Recommended Childhood and Adolescent Immunization Schedule: United States, 2025

Publication Date: November 21, 2024
Last Updated: November 22, 2024

Key Updates for 2025

  • COVID-19:
    • The vaccine formula has been updated for 2024-’25. All individuals ages 6 month and older should receive at least one dose of the 2024-’25 vaccine and additional COVID vaccine doses are recommended for children and adolescents who are immunocompromised. Updated notes state all doses should be from the same manufacturer for healthy children ages 6 months through 4 years and immunocompromised children and adolescents receiving their initial vaccine series.
  • Dengue:
    • The schedule clarifies the vaccine is recommended only for certain populations in the age group.
  • Diphtheria, tetanus and acellular pertussis (DTaP):
    • A note addresses the use of Td vaccine in children under 7 years with a contraindication to the pertussis component of DTaP.
  • Haemophilus influenzae type b (Hib):
    • Vaxelis is one of two preferred vaccines to protect American Indian/Alaska Native infants from Hib. The other preferred vaccine is PedvaxHIB.
  • Inactivated poliovirus:
    • Clarifies an earlier recommendation that catch-up vaccination is recommended for 18-year-olds who are known or suspected to be unvaccinated or incompletely unvaccinated.
  • Influenza:
    • Vaccines for 2024-’25 are trivalent. High-dose inactivated and adjuvanted inactivated influenza vaccines are acceptable options for 18-year-old solid organ transplant recipients who are receiving immunosuppressive medications with no preference over other age-appropriate inactivated or recombinant influenza vaccines.
  • Measles, mumps, rubella:
    • A new note indicates children 12 months and older vaccinated with one dose should get a second dose at least four weeks after the first if they are going to travel internationally.
  • Measles, mumps, rubella, varicella:
    • The vaccine is contraindicated in HIV-infected people.
  • Meningococcal B:
    • Bexsero dosing has been changed to a two-dose series for healthy adolescents and a three-dose series for those at increased risk of disease. Patients who need rapid protection (such as during an outbreak) can choose a three-dose series.
  • Respiratory syncytial virus (RSV):
    • Updated notes clarify that for infants born in October through March, the ideal timing of nirsevimab administration is during the birth hospitalization. In addition, infants born to people who received an RSV vaccine during a previous pregnancy should receive nirsevimab.
