In a paper published days before the advisory committee meeting, a leading group of scientists said available data showed vaccine protection against severe disease persists, even as the effectiveness against mild disease wanes over time. The authors, including two high-ranking FDA officials and multiple scientists from the World Health Organization, argued Monday in the medical journal The Lancet that widely distributing booster shots to the general public is not appropriate at this time. In outlining plans last month to start distributing boosters as early as next week, administration officials cited three CDC studies that showed the vaccines’ protection against Covid diminished over several months. Senior health officials said at the time they worried protection against severe disease, hospitalization and death “could” diminish in the months ahead, especially among those who are at higher risk or were vaccinated during the earlier phases of the vaccination rollout. Before the vote, some committee members said they were concerned that there wasn’t enough data to make a recommendation, while others argued third shots should be limited to certain groups, such as people over age 60 who are known to be at higher risk of severe disease. Some members raised concerns about the risk of myocarditis in younger people, saying more research is needed.
