The former FDA commissioner says a main difference between the agency recommendations is FDA guidance clearly allows boosters for all healthcare workers while the CDC guidance is more restrictive.
"I can’t remember a precedent where the CDC’s advisory panel differed this starkly from the FDA’s recommendation…I think this is far more explicit than what I remember in the past… This is a very explicit deviation from the FDA’s recommendation. The FDA very clearly, the advisory panel wanted to scope in people 18 and above who are at risk from severe covid because of occupational exposure which would include all the healthcare providers in the nation. I think that was one of the reasons why FDA ultimately came down where they did… Under the CDC’s recommendation, if it is in fact put into effect, a healthcare provider wouldn’t be eligible for a booster unless they have an underlying medical condition.”
