  1. Recommended Postexposure Prophylaxis for Percutaneous Exposure to Hepatitis B Virus* Vaccination and antibody status of exposed person Treatment when source is HBsAg† positive HBsAg negative Not tested or infection status unknown Unvaccinated HBIG‡X 1; Initiate hepatitis B series Initiate hepatitis B series Initiate hepatitis B vaccine series Known Responder§ No treatment No treatment No treatment Known non-responder, no revaccination HBIG X 1 and initiate revaccination No treatment; consider revaccination for future protection If known high-risk source, treat as if source were HBsAg positive. National Clinicians’ Post-exposure Prophylaxis Hotline (PEPline): 1.888.448.4911 Known non-responder to initial & revaccination series HBIG X 2 – second dose one month after the first No treatment If known high-risk source, treat as if source were HBsAg positive Previously Vaccinated Antibody response unknown Test exposed person for anti-HBs|| • If adequate¶, no treatment • If inadequate¶, HBIG X 1 and vaccine booster dose# No testing, no treatment Test exposed person for anti-HBs|| • If adequate¶, no treatment • If inadequate¶, vaccine booster dose# * Postexposure recommendations apply ≤7 days after exposure. † Hepatitis B surface antigen ‡ Hepatitis B immune globulin (0.06 mL/kg administered intramuscularly) § Person with anti-HBs antibody level of 10 mIU/mL || Antibody to hepatitis B surface antigen ¶ Adequate response is anti-HBs 10mIU/mL; inadequate response is anti-HBs<10mIU/mL #The person should be evaluated for antibody response after the vaccine booster dose. For persons who received HBIG, anti-HBs testing should be done when passively acquired antibody from HBIG is no longer detectable (eg, 4-6 mo); if they did not receive HBIG, anti-HBs testing should be done 1-2 months after the vaccine booster dose. If anti-HBs is inadequate (<10mIU/mL) after the vaccine booster dose, 2 additional doses should be administered to complete a 3-dose reimmunization series.
