                       RULING ON REMAND DENYING RESPONDENT’S
                            MOTION FOR RULING ON RECORD1

       On September 29, 2011, Roy Greene filed a petition for compensation in the National
Vaccine Injury Compensation Program (the “Vaccine Program”),2 alleging that he developed
brachial neuritis as a result of his receipt of the tetanus-diphtheria (“Td”) vaccine on July 22, 2009.
Pet. (ECF No. 1). Mr. Greene originally alleged both a Table injury claim and a “non-Table”
causation-in-fact claim (id. at 2), but I dismissed the Table claim after a March 2015 fact hearing,


1
  This Ruling has been designated “to be published,” and will therefore be posted on the United States Court of Federal
Claims website, in accordance with the E-Government Act of 2002, Pub. L. No. 107-347, § 205, 116 Stat. 2899, 2913
(Dec. 17, 2002) (current version at 44 U.S.C. § 3501 (2014)). As provided by 42 U.S.C. § 300aa-12(d)(4)(B), however,
the parties may object to the published Ruling’s inclusion of certain kinds of confidential information. Specifically,
under Vaccine Rule 18(b), each party has fourteen days within which to request redaction “of any information
furnished by that party: (1) that is a trade secret or commercial or financial in substance and is privileged or
confidential; or (2) that includes medical files or similar files, the disclosure of which would constitute a clearly
unwarranted invasion of privacy.” Vaccine Rule 18(b). Otherwise, the whole Ruling in its present form will be
available to the public. Id.
2
 The Vaccine Program comprises Part 2 of the National Childhood Vaccine Injury Act of 1986, Pub. L. No. 99-660,
100 Stat. 3758, codified as amended, 42 U.S.C. §§ 300aa-10 through 34 (2012) [hereinafter “Vaccine Act” or “the
Act”]. Individual section references hereafter will be to § 300aa of the Act.
at which time I determined that Petitioner’s symptoms arose 41 days after the vaccination, and
thus occurred outside the 28-day limit for the Table claim. 42 C.F.R. § 100.3(a)(I)(B)).

        After the parties were unsuccessful in settling the matter, in 2017 Respondent moved for a
ruling on the record dismissing the claim due to Petitioner’s purported inability (under the third
prong of the Federal Circuit’s test for entitlement established in Althen v. Sec’y of Health & Human
Servs., 418 F.3d 1274, 1278 (Fed. Cir. 2005)) to offer preponderant support for his contention that
a 41-day timeframe for onset of brachial neuritis was medically acceptable. See Motion to Dismiss,
dated March 31, 2017 (ECF No. 90) (“Mot.”)

        On May 26, 2017, I issued a decision denying Petitioner’s request for compensation in this
case and dismissing his claim.3 Petitioner then filed a motion for reconsideration of that decision
on June 16, 2017, along with two supplemental expert reports as well as several items of
previously-unfiled medical literature. ECF Nos. 94-97. I withdrew my Decision in order to
evaluate the merits of the reconsideration request. See Order, dated June 19, 2017 (ECF No. 98)
(“Reconsideration Order”). I subsequently denied entitlement a second time (see Greene v. Sec’y
of Health & Human Servs., No. 11-631, 2017 WL 5382856 (Fed. Cl. Spec. Mstr. Sept. 26,
2017)(“Second Dismissal Decision”) – although in doing so I erroneously conflated the standards
applied to evaluating a reconsideration request with the legal standards applied to entitlement
claims generally. Petitioner sought review of the Second Dismissal Decision, and the Court of
Federal Claims granted his motion on February 27, 2018, remanding this matter back to me for a
new disposition of Respondent’s original motion, based on all evidence Petitioner has submitted
to date and applying the proper legal standards. Greene v. Sec’y of Health & Human Servs., No.
11-631, 2018 WL 1514440 (Fed. Cl. Feb. 27, 2018) (“Review Order”).

        For the reasons stated below, I hereby DENY Respondent’s Motion, because Petitioner has
now offered sufficient evidence to support his claim on the timing prong of the Althen test.
However, I do not find that Petitioner is at this time entitled to an award of damages, because the
record remains incomplete - Respondent has requested the opportunity to offer his own expert on
the third Althen prong, and fairness requires me to permit him to do so.

                                                 Factual History

       The facts relevant to the present decision are set forth in my earlier onset fact ruling. See
Greene v. Sec’y of Health & Human Servs., No. 11-631, 2015 WL 9056034, at *1-4 (Fed. Cl. Spec.
Mstr. July 31, 2015 (“Fact Ruling”). They are incorporated by reference herein. That fact ruling
was issued after a 2015 hearing at which several witnesses testified, including the Petitioner.




3
 After I issued the order granting Petitioner’s motion for reconsideration that later resulted in the present remand, my
prior entitlement decision was withdrawn from the docket, and thus can no longer be cited.


                                                           2
      For present purposes, the most important findings reached at the Fact Ruling are as
Follows:

       (a) Petitioner received the Td vaccine on July 22, 2009, in his right arm after an injury at
       his workplace;

       (b) Petitioner saw no other healthcare providers in connection with his injury until
       September 7, 2009 (Labor Day of that year), when he went to a hospital emergency room
       in Houston, Texas, complaining of sharp pain in his right upper arm that had begun a few
       days before (and not any time in the month of July or August); and

       (c) after hearing witness testimony and comparing it to the medical records filed in the
       case, I determined that onset of Petitioner’s subsequently-diagnosed brachial neuritis had
       occurred no earlier than September 1, 2009 (or 41 days post-vaccination).

