A panel of outside experts advising the US Centers for Disease Control and Prevention (CDC) on Wednesday voted to recommend booster shots of Pfizer Inc and BioNTech SE’s Covid-19 vaccine be made available to 12- to 15-year-olds.
The CDC’s Advisory Committee on Immunization Practices (ACIP) voted 13 to one to recommend that the US health agency support booster shots for those aged 12 to 15 at least five months after their second dose.
The panel also said the CDC should strengthen its recommendation for boosters ages 16 and 17. The agency had previously made the shots available to those teenagers, but had stopped short of suggesting that all of them should receive the additional jab.
Covid-19 cases in the US have hit record levels in recent days due to the fast spreading Omicron variant of the virus. Infection rates are surging as many workers and school children return from holiday vacations, raising the prospect of overwhelmed health systems as well as closed businesses and schools.
“Covid is overwhelming our hospitals and our children’s hospitals,” said panel member Katherine Poehling, a professor at Wake Forest School of Medicine. “This is a tool we need to use, and help our children through this pandemic.”
Data from Israel’s health ministry presented at the meeting suggested that vaccinated children aged 12 to 15 who were five to six months past their second dose were being infected at the same rate as unvaccinated kids by the Omicron variant of the virus. After receiving a booster shot, the infection rate dropped sharply, according to the data.
Peter Marks, a top regulator at the US Food and Drug Administration, said that it is reasonable to extend the boosters down to 12- to 15-year-olds given the current surge in cases.
The FDA authorised Pfizer’s Covid-19 booster for 12- to 15-year-olds for the age group on Monday, but the CDC needs to sign off before the shots can be administered. CDC director Rochelle Walensky is expected to weigh in quickly, allowing the boosters to begin as soon as this week.
Some scientists have expressed concerns about the booster shots due to rare cases of heart inflammation called myocarditis that have been linked to both the Pfizer-BioNTech and Moderna vaccines, particularly in young men.
While there is limited data on myocarditis after booster doses for ages 12 to 15, the FDA has said evidence from both the US and Israel indicates that the risk of myocarditis in men aged 18-40 is significantly lower after booster shots than after the second vaccine dose.
Only two cases of myocarditis were reported in Israel among 44,000 adolescents aged 12 to 15 who received a third dose of the Pfizer-BioNTech vaccine, the Israeli health ministry said on Wednesday.
