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.

Health Canada said Thursday it has authorized Novavax's updated COVID-19 vaccine for those aged 12 years and up.

Health Canada authorized Novavax’s updated COVID-19 vaccine that protects against currently circulating variants of the virus on Thursday. The protein-based vaccine, called Nuvaxovid, targets the JN.1 subvariant of Omicron, replacing the previous version which targeted the XBB.1.5 Omicron subvariant, the agency said in an online update.
