The Food and Drug Administration has issued a long-awaited approval of Novavax’s COVID-19 vaccine but with unusual restrictions. Novavax makes the nation’s only traditional protein-based coronavirus vaccine – and until now it had emergency authorization from FDA for use in anyone 12 and older.

After a six-week delay, the US Food and Drug Administration has approved Novavax’s Covid-19 vaccine, according to a letter from the agency, but only for people 65 and older and those 12 and up who have at least one underlying condition that puts them at higher risk of severe illness.

After a six-week long delay, The Food and Drug Administration (FDA) has finally approved a more traditional protein-based covid vaccine produced by pharmaceutical giant Novavax.
