Novavax says it will apply for an FDA emergency use authorization for its Covid-19 vaccine this month, extending slightly the 12/31/21 deadline it previously announced. Reuters [reports](https://www.reuters.com/business/healthcare-pharmaceuticals/novavax-submits-data-us-fda-covid-19-vaccine-2021-12-31/?ref=fdaweb.com) the company has delayed its U.S. submission multiple times due to development and manufacturing issues.

The company released data 6/2021 showing its vaccine was more than 90% effective against several coronavirus variants, including delta. The company has said the vaccine also is effective against omicron, but it also is working to develop a vaccine specifically tailored for omicron, with clinical studies expected to start in the first quarter of this year.

The Novavax two-dose protein-based vaccine has already been authorized by the European Union, the World Health Organization, India, Indonesia, and the Philippines, and is pending approval in Japan.
