This bill amends title 38 of the United States Code to establish a new presumption of service-connection for specific diseases affecting service members. This presumption applies if these diseases manifest within one year in individuals who received a COVID-19 vaccine under orders between August 24, 2021, and January 10, 2023. The legislation aims to ensure that such conditions are considered incurred or aggravated during active military service for the purpose of veterans' benefits, even without direct service records. The diseases covered under this presumption include myocarditis , pericarditis , thrombosis with thrombocytopenia syndrome , and Guillain-Barre Syndrome . The Secretary of Veterans Affairs is also authorized to add other diseases if a positive association with the COVID-19 vaccine is determined, with a requirement to notify Congress of such additions. Additionally, the bill mandates the Secretary to submit detailed reports every 60 days for four years to Congress, outlining the total number and status of claims related to these vaccine-associated diseases, and to make these reports publicly accessible.
