The Pfizer-BioNTech vaccine proved 93% effective at keeping adolescents 12 to 18 out of the hospital, according to an analysis by the Centers for Disease Control and Prevention published Tuesday. The report may help boost uptake of the vaccine among children ages 5-11 once it's authorized, likely in the coming weeks. "Findings reinforce the importance of vaccination to protect U.S. youths against severe COVID-19,'' the authors wrote. The Pfizer vaccine is the only one currently authorized for adolescents in the U.S. Moderna has requested authorization of its vaccine but has yet to receive it. Johnson & Johnson is testing its inoculation on teens.
