Adult Immunization Schedule Appendix

Recommendations for Ages 19 Years or Older, United States, 2025

Purpose

Guide health care providers in determining contraindications and precautions for each vaccine type.

How to use the schedule

Vaccines in the Adult Immunization Schedule

To make vaccination recommendations, healthcare providers should:

  1. Determine recommended vaccine by age (Table 1 - By Age)
  2. Assess need for additional recommended vaccinations by medical condition or other indication (Table 2 - By Medical Condition)
  3. Review vaccine types, dosing frequencies and intervals, and considerations for special situations (Notes)
  4. Review contraindications and precautions for vaccine types (Appendix)
  5. Review new or updated ACIP guidance (Addendum)
