The U.S. Food and Drug Administration (FDA) has authorized a single booster dose of the Pfizer-BioNTech COVID-19 vaccine bivalent for children six months old through four years of age.
At least two months prior to getting this booster, children must have completed their three-dose primary vaccination series.
Children in that age range who only received the first two doses of the Pfizer COVID-19 vaccine are not currently eligible for this booster. The FDA recommends that they complete the three-dose series.
