Lindsay A. Mack v. HHS - Influenza, left shoulder injury related to vaccine administration (SIRVA) (2026)

Lindsay A. Mack filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging she suffered a left shoulder injury related to vaccine administration (SIRVA) from an influenza vaccine received on May 6, 2019.

She is a dentist. The respondent argued that the onset of her pain was not within 48 hours of vaccination, citing medical records.

However, the Special Master found that while initial medical records were general, Petitioner's subsequent emails and affidavits, along with medical records noting onset on May 7, 2019, provided preponderant evidence that her pain began within 48 hours of vaccination. The Special Master also noted that the injury met the Table criteria for SIRVA and that Petitioner satisfied the other requirements for entitlement, including the duration of injury and lack of prior award or settlement.

Therefore, Petitioner was found entitled to compensation, and a separate damages order will be issued.
