Moderna's Covid-19 vaccine is safe and highly effective in children ages 12 to 17, the company said Tuesday.
It would be the second Covid-19 vaccine available for the age group if it is authorized for use, in addition to the Pfizer-BioNTech vaccine.
The Moderna vaccine is given as two doses, four weeks apart. Moderna said its Phase 2/3 clinical trial included more than 3,700 participants, half of whom received the vaccine and half of whom received a placebo.
The company said there were four cases of Covid-19 among the placebo group starting two weeks after second doses were administered, compared with none in the vaccine group, meaning the vaccine was 100 percent effective.
When the company looked for milder cases of Covid-19 after just the first dose, the vaccine was shown to be 93 percent effective against any infection, not just symptomatic illness.
Moderna's vaccine was shown to be around 95 percent effective in clinical trials in preventing symptomatic illness in adults. Real-world data the CDC released in March found it to be about 90 percent effective.
