On May 10, 2021, the U.S. FDA authorized the Pfizer pediatric vaccine for children 12 to 15 years old under an Emergency Use Authorization (EUA), meaning the vaccine was proven safe and effective for this age group. The vaccine has since received full FDA approval. This vaccine is a two-dose series, and the doses should be administered three to eight weeks apart. An 8-week interval between the first and second doses may be best for some people age 12 and older, especially for males ages 12 to 39. Learn more here or talk with your healthcare provider. . Information about dosage and efficacy can be found in the vaccine’s U.S. FDA fact sheet.
