ABSTRACT
Hepatitis B virus (HBV) infection remains a serious global health problem, which can lead to acute and chronic liver diseases and a variety of complications. HBV vaccination, which induces B cells to secrete protective hepatitis B surface antibody (HBsAb), is an important measure to prevent HBV infection. Some studies have shown that different individuals have different responses to HBV vaccine, which can be divided into ultra-high/high, normal/medium and low/non-response. Research on the potential mechanisms can provide reference for the preparation of high-titer HBsAb and the prevention and treatment of HBV infection. This paper reviewed the research situation and progress in the characteristics and mechanism of B cells in different responders after HBV vaccination.
