Hepatitis B vaccine 10 micrograms (at birth, 1 month, 6 months). Hepatitis B vaccine and hepatitis B immunoglobulin are administered at birth to the quadriceps (the muscle in front of the thigh) on each side, preferably not at the deltoid muscle. (Because BCG vaccination is given at the deltoid muscle). Breastfeeding in HBVDNA-positive patients increases the risk of mother-to-child transmission, and it is up to the patient to decide whether to breastfeed. Vaginal delivery of a newborn after regular vaccination does not increase the chance of infection in HBVDNA-positive patients. At 7 months of age, the child can be checked for hepatitis B test to see if the blockade is successful.
