Public Readiness and Emergency Preparedness Act
The Public Readiness and Emergency Preparedness Act (commonly referred to as the PREP Act or PREPA), passed by the United States Congress and signed into law by President of the United States George W. Bush in December 2005 (as part of Public Law 109-148), is a controversial tort liability shield intended to protect pharmaceutical manufacturers from financial risk in the event of a declared public health emergency. The part of the PREP Act that actually affords such protection is now codified at 42 U.S.C. § 247d-6d.
