Patient's question:
Doctor, hello! I am an HBV carrier with, and my DHA virus test was negative. During childbirth, my child received an injection of hepatitis B immune globulin (100 units) in the right arm and buttocks, and a hepatitis B vaccine in the same area within half an hour after birth. On the second day, my child received the BCG vaccine in the left arm. Later, due to pneumonia, the baby was in recovery, so on the 31st day, only an additional dose of hepatitis B immune globulin (100 units) was administered, but the second dose of hepatitis B vaccine (10 micrograms) was not given until two and a half months later. Could this affect the effectiveness of mother-to-child transmission prevention?Doctor's answer:
According to your description, your main issue is the use of the hepatitis B vaccine. Advice: Based on your specific situation, first, the use of the hepatitis B vaccine involves receiving one dose of hepatitis B immune globulin and one dose of the vaccine immediately after birth, followed by another dose of the vaccine one month later, and a third dose six months later. Alternatively, you can receive one dose of hepatitis B immune globulin at birth, followed by another dose of hepatitis B immune globulin one month later, and receive the hepatitis B vaccine simultaneously. Subsequently, you should receive another dose of the vaccine one month later and a final dose six months later. Based on your description, it seems that the vaccine was not administered according to the recommended schedule, which may theoretically affect the production of hepatitis B antibodies. We recommend taking your child to the hospital for a hepatitis B antibody test to check if antibodies have formed. If not, vaccination should be administered promptly. Additionally, there are no strict requirements for the injection site, so you do not need to be too anxious.
