Daniel Brennan v. HHS - Influenza, shoulder injury related to vaccine administration (SIRVA) (2026)

On April 11, 2025, Daniel Brennan filed a petition alleging that an influenza vaccine administered on October 18, 2023 caused a shoulder injury related to vaccine administration. Respondent conceded entitlement, agreeing that the record satisfied the Table SIRVA criteria.

Mr. Brennan had no prior pain, inflammation, or dysfunction in the affected shoulder that would explain the post-vaccination findings; pain began within 48 hours; pain and reduced range of motion were limited to the vaccinated shoulder; no other condition better explained his symptoms; and the injury lasted more than six months.

Chief Special Master Brian H. Corcoran found entitlement on October 28, 2025.

On January 5, 2026, he adopted respondent's damages proffer and awarded Mr. Brennan $112,500.00 for pain and suffering as a lump sum.
