U.S. Representative Thomas Massie, a Kentucky Republican, has introduced the PREP Repeal Act (H.R. 4388), legislation that would revoke the 2005 Public Readiness and Emergency Preparedness Act’s liability shield for manufacturers of vaccines, drugs and medical devices used during public-health emergencies. Massie said the proposal aims to restore individuals’ ability to sue over alleged injuries related to COVID-19 vaccines and other pandemic countermeasures. The PREP Act’s protections, extended by the Department of Health and Human Services, are currently slated to remain in force until 2029. The bill would eliminate those federal safeguards, exposing pharmaceutical companies to state-law tort claims. Similar efforts to curtail the PREP Act have previously stalled in Congress, and H.R. 4388 faces uncertain prospects in the Republican-controlled House and the Democratically controlled Senate.
