[VACCINATION AGAINST HEPATITIS B: WHAT'S UP?]

Area of Science:

• Public Health
• Immunology
• Vaccinology

Context:

• Hepatitis B vaccination safety concerns have been debunked by extensive research.
• French national vaccination strategy for Hepatitis B Virus (HBV) implemented since the 1990s.
• Current HBV epidemiology in France necessitates ongoing vaccination efforts.

Purpose:

• To evaluate the effectiveness and safety of the French HBV vaccination strategy.
• To assess vaccination coverage across different demographics.
• To identify areas for improvement in HBV prevention.

Summary:

• The HBV vaccine is safe and effective; historical concerns about demyelinating diseases are unfounded.
• French vaccination strategies, including newborn, catch-up, and high-risk populations, are generally suitable.
• Vaccination coverage is increasing in newborns but remains insufficient in children, adolescents, and high-risk groups.

Impact:

• Mandatory vaccination of healthcare workers has significantly reduced occupational HBV transmission.
• Persistent HBV circulation and transmission risks underscore the need for continued vaccination and proof of immunization.
• Tailored vaccination protocols are essential for individuals with comorbidities to ensure optimal immune response.
• Hepatitis B vaccination can prevent severe liver diseases and reduce the need for liver transplantation.
