Question
What Causes a Negative Reaction to BCG Vaccine?
Answer
A negative reaction to the BCG vaccine indicates that the child is not sensitive to it and it does not provide preventive protection, so a booster shot is needed. How are your liver function and hepatitis B virus test results? If your baby’s BCG vaccination has failed, it is necessary to administer a booster shot as soon as possible. Regarding the hepatitis B prevention issue, you have used the hepatitis B immune globulin appropriately, and it is best to get a hepatitis B vaccine with a dose of 10 micrograms for better effectiveness. I think you should not continue breastfeeding as hepatitis surface antigen+ is contagious.
