I often meet friends who ask whether hepatitis B mothers can breastfeed and whether they will infect their children. In fact, there is nothing special about hepatitis B mothers, and after some medical measures, they are no different from ordinary mothers. The following is a summary of frequently asked questions and answers. 1, hepatitis B mothers can breastfeeding? The current medical consensus is that regardless of whether the mother is “major triple positive” or “minor triple positive”, as long as the newborn receives hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine within 12 hours of birth, it will have a high protection rate and the possibility of being infected with hepatitis B is very small, therefore breastfeeding is advocated. 2.How about the protection rate of combined immunization blockade? Combined immunization is the injection of hepatitis B immunoglobulin and hepatitis B vaccine to newborns at the same time, so that the protection rate of mother-to-child transmission interruption is as high as 93-97%, and there are examples of success everywhere. On the contrary, if the newborn is not co-immunized, 90% of the newborns delivered by hepatitis B surface antigen (HBsAg) positive mothers will eventually be infected with hepatitis B. 3. Can the mother-to-be protect her baby with HBIG? Some obstetricians and gynecologists in China have concluded that HBIG injections after 28 weeks of pregnancy can reduce the risk of mother-to-child transmission of hepatitis B virus (HBV). However, these studies have not been scientifically proven, and there are still some health risks associated with hepatitis B immunoglobulin injections for mothers. Therefore, the WHO and the Ministry of Health in China do not recommend this method to prevent mother-to-child transmission of HBV. 4. Will the baby still be infected after the co-immunization? About one month after the vaccination, parents should take their children to the hospital for a blood test to check the level of antibodies to the hepatitis B virus. If the antibody level is low, a booster vaccination will be needed. This test can be done between about 7 months and 1 year of age. 5. Can a cesarean section prevent mother-to-child transmission of hepatitis B? The risk of hepatitis B transmission is the same for infants born by cesarean section compared to normal delivery, as long as the newborn receives the standard combined immunization. Currently, most international obstetric guidelines do not recommend the use of cesarean delivery to prevent mother-to-child transmission of hepatitis B virus in the perinatal period. If you want to have a cesarean section, you should do it, and you don’t have to worry about transmission. 6. In which cases are babies more likely to be infected? It has been found that the main reason for failure is a high viral load (>108 copies/ml) in the mother’s body, which is professionally known as a high viral load. Therefore, if a patient with a high viral load is planning to get pregnant, it is recommended to discuss with your doctor and develop a well thought out treatment plan and wait until the time is right before getting pregnant.
