Sharon Matzek v. HHS - Influenza, Guillain-Barre syndrome (GBS) (2025)
Case summary [AI summaries can sometimes make mistakes]
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.
