Kristy Anderson v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2026)

On January 10, 2023, Kristy Anderson filed a petition alleging that a tetanus, diphtheria, and acellular pertussis (Tdap) vaccination administered on May 6, 2021 caused a shoulder injury related to vaccine administration. She alleged residual effects lasting more than six months and no prior civil recovery.

Respondent denied that Ms. Anderson sustained a SIRVA Table injury, denied that the Tdap vaccine caused her alleged shoulder injury or any other injury, and denied that her current condition was a sequela of a vaccine-related injury.

Because the case was resolved by stipulation, the public decision does not describe the onset event, clinical course, imaging, injections, therapy, or expert evidence. On March 18, 2026, Chief Special Master Brian H.

Corcoran found the stipulation reasonable and awarded $30,000.00 as a lump sum payable through counsel's IOLTA account for prompt disbursement to Ms. Anderson.
