FDA scientists strike skeptical tone on need for Covid-19 vaccine booster at this time, likely fueling debate
Food and Drug Administration scientists have expressed skepticism about the need for additional doses of Pfizer’s Covid-19 vaccine for all people who have received it.
The assessment by the agency’s staff, included in documents released Wednesday, sets up a high-stakes debate over who will need an additional booster dose — and when they will need it — at the meeting of experts being convened by the Food and Drug Administration on Friday.
