Were the vaccines tested in children?


The Pfizer-BioNTech vaccine was authorized for use in children ages 12-15 after the manufacturer reported that tests in that age group showed it to be 100 percent effective at preventing symptomatic disease. Pfizer-BioNTech is now testing it in children ages 5-11, and Moderna is testing its vaccine in two different age groups: children under 12 (including babies as young as 6 months), and children ages 12-17. The FDA has not yet authorized the vaccines for use in those age groups.
