Theresa Cassaboom v. HHS - Tdap, shoulder injury related to vaccine administration (SIRVA) (2026)

Theresa Cassaboom filed a petition for compensation under the National Vaccine Injury Compensation Program, alleging that she suffered a Table shoulder injury related to vaccine administration (SIRVA) as a result of a Tdap vaccination she received on June 19, 2024. She stated that the vaccine was administered in the United States, that she suffered residual effects for more than six months, and that she had no prior award or settlement for her injury.

Respondent denied that petitioner sustained a SIRVA Table injury or any other injury caused by the vaccine. The parties filed a joint stipulation agreeing that a decision should be entered awarding compensation.

Chief Special Master Corcoran found the stipulation reasonable and adopted it as the decision awarding damages. Theresa Cassaboom was awarded a lump sum of $35,000.00 for all items of damages.
