; the standard of review is uniquely deferential for what is
essentially a judicial process.”). “Rather, as long as a special master’s finding of fact is ‘based
on evidence in the record that [is] not wholly implausible, [the court is] compelled to uphold that



                                                -5-
finding as not being arbitrary or capricious.’” 

(first alteration in the
original) (quoting Cedillo v. Sec’y of HHS, 

, 1338 (Fed. Cir. 2010)).

        In the instant case, petitioner enumerates, pursuant to Vaccine Rule 24, three objections
to the special master’s August 2, 2019 decision. First, petitioner contends that the special master
required petitioner to establish that a forty-one-day postvaccination onset period for his brachial
neuritis was medically reasonable rather than medically acceptable, improperly increasing
petitioner’s burden of proof. 5 Second, petitioner contends that the special master arbitrarily and
capriciously found facts related to his experts’ qualifications and theories. Third, petitioner
contends that the special master required him to supply preponderant evidence that the Td
vaccine was the most likely cause of his brachial neuritis rather than preponderant evidence of a
logical sequence of cause and effect between the Td vaccine and his brachial neuritis, again
improperly increasing his burden of proof. Petitioner accordingly requests that the court,
pursuant to 42 U.S.C. § 300aa-12(e)(2)(E), set aside the special master’s findings of fact and
conclusions of law, issue its own findings and conclusions, and determine that he is entitled to
compensation.

                                        B. Legal Standard

       All of petitioner’s objections relate to the special master’s determination that petitioner
had not met his burden of proving that the Td vaccine caused his brachial neuritis. As noted
above, to prove causation under the Vaccine Act, a petitioner must

       show by preponderant evidence that the vaccination brought about [his] injury by
       providing (1) a medical theory causally connecting the vaccination and the injury;
       (2) a logical sequence of cause and effect showing that the vaccination was the
       reason for the injury; and (3) a showing of a proximate temporal relationship
       between vaccination and injury.

; see also Boatmon v. Sec’y of HHS, 

, 1355 (Fed. Cir.
2019) (noting that a petitioner must “prove[] all three Althen prongs by a preponderance of the
evidence”). Under the first prong, a petitioner must demonstrate that the vaccine at issue can
cause the injury alleged. Pafford v. Sec’y of HHS, 

, 1355-56 (Fed. Cir. 2006). To
make this showing, “a petitioner must provide a reputable medical or scientific explanation that
pertains specifically to the petitioner’s case, although the explanation need only be ‘legally
probable, not medically or scientifically certain.’” Broekelschen v. Sec’y of HHS, 

, 1345 (Fed. Cir. 2010) (quoting Knudsen v. Sec’y of HHS, 

, 548-49 (Fed. Cir.
1994)). The second prong requires a petitioner to show “that the vaccine was the ‘but for’ cause
of the harm,” 

, or, in other words, “‘that the vaccine actually caused the
alleged symptoms in [the] particular case,’” 

decision of the special master as
recited by the trial court). Establishing the third prong “requires preponderant proof that the
onset of symptoms occurred within a timeframe for which, given the medical understanding of
the disorder’s etiology, it is medically acceptable to infer causation-in-fact.” de Bazan v. Sec’y

       5
          Petitioner does not challenge the special master’s finding that the onset of his brachial
neuritis occurred forty-one days after his Td vaccination. See Mot. 4 n.3.

                                                 -6-
of HHS, 

, 1352 (Fed. Cir. 2008); accord 

(describing the
requirement as “a medically-acceptable temporal relationship between the vaccination and the
onset of the alleged injury”). In short, a petitioner is required “to prove, by a preponderance of
the evidence, that the vaccine was not only a but-for cause of the injury but also a substantial
factor in bringing about the injury.” Shyface v. Sec’y of HHS, 

, 1352 (Fed. Cir.
1999); see also Moberly v. Sec’y of HHS, 

, 1322 n.2 (Fed. Cir. 2010) (“The
burden of showing something by a ‘preponderance of the evidence,’ the most common standard
in the civil law, simply requires the trier of fact to believe that the existence of a fact is more
probable than its nonexistence before [he] may find in favor of the party who has the burden to
persuade the [judge] of the fact’s existence.” (quoting Concrete Pipe & Prods. of Cal., Inc. v.
Constr. Laborers Pension Trust for S. Cal., 

, 622 (1993))).

