What is the mother-to-child infection rate? After vaccination and gammaglobulin injection for blockade, the success rate of blockade was found to be about 90% or more for mothers with major triplets and close to 100% for mothers with minor triplets with negative DNA. Can I breastfeed? Although the viral content of breast milk is hundreds of times higher than that of blood, mothers with major triplets can breastfeed if they have been blocked (after the birth of the child with globulin and vaccine), and if the mother has normal liver function and is in good general condition. Which is better for blockage: normal birth or cesarean section? There is no difference between normal delivery and cesarean section in terms of whether the baby is infected with hepatitis B. Either way, the baby must be exposed to a large amount of maternal blood and the infection rate during the perinatal period is very high without standardized immunization. The hepatitis B virus is not a factor in determining the mode of delivery, which should be decided by the obstetrician according to the condition of the baby at the time of delivery.
