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 CDC Table
, Recommended and minimum ages and intervals between vaccine doses, in General Best Practice Guidelines for Immunization

For vaccination of persons with immunodeficiencies, see Table
, 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.

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). Learn More Here
