Health-care providers, frontline responders, manufacturers, distributors, and others involved in the fight against COVID-19 should be comforted by the legal protections afforded by the Public Readiness and Emergency Preparedness Act (PREP Act), 42 U.S.C. §247d-6d. A review of the PREP Act and related Amendments illustrates the expanding shield the PREP Act can provide against COVID-19 related litigation. While the U.S. Department of Health and Human Services (HHS) continues to expand coverage of the PREP Act's broad-based, retroactive immunity, the case law is in its infancy and is at times inconsistent, highlighting the importance for "covered persons" to keep abreast of future developments.