        Generally, “[t]he determination of causation in fact under the Vaccine Act involves
ascertaining whether a sequence of cause and effect is ‘logical’ and legally probable, not
medically or scientifically certain.” 

. Thus, causation can be
established with circumstantial evidence––in other words, with medical records or medical
opinion. 

(citing 42 U.S.C. § 300aa-13(a)(1)); see also 

(observing that the “‘logical sequence of cause and effect’ must be supported by a
sound and reliable medical or scientific explanation” (citing Daubert v. Merrell Dow Pharms.,
Inc., 

(1993); Jay v. Sec’y of HHS, 

, 984 (Fed. Cir. 1993))). A
petitioner “need not produce medical literature or epidemiological evidence to establish
causation,” but “where such evidence is submitted, the special master can consider it in reaching
an informed judgment as to whether a particular vaccination likely caused a particular injury.”
Andreu v. Sec’y of HHS, 

, 1379 (Fed. Cir. 2009). But see LaLonde v. Sec’y of
HHS, 

, 1341 (Fed. Cir. 2014) (“In Vaccine Act cases, petitioners must proffer
trustworthy testimony from experts who can find support for their theories in medical literature
in order to show causation under the preponderance of the evidence standard. The level of
specificity of such support may vary from circumstance to circumstance.”). Moreover,

       to say that proof in the form of epidemiological studies or well-established
       medical experience is not mandatory does not mean that the special masters in
       Vaccine Act cases are precluded from inquiring into the reliability of testimony
       from expert witnesses. Weighing the persuasiveness of particular evidence often
       requires a finder of fact to assess the reliability of testimony, including expert
       testimony, and . . . the special masters have that responsibility in Vaccine Act
       cases.

.

                                   C. Petitioner’s Objections

        In his motion for review, petitioner challenges both the special master’s findings of fact
(with respect to petitioner’s experts’ qualifications and theories) and conclusions of law (with
respect to the second and third prongs of the Althen test). Because an arbitrary and capricious
finding of fact can affect a legal conclusion, the court begins its analysis by addressing
petitioner’s second enumerated objection to the special master’s decision.

                                                -7-
  1. The Challenged Findings of Fact Were Either Not Arbitrary and Capricious or Not
                Necessary for the Special Master’s Ultimate Conclusions

       In his second objection, petitioner contends that the special master omitted and misstated
information regarding the qualifications and opinions of Dr. Steinman and Dr. Kinsbourne.
Specifically, he asserts that the special master:

       •   did not mention that Dr. Steinman was an immunologist in addition to a
           neurologist;

       •   found that Dr. Steinman and Dr. Kinsbourne “do not possess demonstrated,
           specific experience studying or treating brachial neuritis and its causes,”
           Greene, 

, at *20, even though Dr. Kinsbourne testified that
           he had treated patients with brachial neuritis while he had a clinical practice
           (which ended in the early 1990s), Hr’g Tr. 28, May 9, 2019 (“Tr.”), and Dr.
           Steinman testified that he has seen “[a]t least 100” cases of brachial neuritis
           over the past forty years, 

recently saw a case of brachial neuritis, 

58, 68, and is a neuroimmunologist who has focused his research on the
           causes and treatments of autoimmune diseases, 

       •   failed to comparably criticize Dr. Lancaster, who testified that he had
           diagnosed and treated “10 to 20” patients with brachial neuritis over the last
           ten years, that his research focus was “autoantibodies to the nervous system,”
           and that his research projects pertained to “autoimmune encephalitis, . . .
           [chronic immune demyelinating polyradiculopathy,] and autoimmune
           neuropathies,” 

