Overview
- Prasad stepped down on July 29 after less than three months overseeing CBER and serving as FDA chief medical and scientific officer.
- A spokesperson for Health and Human Services said Prasad chose to return to California to be with his family and avoid distracting the agency as it faced intensified White House scrutiny.
- He implemented tighter approval criteria for Moderna and Novavax COVID-19 vaccines, limiting authorizations to seniors and immunocompromised groups.
- He paused shipments of Sarepta’s Duchenne muscular dystrophy therapy Elevidys after patient deaths, a restriction the FDA has since eased pending more safety data.
- Prasad’s emphasis on scientific rigor drew acclaim from transparency advocates but provoked criticism from biotech investors, FDA career staff and conservative commentators.
