Patient's question:
Does the hepatitis B vaccine need to be boosted if there is no antibody? How long does the treatment take to recover? Please help me! Is there any good method?Doctor's answer:
The sign of successful immunity is the conversion of hepatitis B surface antibody to positive, providing protection for a long time. (If both parents of a newborn do not have hepatitis B, the newborn should be given a dose of recombinant hepatitis B vaccine as soon as possible (within 8 hours) after birth, with intramuscular injection at the deltoid muscle of the upper arm (the same for children and adults). The protection period is generally more than 2 years, and the vaccinated person can regularly review the hepatitis B triad. As long as the surface antibody still exists, it proves that the immune ability remains.