       •   ignored the experience of Dr. Wright despite valuing clinical experience over
           knowledge derived from research;

       •   distinguished brachial neuritis and GBS for the purpose of determining a
           medically acceptable onset period by, in part, observing that the former
           primarily affects the axons of neurons while the latter primarily affects the
           myelin sheaths of neurons, despite evidence reflecting that a subtype of GBS
           results from axonal damage;

       •   disregarded petitioner’s direct proof that brachial neuritis can occur forty-one
           days after a triggering event in the form of (1) an article—that the special
           master characterized as an outlier but did not reject as incorrect—describing a
           man who developed brachial neuritis three months after an injury (the
           Morishima article), and (2) Dr. Steinman’s testimony that he had seen cases of
           brachial neuritis developing “four, five, six weeks” after the triggering event,
           

                                                 -8-
       •   refused to give three case reports from Japan (the Moriguchi, Morishima, and
           Naito articles) any weight because of his position that case reports are not
           entitled to much weight, which is derived from a decision of another special
           master who discounted case reports for a purpose other than the one for which
           petitioner offered the case reports in this matter; and

       •   found that there was “nothing from the pre- or post-vaccination record
           suggesting that an autoimmune reaction was brewing in a subclinical form,”
           Greene, 

, at *21, even though no evidence was produced by
           the parties indicating that petitioner would have symptoms that suggested such
           a process.

Respondent does not address most of these contentions head on. Instead, he characterizes
petitioner’s contentions as a “dissatisfaction with the Special Master’s weighing of the evidence,
and in particular, his decision to credit Dr. Lancaster’s opinion over his own experts.” Resp. 11.
Specifically, he asserts that the special master was correct to discount the expert reports of Dr.
Wright because they contained unsupported, conclusory statements, 6 and to find Dr. Lancaster’s
opinion, which the doctor derived from clinical experience, more reliable than the opinions of
Dr. Steinman and Dr. Kinsbourne. In a single sentence at the conclusion of his discussion of
petitioner’s second objection to the special master’s decision, respondent states: “Petitioner’s
claim that the Special Master made arbitrary and capricious findings of fact regarding the
qualifications of petitioner’s experts is impossible to reconcile with the Special Master’s
discussion of their qualifications, credibility, and theories.” 

          Respondent is correct that the court is not to reweigh the evidence presented by the
parties. Indeed, the law is well settled that a special master’s fact finding is entitled to deference
so long as the special master’s findings are based on evidence that is “not wholly implausible
. . . .” 

(quoting 

). Thus, for petitioner’s
contentions that are truly just complaints regarding how the special master valued the evidence—
the discounting of Dr. Wright’s expert reports, the failure to give greater weight to the existence
of a subtype of GBS (not brachial neuritis, the injury suffered by petitioner 7) that is characterized


       6
         Respondent makes the same point regarding the letter/report from Dr. Byers even
though petitioner did not address the special master’s treatment of Dr. Byers’s opinion in his
motion.
       7
           In his decision, the special master found that “[d]espite some of their common features,
GBS is simply not sufficiently comparable to brachial neuritis to apply the same onset timeframe
to both.” Greene, 

, at *18. Indeed, it is axiomatic that diseases and injuries
are not fungible and may have different triggers, courses, and treatments, such that it may not be
appropriate to infer that a vaccine that causes one disease or injury can also cause a different, but
related, disease or injury. Accord 

(“[N]ot all neurologic injuries with an autoimmune
component are the same, even if they have some common features. Ample [Vaccine] Program
authority has noted that, while petitioners may reasonably analogize an injury to other
autoimmune conditions, they cannot prevail solely by doing so.”).

                                                 -9-
by axonal damage, and the failure to give greater weight to the three case studies—the court
concludes that the special master’s findings of fact were not arbitrary and capricious.

