Derek Troccia v. HHS - Tdap, shoulder injuries related to vaccine administration (SIRVA) (2025)

On March 29, 2024, Derek Troccia filed a petition seeking compensation after a tetanus, diphtheria, and acellular pertussis (Tdap) vaccination administered on December 22, 2021. He alleged shoulder injuries related to vaccine administration and residual effects lasting more than six months.

Respondent denied that Mr. Troccia had sustained a Table SIRVA, denied that the Tdap vaccine caused his alleged shoulder injury or any other injury, and denied that any current condition was a sequela of a vaccine-related injury.

The public decision is a stipulation decision, so it does not describe the first symptom, onset interval, medical visits, imaging, treatment, expert opinions, or a biological mechanism beyond the asserted SIRVA theory. On September 30, 2025, Chief Special Master Brian H.

Corcoran found the parties' stipulation reasonable and adopted it as the Court's decision. Mr.

Troccia received a lump sum of $59,250.00, paid through counsel's IOLTA account, representing all damages available under Section 15(a). He was represented by Heather Varney Menezes of Shaheen & Gordon, P.A.
