On August 1, 2024, David Keifrider filed a petition alleging that an influenza vaccination administered in his left shoulder on November 9, 2023 caused a shoulder injury related to vaccine administration. The public stipulation does not provide a detailed medical timeline.

It records that Mr. Keifrider alleged a Table SIRVA lasting longer than six months, while respondent denied that he sustained a Table SIRVA, denied that the flu vaccine caused his alleged shoulder injury or any other injury, and denied vaccine-related sequelae.

Keifrider $42,500.00 in a lump sum for all damages available under the Vaccine Act. Payment was to be made by ACH deposit to counsel's IOLTA account for prompt disbursement.

Mr. Keifrider was represented by Joseph C.

Shannon.
