2023 Vaccination Schedule: 0-18 Years of Age

  1. Hepatitis B (HepB) vaccine. (Min age: birth)
At birth:

• HBsAg-negative mother: administer 1 dose of monovalent HepB vaccine within 24hrs of birth for all medically stable infants ≥2000g. For infants <2000g, give 1 dose at chronological age 1 month or hospital discharge (whichever is earlier even if weight remains <2000g).

• HBsAg-positive mother: administer 1 dose of monovalent HepB vaccine and hepatitis B immune globulin (HBIG) within 12hrs of birth, regardless of birth weight. For infants <2000g, administer 3 more doses of vaccine (4 total) beginning at age 1 month. Test for HBsAg and antibody to HBsAg (anti-HBs) at age 9–12mos or 1–2mos after final dose if the series was delayed.

• Unknown HBsAg status: administer monovalent HepB vaccine within 12hrs of birth, regardless of birth weight. For infants <2000g, add HBIG within 12hrs of birth, and 3 more doses of vaccine (4 total) beginning at age 1 month. For infants weighing ≥2000g, determine mother’s HBsAg status as soon as possible and, if she is HBsAg-positive, also give HBIG as soon as possible but no later than age 1wk. If HBsAg-positive or status remains unknown, test for HBsAg and anti-HBs at age 9–12mos or 1–2mos after final dose if the series was delayed.

   Doses after the birth dose:

• The 2nd dose should be administered at age 1–2mos and the 3rd dose at 6–18mos. Monovalent HepB vaccine should be used for doses administered before age 6wks.

• Infants who did not receive a birth dose should receive 3 doses of a HepB-containing vaccine as soon as feasible.

• The minimum interval is 4wks for the 1st and 2nd dose, 8wks for the 2nd and 3rd dose, and 16wks for the 1st and 3rd dose (if 4 doses, substitute 4th dose for 3rd dose in these calculations). The final (3rd or 4th) dose in the HepB vaccine series should be administered no earlier than age 24wks.

• Administration of a total of 4 doses of HepB vaccine is permitted when a combination vaccine containing HepB is administered after the birth dose.

• Revaccination may be recommended for: infants born to HBsAg-positive mothers, hemodialysis patients, or other immunocompromised persons.

• For catch-up vaccination recommendations, refer to the 2023 Catch-Up Vaccination Schedule: 4 Months–18 years chart.

  2. Rotavirus (RV) vaccine. (Min age: 6wks for both RV1 [Rotarix] and RV5 [RotaTeq])

• Administer a series of RV vaccine to all infants as follows:

1. If Rotarix is used, administer a 2-dose series at 2 and 4mos of age.

2. If RotaTeq is used, administer a 3-dose series at ages 2, 4, and 6mos.

3. If any dose in the series is either RotaTeq or unknown, default to 3-dose series.

  3. Diphtheria, tetanus, and acellular pertussis (DTaP) vaccine. (Min age: 6wks. Exception: DTaP-IPV [Kinrix, Quadracel]: 4yrs)

If the 4th dose was inadvertently given as early as 12mos, it may be counted if given ≥4mos after the 3rd dose.

• 5th dose of DTaP vaccine is not needed if 4th dose was given at age ≥4yrs and ≥6mos after 3rd dose.

• For wound management in children age <7yrs with ≥3 doses of tetanus-toxoid-containing vaccine, administer DTaP for all wounds except clean and minor wounds if >5yrs since last dose of tetanus-toxoid-containing vaccine.
