Pfizer on recently requested to expand use of its Covid-19 vaccine to adolescents ages 12 to 15.
The request asks the Food and Drug Administration to amend the emergency use authorization, which the FDA originally granted late last year for people ages 16 and up.
Last week, Pfizer-BioNTech said its Phase 3 clinical trials showed its vaccine was safe and 100 percent effective in 12- to 15-year-olds, though the findings have not been peer-reviewed.
“The hope of starting to vaccinate this age group before the start of the next school year,” CEO Albert Bourla said in a statement when those results were released.
