Two prominent scientists who recently retired from the U.S. Food and Drug Administration are blasting the Biden administration’s plans to approve third, booster doses of COVID-19 vaccines to most U.S. residents. In a scathing critique published in the British medical journal The Lancet, Philip Krause and Marion Gruber write, “Current evidence does not appear to show a need for boosting in the general population, in which efficacy against severe disease remains high. … The limited supply of these vaccines will save the most lives if made available to people who are at appreciable risk of serious disease and have not yet received any vaccine.”