See generally Fact Ruling at *1-4, *17.

                               Brief Procedural Review Summary

        Between the time of the Fact Ruling and the fall of 2016, the parties had no success in
settling the non-Table claim despite their concerted efforts. In that period, Petitioner submitted
two expert reports from an orthopedist, Thomas W. Wright, M.D. (see Report dated December 18,
2015, ECF No. 62 (Ex. 22) (“First Wright Rep.”); Report dated April 25, 2016, ECF No. 66 (Ex.
29) (“Second Wright Rep.”)). But Respondent took issue with the adequacy of the opinions
expressed therein – arguing in particular that more was needed on the third Althen prong because
of the conclusory nature of Dr. Wright’s opinion, which relied heavily on the fact that a 41-day
onset was only about two weeks longer than what the Table contemplates as a reasonable
timeframe for onset, rendering the additional time period a de minimis difference.

        In response to Respondent’s objections, I proposed that Petitioner obtain an additional
expert report addressing the Althen prong three issue. See Status Conference Order, dated
September 29, 2016 (ECF No. 72). Mr. Greene filed the supplemental report, from Dr. Marcel
Kinsbourne, on January 6, 2017. See ECF No. 82-1 (Ex. 38) (“Kinsbourne Rep.”). Respondent,
however, deemed this report also inadequate and conclusory. In response (and mindful that the
case was now nearly six years old) I proposed that Respondent either consider the matter contested
and file his own expert report, or in the alternative move for a ruling on the record as it stood. See
Status Conference Order, dated January 26, 2017 (ECF No. 86).

        Respondent took the second option and filed a motion to dismiss in March 2017. See
generally Mot. Importantly, Respondent based his request for dismissal at that time solely on
Petitioner’s purported inability to carry his initial burden of proof. Thus, Respondent argued that
the record itself (which included only the two Wright expert reports plus the supplemental
Kinsbourne report, as well as my fact determination on onset) established “legally insufficient


                                                  3
proof” for a favorable entitlement decision and should therefore be dismissed. Mot. at 1. In
particular, Respondent challenged Dr. Wright’s attempt to “piggyback” on the Table timeframes
for appropriate onset. Id. at 5-6. Respondent also maintained that Dr. Kinsbourne’s report set forth
a scientifically unreliable opinion, and was just as conclusory as Dr. Wright’s reports in assuming
that a 41-day onset period was within what is “generally recognized” as medically reasonable for
other autoimmune illnesses, without providing reliable scientific or medical substantiation for that
proposition. Id. at 8-9.

        Petitioner opposed Respondent’s motion. See Opposition, dated April 17, 2017 (ECF No.
92). He argued that he had “done everything necessary” to establish his claim, pointing out that he
had offered two experts, and three reports, in comparison to Respondent’s none, and urging me to
rule in his favor based upon such evidence, which he deemed “unrebutted.” Opp. at 5. As noted
above, I originally granted Respondent’s Motion in late May of 2017, finding that Petitioner’s
expert reports had not offered persuasive or reliable arguments as to the Althen prongs – and in
particular with respect to timing – sufficient to find he had carried his preponderant evidentiary
burden.

         About 20 days later, however, Petitioner filed a timely motion under Vaccine Rule 10(e)
requesting reconsideration of my dismissal decision. See Motion for Reconsideration, dated June
16, 2017 (ECF No. 97) (“Reconsideration Request”). In so doing, Petitioner argued that the expert
reports he had previously filed did in fact meet the legal standards necessary for a decision in his
favor. Reconsideration Request at 2-3. He also noted the existence of other Program decisions
finding 42 days for onset of other autoimmune illnesses (although not brachial neuritis specifically)
to be medically acceptable. Id. at 4. At the same time, however, Petitioner offered new evidence
to support his claim: (a) a supplemental expert report from Dr. Kinsbourne; (b) an expert report
from an immunologist, Dr. Vera Byers; and (c) 19 additional pieces of previously-unfiled medical
literature. See Kinsbourne Supplemental Report, dated June 13, 2017, filed as Ex. 45 (ECF No.
94-1) (“Kinsbourne Supp. Rep.”)); Byers Report, dated June 15, 2017, filed as Ex. 46 (filed as
ECF No. 94-2) (“Byers Rep.”);4 ECF Nos. 94-96 (Exs. 46-66). These materials did a far superior
job in providing substantiation for Petitioner’s Althen prong three arguments than the previously-
filed expert reports.

        In response, I opted to grant Petitioner’s request for reconsideration. See generally
Reconsideration Order. A few days later, I held a status conference with the parties in which I
elaborated on my reasoning for so doing. See Scheduling Order, dated June 28, 2017 (ECF No.
99). In particular, I stated that (although I considered the new expert reports and literature to have
been filed unjustifiably late), I believed fairness required me to give them consideration. Id. at 1.
I also asked Respondent (in the event the newly-filed literature and expert reports did not convince
him to revisit settlement) to file a brief responding to the arguments set forth therein – but,

4
    The Byers report (which was accompanied by five items of literature) was mistakenly filed twice. See Ex. 59.


                                                           4
importantly, not to file an expert report until I had addressed the substantive evidentiary value of
Petitioner’s supplemental filings. Id. at 2. Specifically, I stated that “I would prefer that
Respondent first attempts to oppose the motion without the need for an expert’s opinion (although
Respondent may express in his opposition the desire to offer an expert report later).” Id. (emphasis
added).