        However, several of petitioner’s contentions implicate the accuracy of the special
master’s findings of fact rather than just the weight he placed on the evidence. First, the special
master found the opinions of Dr. Steinman and Dr. Kinsbourne less reliable because they “do not
possess demonstrated, specific experience studying or treating brachial neuritis and its causes,
even if they may have intermittently encountered it in their professional lives,” Greene, 

, at *20, but did not similarly criticize the reliability of Dr. Lancaster’s opinion even
though Dr. Lancaster testified to treating only ten to twenty cases of brachial neuritis and did not
profess to studying brachial neuritis and its causes in particular. In other words, although the
experts—Dr. Steinman and Dr. Lancaster especially—have seen a similar number of cases of
brachial neuritis (adjusted for time) and have studied autoimmune diseases in general rather than
brachial neuritis in particular, the special master did not similarly critique the experts on these
factors. His failure to do so was arbitrary and capricious.

      Moreover, the special master arbitrarily and capriciously misstated and downplayed Dr.
Steinman’s credentials and experience. He remarked:

       Dr. Steinman claimed to have encountered brachial neuritis at least one hundred
       times in his career (although he did not specify when he most recently
       encountered it—or whether his encounters came via his role as professor
       overseeing the work of medical residents, as opposed to his own treatment of
       patients). Dr. Steinman has also published extensively in peer-reviewed journals
       on topics including neuroimmunology and GBS. He has demonstrated expertise
       in both a wide variety of central nervous system diseases (multiple sclerosis in
       particular) and immunologic issues, and claimed great familiarity in treating
       brachial neuritis, although he does not appear to have focused on it over other
       central nervous system diseases (such as multiple sclerosis).

(citations omitted). Contrary to the parenthetical in the special master’s first sentence,
Dr. Steinman testified that he “saw a patient with brachial neuritis” while he “was on duty at
Stanford Hospital very recently,” and that he “know[s] from [his] own practice, as recently as
three weeks ago,” that brachial neuritis “has the hallmarks of an autoimmune condition.” Tr. 51;
see also 

(‘[W]hen I see a patient with brachial neuritis, I like to treat them and make
them feel better faster . . . . “). And, although he remarks that Dr. Steinman “has demonstrated
expertise in . . . immunologic issues,” the special master fails to note that Dr. Steinman is
actually an immunologist.

       Nevertheless, even though the special master’s findings regarding the credentials and
experience of Dr. Steinman were arbitrary and capricious, they were unnecessary for his
conclusion that petitioner did not establish that the Td vaccine caused his brachial neuritis.
Indeed, the special master held that respondent had rebutted petitioner’s showing on the third
prong of the Althen test on the merits of the evidence presented, and only noted petitioner’s
experts’ purported lack of “experience studying or treating brachial neuritis and its causes” as a
separate reason for discounting their opinions.

                                                -10-
        Second, the special master concluded that “what direct proof exists on [the amount of
time brachial neuritis will occur after an instigating trigger] does not preponderate in Petitioner’s
favor,” 

, but did not discuss the Morishima article, which described an onset period of
three months, or the testimony of Dr. Steinman, who had seen onset periods of four to six weeks.
The court does not find the special master’s failure to perform a specific analysis of this evidence
to be arbitrary and capricious. There is no requirement that a special master discuss every piece
of evidence when making a factual finding. See, e.g., Maza v. Sec’y of HHS, 

, 38
(2005) (“The Special Master need not discuss every item of evidence in the record so long as her
decision makes clear that she considered the petitioners’ arguments.”); Snyder v. Sec’y of HHS,

, 466 (1996) (“The special master need not discuss every item of evidence in the
record so long as the decision makes clear that the special master fully considered a party’s
position and arguments on point.”), aff’d, 

(Fed. Cir. 1997); see also Hazlehurst v.
Sec’y of HHS, 

, 1352 (Fed. Cir. 2010) (noting that a reviewing court presumes
that the fact finder has considered all of the material in the record, regardless of whether it is
mentioned in his or her decision). More fundamentally, it is clear that the special master
considered the evidence identified by petitioner because he mentioned it elsewhere in his
decision. See Greene, 

, at *6 (remarking that Dr. Kinsbourne recognized that
the three-month onset period in the Morishima article was an outlier), *19 (same), *9 (describing
Dr. Steinman’s testimony).

