FDA authorizes bivalent Covid boosters for children 6 months and up
Kids 6 months and older are now eligible to receive Omicron-specific boosters for Covid-19, as US vaccination rates among children remain low.
The FDA on Thursday extended the emergency use authorizations for both Moderna and Pfizer’s updated bivalent vaccines, which include mRNA components of the original coronavirus strain and the BA.4 and BA.5 lineages.
The Omicron BQ.1 and BQ.1.1 strains are currently dominant in the US, accounting for more than 60% of all cases, according to the CDC’s tracker.
The US has seen slow uptake of the new booster shots, and only 12.7% of those 5 years and older have received the updated dose, the CDC reports.
Vaccine rates among very young children are especially low. Despite being eligible for a Covid shot since June, only 6.4% of kids under 2 years old have received at least one dose. Among kids 5 to 11, who have been eligible since last October, 39.2% have received at least one shot.
Most kids who were unvaccinated back in July had a parent who was open to vaccination (59.3%), according to a CDC study conducted over the summer. However, a significant portion of unvaccinated children (37.2%) had a vaccine-hesitant parent.
CDC director Rochelle Walensky said in September that a solid uptake of the bivalent boosters could save thousands of lives and billions of dollars, and the White House has encouraged people to get vaccinated along with their annual flu shot.
“As this virus has changed, and immunity from previous Covid-19 vaccination wanes, the more people who keep up to date on Covid-19 vaccinations, the more benefit there will be for individuals, families and public health by helping prevent severe illnesses, hospitalizations, and deaths,” FDA Commissioner Robert Califf said in a news release this morning.
Bivalent boosters are now available for children 6 months to 5 years old who completed their primary series of the Moderna vaccine at least two months ago, and children 6 months to 4 years old who haven’t yet completed their three-dose primary series of the Pfizer-BioNTech vaccine. The booster will serve as the third 3-µg dose in that case, following two doses of the original Pfizer-BioNTech vaccine.
Kids between 6 months and 4 years old who have already received three doses of the Pfizer-BioNTech vaccine are not yet eligible for a booster. The FDA said the “data to support giving an updated bivalent booster dose for these children are expected in January,” and it has promised to review the data as quickly as possible.
Pfizer said in a statement on Thursday that it’s ready to ship doses “immediately upon recommendation by CDC.”
