AI-assisted case summary:
On April 24, 2025, Sharon Matzek filed a petition alleging that an influenza vaccine administered on October 6, 2023 caused Guillain-Barre syndrome. The public ruling identifies her as an adult petitioner but does not state her exact age.

Respondent conceded entitlement in a Rule 4(c) report filed on October 23, 2025. The concession stated that Ms. Matzek's illness met the Vaccine Injury Table requirements for GBS because onset occurred within the required 3-to-42-day period after vaccination and no apparent alternative cause was identified. The public ruling does not describe her first neurologic symptoms, hospitalization, electrodiagnostic testing, lumbar puncture, treatment, or residual deficits.

On October 23, 2025, Chief Special Master Corcoran found Ms. Matzek entitled to compensation. Damages remained to be determined.

Theory of causation field:
Adult petitioner; influenza vaccine October 6, 2023; Table GBS. ENTITLEMENT GRANTED, DAMAGES PENDING. Respondent conceded onset within 3-42 days and no apparent alternative cause. Public entitlement ruling lacks clinical timeline/treatment details. CSM Corcoran October 23, 2025. Petition filed April 24, 2025.

RULING ON ENTITLEMENT1
On April 24, 2025, Sharon Matzek filed a petition for compensation under the
National Vaccine Injury Compensation Program, 42 U.S.C. §300aa-10, et seq.2 (the
“Vaccine Act”). Petitioner alleged that she suffered Guillain-Barré Syndrome (“GBS”), a
defined Table injury, or in the alternative caused-in-fact injury, after receiving an influenza
(“flu”) vaccine on October 6, 2023. Petition at 1, ¶¶ 2, 32. Petitioner also alleged that she
received the vaccine within the United States, that she suffered the residual effects of her
GBS for more than six months, and that neither she nor any other party has filed a civil
action or received compensation for her GBS, alleged as vaccine caused. Id. at ¶¶ 2, 31,
1 Because this Ruling contains a reasoned explanation for the action taken in this case, it must be made
publicly accessible and will be posted on the United States Court of Federal Claims' website, and/or
at https://www.govinfo.gov/app/collection/uscourts/national/cofc, in accordance with the E-Government
Act of 2002. 44 U.S.C. § 3501 note (2018) (Federal Management and Promotion of Electronic Government
Services). This means the Ruling will be available to anyone with access to the internet. In accordance
with Vaccine Rule 18(b), Petitioner has 14 days to identify and move to redact medical or other information,
the disclosure of which would constitute an unwarranted invasion of privacy. If, upon review, I agree that
the identified material fits within this definition, I will redact such material from public access.

33-34. The case was assigned to the Special Processing Unit of the Office of Special
Masters.
On October 23, 2025, Respondent filed his Rule 4(c) report in which he concedes
that Petitioner is entitled to compensation in this case. Respondent’s Rule 4(c) Report at
1. Specifically, Respondent has concluded “that [P]etitioner has satisfied the criteria set
forth in the Vaccine Injury Table (“Table”) and Qualifications and Aids to Interpretation
(“QAI”), which afford [P]etitioner a presumption of causation.” Id. at 7.
In view of Respondent’s position and the evidence of record, I find that
Petitioner is entitled to compensation.
IT IS SO ORDERED.
