The 2023 Adult Immunization Schedule, which includes the COVID-19 vaccine for the first time, was published in the Annals of Internal Medicine. Neil Murthy, MD, MPH, and colleagues authored the 2023 Advisory Committee on Immunization Practices (ACIP) Recommended Adult Immunization Schedule for US individuals aged 19 and older. Changes to the 2023 schedule include a new section relating to the COVID-19 vaccine, which describes primary series recommendations for the general population followed by descriptions for moderately or severely immunocompromised individuals. Vaccine recommendations for Haemophilus influenzae type b, hepatitis A, and human papillomavirus remain unchanged. A newly licensed vaccine for hepatitis B was added to the description of the three-dose series. Hepatitis B vaccination is still recommended for all adults aged 19-59. For the 2022-2023 influenza season, routine annual vaccination is recommended. Any one of the quadrivalent high-dose inactivated
influenza vaccine, quadrivalent recombinant influenza vaccine, or quadrivalent adjuvanted inactivated influenza vaccine is preferred for adults aged 65 or older. A new polio vaccination addresses recommendations for adults at increased risk for poliovirus exposure.
