Renee Byndloss v. HHS - Tdap, Shoulder injury related to vaccine administration (SIRVA) (2026)

Renee Byndloss filed a petition alleging that she suffered bilateral shoulder injuries related to vaccine administration (SIRVA) after receiving Tdap and MMR vaccines on May 7, 2018. Initially, the case was handled by Chief Special Master Corcoran, who dismissed the claim for a right-sided SIRVA, finding that the MMR vaccine was administered subcutaneously and thus not a basis for a Table SIRVA, and that the Tdap vaccine was administered in the left arm.

The case was then transferred to Special Master Horner. After a fact hearing and further briefing, Special Master Horner found that Renee Byndloss is entitled to compensation for a left-sided Table SIRVA resulting from her Tdap vaccination.

The Special Master determined that the petitioner experienced pain within 48 hours of vaccination and that the pain and reduced range of motion were limited to the left shoulder. However, the petitioner did not establish entitlement for a right-sided SIRVA or a cause-in-fact injury from the MMR vaccine.

A separate order for damages will be issued.
