Pres. George W. Bush signs the PREP Act

This act is part of HR 2863.

This federal act was passed as part of the Department of Defense Appropriations bill for FY 06 (Division C of H.R. 2863; P.L. 109-148) and signed into law on December 30, 2005. It provides immunity from lawsuits under state and federal law for manufacturers and distributors of pandemic and epidemic products (including vaccines) and security countermeasures, in the event that the Health and Human Services Department (HHS) secretary declares a public health emergency as a result of a disease or other health condition. The only exception to this immunity is in the case of “willful misconduct.”
