The U.S. Food and Drug Administration (FDA) has authorized, and the Centers for Disease Control and Prevention (CDC) recommends the Pfizer-BioNTech and Moderna COVID-19 vaccines for children 6 months and older. The Moderna vaccine is for children ages 6 months to 5 years and is a two-dose primary series, while the Pfizer vaccine is for children ages 6 months to 4 years, and is a three-dose primary series. The CDC has additional information about doses. Possible vaccine side effects are the same as other pediatric vaccines and may include fever, tiredness, irritability and tenderness at the injection site.

Johns Hopkins Medicine will offer vaccines for these age groups starting on Friday, June 24 through our Maryland locations. Check this web page for updates on vaccine clinic hours and locations. Information will also be posted regarding availability of vaccine brand type (Moderna or Pfizer) by location.
