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.

Moderna’s Covid vaccine for children has been given full FDA approval, making it the first such shot for kids in the U.S. that will no longer be administered under an emergency use authorization.

The new memos from the Food and Drug Administration show how the agency’s vaccine chief, Dr. Vinay Prasad, personally intervened to place restrictions on COVID shots from vaccine makers Novavax and Moderna. Both vaccines were approved by the FDA in May after months of analysis by rank-and-file FDA reviewers.
