The U.S. Centers for Disease Control and Prevention recommended messenger RNA vaccines made by Moderna Inc. and Pfizer Inc. for use in adults over Johnson & Johnson’s shot, which has been linked to rare but serious blood clots.

All 15 members of CDC’s Advisory Committee on Immunization Practices voted in favor of the recommendation Thursday after U.S. regulators announced revisions to the shot’s fact sheet to warn of the rare clotting syndrome. CDC Director Rochelle Walensky signed off on the advice.
