摘要

Infection with hepatitis B virus (HBV) is one of the significant challenges worldwide. Despite the availability of antiviral drugs against this virus, the most critical strategy to prevent HBV infection is HB vaccination. Basically, despite widespread conventional HB vaccination, due to various reasons, including waning of hepatitis B surface antibody (HBsAb) titer after vaccination, the emergence of vaccine-escape mutants, failure to respond to the vaccine due to viral and host factors, levels of response in high-risk individuals and non-responders to conventional HB vaccination remains a major, unsolved and severe concern. This review focuses on the underlying reasons for conventional hepatitis B vaccination failures. It also suggests solutions to overcome these failures by highlighting significant advances in vaccination, including hepatitis B third-generation vaccines and adjuvanted hepatitis B vaccines as efficient alternatives to second-generation vaccines. Potentially, these new strategies will compensate for the shortcomings caused by second-generation vaccines. Adherence to these denouements has a significant role in preventing the circulation of HBV among individuals and reducing the global burden of HBV-related diseases.