        Respondent filed the requested brief on August 23, 2017. See Response (ECF No. 101). In
it, Respondent argued that the legal grounds for reconsideration under Rule 10(e) had not been met
– in particular because of the grossly dilatory nature of the newly-filed evidence. Response at 1-5.
He maintained as well that the additional expert reports and literature did not make persuasive
points, or relied on inapposite comparisons (in arguing that a 41-day timeframe was acceptable) to
other autoimmune illnesses. Id. at 6-11. In addition - in the event that I were inclined to reverse
my earlier entitlement decision, based on the newly-submitted evidence, and consistent with his
previously-expressed desire - Respondent asked that he be provided the chance to obtain and file
an expert report of his own. Id. at 5, 11.

        After reconsidering my original decision, I issued a second decision dismissing Petitioner’s
claim. See generally Second Dismissal Decision. Relying in part on the Rule 10(e) standard for
reconsideration, I deemed the newly-filed materials as too dilatory in character to establish
persuasive grounds for a different outcome, especially given the extent to which they largely were
inapposite to present circumstances. I also found that Petitioner’s existing evidence did not meet
his burden of proof, especially with respect to the third Althen prong, in some part because it was
too circumstantial in character, and thus (under the reconsideration standard)5 not evidence that
should be given much weight so late in the case’s procedural life.

        I did, however, note that some of the newly-filed evidence was more reliable or persuasive
than what Petitioner had previously offered. See, e.g., A. Rowhani-Rahbar, et al., Biologically
Plausible and Evidence–Based Risk Intervals in Immunization Safety Research, 31 Vaccine 271,
271–77 (2012), filed as Ex. 48 (ECF No. 94-4) (“Rowhani-Rahbar”). Rowhani-Rahbar proposes
risk interval estimates for two adverse events following vaccine administration – febrile seizures
and acute disseminated encephalomyelitis (“ADEM”). Id. at 273. For ADEM (an inexact, but not
unreasonable, analog to Petitioner’s brachial neuritis, given its neurologic nature), Rowhani-
Rahbar concluded that the likely time period from vaccination to onset “best substantiated by
available biological and epidemiologic data” was five to 28 days. Id. at 274. A secondary, longer
interval of two to 42 days was also deemed “biologically plausible,” and therefore worthy of
consideration in order to fully assess a potential safety problem, but was more uncertain, since
“there might be reason to suspect that most of the excess risk, if any, is concentrated in a much
shorter period of time.” Id. at 275. This secondary interval has nevertheless been found persuasive

5
  The standard applied to motions for reconsideration permit special masters to take into account the character of
newly-filed evidence – including whether it could have been filed earlier, as well as its probative value. Cedillo v.
Sec’y of Health & Human Servs., 617 F.3d 1328, 1348 (Fed. Cir. 2010) (finding that the special master “did not abuse
his discretion in declining to grant reconsideration in view of evidence that was previously available”).

                                                         5
by other special masters in cases alleging autoimmune injuries (albeit not involving brachial
neuritis). See, e.g., Day v. Sec’y of Health & Human Servs., No. 12-630V, 2015 WL 8028393, at
*22 (Fed. Cl. Nov. 13, 2015) (applying Rowhani-Rahbar secondary risk interval to case alleging
that petitioner’s multiple sclerosis was vaccine-caused).



                               Court’s Adjudication of Motion for Review

         Petitioner filed a timely motion for review of my second Decision dismissing the case.
Motion for Review, dated October 26, 2017 (ECF No. 103). After considering it and Respondent’s
opposition, the Court granted the motion by Order dated February 27, 2018. See generally Review
Order. The Court determined that I erred in misapplying the “interests of justice” standard, which
is relevant only to a Rule 10(e) motion for reconsideration, to the legal merits of Petitioner’s claim
itself and to the evidence offered in its support. Review Order at *7. Once I had decided to permit
reconsideration at all, I could no longer take into account issues like the dilatory nature of
Petitioner’s supplemental expert filings, and thus in doing so I had prejudiced Petitioner. Id. at *8.

        The Court therefore vacated the Second Dismissal Decision, remanding the matter to me
to be re-determined in light of the proper legal standards applicable in entitlement cases. Review
Order at *6 n.5, *8. The Review Order also specifies that (in accordance with Section 12(e)(2) of
the Act and Vaccine Rule 28(b)) I am to “issue [the] new entitlement decision within ninety days
of the date of this decision,” or by May 29, 2018. Id. at *8 (emphasis in original).



                                          Applicable Legal Standards


         A.       Claimant’s Burden in Vaccine Program Cases

        To receive compensation in the Vaccine Program, a petitioner must prove either: (1) that
he suffered a “Table Injury” – i.e., an injury falling within the Vaccine Injury Table –
corresponding to one of the vaccinations in question within a statutorily prescribed period of time
or, in the alternative, (2) that his illnesses were actually caused by a vaccine (a “Non-Table
Injury”). See Sections 13(a)(1)(A), 11(c)(1), and 14(a), as amended by 42 C.F.R. § 100.3; §
11(c)(1)(C)(ii)(I); see also Moberly v. Sec’y of Health & Human Servs., 592 F.3d 1315, 1321 (Fed.
Cir. 2010); Capizzano v. Sec’y of Health & Human Servs., 440 F.3d 1317, 1320 (Fed. Cir. 2006).6
As already noted, Petitioner’s Table claim was dismissed after issuance of the Fact Ruling.


