Moderna said on Tuesday that its coronavirus vaccine, authorized only for use in adults, was powerfully effective in 12- to 17-year-olds. In a clinical trial of the vaccine in adolescents, there were no cases of symptomatic Covid-19 among fully vaccinated teens, the company reported in a news release.
Moderna plans to apply to the Food and Drug Administration in June for authorization to use the vaccine in adolescents. If approved, its vaccine would become the second Covid-19 vaccine available to U.S. adolescents, after federal regulators authorized the Pfizer-BioNTech vaccine for 12- to 15-year-olds earlier this month.
