Hepatitis B Vaccination Schedule Recommendations

Introduction to Vaccination Schedules

The Centers for Disease Control and Prevention recommends that all infants receive their first dose of hepatitis B vaccine within 12 hours of birth, before hospital discharge, with subsequent doses at 1-2 months and 6 months of age 1, 4
For infants born to HBsAg-negative mothers, the recommended schedule is: first dose at birth, second dose at 1-2 months, and third dose at 6 months of age 1, 4
The American Academy of Pediatrics and the Centers for Disease Control and Prevention recommend that infants born to HBsAg-positive mothers receive the first dose of hepatitis B vaccine within 12 hours of birth, along with HBIG, with subsequent doses at 1-2 months and 6 months of age 1, 2

Children and adolescents who were not vaccinated as infants should follow a schedule of either 3 doses at 0, 1, and 6 months or an alternative 2-dose schedule of adult formulation at 0 and 4-6 months, as recommended by the Centers for Disease Control and Prevention 3, 6
Adults aged ≥18 years can follow a standard schedule of 3 doses at 0, 1, and 6 months, with options for alternative schedules, according to the Centers for Disease Control and Prevention 3

Hemodialysis patients and other immunocompromised adults should receive higher doses of the vaccine (40 μg) at 0, 1, and 6 months, with annual anti-HBs testing and booster doses when levels fall below 10 mIU/mL, as recommended by the Centers for Disease Control and Prevention 7, 8
The minimum interval between the first and second doses is 4 weeks, between the second and third doses is 8 weeks, and between the first and third doses is 16 weeks, according to the Centers for Disease Control and Prevention 8
Post-vaccination serologic testing is recommended for infants born to HBsAg-positive mothers, healthcare personnel, hemodialysis patients, HIV-infected persons, and other immunocompromised persons, with testing performed 1-2 months after completing the vaccination series, as recommended by the Centers for Disease Control and Prevention 2, 7, 8

An anti-HBs level ≥10 mIU/mL indicates adequate protection, according to the Centers for Disease Control and Prevention 1, 7
Delaying the birth dose beyond 12 hours for infants born to HBsAg-positive mothers significantly increases the risk of infection, as reported by the Centers for Disease Control and Prevention 1, 2
