On December 9, 2022 the CDC expanded the use of Pfizer and Moderna’s updated (bivalent) COVID-19 vaccine for children as young as 6 months.

  • Pfizer: For children age 6 months to 5 years who get the Pfizer primary series, the updated bivalent vaccine will be used as the third dose in the series, rather than as a separate booster. Children and teens age 5 and up should get the updated booster at least 2 months after they finish their 2-dose primary series.
  • Moderna: Children and teens age 6 months and up should get the updated Moderna booster at least 2 months after they finish their 2-dose primary series.
