After exposure to hepatitis B virus (HBV), appropriate and timely prophylaxis can prevent HBV infection and subsequent development of chronic infection or liver disease. The mainstay of postexposure prophylaxis (PEP) is hepatitis B vaccine, but, in certain circumstances, hepatitis B immune globulin is recommended in addition to vaccine for added protection. This page provides links to PEP guidelines and resources by type of exposure.

Postexposure Prophylaxis to Prevent Hepatitis B Virus Infection

Postexposure Prophylaxis section provides recommendations for management of persons who are exposed to HBV through a distinct, identifiable exposure to blood or body fluids that contain blood, in occupational and nonoccupational settings.
Infants born to HBV-infected mothers should receive hepatitis B vaccine and hepatitis B immune globulin within 12 hours of birth. See the Perinatal Transmission page for complete guidelines on postexposure prophylaxis for newborns.
