Moderna on Thursday filed for emergency use authorization from the Food and Drug Administration to use its COVID-19 vaccine in adolescents ages 12 to 17, NBC News reports.
If cleared by the FDA, it will become the second Covid-19 vaccine available in the United States for teens under 18 along with Pfizer-BioNTech's vaccine, which was authorized for adolescents ages 12 to 15 in May.
Moderna said in May that results from its clinical trial among children ages 12 to 17 showed its two-dose mRNA vaccine to be safe and highly effective. The trial included more than 3,700 participants.
