COVID-19 Vaccine for Children and Teens

  • Adolescents ages 12 years and older receive the same dosage of Pfizer-BioNTech COVID-19 vaccine as adults.
    • The Pfizer-BioNTech vaccine for children ages 5 through 11 years has the same active ingredients as the vaccine given to adults and adolescents. However, children ages 5 through 11 years cannot get the Pfizer-BioNTech COVID-19 vaccine given to adults and adolescents. 
    • Children 5 through 11 years old will receive a separate vaccine formulation denoted in vials with orange caps of the Pfizer-BioNTech COVID-19 vaccine that has one-third the dose given to adolescents and adults. Vaccine vials for adults are denoted with purple caps. View formulation table (PDF).
  • In addition to receiving an age-appropriate dose that is one-third of the adult dose of Pfizer-BioNTech COVID-19 vaccine, children 5 through 11 years also receive the vaccine through smaller needles, designed specifically for children.
  • Unlike many medications, COVID-19 vaccine dosage does not vary by patient weight but by age on the day of vaccination.
