Tiffany McKnight v. HHS - Influenza, left shoulder injury related to vaccine administration (SIRVA) (2025)

Tiffany McKnight filed a petition alleging a left shoulder injury related to vaccine administration (SIRVA) following an influenza vaccine on October 7, 2019. The respondent initially contested entitlement, arguing the vaccine was administered in the right arm and that symptom onset did not occur within 48 hours.

The court found that the evidence, including petitioner's consistent reporting and the general unreliability of automated vaccination records, supported that the vaccine was administered in the left shoulder. The court also found that petitioner provided preponderant evidence that her shoulder pain began within 48 hours of vaccination, satisfying the Table criteria for SIRVA onset.

However, the court noted that another objection regarding reduced range of motion remained and could potentially lead to denial. The court encouraged settlement discussions, noting that the evidence suggested the pain was not severe and any award would likely be modest.

The case is proceeding, with entitlement to the left shoulder injury granted pending further evaluation of damages.
