The submission is based on data from two key clinical trials in the United States and Mexico as well as in the UK that showed the vaccine was 90% effective against COVID-19.

Novavax's protein-based vaccine is being reviewed by the U.S. Food and Drug Administration and has received approvals from the European Union and the World Health Organization.

It has also been cleared for use in adults in countries including the UK, New Zealand and Australia. The company last week said its vaccine was about 80% effective in a late-stage trial in adolescents.
