Pfizer's and Moderna's formulas have been the go-to on pharmacy shelves, but Novavax remains an important option.

With the approval of Moderna's updated COVID-19 vaccine, doctors are hoping the shots will be available soon and Albertans will opt to roll up their sleeves to get one.

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.
