Question

A carrier of the hepatitis B virus (HBV) with a hepatitis B surface antigen (HBsAg) titer of 1.0, inquires about the timing and dosage of hepatitis B immunoglobulin (HBIG) and vaccine injections and their relationship to the effectiveness of mother-infant intervention.

Answer

Based on the description, the use of hepatitis B vaccine may not have followed the standard schedule. It is recommended to perform an antibody test for hepatitis B. If no antibodies are detected, vaccination should be administered promptly. There is no strict requirement for the injection site, so there is no need to worry excessively.