         Third, the special master observed that there was “nothing from the pre- or post-
vaccination record suggesting that an autoimmune reaction was brewing in a subclinical form,”

but did not indicate how such a reaction would be reflected in the record given that
“subclinical” means “[n]ot manifesting characteristic clinical symptoms,” Subclinical, The
American Heritage College Dictionary (4th ed. 2004). However, even if the court found the
special master’s observation to be arbitrary and capricious, it is but one of three reasons for the
special master’s conclusion that “[t]he record provides no objective evidence whatsoever—
direct, circumstantial, or otherwise—that Petitioner was experiencing an autoimmune-derived
injury attributable to vaccination.” 

the special master:

       Mr. Greene had no symptoms at all before he presented to the ER in early
       September 2009, and then only reported he had been feeling pain for a few days
       before—consistent with the acutely-presenting nature of brachial neuritis. There
       is nothing from the pre- or post-vaccination record suggesting that an autoimmune
       reaction was brewing in a subclinical form. And none of Mr. Greene’s treaters
       implicated the tetanus vaccine as causative of his injuries—nor did they ever
       propose IVIG treatment to remedy it (something that further undercuts the
       concept that brachial neuritis is properly deemed congruent with GBS—or that
       medical science is increasingly viewing immunosuppressive treatments as
       effective for brachial neuritis).

does not challenge the other two bases of the special master’s conclusion,
the fact that one basis is problematic is of no import.




                                                -11-
        In short, the court rejects petitioner’s second objection to the special master’s decision.
Many of petitioner’s contentions relate to the weight assigned to certain evidence by the special
master, which the court does not review, and the remaining contentions regard findings of fact
that are not arbitrary and capricious or are not critical to the special master’s ultimate
conclusions. The court therefore turns to petitioner’s contentions that the special master
improperly increased his burden of proof under the second and third prongs of the Althen test.

  2. The Special Master Did Not Increase Petitioner’s Burden of Proof Under the Third
                               Prong of the Althen Test

         The court begins with petitioner’s Althen prong three objection: that the special master
required him to establish that a forty-one-day onset period was medically reasonable, a
subjective determination, rather than medically acceptable, an objective determination. He
argues that the evidence in the record reflects that brachial neuritis can develop three months
after a triggering event and, therefore, “medically, it must be accepted that [brachial neuritis] can
arise 41 days post-triggering event.” Mot. 22. Respondent counters that petitioner’s objection

       is plainly inaccurate and must be rejected, as it simply ignores the Special
       Master’s accurate two-page recitation of case law describing petitioner’s burden
       of proof, the whole of the Special Master’s analysis, and the Special Master’s
       specific finding that “Petitioner Has Not Established that his Brachial Neuritis
       Began in a Medically-Acceptable Post-Vaccination Timeframe.” 8

Resp. 11 (footnote added).

        As an initial matter, the court does not understand “medically acceptable” and “medically
reasonable” to be legally distinct concepts for the purpose of analyzing the third prong of the
Althen test. A scientist or doctor who finds an onset period to be medically acceptable would not
find the onset period to be medically unreasonable, and a scientist or doctor who finds an onset
period to be medically reasonable would not find the onset period to be medically unacceptable.
Indeed, two of petitioner’s experts expressed their opinions on the postvaccination timing of the
onset of petitioner’s brachial neuritis in terms of medical reasonableness. Dr. Wright concluded
that petitioner’s forty-one-day onset period was “a reasonable onset window,” Pet’r’s Ex. 22 at 2;

