While the new mRNA vaccines from Moderna and Pfizer-BioNTech have dominated the COVID-19 vaccine story, there is another type of shot that uses a more traditional vaccine-making technology, used by Novavax.

On Aug. 22, the U.S. Food and Drug Administration announced the approval of a new Novavax COVID vaccine, as well as updated versions of the Pfizer-BioNTech and Moderna vaccines. According to NPR, this latest vaccine is already being distributed and administered across the country.

Doctors share when to get the new COVID-19 shot, its side effects, what variants it protects against, how soon to get a booster after infection, and more.