6
 Decisions of special masters (some of which I reference in this ruling) constitute persuasive but not binding authority.
Hanlon v. Sec’y of Health & Human Servs., 40 Fed. Cl. 625, 630 (1998). By contrast, Federal Circuit rulings
concerning legal issues are binding on special masters. Guillory v. Sec’y of Health & Human Servs., 59 Fed. Cl. 121,

                                                           6
         For both Table and Non-Table claims, Vaccine Program petitioners bear a “preponderance
of the evidence” burden of proof. Section 13(1)(a). That is, a petitioner must offer evidence that
leads the “trier of fact to believe that the existence of a fact is more probable than its nonexistence
before [he] may find in favor of the party who has the burden to persuade the judge of the fact’s
existence.” Moberly, 592 F.3d at 1322 n.2; see also Snowbank Enter. v. United States, 6 Cl. Ct.
476, 486 (1984) (mere conjecture or speculation is insufficient under a preponderance standard).
Proof of medical certainty is not required. Bunting v. Sec’y of Health & Human Servs., 931 F.2d
867, 873 (Fed. Cir. 1991). In particular, a petitioner must demonstrate that the vaccine was “not
only [the] but-for cause of the injury but also a substantial factor in bringing about the injury.”
Moberly, 592 F.3d at 1321 (quoting Shyface v. Sec’y of Health & Human Servs., 165 F.3d 1344,
1352-53 (Fed. Cir. 1999)); Pafford v. Sec’y of Health & Human Servs., 451 F.3d 1352, 1355 (Fed.
Cir. 2006). A petitioner may not receive a Vaccine Program award based solely on his assertions;
rather, the petition must be supported by either medical records or by the opinion of a competent
physician. Section 13(a)(1).

        In attempting to establish entitlement to a Vaccine Program award of compensation for a
Non-Table claim (which is the kind of claim asserted in this matter), a petitioner must satisfy all
three of the elements established by the Federal Circuit in Althen: “(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.” Althen, 418 F.3d at 1278.

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

        Petitioners may satisfy the first Althen prong without resort to medical literature,
epidemiological studies, demonstration of a specific mechanism, or a generally accepted medical
theory. Andreu v. Sec’y of Health & Human Servs., 569 F.3d 1367, 1378-79 (Fed. Cir. 2009) (citing
Capizzano, 440 F.3d at 1325-26). Special masters, despite their expertise, are not empowered by
statute to conclusively resolve what are essentially thorny scientific and medical questions, and
thus scientific evidence offered to establish Althen prong one is viewed “not through the lens of
the laboratorian, but instead from the vantage point of the Vaccine Act’s preponderant evidence
standard.” Id. at 1380. Accordingly, special masters must take care not to increase the burden

124 (2003), aff’d, 104 F. App’x 712 (Fed. Cir. 2004); see also Spooner v. Sec’y of Health & Human Servs., No. 13-
159V, 2014 WL 504728, at *7 n.12 (Fed. Cl. Spec. Mstr. Jan. 16, 2014).


                                                       7
placed on petitioners in offering a scientific theory linking vaccine to injury. Contreras v. Sec’y of
Health & Human Servs., 121 Fed. Cl. 230, 245 (2015) (“[p]lausibility . . . in many cases may be
enough to satisfy Althen prong one” (emphasis in original)). But this does not negate or reduce a
petitioner’s ultimate burden to establish his overall entitlement to damages by preponderant
evidence. W.C. v. Sec’y of Health & Human Servs., 704 F.3d 1352, 1356 (Fed. Cir. 2013) (citations
omitted).

        The second Althen prong requires proof of a logical sequence of cause and effect, usually
supported by facts derived from a petitioner’s medical records. Althen, 418 F.3d at 1278; Andreu,
569 F.3d at 1375-77; Capizzano, 440 F.3d at 1326; Grant, 956 F.2d at 1148. In establishing that a
vaccine “did cause” injury, the opinions and views of the injured party’s treating physicians are
entitled to some weight. Andreu, 569 F.3d at 1367; Capizzano, 440 F.3d at 1326 (“medical records
and medical opinion testimony are favored in vaccine cases, as treating physicians are likely to be
in the best position to determine whether a ‘logical sequence of cause and effect show[s] that the
vaccination was the reason for the injury’”) (quoting Althen, 418 F.3d at 1280). Medical records
are generally viewed as particularly trustworthy evidence, since they are created
contemporaneously with the treatment of the patient. Cucuras v. Sec’y of Health & Human Servs.,
993 F.2d 1525, 1528 (Fed. Cir. 1993).

        However, medical records and/or statements of a treating physician’s views do not per se
bind the special master to adopt the conclusions of such an individual, even if they must be
considered and carefully evaluated. Section 13(b)(1) (providing that “[a]ny such diagnosis,
conclusion, judgment, test result, report, or summary shall not be binding on the special master or
court”); Snyder v. Sec’y of Health & Human Servs., 88 Fed. Cl. 706, 746 n.67 (2009) (“there is
nothing . . . that mandates that the testimony of a treating physician is sacrosanct—that it must be
accepted in its entirety and cannot be rebutted”). As with expert testimony offered to establish a
theory of causation, the opinions or diagnoses of treating physicians are only as trustworthy as the
reasonableness of their suppositions or bases. The views of treating physicians should also be
weighed against other, contrary evidence also present in the record – including conflicting opinions

against each other), aff'd, 698 F.3d 1355 (Fed. Cir. 2012); Caves v. Sec’y of Health & Human

       The third Althen prong requires establishing a “proximate temporal relationship” between
the vaccination and the injury alleged. Althen, 418 F.3d at 1281. That term has been equated to the
phrase “medically-acceptable temporal relationship.” Id. A petitioner must offer “preponderant


