Ryan Middleton v. HHS - Influenza, shoulder injury related to vaccine administration (SIRVA) (2026)

Ryan Middleton filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging he suffered a shoulder injury related to vaccine administration (SIRVA) as a result of an influenza vaccination received on September 25, 2024. He further alleged that he suffered the residual effects of his condition for more than six months.

The respondent conceded that the petitioner's alleged injury is consistent with SIRVA as defined by the Vaccine Injury Table, noting that he had no prior history of shoulder issues, pain occurred within forty-eight hours after vaccination, and pain and reduced range of motion were limited to the vaccinated shoulder. 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 of record, the Chief Special Master found that Petitioner is entitled to compensation.
