Children as young as 6 months can now receive an updated Covid-19 vaccine

PHILADELPHIA -- Children as young as 6 months are now eligible to receive an updated Covid-19 vaccine.

The US Food and Drug Administration on Thursday authorized updated Covid-19 vaccines from Moderna and Pfizer/BioNTech for use in children from ages 6 months through 5 years.

The bivalent vaccines target the original strain as well as the BA.4/5 Omicron strains. Bivalent vaccines were previously authorized as a booster for people age 5 and older.

"More children now have the opportunity to update their protection against COVID-19 with a bivalent COVID-19 vaccine, and we encourage parents and caregivers of those eligible to consider doing so -- especially as we head into the holidays and winter months where more time will be spent indoors," FDA Commissioner Dr. Robert Califf said in a statement.

Not all young children are eligible to receive an updated vaccine:

"Children in this age group who already completed their primary series would still be expected to have protection against the most serious outcomes from the currently circulating omicron variant. The data to support giving an updated bivalent booster dose for these children are expected in January. The agency is committed to evaluating those data as quickly as possible," the FDA said in its announcement.

In general, Covid-19 vaccinations have been slow among young children. According to data from the US Centers for Disease Control and Prevention, less than 5% of children younger than 5 are fully vaccinated against the coronavirus, having completed their primary series of vaccinations. Among people ages 5 and older, 73% are vaccinated, and 13% are vaccinated and boosted.

The FDA authorization comes as the United States is experiencing high levels of respiratory viruses, including flu and RSV, and rising Covid-19 hospitalizations.
