Who Will Be the Next F.D.A. Chief?

One month into his presidency, President Biden still has not named a candidate to head the Food and Drug Administration, a critical position at a time when new vaccines and coronavirus treatments are under the agency’s review.

The glaring vacancy lags behind the president’s selections of most other top government health posts, and has spurred a public lobbying campaign by supporters of the two apparent front-runners, Dr. Joshua Sharfstein, a former high-ranking F.D.A. official and Dr. Janet Woodcock, the acting commissioner.