                                                  8
proof that the onset of symptoms occurred within a timeframe which, given the medical
understanding of the disorder’s etiology, it is medically acceptable to infer causation.” Bazan v.
Sec’y of Health & Human Servs., 539 F.3d 1347, 1352 (Fed. Cir. 2008). The explanation for what
is a medically acceptable timeframe must also coincide with the theory of how the relevant vaccine
can cause an injury (Althen prong one’s requirement). Id. at 1352; Shapiro v. Sec’y of Health &
Human Servs., 101 Fed. Cl. 532, 542 (2011), recons. den’d after remand, 105 Fed. Cl. 353 (2012),

       B.      Analysis of Expert Testimony

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

         The Daubert factors play a slightly different role in Vaccine Program cases than they do
when applied in other federal judicial fora (such as the district courts). Daubert factors are usually
employed by judges (in the performance of their evidentiary gatekeeper roles) to exclude evidence
that is unreliable and/or could confuse a jury. In Vaccine Program cases, by contrast, these factors
are used in the weighing of the reliability of scientific evidence proffered. Davis v. Sec’y of Health
& Human Servs., 94 Fed. Cl. 53, 66-67 (2010) (“uniquely in this Circuit, the Daubert factors have
been employed also as an acceptable evidentiary-gauging tool with respect to persuasiveness of
expert testimony already admitted”). The flexible use of the Daubert factors to evaluate the
persuasiveness and reliability of expert testimony has routinely been upheld. See, e.g., Snyder, 88
Fed. Cl. at 742-45. In this matter (as in numerous other Vaccine Program cases), Daubert has not
been employed at the threshold, to determine what evidence should be admitted, but instead to
determine whether expert testimony offered is reliable and/or persuasive.

       The fact that a claimant offers an expert opinion does not render the opinion that expert
espouses scientifically reliable or persuasive. Nothing requires the acceptance of an expert’s
conclusion “connected to existing data only by the ipse dixit of the expert,” especially if “there is

                                                  9
simply too great an analytical gap between the data and the opinion proffered.” Snyder, 88 Fed.
Cl. at 743 (quoting Gen. Elec. Co. v. Joiner, 522 U.S. 146 (1997)); see also Isaac v. Sec’y of Health
& Human Servs., No. 08-601V, 2012 WL 3609993, at *17 (Fed. Cl. Spec. Mstr. July 30, 2012),
mot. for review den’d, 108 Fed. Cl. 743 (2013), aff’d, 540 Fed. App’x 999 (Fed. Cir. 2013) (citing
Cedillo, 617 F.3d at 1339).

       C.      Standards for Deciding Entitlement on the Record

        The Vaccine Act and Rules permit special masters to decide petitions on the papers where
(in the exercise of their discretion) they conclude that doing so will properly and fairly resolve the
case. Section 12(d)(2)(D); Vaccine Rule 8(d). The decision to rule on the record in lieu of hearing
has been affirmed on appeal. See Hooker v. Sec’y of Health & Human Servs., No. 02-472V, 2016
WL 3456435, at *21 n.19 (Fed. Cl. Spec. Mstr. May 19, 2016) (citing numerous cases where
special masters decided on the papers in lieu of hearing and that decision was upheld). Hearings
are not required in every matter, no matter the preferences of the parties. Hovey v. Sec’y of Health
& Human Servs., 38 Fed. Cl. 397, 402-03 (1997) (special master acted within his discretion in
denying evidentiary hearing); Burns, 3 F.3d at 417; Murphy v. Sec’y of Health & Human Servs.,
No. 90-882V, 1991 WL 71500, at *2 (Ct. Cl. Spec. Mstr. Apr. 19, 1991).

         Deciding if a case requires a hearing can often turn on what the special master expects will
be accomplished by allowing live testimony. Hearings are most helpful where witness credibility
is at issue, or where posing questions to a witness in order to obtain information not contained in,
or not self-evident from, the existing filings is likely to illuminate matters in dispute. See, e.g.,
Hooker, 2016 WL 3456435, at *21 (discussing a special master’s discretion in holding a hearing
and the factors that weighed against holding a hearing in the matter); Murphy, 1991 WL 71500, at
*2 (no justification for a hearing where the claim is fully developed in the written records and the
special master does not need to observe the fact witnesses for the purpose of assessing credibility).
It may also permit a claimant to expand upon points already set forth in paper filings, or respond
to unanticipated questions raised in the matter – but again, only where necessary to reach a
decision.

        In addition, prior decisions have recognized that a special master’s discretion in deciding
whether to conduct an evidentiary hearing “is tempered by Vaccine Rule 3(b),” or the duty to
“afford[] each party a full and fair opportunity to present its case.” Hovey, 38 Fed. Cl. at 400-01
(citing Rule 3(b)). But that rule also includes the obligation to create a record “sufficient to allow
review of the special master’s decision.” Id. Thus, the fact that a claim is legitimately disputed,
such that the special master must exercise his intellectual faculties in order to decide a matter, is
not itself grounds for a trial (for if it were, trials would be required in every disputed case).




                                                 10
                                                  ANALYSIS

        As already noted, my now-vacated resolution(s) of Respondent’s dismissal motion turned
on the adequacy of Mr. Greene’s Althen prong three showing.7 In particular, I determined that the
expert opinion evidence he had submitted from Drs. Wright and Kinsbourne was conclusory and
unreliable in asserting that a 41-day post-vaccination onset was medically acceptable, and that
Petitioner unreasonably relied on the Table’s timeframe to argue that a timeframe 13 days longer
was still acceptable.

