Jacob R. Hildebrandt filed a petition for compensation under the National Vaccine Injury Compensation Program on October 27, 2025.

He alleged that he suffered a left shoulder injury related to vaccine administration (SIRVA) after receiving a tetanus, diphtheria, and acellular pertussis vaccination on August 21, 2023. He further alleged that he suffered residual effects of this condition for more than six months.

The respondent, the Secretary of Health and Human Services, filed a Rule 4(c) report on June 12, 2026, conceding that the petitioner is entitled to compensation. Based on the respondent's concession and the evidence of record, the Chief Special Master found that the petitioner is entitled to compensation.

The case is proceeding to determine damages.
