The COVID-19 vaccines for children have the same active ingredients as the primary vaccines given to adults. However, children receive a smaller, age-appropriate dose that is the right size for them. The smaller doses were rigorously tested and found to create the needed immune response for each age group. Your child should get the vaccine made for their age group.
Pfizer-BioNTech and Moderna have each created an updated booster that targets Omicron variants; however, the updated booster is only authorized for people age 12 and older. Learn more about the Pfizer and Moderna vaccines.