         Petitioner’s more recently-filed expert reports and associated literature provide a variety of
additional evidence to support his position with respect to timing. He has now offered reliable
literature, like Rowhani-Rahbar, that supports his contention that a longer onset for autoimmune
conditions is medically acceptable. He has also offered a more fleshed-out report from Dr.
Kinsbourne, and a report from a third expert, Dr. Byers, also having some bearing on the timing
question. For such reasons, it is appropriate, based upon all such evidence, to deny Respondent’s
March 2017 motion for a ruling on the record. There is sufficient evidence in the record that, if
unrebutted, would allow me to conclude that Petitioner has met his preponderant burden of proof.
The circumstances are now considerably different from when Respondent (based solely on the two
conclusory Wright reports plus Dr. Kinsbourne’s initial report) first moved to dismiss the claim.

         This does not mean, however, that the opposite is true – that Petitioner has carried his
burden based solely upon the existing record (which includes the supplemental expert reports and
literature). Instead, I must in fairness permit Respondent the opportunity to rebut Petitioner’s
expert showing before I can fully rule on entitlement in this case.

        My determination herein is the product of both substantive and procedural considerations.
Substantively, I do not find that a 41-day timeframe for onset of brachial neuritis is a settled matter
in the Program, as Petitioner has argued. Indeed – I have found the opposite to be true in other
cases I have decided involving precisely the same injury. For example, in Garner v. Sec’y of Health
& Human Servs., No. 15-063V, 2017 WL 1713184 (Fed. Cl. Spec. Mstr. Mar. 24, 2017), mot. for
review den’d, 2017 WL 3483352 (Fed. Cl. July 31, 2017), I considered a claim that the Hepatitis
A and B vaccines had caused Parsonage-Turner Syndrome (a parallel descriptor for brachial

7
  My two decision(s) to dismiss the case included no in-depth discussion of the remaining two Althen prongs. However,
it did appear to me, and does now as well, that the first, “can cause” prong has been met, given the ample prior
decisions associating vaccines with a tetanus component with brachial neuritis, as well as the showing made in this
case by Petitioner’s experts. See, e.g., Devonshire v. Sec’y of Health & Human Servs., No. 99-031V, 2006 WL
2970418, at *15 (Fed. Cl. Spec. Mstr. Sept. 28, 2006) (stating that it is well known that brachial neuritis can occur
following a tetanus vaccination), aff’d, 76 Fed. Cl. 452 (2007); DeGrandchamp v. Sec’y of Health & Human Servs.,
No. 01-413V, 2003 WL 21439670, at *7 (Fed. Cl. Spec. Mstr. May 15, 2003) (relying on Institute of Medicine
publications to find that in theory, the tetanus toxoid in Td can cause brachial neuritis). The future disposition of
Petitioner’s claim will not likely turn on the first Althen prong.


                                                        11
neuritis). The earliest onset possible in Garner was 45 days after vaccination, based on the first
record documentation of any complaints by petitioner about arm or shoulder pain. Garner, 2017
WL 1713184, at *1. Respondent’s expert, however, persuasively argued that the condition was far
more acute in nature (and in terms of the causative mechanism as well), making in his opinion four
weeks, or 28 days, the outer limit for latency. Id. at *8. I found this point to be dispositive, even
though the claimant’s Althen prong one showing was (as here) sufficient, and dismissed the case
on the record. Id. at 16.

        Nothing Petitioner has argued in this case is any more persuasive facially than what I have
previously rejected. Tellingly, Petitioner has cited no contrary cases involving brachial neuritis
and a timeframe equivalent to that herein, and although I am not bound by the decisions of other
special masters, they can be persuasive and relevant in understanding whether a claimant has met
his burden. Hanlon v. Sec’y of Health & Human Servs., 40 Fed. Cl. 625, 630 (1998). I thus have
doubts about the sufficiency of Petitioner’s current evidentiary showing, and those doubts are best
resolved by permitting Respondent the opportunity to offer his own expert views on the subject.8

        I also note that I have reasonable misgivings about the weight to give the existing expert
support offered on this point based on questions regarding expert credentials and competency. For
example, I must evaluate whether Dr. Kinsbourne’s lack of direct expertise in studying,
researching, and/or treating brachial neuritis (let alone any patients for many years) is grounds for
giving his views less weight. Holmes v. Sec’y of Health & Human Servs., No. 08-185V, 2011 WL
2600612, at *2 n.9 (Fed. Cl. Spec. Mstr. April 26, 2011) (noting that Dr. Kinsbourne has not had
a clinical neurology practice for 37 years), aff’d 115 Fed. Cl. 469 (2014). I also wish for
Petitioner’s experts to explain why literature offered relating to other autoimmune conditions, and
the timeframe in which a vaccine would cause the relevant pathogenic reaction, can be analogized
to brachial neuritis. In addition, should Petitioner call Dr. Wright at hearing, I would expect to
probe the degree to which the opinion he previously offered on the timing issue relied on his own
experience treating individuals with brachial neuritis, as opposed to his conclusory determination
that the Table time periods were not that far off the time period in question (something Program
law says is not permitted). All of the above will likely require a hearing, in order to assess expert
credibility and probe the extent to which their opinions deserve the weight requested. Under such
circumstances, I cannot rule favorably for Petitioner on entitlement without a more complete
opportunity to weigh all the evidence together – which means directing Respondent to file an
expert report.

      Procedurally, I find that the present record remains incomplete on the timing issue.
Respondent has not had the opportunity to offer his own expert to address the points raised in

8
  Of course, if Respondent opted not to file an expert report in this case, but were instead simply to ask me to decide
the case based on the evidence as it stands, I would likely be compelled despite my doubts to find that he had met his
burden, if barely. But Respondent has indicated the desire to file an expert report.


