"On Tuesday, two top FDA vaccine regulators resigned — a decision that one former official said was rooted in anger over the agency’s lack of autonomy in the booster planning so far. A current health official said the pair, Marion Gruber and Philip Krause, left over differences with FDA’s top vaccine official Peter Marks. Now the agency is facing a potential mutiny among its staff and outside vaccine advisers, several of whom feel cut out of key decisions and who view the plan to offer boosters to all adults as premature and unnecessary."
