The latest guidelines do not recommend hepatitis B immunoglobulin during pregnancy for pregnant women with HBV. Hepatitis B is contagious and can be transmitted vertically from mother to child, but the current guidelines no longer recommend hepatitis B immunoglobulin during pregnancy. If a patient with hepatitis B has a viral load greater than five-tenths of a power during pregnancy, such a patient may be considered for antiviral treatment starting at 26 weeks of gestation, which can be administered with tenofovir. In addition, all newborns born to pregnant women with hepatitis B should be immunized with hepatitis B vaccine and hepatitis B immunoglobulin immediately after birth, with a booster shot of hepatitis B vaccine at a later date. This type of interruption is generally recommended. Pregnant women with hepatitis B are advised to go to a specialized infectious disease unit or obstetrics and gynecology department for a doctor-advised interruption program.
