Hepatitis B HVP immune globulin is best administered during the second trimester of pregnancy 789, and the first Hepatitis B HVP immune globulin and 30 micrograms of Hepatitis B vaccine is given to the child within 24 hours of birth, followed by Hepatitis B HVP immune globulin in the 23rd month and 30 micrograms of Hepatitis B vaccine in the 26th month, which generally prevents transmission to the child to the greatest extent possible. Breastfeeding does not increase the prevalence of hepatitis B virus infection in infants. On the contrary, when hepatitis B vaccine or hepatitis B vaccine combined with hepatitis B immune globulin is given at birth, the positive rate of hepatitis B surface antibody can reach 80 to 90, which is useful for infants. Because breast milk contains many nutrients and antiviral substances, the incidence and severity of common diseases in breastfed infants are significantly lower than in artificially fed children, so breastfeeding should be encouraged for mothers with hepatitis B. The key to reducing hepatitis B virus from mother to child is to vaccinate infants against hepatitis B as early as possible after birth, and even better if combined with hepatitis B immunoglobulin. All infants should be exclusively breastfed for at least the first four months and, if possible, the first six months, and continue breastfeeding until two years of age or older, based on the introduction of adequate complementary foods after six months. Non-breastfed infants are at higher risk of morbidity and mortality. Even in the absence of immunization measures, there is still no indication that breastfeeding by an infected mother increases the chance of infection in the infant. Thus, breastfeeding is the recommended infant feeding method even in high prevalence areas and without anti-immunization measures. If the mother has only hepatitis B antigen in her body and no antibodies, the child should be given a shot of high potency immunoglobulin after birth and a vaccine at the same time. After the child is vaccinated, usually after 3 months, the appropriate antibodies can occur, so that the child can be protected from infection, so that the hepatitis B mother can breastfeed. Six-month-old infant supplement added to the newborn of a hepatitis B surface antigen-positive mother should be injected with hepatitis B immunoglobulin as early as possible within 24 hours after birth, along with 10 μg of hepatitis B vaccine at different sites, which can significantly improve the effect of blocking mother-to-child, and the second and third doses of hepatitis B vaccine at intervals of 1 and 6 months, respectively. It is best not to breastfeed to avoid transmission to the baby.
