Administer recommended vaccines if immunization history is incomplete or unknown. Do not restart or add doses to vaccine series for extended intervals between doses. When a vaccine is not administered at the recommended age, administer at a subsequent visit. The use of trade names is for identification purposes only and does not imply endorsement by the ACIP or CDC.

Additional information

COVID-19 Vaccination

ACIP recommends use of COVID-19 vaccines for everyone ages 5 and older within the scope of the Emergency Use Authorization or Biologics License Application for the particular vaccine. COVID-19 vaccine and other vaccines may be administered on the same day. See the COVID-19 Vaccine Product Information page for additional information about COVID-19 vaccines authorized for use in the United States.

• Consult relevant ACIP statements for detailed recommendations.
• For information on contraindications and precautions for the use of a vaccine, consult the General Best Practice Guidelines for Immunization and relevant ACIP statements.
• For calculating intervals between doses, 4 weeks = 28 days. Intervals of ≥4 months are determined by calendar months.
• Within a number range (e.g., 12–18), a dash (–) should be read as "through."
• Vaccine doses administered ≤4 days before the minimum age or interval are considered valid. Doses of any vaccine administered ≥5 days earlier than the minimum age or minimum interval should not be counted as valid and should be repeated as age-appropriate. The repeat dose should be spaced after the invalid dose by the recommended minimum interval. For further details, see Table 3-1, Recommended and minimum ages and intervals between vaccine doses, in General Best Practice Guidelines for Immunization.
• Information on travel vaccination requirements and recommendations is available at https://www.cdc.gov/travel/.
• For vaccination of persons with immunodeficiencies, see Table 8-1, Vaccination of persons with primary and secondary immunodeficiencies, in General Best Practice Guidelines for Immunization, and Immunization in Special Clinical Circumstances (In: Kimberlin DW, Brady MT, Jackson MA, Long SS, eds. Red Book: 2018 report of the Committee on Infectious Diseases. 31st ed. Itasca, IL: American Academy of Pediatrics, 2018:67–111).
• For information about vaccination in the setting of a vaccine-preventable disease outbreak, contact your state or local health department.
• The National Vaccine Injury Compensation Program (VICP) is a no-fault alternative to the traditional legal system for resolving vaccine injury claims. All routine child and adolescent vaccines are covered by VICP except for pneumococcal polysaccharide vaccine (PPSV23). For more information, see www.hrsa.gov/vaccinecompensation/index.htmlexternal icon.

Special situations

• Wound management in persons age 7 years or older with history of 3 or more doses of tetanus-toxoid-containing vaccine: For clean and minor wounds, administer Tdap or Td if more than 10 years since last dose of tetanus-toxoid-containing vaccine; for all other wounds, administer Tdap or Td if more than 5 years since last dose of tetanus-toxoid-containing vaccine. Tdap is preferred for persons age 11 years or older who have not previously received Tdap or whose Tdap history is unknown. If a tetanus-toxoid-containing vaccine is indicated for a pregnant adolescent, use Tdap. For detailed information, see https://www.cdc.gov/mmwr/volumes/69/wr/mm6903a5.htm.
