After accidental exposure to the blood and body fluids of an HBV-infected person, treatment can be done as follows: 1. Serological testing: HBV DNA, hepatitis B five and liver function should be tested immediately and retested within 3 and 6 months.
2. Active and passive immunization: If you have been vaccinated against hepatitis B and have known anti-HBs ≥10 mIU/mL, it means that you have protective antibodies and may not be treated specially. If you have not received hepatitis B vaccine, or have received hepatitis B vaccine but anti-HBs <10 mIU/mL or the level of anti-HBs is unknown, you should immediately inject HBIG 200-400 IU (passive immunization) and receive one dose of hepatitis B vaccine (20 mg) at different sites at the same time, and receive the second and third doses of hepatitis B vaccine (20 mg each) 1 and 6 months later, respectively (active immunization).
