Brian O'Sullivan v. HHS - Influenza, Guillain-Barre syndrome (GBS) (2025)
Case summary [AI summaries can sometimes make mistakes]
Brian O'Sullivan filed his petition on October 2, 2023, alleging that an influenza vaccination administered on October 16, 2020 caused Guillain-Barre syndrome. He alleged that the residual effects of the injury lasted more than six months.
O'Sullivan was represented by Leah VaSahnja Durant. Respondent conceded entitlement in a Rule 4(c) report filed on March 11, 2025.
The report stated that O'Sullivan satisfied the Vaccine Injury Table and Qualifications and Aids to Interpretation for a flu/GBS Table injury, and that he satisfied all legal prerequisites for compensation under the Vaccine Act. The public entitlement ruling does not describe O'Sullivan's first neurologic symptom, exact onset day, weakness pattern, reflex findings, hospitalization, cerebrospinal fluid testing, EMG or nerve conduction results, IVIG or plasma exchange treatment, rehabilitation, or remaining limitations.
It also does not provide expert analysis or a detailed biological mechanism. The publicly available story is therefore limited to the conceded Table finding that his GBS followed flu vaccination within the Program's compensable framework.
Chief Special Master Brian H. Corcoran found O'Sullivan entitled to compensation on March 12, 2025.
Damages had not yet been awarded in the staged public text.
