Question
If no antibody response occurs after receiving the Hepatitis B vaccine, do you need to get a booster shot? How long does it usually take for this treatment to take effect? Are there other effective treatment methods?
Answer
The sign of successful immunization is the conversion of the Hepatitis B surface antibody to a positive result, which provides protection for typically over two years. If neither parent of a newborn has been infected with Hepatitis B, the newborn should receive a genetic engineering Hepatitis B vaccine intramuscular injection in the deltoid muscle of the upper arm within 8 hours after birth (the same for children and adults). The recipient should regularly check the Hepatitis B three-system, and as long as the surface antibody remains present, it indicates that the immune ability is still intact. If no antibody response occurs after vaccination, consult a doctor about whether a booster shot or other treatment options are needed.
