Perinatal Hepatitis B Prevention Program

This program provides support, education, and reminders to providers to ensure that all infants born to HBsAG+ mothers follow the CDC protocol to prevent contracting hepatitis B during delivery.

All pregnant women should be tested for hepatitis B with every pregnancy.

Perinatal hepatitis B Prevention Program Guidelines (PDF) is available online to assist prenatal providers, pediatricians, parents, hospitals, and local health jurisdictions. 

Infant Protocol

These infants should receive HBIG and dose #1 of hepatitis B vaccine within 12 hours of birth.  They should receive dose #2 at 1-2 months, dose #3 at 6 months (not sooner than 24 weeks), and should have post-vaccine serology at 9-12 months (typically at the 12 month well child check).  This is an updated CDC protocol as of 10-9-2015.

Post vaccine serology is an HBsAG and an anti-HBs. If the HBsAg is negative and the anti-HBs is positive, the child is immune due to vaccination.  Infants that do not respond to the first series should receive a second 3-dose series and be tested 1-2 months after the final dose.  If they still show no protection, then they are termed a "non-responder" and are susceptible to hepatitis B infection.  Parents/guardians should be counseled about the child receiving HBIG if exposed to someone infected with hepatitis B. 

Fewer than 5% of person who receive 6 doses of properly administered hepatitis B vaccine fail to respond to the vaccine successfully.
