Dr. Vinay Prasad, a prominent UCSF oncologist and outspoken critic of the U.S. government’s past pandemic policies, has been reinstated at his senior post at the Food and Drug Administration less than two weeks after resigning under pressure.

Overview

  • Dr. Vinay Prasad resumed leadership of the FDA’s Center for Biologics Evaluation and Research on August 9 at the agency’s request, less than two weeks after his July 30 resignation.
  • His July resignation followed controversy over tighter COVID-19 vaccine rules and the FDA’s pause and restart of Sarepta Therapeutics’ Duchenne muscular dystrophy gene therapy.
  • George Tidmarsh served as acting director of the biologics center during Prasad’s absence.
  • Commissioner Marty Makary had appointed Prasad in May to enforce stricter standards for vaccines and gene therapies as FDA chief medical and scientific officer.
  • The rapid reversal highlights ongoing debates over political pressure and the FDA’s scientific autonomy.