       8
          The “specific finding” recited by respondent is actually a heading in the special
master’s decision. The court is disinclined to treat a heading as a finding of fact or conclusion of
law. Accord Target Stores, Div. of Target Corp. v. United States, 

, 1347
(C.I.T. 2007) (“[A] section heading within a court order is not authority of any sort.”); NSK Ltd.
v. United States, 

, 1256 n.1 (C.I.T. 2006) (“[T]he headings demarcating
separate sections within an opinion are dicta and not binding under the doctrine of stare
decisis.”), aff’d, 

(Fed. Cir. 2007); cf. Tutor Perini Corp. v. Banc of Am. Sec.
LLC, 

, 96 (1st Cir. 2016) (“For though a heading in Tutor Perini’s opening brief
suggests the judge erred in dismissing the intentional-misrepresentation claim, its appellate
papers never explain how this is so. And thus Tutor Perini waived any argument it might have
on that claim.”). However, as set forth below, the court’s conclusion would be the same
regardless of whether it considered the heading in its analysis.

                                                -12-
accord Pet’r’s Ex. 29 at 2 (remarking that “41 days . . . is within a reasonable time . . . to
implicate the vaccine”), and Dr. Kinsbourne concluded that “[t]he interval of 41 days falls within
the 42-day timeframe that is generally recognized as being medically reasonable,” Pet’r’s Ex. 38
at 4; accord Pet’r’s Ex. 45 at 3 (“The medical literature cited above is evidence that a 42-day risk
interval for brachial neuritis is medically reasonable.”). 9 Thus, for present purposes, the terms
“medically acceptable” and “medically reasonable” are interchangeable. Consequently, the
special master could not have increased petitioner’s burden of proof by using the term
“medically reasonable.”

        Even if the court determined that “medically acceptable” and “medically reasonable” are
legally distinct concepts, it would find no error in the special master’s analysis of the third prong
of the Althen test. As respondent notes, the special master accurately described petitioner’s
burden to demonstrate a medically acceptable onset period and the special master’s analysis of
the evidence regarding the timing issue reflects a proper understanding of that burden.
Moreover, the special master clearly indicated that his holding was that petitioner had not shown,
by a preponderance of evidence, that a forty-one-day onset period was medically acceptable. See
Greene, 

, at *21 (“Even if I had found that a forty-one-day timeframe for
onset of brachial neuritis was medically acceptable, the record in this case fails to support the
conclusion that the tetanus vaccine is the most likely explanation for Mr. Greene’s injury.”), *22
(“But after considering the expert witnesses and evidence upon which they relied, it is my
reasoned conclusion that Petitioner has failed—despite abundant opportunity—to preponderantly
substantiate his contention that a forty-one-day onset period for his brachial neuritis was
medically acceptable . . . .”).

        Because the court rejects petitioner’s factual and legal objections relating to the third
prong of the Althen test, it does not disturb the special master’s conclusion that petitioner failed
to establish the third prong by a preponderance of the evidence. The failure to prove one prong
of the Althen test is fatal to petitioner’s attempt to prove that the Td vaccine caused his brachial
neuritis. Accordingly, the court need not address petitioner’s contention that the special master
improperly raised his burden of proving the second prong of the Althen test. 10

       9
           Another of petitioner’s experts, Dr. Steinman, concluded that a forty-two-day risk
interval is “acceptable,” “entirely appropriate,” and “standard for the timing on immunization
induced brachial neuritis.” Pet’r’s Ex. 68.
       10
           However, the court makes two observations. First, the special master’s statement that
“the record in this case fails to support the conclusion that the tetanus vaccine is the most likely
explanation for Mr. Greene’s injury,” Greene, 

, at *21, is not necessarily
incompatible with the applicable legal standard of demonstrating that, more likely than not, the
vaccine did cause the injury. See 

n.2 (“The burden of showing
something by a ‘preponderance of the evidence,’ . . . simply requires the trier of fact to believe
that the existence of a fact is more probable than its nonexistence . . . .” (quoting Concrete Pipe
& Prods. of Cal., 