                                                         12
Petitioner’s existing evidentiary showing. This is not something that I am raising sua sponte.
Rather, the potential utility and necessity of a counter-expert was raised by Respondent in opposing
the reconsideration request, in the event his motion to dismiss were denied after reconsideration.
See Response at 5. Respondent wishes to offer an expert report of his own, and fairness dictates
that I allow Respondent that opportunity.9 See Rule 3(b)(2).

         I also find that a hearing will likely be necessary before I can reach an entitlement decision
in this case, given the present record (which in my estimation is incomplete for the reasons stated).
As noted above, it is within a special master’s discretion to decide when a hearing is required –
and that decision can turn on whether the chosen form of adjudication “affords each party a full
and fair opportunity to present its case.” Hovey, 38 Fed. Cl. at 400-01 (citing Rule 3(b)). In some
cases, I have decided that the matters presented could be reasonably resolved without hearing. See,
e.g., D’Toile v. Sec’y of Health & Human Servs., No. 15-85V, 2016 WL 7664475, at *25-28 (Fed.
Cl. Spec. Mstr. Nov. 28, 2016) (resolving claim based on expert submissions and without hearing),
mot. for review den’d, 132 Fed. C. 421 (2017), aff’d, No. 2017-1982, slip op. (Fed. Cir. Apr. 12,
2018). Here, I reach the opposite conclusion – to afford Respondent a “full and fair” opportunity
to articulate his defense, and also to permit Petitioner to examine Respondent’s experts, I will
require an entitlement hearing mainly focused on the third Althen prong, in order to assess expert
credibility and probe the bases for the opinions offered.

        Petitioner’s reconsideration request also suggested that Respondent’s failure to offer an
expert report requires me to find that Petitioner’s evidence is unrebutted, but such arguments fly
in the face of the evidentiary weighing and credibility determinations afforded to the special
masters. As a general matter, I am not required to adopt the opinions of a petitioner’s experts
wholesale - even where Respondent chooses not to offer a rebuttal expert. See Barone v. Sec’y of
Health & Human Servs., No. 11-707, 2014 WL 6834556, at *12 (Fed. Cl. Spec. Mstr. Nov. 12,
2014) (evaluating reasonableness and reliability/persuasiveness of Petitioner’s expert showing,
despite the fact that Respondent had offered no rebuttal expert of his own). Indeed, in discussing
the duties of the special masters, the Court of Federal Claims has previously noted that “[n]o judge
or jury can be forced to accept or reject an expert’s opinion or a party’s theory at face value,” and
that to propose that special masters must do otherwise “is to neglect the Special Master’s duty to
‘vigorously and diligently investigate the factual elements’ underlying [a] petition.” Sword v.
United States, 44 Fed. Cl. 183, 188 (1999), citing Mills v. Sec’y of Health & Human Servs., 27


9
  In opting to seek a ruling on the record, Respondent has not waived the right to offer his own expert. Respondent’s
brief reacting to the Reconsideration acknowledges that Respondent was willing to forego offering an expert at the
time of the first motion to dismiss, filed in March 2017. Response at 5. But once Petitioner offered supplemental
expert reports and additional literature in the context of his reconsideration request, Respondent was explicit in asking
that he too be permitted to obtain an expert opinion. Id. I in fact asked that Respondent forestall that effort, since I was
unsure the degree to which I would find the Petitioner’s new evidence persuasive. Scheduling Order at 2 (ECF No.
99). Now, applying the correct legal standard, I find the newly-filed evidence to be sufficient to defeat Respondent’s
motion – but not enough to result in judgment for Petitioner.

                                                            13
Fed. Cl. 573, 578 (1993). I may thus weigh the evidence offered by a petitioner in determining in
the first instance if he has met his burden of proof.

        In addition, I am empowered to permit, and to request, the filing of additional evidence in
my role as special master – even at the later stages of a proceeding. Parties in Program cases are
allowed many opportunities to supplement a record with expert support, and have been permitted
to do so even immediately before or after a hearing’s completion, or after issuance of an
entitlement decision. See, e.g., Cedillo v. Sec'y of Dep't of Health & Human Servs., No. 98–916V,
2009 WL 331968, *62 (Fed. Cl. Spec. Mstr. Feb. 12, 2009), aff'd, 89 Fed. Cl. 158 (2009), aff’d,
617 F.3d 1328 (Fed. Cir. 2010) (special master permitted two expert reports to be filed only four
days before the hearing in the case was to commence); Vant Erve v. Secretary of Department of
Health & Human Services, 39 Fed. Cl. 607 (1997), aff'd after remand, 232 F.3d 914 (Fed. Cir.
2000) (unpublished table decision) (special master’s refusal to reopen a question of liability was
an abuse of discretion even though three years had passed since decision; information offered by
Respondent was highly probative, there was no showing of prejudice to Petitioners, and
Respondent was not at fault for the delay). Such discretion flows from the special master’s
authority to determine whether, when, and how to take and consider evidence in resolving a
petitioner’s entitlement to damages. Hovey, 38 Fed. Cl at 400 (concluding that it was within the
special master’s discretion to determine whether to allow in new evidence after an evidentiary
hearing in the case); Section 12(d)(3)(B) (special master afforded discretion when making
determinations regarding admission of evidence).

