Effective hepatitis B vaccines are crucial for preventing chronic liver disease and cancer. This review covers HBV infection, immune responses, and the latest vaccine developments for global health.
Area of Science:
- Hepatology
- Immunology
- Vaccinology
Background:
- Hepatitis B virus (HBV) infection leads to chronic liver disease and hepatocellular carcinoma.
- Safe and effective HBV vaccines are available, achieving high global coverage.
- Monitoring and surveillance data inform vaccination policies, including booster doses.
Purpose of the Study:
- To provide an overview of HBV infection natural history.
- To summarize current and emerging HBV vaccine types, uses, and preclinical/post-field data.
- To discuss immune responses and the future of HBV infection control.
Main Methods:
- Literature review of HBV infection and vaccination.
- Analysis of surveillance and monitoring data for vaccination programs.
- Synthesis of information on preclinical and post-field vaccine studies.
Main Results:
- Universal HBV vaccination coverage is nearly complete globally.
- Accumulated data support the evaluation of booster vaccination policies.
- Updated information on various HBV vaccine sources, types, and applications is available.
Conclusions:
- HBV vaccination remains a cornerstone of global public health strategy.
- Continued research and surveillance are essential for optimizing HBV prevention.
- Understanding immune responses is key to developing future HBV infection control measures.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
