In a 58-second video posted on the social media site X, Kennedy said he removed COVID-19 shots from Centers for Disease Control and Prevention’s recommendations for those groups. No one from the CDC was in the video, and CDC officials referred questions about the announcement to Kennedy and the U.S. Department of Health and Human Services.

U.S. health officials, following recommendations by infectious disease experts, have been urging annual COVID-19 boosters for all Americans ages 6 months and older.

A CDC advisory panel is set to meets in June to make recommendations about the fall shots. Among its options are suggesting shots for high-risk groups but still giving lower-risk people the choice to get vaccinated.
