evidence: The COVID-19 public health emergency’s end doesn’t affect the U.S. Food and Drug Administration’s authority to issue new emergency use authorizations related to the novel coronavirus. That’s because a public health declaration and an emergency use authorization declaration are issued under two distinct laws. Although the Health and Human Services secretary ended the public health emergency in May 2023, the emergency use authorization declaration, last amended in March 2023, remains in effect, as COVID-19 remains a potential threat for a public health emergency.
