Andrew Diaz v. HHS - Tdap, left-sided shoulder injury related to vaccine administration (SIRVA) (2026)

Andrew Diaz filed a petition for compensation under the National Vaccine Injury Compensation Program on February 10, 2026, alleging a left-sided shoulder injury related to vaccine administration (SIRVA) resulting from a Tdap vaccination received on May 17, 2023. He further alleged that he suffered residual effects for more than six months.

The Respondent conceded that Petitioner is entitled to compensation, stating that his injury is consistent with SIRVA as defined by the Vaccine Injury Table. Specifically, the Respondent noted that Petitioner had no prior shoulder issues, the pain occurred within 48 hours post-vaccination, was limited to the vaccinated shoulder, and no other condition explained the pain.

The Respondent also agreed that Petitioner suffered residual effects for more than six months and satisfied all legal prerequisites for compensation. Based on the Respondent's concession and the evidence, the Chief Special Master found Petitioner entitled to compensation.
