Pfizer Vaccine Demonstrates 100% Efficacy in 12-15 Year Olds

March 31, 2021

Today, Pfizer-BioNTech published a press release announcing the results of their Phase 3 clinical trial in adolescents. The trial enrolled 2,260 participants in the United States, aged 12 to 15, with 1,129 participants in the placebo group and 1,131 participants in the vaccinated group. In the trial, 18 cases of COVID-19 infections were observed in the placebo group. Comparatively, none of the participants from the vaccinated group contracted COVID-19.

The vaccine is currently only authorized for people aged 16 and older in the United States, so this data may play a role in amending the vaccine’s emergency use authorization. It is important to note that while this data is still under review, this is promising news. The next steps include requesting expansion of the Emergency Use Authorization (EUA) by the FDA in the United States.
