The five-year extension, signed by Health and Human Services (HHS) Secretary Xavier Becerra on Dec. 11, continues a policy first implemented during the pandemic under then-President Donald Trump. It is one of the longest liability protections in the history of the Public Readiness and Emergency Preparedness (PREP) Act. Proponents argue that the protections are essential for fostering innovation and maintaining public health readiness, but critics contend they leave vaccine-injured individuals without recourse and could limit future administrations’ ability to enact significant policy changes.
