                          DECISION DENYING COMPENSATION1

       Ms. Rodrigue alleged that the influenza (“flu”) vaccine she received on
November 1, 2016, caused her to develop chronic inflammatory demyelinating
polyneuritis (“CIDP”). Pet., filed Sep. 28, 2017. Ms. Rodrigue asserted that she
started to develop numbness and tingling within a couple of weeks of the
vaccination. Id. ¶ 2. The Secretary of Health and Human Services disputes these
claims. As explained below, Ms. Rodrigue has not established that she is entitled
to compensation.

I.     Procedural History

      Ms. Rodrigue filed her medical records, including records from a
neurologist, Daniel Trahant, who first saw her on March 8, 2017. Exhibit 16 at 4.
The Secretary questioned the accuracy of the history that Dr. Trahant obtained.

       1
         The E-Government Act, 44 U.S.C. § 3501 note (2012) (Federal Management and
Promotion of Electronic Government Services), requires that the Court post this decision on its
website. This posting will make the decision available to anyone with the internet. Pursuant to
Vaccine Rule 18(b), the parties have 14 days to file a motion proposing redaction of medical
information or other information described in 42 U.S.C. § 300aa-12(d)(4). Any redactions
ordered by the special master will appear in the document posted on the website.
Resp’t’s Rep., filed August 3, 2018, at 4 n.3 and 10. Thus, the onset of Ms.
Rodrigue’s symptoms was a key factual dispute.

       After the Secretary’s report, Dr. Trahant wrote a letter to Ms. Rodrigue’s
attorney, stating that “After reviewing [the affidavits of her husband and daughter]
and the documentation of the influenza vaccine administered on November 1,
2016, . . . it is my opinion that, more likely than not, the influenza vaccine was the
cause of Ms. Rodrigue developing chronic inflammatory demyelinating
polyneuropathy.” Id. at 2. Dr. Trahant also sought to correct notations he made in
Ms. Rodrigue’s medical records, based entirely on contrary information provided
in the affidavits. Id. at 1-2. These original notations included inaccuracies related
to the vaccination itself, as well as the timing of previous symptoms and diagnoses.
Most importantly, the corrections contained in his letter relied only on information
supplied by Ms. Rodrigue and her fact witnesses.

        A hearing was set to determine onset, as well as to address challenges Ms.
Rodrigue made regarding the accuracy of part of her primary care physician Dr.
Acosta’s records. The hearing was held on October 16-17, 2019, in New Orleans,
Louisiana. The undersigned found that Ms. Rodrigue began experiencing a decline
in neurologic function beginning on January 30, 2017. The undersigned also found
Dr. Acosta’s records to be accurate, and Dr. Trahant’s records to contain various
inaccuracies. Furthermore, the undersigned found Dr. Trahant’s August 15, 2018
letter to hold little evidentiary weight because Dr. Trahant prepared it in
anticipation of litigation, and accepted assertions obtained solely from Ms.
Rodrigue and her fact witnesses. Ruling Finding Facts, 2019 WL 7560056 (Fed.
Cl. Spec. Mstr. Oct. 22, 2019).

       Following this fact ruling, Ms. Rodrigue first sought to obtain an expert
report and then decided not to retain an expert and instead to move for a ruling on
the record. In a status conference held on May 11, 2020, the parties confirmed that
they do not intend to submit any more filings. Thus, this matter is ripe for
consideration.

II.   Standards for Adjudication

      Petitioners are required to establish their cases by a preponderance of the
evidence. 42 U.S.C. § 300aa–13(1)(a). The preponderance of the evidence
standard requires a “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 v. Sec’y of

                                             2
Health & Human Servs., 592 F.3d 1315, 1322 n.2 (Fed. Cir. 2010) (citations
omitted).

      The special master may not rule in a petitioner’s favor based on petitioner’s
claim alone. 42 U.S.C. § 300aa-13(a)(1); Shyface v. Sec’y of Health & Human
Servs., 165 F.3d 1344, 1349 (Fed. Cir. 1999). Instead, the causation assertion must
be substantiated by some additional medical records or medical opinion. Shyface,
165 F.3d at 1349.

      Special masters retain significant discretion in deciding issues of fact,
including making credibility determinations. Burns v. Sec’y of Health & Human
Servs., 3 F.3d 415, 416-17 (Fed. Cir. 1993). Furthermore, these factual findings
once decided, are controlling to the extent that they are relevant to the entitlement
determination. Id. at 17.

III.   Analysis

      Ms. Rodrigue’s claim fails because her lone source of expert support for the
contention that her flu vaccine caused her CIDP relies on assertions not endorsed
by the Findings of Fact. Ms. Rodrigue asserted that her CIDP symptoms began
within a few weeks of her flu vaccination on November 1, 2016. Pet’r’s Br. at 1.
However, this conclusion was supported only by fact witness affidavits. The
undersigned found that conflicting information from doctors’ appointments
following her vaccination, in which no notations of these symptoms were made,
outweighed the testimony provided by Ms. Rodrigue and her family members.
The undersigned ultimately determined an onset date of January 30, 2017. Ruling
Finding Facts, 2019 WL 7560056, at *1.

       Dr. Trahant used Ms. Rodrigue’s asserted onset time frame (that is, within
the first few weeks following her vaccination) as the basis for his opinion that her
flu vaccination caused CIDP. This is in direct conflict with the January 30, 2017
onset date found in the Ruling Finding Facts. Therefore, given that this expert
opinion relies on uncredited assertions, it is not a relevant or reliable source of
evidence for Ms. Rodrigue’s claim. See Burns v. Sec’y of Health & Human
Servs., 3 F.3d 415, 416-17 (Fed. Cir. 1993). Dr. Trahant’s letter is the only expert
evidence put forth, and Ms. Rodrigue has elected not to provide additional expert
support. Therefore, because the undersigned may not rule in a petitioner’s favor
based on a petitioner’s contentions alone, without additional medical expert or
medical record support, 42 U.S.C. § 300aa-13(a)(1), the undersigned finds that Ms.
Rodrigue has not met her burden in showing that her flu vaccination caused her
CIDP.

                                              3
IV.    Conclusion

       Because Ms. Rodrigue’s sole source of expert support for causation between
her vaccination and CIDP relied on assertions in direct conflict with the Ruling
Finding Facts, the undersigned finds that Ms. Rodrigue has not proven by
preponderant evidence that the flu vaccination caused her CIPD. The Clerk’s
Office is instructed to enter judgment in accord with this decision unless a motion
for review is filed. 2

       IT IS SO ORDERED.
