Pfizer says vaccine safe and effective for adolescents

Pfizer announced that its vaccine against Covid-19 is safe and “100% effective” for people as young as 12. The pharmaceutical company recently finished trials in 12-15 year-olds and will be presenting its findings soon to the U.S. Food and Drug Administration, to ask for the vaccine to be approved for use in adolescents.

The trial included 2,260 trial participants. During the trial, 18 people in the control group, who did not receive a vaccine, developed Covid-19. None of the people who got a vaccine developed the disease.
