Information on travel vaccination requirements and recommendations is available at.

For further details, see Table 3-2, Recommended and minimum ages and intervals between vaccine doses, in General Best Practice Guidelines for Immunization. The repeat dose should be spaced after the invalid dose by the recommended minimum interval. 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.

Vaccine doses administered ≤4 days before the minimum age or interval are considered valid.

Within a number range (e.g., 12–18), a dash (–) should be read as “through.”.

Intervals of ≥4 months are determined by calendar months.

For calculating intervals between doses, 4 weeks = 28 days.

Consult relevant ACIP statements for detailed recommendations.
