Ava Chang v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2025)
Case summary [AI summaries can sometimes make mistakes]
On August 1, 2023, Ava Chang filed a petition alleging that a tetanus/Tdap vaccination administered on November 23, 2022 caused a shoulder injury related to vaccine administration. The existing record reflects two concurrent vaccinations on that date.
Respondent denied that Ms. Chang sustained a Table SIRVA, denied that Tdap caused her alleged SIRVA or any other injury, and denied that her current condition was vaccine-related.
The public stipulation does not describe the first symptom, timing, treatment, imaging, injections, therapy, or lasting limitations. The parties filed a joint stipulation on October 27, 2025.
Chief Special Master Brian H. Corcoran adopted it on October 28, 2025 and awarded $12,500.00 as a lump sum through counsel's IOLTA account.
