Dr. Marion Gruber and Dr. Philip Krause are apparently resigning from the Food and Drug Administration in protest over the Biden administration’s push for a COVID-19 vaccine booster.

Gruber is the director, and Krause the deputy director of the FDA’s Office of Vaccines Research and Review at FDA’s Center for Biologics Evaluation and Research. In a recent article in the British medical journal the Lancet, they write, “Current evidence does not … appear to show a need for boosting in the general population.”
