It means that you have been vaccinated with hepatitis B vaccine or infected with hepatitis B virus, but you have recovered, that is, the body has produced protective hepatitis B antibodies (surface antibodies) through its own immune system, which not only completely eliminated hepatitis B virus, but also won't be attacked by hepatitis B virus in the future, and it is no longer contagious and does not need treatment. ?
In fact, many people are infected with hepatitis B virus invisibly. Some people are infected with hepatitis B virus, and because of their strong immunity, they have eliminated hepatitis B virus without symptoms.
Positive core antibody means that there is hepatitis B virus infection, which may exist for a long time, so leave it alone and do not need treatment, because its existence has no effect on the body.
