US regulators approved Moderna Inc.’s COVID-19 vaccine for children, but for a narrower group than before, continuing Robert F. Kennedy Jr.’s controversial policy that restricts access to the shots for some kids.

Pfizer's COVID vaccine (Comirnaty) is fully approved for patients ages 12 and up, and authorized for kids ages 6 months through 11 years. Novavax's COVID shot (Nuvaxovid) is fully approved for people ages 65 and up, as well as those ages 12 to 64 with at least one health condition that puts them at risk for severe disease.

The U.S. Food and Drug Administration has granted full approval for Moderna's COVID-19 vaccine, Spikevax, in children aged 6 months through 11 years who are at an increased risk of the disease, the company said on Thursday.
