After Emergency Use Authorization of Pfizer-BioNTech COVID-19 vaccine by the Food and Drug Administration (FDA), ACIP issued an interim recommendation for use of Pfizer-BioNTech COVID-19 vaccine in persons aged ≥16 years at its December 12, 2020, meeting (1). In addition, ACIP approved an amendment to include COVID-19 vaccine recommendations in the child and adolescent immunization schedule. After Emergency Use Authorization of Moderna COVID-19 vaccine by FDA, ACIP issued an interim recommendation for use of Moderna COVID-19 vaccine in persons aged ≥18 years at its December 19, 2020, emergency meeting (2). ACIP's recommendations on use of each vaccine are developed after in-depth reviews of vaccine-related data, including the epidemiology and societal impacts, vaccine efficacy and effectiveness, vaccine safety, quality of evidence, feasibility of program implementation, and economic analyses of immunization policy (3). The child and adolescent immunization schedule is published annually to consolidate and summarize updates to ACIP recommendations on vaccination of children and adolescents, and to assist health care providers in implementing current ACIP recommendations. The use of vaccine trade names in this report and in the child and adolescent immunization schedule is for identification purposes only and does not imply specific product endorsement by ACIP or CDC. For further guidance on the use of each vaccine, including contraindications and precautions, and any updates that might occur between annual updates to the child and adolescent immunization schedule, health care providers are referred to the respective ACIP vaccine recommendations at https://www.cdc.gov/vaccines/hcp/acip-recs. § Printable versions of the 2021 child and adolescent immunization schedule and ordering instructions are available at https://www.cdc.gov/ vaccines/schedules/hcp/imz/child-adolescent.html. Vaccine-specific changes in the 2021 child and adolescent immunization schedule for children and adolescents aged 18 years or younger include new or updated ACIP recommendations for influenza vaccine (4) meningococcal serogroups A, C, W, and Y (MenACWY) vaccines (5), and COVID-19 vaccines (1, 2) .
