Perinatal Hepatitis B Prevention: Transmission
  • Screen all women early in pregnancy for HBsAg. If the woman's lifestyle or clinical symptoms are suspicious of acute hepatitis, additional HBsAg serology should be performed later in the pregnancy.
  • Report all HBsAg-positive women to your local health department, even if you think they have been reported before.
  • Document the results of the HBsAg serology in the patient's prenatal record, hospital chart, and in the patient's immunization record card.¬†The Oregon Public Health Division¬† Immunization Program can provide cards to be used for this purpose at no charge.
  • Provide educational materials to women determined to be HBsAg-positive.
    Materials are available from the Centers for Disease Control and Prevention (CDC)

  • Post-vaccination serology should be completed 3 to 9 months after the final dose of vaccine. Document in the patient's chart and personal immunization record.
  • Susceptible household members and other close contacts should also be vaccinated. State-supplied vaccine is available for these clients.
  • Educate HBsAg-positive women.
