Additional information
y Consult relevant ACIP statements for detailed
recommendations at www.cdc.gov/vaccines/hcp/acip-recs/
index.html.
y For calculating intervals between doses, 4 weeks = 28 days.
Intervals of ≥4 months are determined by calendar months.
y Within a number range (e.g., 12–18), a dash (–) should
be read as “through.”
y 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 3-2, Recommended and minimum ages and
intervals between vaccine doses, in General Best Practice
Guidelines for Immunization at www.cdc.gov/vaccines/hcp/
acip-recs/general-recs/timing.html.
y Information on travel vaccination requirements and
recommendations is available at www.cdc.gov/travel/.
y For vaccination of persons with immunodeciencies, see
Table 8-1, Vaccination of persons with primary and secondary
immunodeciencies, in General Best Practice Guidelines for
Immunization at www.cdc.gov/vaccines/hcp/acip-recs/

y For information about vaccination in the setting of a
vaccine-preventable disease outbreak, contact your
state or local health department.
y The National Vaccine Injury Compensation Program (VICP)
is a no-fault alternative to the traditional legal system for
resolving vaccine injury claims. All vaccines included in the
child and adolescent vaccine schedule are covered by VICP
except dengue, PPSV23, and COVID-19 vaccines. COVID-19
vaccines that are authorized or approved by the FDA are
covered by the Countermeasures Injury Compensation
Program (CICP). For more information, see www.hrsa.gov/
vaccinecompensation or www.hrsa.gov/cicp.

(if anti-HBs < 10mlU/mL) is recommended for certain
populations, including:
- Infants born to HBsAg-positive mothers
- Persons who are predialysis or on maintenance dialysis

- For detailed revaccination recommendations, see www.cdc.
gov/vaccines/hcp/acip-recs/vacc-specic/hepb.html.

administered during a campaign).
- Doses of OPV administered on or after April 1, 2016,

1 dose Tdap, then Td or Tdap booster every 10 years
y Persons age 7–18 years not fully vaccinated
*
with DTaP:
1dose Tdap as part of the catch-up series (preferably the rst
dose); if additional doses are needed, use Td or Tdap.
y Tdap administered at age 7–10 years:
- Children age 7–9 years who receive Tdap should receive
the routine Tdap dose at age 11–12 years.
- Children age 10 years who receive Tdap do not need the
routine Tdap dose at age 11–12 years.
