Perinatal Hepatitis B

happy mother and baby

Hepatitis B infection during pregnancy can pose a serious risk to an infant. Infants who acquire hepatitis B virus (HBV) around the time of birth have approximately a 90% risk of developing chronic HBV infection. Chronic hepatitis B can lead to serious health complications later in life, including cirrhosis and hepatocellular carcinoma (liver cancer).

Preventing mother-to-child transmission of HBV is an important component of hepatitis B elimination efforts. Infants born to mothers who test positive for hepatitis B surface antigen (HBsAg) should receive post-exposure prophylaxis with hepatitis B immune globulin (HBIG) and hepatitis B vaccine within 12 hours of birth. Infants should then complete the recommended hepatitis B vaccine series and receive post-vaccination serologic testing (PVST) at 9–12 months of age, or 1–2 months after completion of the vaccine series if the series is delayed.

National recommendations for preventing perinatal hepatitis B transmission include:

  • Screening all pregnant women for HBsAg during each pregnancy, regardless of previous testing or vaccination status.
  • Testing all HBsAg-positive pregnant women for HBV DNA to help guide the use of maternal antiviral therapy during pregnancy. Maternal antiviral therapy is recommended for consideration when the HBV DNA level is ≥200,000 IU/mL.
  • Providing case management and appropriate follow-up for HBsAg-positive pregnant women and their infants.
  • Providing post-exposure prophylaxis with hepatitis B vaccine and HBIG within 12 hours of birth to infants born to HBsAg-positive mothers.
  • Ensuring infants complete the recommended hepatitis B vaccine series.
  • Completing PVST at 9–12 months of age, or 1–2 months after the final vaccine dose if the series is delayed. PVST should include HBsAg and anti-HBs.
  • Providing hepatitis B vaccination to infants according to current immunization recommendations.

Through timely maternal screening, appropriate immunoprophylaxis, vaccination, testing, and case management, perinatal hepatitis B transmission can be prevented in most infants.

    The Georgia Perinatal Hepatitis B Prevention Program (PHBPP) works to prevent perinatal hepatitis B transmission through case management, immunization, and follow-up care for infants born to HBsAg-positive mothers. In 2022, the program achieved high vaccination completion rates and immunity levels among infants while continuing efforts to address challenges such as incomplete follow-up testing and ensure equitable care across all regions. PHBPP remains dedicated to protecting infants and reducing the burden of hepatitis B in Georgia.
