The Food and Drug Administration’s polarizing vaccine chief is leaving the agency after a brief tenure that drew the ire of biotech executives, patient groups and conservative allies of President Donald Trump.

The U.S. Food and Drug Administration's top vaccine official, Vinay Prasad, has left the agency after just three months as Director of the Center for Biologics Evaluation and Research, a government spokesperson said.

Dr. Vinay Prasad had been serving as the FDA's director of the Center for Biologics Evaluation and Research since May, and was later named chief medical and scientific officer.
