(Reuters) - Novavax Inc said on Thursday its COVID-19 vaccine showed 80% efficacy in a trial in adolescents aged 12 to 17 years.

The results were obtained during the time the Delta variant was dominant in the United States, Novavax said, adding that the vaccine was 82% effective against disease with that strain.

The company started testing its vaccine in adolescents last year and late last month filed for authorization of the shot in U.S. adults, a much-awaited step following several delays.

Results from the company's trial in adults, which enrolled about 30,000 participants in the United States and Mexico, had shown vaccine efficacy of 90.4%, Novavax said in its press release.

Novavax expects to submit applications for clearance of its vaccine in those aged 12 to 17 to global authorities during the first quarter of 2022.