        Here, my misgivings about the adequacy of Petitioner’s current evidentiary showing make
it impossible for me to decide the case on the existing record, and may best be addressed by
permitting a counter-expert’s testimony. Allowing Respondent to file an expert report under the
present circumstances would not otherwise prejudice Petitioner. I have previously in this case
bemoaned the excessive amount of time it is taking to resolve the matter, so it pains me to increase
delay – but Petitioner’s refusal earlier in the case to substantiate a critical element of his claim,
coupled with his last-minute filing of the materials necessary to do so, remain the proximate cause
of delayed resolution. Petitioner will be afforded a reasonable opportunity to respond to the
additional expert report as well. A reasoned determination of the timing issue is most likely if all
parties have had a full and fair opportunity to make their respective cases.

         Petitioner has also maintained10 that I am constrained by the Court’s Review Order to
decide entitlement based solely on the record before me, and therefore cannot allow Respondent
to file his own expert report at this point. See Status Report, dated March 16, 2018 (ECF No. 115).

10
  After the issuance of the Court’s Review Order, I held a status conference with the parties to discuss the best means
of proceeding. See non-pdf Scheduling Order, dated March 12, 2018. At the time, I informed Petitioner of my
preliminary view that I should permit Respondent to file an expert report before I decided entitlement in the matter
again. Petitioner objected, however, to my proposal, as indicated in his March 16 th Status Report.


                                                         14
Such a reading of the Review Order is too narrow. The Order required me to resolve Respondent’s
motion to dismiss by applying the proper evidentiary standard, and to so act in the 90-day period
defined by the Vaccine Act and Rules upon remand. See Rule 28(b).11

        I have done precisely as ordered – and am now denying a summary disposition of this case
in favor of either party. The Review Order does not state that I am to determine entitlement based
only on the record as it stands, or to close the record to additional proof. I have in fact found that
I cannot decide the case at this time without evidentiary inputs from Respondent, consistent with
my discretion and in accordance with what has occurred in many other Program cases – even after
trial and even after a decision has issued. Declining to decide this case at the present, before an
entitlement hearing has been held on the disputed matter, arguably constitutes stronger grounds
for the obtaining of additional evidence. Fairness must be a two-way street in Vaccine Program
cases, and concerns for fairness compel me, consistent with Vaccine Rule 3(b), to provide
Respondent the same opportunities that Petitioner has obtained, and that Program claimants are
allowed frequently.




11
  I acknowledge that the Court’s Review Order specifically directs me to issue a “new entitlement decision,” and thus
my present disposition, taken literally, does not accomplish this – but only if the term “decision” is given the technical
meaning employed in the Vaccine Program for the reasoned determinations of special masters. In the Program,
“decisions” trigger issuance of judgments by the Clerk of the Court, and must therefore involve either the denial of
entitlement (in effect, a judgment awarding $0) or the awarding of a specified sum of damages. See 42 U.S.C. §300aa-
12(d)(3)(A);Vaccine Rule 10. Because I am no longer granting the relief requested by Respondent (dismissal of the
claim), however, I am only “ruling” on entitlement, and thus not yet issuing a decision. At the same time, granting
Petitioner’s counter-request for a favorable ruling on the record would also not constitute a “decision” until damages
were resolved (a matter than in my experience can take a year or more) – and would therefore be just as much a
technical abrogation of the Review Order. My disposition of this matter on remand is consistent with the spirit of the
Court’s Review Order (parsing the Court’s usage herein of the word “decision” for its more broadly-understood
meaning, i.e. to resolve an outcome of a disputed matter).

 This raises an additional concern – the fact that my disposition of Respondent’s pending motion will not result in the
complete resolution of this case in the 90-day period prescribed for special masters to act upon remand under Rule
28(b). Review Order at 12. By permitting Respondent the time to obtain an expert report and setting the matter for
hearing, the case is unlikely to be resolved in so short a period. But there are two countervailing considerations that
suggest this too is not an abrogation of my responsibilities in carrying out the mandate of the Court’s Review Order.
First, the present ruling is being issued within 90 days of the Court’s February 27, 2018 Review Order (a time period
that would expire no sooner than May 29, 2018). Second, there is persuasive dicta from other Court decisions
observing that “the Vaccine Act does not identify any consequences for failure to act within the ninety-day remand
period,” and therefore parties to a litigation, in consultation with the relevant special master, can agree to extend the
period if to do so would be in the “interests of justice” and that the Court of Federal Claims would likely support such
a determination. See Hodge v. Sec’y of Health & Human Servs., No. 09-453V, slip. op. at 1-2 (Fed. Cl. Nov. 9, 2015)
(emphasis added), citing Paluck v. Sec’y of Health & Human Servs., 111 Fed. Cl. 160,165-66 (2013).

If Petitioner deems the 90-day time period to require total and complete resolution of his claim, and is therefore
unwilling to accede to the necessity of this matter taking more time to resolve, he may so argue in another motion for
review, after I have resolved entitlement (and assuming I do so against him), or in response to a motion to the Court
by Respondent to extend the 90-period.


                                                           15
                                           CONCLUSION

        Petitioner has now offered adequate evidentiary support for his claim that the 41-day onset
period for his brachial neuritis was medically acceptable, thereby removing the former grounds
upon which I dismissed his claim, and causing me to DENY Respondent’s Motion. However, I
cannot otherwise rule on whether Petitioner has carried his burden of proof on the record as it
stands, and therefore do not decide entitlement at this time in his favor either.

        The parties shall contact chambers and request a status conference, at which time a
schedule for Respondent’s filing of an expert report, as well as a final response to that report from
Petitioner’s expert(s) and then trial of this matter, shall be discussed.
