Isak Ladegaard v. HHS - Tdap, left shoulder injury related to vaccine administration (SIRVA) (2026)

Isak Ladegaard filed a petition alleging a left shoulder injury related to vaccine administration (SIRVA) after receiving a Tdap vaccine on October 31, 2022. He also received an influenza vaccine on the same day.

The injury was alleged to be a Table Injury, requiring residual effects lasting longer than six months. The respondent contested the duration of the injury.

The court found that Mr. Ladegaard likely suffered residual effects of his SIRVA for more than six months, meeting the severity requirement.

The court also found that he met the other criteria for a Table SIRVA, including no prior history of shoulder issues that would explain the symptoms, pain occurring within 48 hours of vaccination, and pain and limited range of motion confined to the left shoulder. He is entitled to compensation.

The court noted that the compensation for past pain and suffering would likely not be significant due to minimal conservative treatment and good, though temporary, pain relief from a steroid injection.
