The agency also recommended that some immunocompromised children ages 5 to 11 receive an additional primary vaccine shot 28 days after the second shot, matching the guidance for similar people 12 and older. Pfizer’s vaccine is the only one authorised for paediatric use in the United States.
The endorsements come on the heels of the authorisation of the same steps by the Food and Drug Administration on Monday.
The FDA also cleared 12- to 15-year-olds to receive boosters of the Pfizer-BioNTech vaccine. The CDC’s vaccine advisory committee is set to meet Wednesday to discuss whether to recommend that step.
The CDC and the FDA share responsibility for setting the nation’s vaccine policy, and have worked to present a unified front in their reviews of booster shots. If the advisory committee does follow the FDA’s lead, the CDC’s director, Dr Rochelle P Walensky, is expected to quickly sign off on the recommendation.
The moves come at a time when the fast-spreading omicron variant is infecting record numbers of Americans each day, and many hospitals in the United States are already deluged with COVID-19 patients with the earlier delta variant.
Federal guidance has not changed for when to seek booster shots after initially receiving the Moderna vaccine (six months after the second shot) or the Johnson & Johnson vaccine (two months after the single shot).
More than 70% of people in the United States who are 12 or older have been fully vaccinated, according to the CDC.
In total, at least 1.9 million adolescents between 12 and 15 have tested positive for the virus, according to the CDC. Children who get infected with the coronavirus are less likely to develop serious illness than adults are, but they can still become very sick and even die.
The FDA noted that data from Israel showed no serious safety concerns in thousands of 12- to 15-year-olds who received a third dose of the Pfizer vaccine. There were no reports of myocarditis, a very rare side effect linked to the Pfizer and Moderna vaccines that has been seen mostly in younger men. The condition involves inflammation of muscle tissue in the heart.
