Despite some concerns from a few members, the Advisory Committee on Immunization Practices unanimously approved recommendations to the CDC that boosters be made available to those wanting them. The advisory committee recommended that a single COVID-19 vaccine booster dose be given six months or more after completing an mRNA primary series in the same risk group for whom the CDC recommended a booster dose of Pfizer Inc-Biontech SA’s vaccine. The CDC presented data to the committee that the single mRNA COVID-19 vaccine dose be given to those age 65 and older, for those at least 18 years old and reside in long-term-care settings, and also for those ages 50 to 60 with certain underlying medical conditions.
