The U.S. Food and Drug Administration said on Wednesday it will hold a meeting of experts on May 22 to discuss COVID-19 vaccine recommendations for the upcoming immunization campaign. The meeting comes after the appointment of Martin Makary as FDA commissioner.

The advisory committee meeting is an important step in the process of readying boosters for the fall and winter season, but will take place amid newly imposed scrutiny of COVID shots.

Dr. Marty Makary, chief of the FDA, has expressed doubts about the agency approving the COVID-19 vaccine for winter, stating that additional data is still required.
