How to prevent an unborn child from being infected with hepatitis B

Patient's question:

No

Doctor's answer:

Hepatitis B pregnant women should receive one high-titer hepatitis B immune globulin (100~200 international units) in the 7th, 8th, and 9th months of pregnancy to prevent intrauterine transmission of the hepatitis B virus. Children born to hepatitis B patients require special attention: newborns should be given high-titer hepatitis B immune globulin within 24 hours of birth, followed by hepatitis B vaccinations at 2, 3, and 5 months, which can effectively prevent hepatitis B infection.
Once the baby produces protective antibodies, they can avoid everyday contact infections, but it is important to avoid contact with broken mucous membranes or blood; additionally, avoid feeding the baby mouth-to-mouth.
