Service Restoration Act This bill prohibits the use of federal funds to require a member of the Armed Forces to receive a COVID-19 vaccination. The bill also prohibits adverse action (e.g., punishment) being taken against a member of the Armed Forces solely on the basis that the member refuses to receive a COVID-19 vaccination. Individuals who were involuntarily separated from the Armed Forces solely on the basis of their refusal to receive a COVID-19 vaccination must be reinstated in the grade they held prior to the separation. In computing retired or retainer pay, the military department concerned must include the time between the involuntary separation and reinstatement of the individual. The military department concerned must expunge adverse actions or references to involuntary separation related to the refusal to receive a COVID-19 vaccination from an individual's service record.
