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

Michelle Ripoll filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging she suffered a shoulder injury related to vaccine administration (SIRVA) following receipt of a tetanus-diphtheria-acellular pertussis (Tdap) vaccine on August 9, 2024. She claimed residual effects for more than six months.

The respondent conceded that Petitioner is entitled to compensation for a Table SIRVA, noting that she had no prior shoulder issues, the pain occurred within 48 hours of vaccination, and symptoms were limited to the vaccination side.
