Nancy Smacchi v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2025)

Nancy Smacchi filed a petition for compensation under the National Vaccine Injury Compensation Program on March 5, 2025. She alleged that a tetanus diphtheria and pertussis (Tdap) vaccination received on July 22, 2022, caused a shoulder injury related to vaccine administration (SIRVA), which is a Table Injury.

Smacchi further stated that her injury resulted in residual effects lasting more than six months and that she had not received any prior award or settlement for this injury. The respondent, the Secretary of Health and Human Services, filed a Rule 4(c) report on February 28, 2025, conceding that Smacchi is entitled to compensation.

The respondent agreed that her injury was consistent with SIRVA as defined by the Vaccine Injury Table and that all other legal requirements for compensation had been met. Based on the respondent's concession and the evidence, the Chief Special Master found that Nancy Smacchi is entitled to compensation, with the damages to be determined in a subsequent decision.