)); 

(remarking that under the
second prong of the Althen test, a petitioner must show “that the vaccine was the ‘but for’ cause
of the harm” or, in other words, “‘that the vaccine actually caused the alleged symptoms in [the]
particular case’” (quoting the decision of the special master as recited by the trial court)).
Furthermore, the special master accurately described petitioner’s burden of proof and remarked
                                                -13-
                                       III. CONCLUSION

        Although the court likely would have reached a different conclusion on the merits of
petitioner’s claim that the Td vaccine caused his brachial neuritis, 11 it is constrained by binding
Federal Circuit precedent dictating that it is not to reweigh the evidence when the special

in his concluding paragraph that petitioner “failed . . . to preponderantly substantiate his
contention . . . that the tetanus vaccine more likely than not ‘did cause’ his subsequent injury.”
Greene, 

, at *22.

        Second, petitioner’s counsel contended during oral argument that the special master’s
discussion and conclusions regarding the second prong of the Althen test were unexpected
because he had previously found the existence of a “logical cause-and-effect relationship
between Mr. Greene’s receipt of the vaccine and development of brachial neuritis” and that the
focus of the special master and the parties leading up to the postremand fact hearing was on
Althen prong three. Reliance on the special master’s prior holding is problematic for two
reasons. First, the special master’s statement was dicta included in a footnote. See Greene v.
Sec’y of HHS, No. 11-631V, slip p. at 12 n.5 (Fed. Cl. Spec. Mstr. May 26, 2017) (“Because I
have found that Petitioner’s claim did not satisfy one of the three Althen prongs, I include no
further discussion of the remaining two prongs. However, I do find that the first, “can cause”
prong was met, given the ample prior decisions associating the Td vaccine with brachial neuritis,
as well as the showing made in this case by Petitioner’s experts. I also note that (with respect to
the second Althen prong) there is a logical cause-and-effect relationship between Mr. Greene’s
receipt of the vaccine and development of brachial neuritis––although that showing is undercut
by Petitioner’s inability to explain the reasonableness of the temporal interval at issue.
Accordingly, this prong is not met.” (emphasis added) (citations omitted)); see also Co-Steel
Raritan, Inc. v. Int’l Trade Comm’n, 

, 1307 (Fed. Cir. 2004) (explaining that dicta
are “statements made by a court that are ‘unnecessary to the decision in the case, and therefore
not precedential (though [they] may be considered persuasive)’” (alteration in original) (quoting
Obiter dictum, Black’s Law Dictionary 1100 (7th ed. 1999))). Second, as petitioner’s counsel
acknowledged, the special master withdrew the May 26, 2017 decision that included the
statement at issue, rendering it void for all purposes. See Vaccine Rule 10(e)(3)(A).
Furthermore, even though respondent’s counsel did not dispute petitioner’s counsel’s
observation that the focus of the postremand proceedings before the special master was Althen
prong three, counsel for both parties represented that there is nothing in the record indicating that
petitioner would not be required to satisfy Althen prong two upon the withdrawal of the May 26,
2017 decision. Consequently, petitioner’s hearing counsel’s failure to focus on all three prongs
of the Althen test cannot be attributed to any fault of the special master.
       11
            The court is unaware of any decision in which a special master awarded compensation
to a petitioner alleging that his or her brachial neuritis was caused by a tetanus-containing
vaccination administered more than twenty-eight days earlier. However, the lack of such a
decision is not dispositive. See 

(holding that special masters are not
bound by the decisions of other special masters and, “[b]y extension, are not required to
distinguish non-binding decisions of other special masters.”).

                                                -14-
master’s fact findings are based on evidence that is not “wholly implausible.” Thus, 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 judgment accordingly.

        In addition, pursuant to Vaccine Rule 18(b), the parties shall review this decision and
submit any proposed redactions, by providing the court with redlined pages showing the
