[Prevention of hepatitis B].

R Vetencourt, M E Vetencourt

    G.E.N
    |January 1, 1989
    PubMed
    Summary

    Preventing hepatitis B virus (HBV) infection involves immunoprophylaxis, including safe and effective passive (immunoglobulins) and active (vaccines) methods. Vaccination strategies are tailored based on infection prevalence and individual risk factors.

    Area of Science:

    • Virology
    • Immunology
    • Public Health

    Context:

    • Hepatitis B virus (HBV) infection remains a significant global health concern.
    • Immunoprophylaxis offers a critical strategy for preventing HBV transmission.
    • Understanding risk factors and tailored vaccination approaches is essential for effective control.

    Purpose:

    • To review current strategies for hepatitis B virus infection prevention.
    • To emphasize the role of immunoprophylaxis, including passive and active immunization.
    • To discuss the safety, efficacy, and application of hepatitis B vaccines and immunoglobulins.

    Summary:

    • Immunoprophylaxis, encompassing passive (immunoglobulins) and active (plasmatic and recombinant vaccines) methods, is reviewed for hepatitis B virus (HBV) prevention.
    • Both passive and active immunoprophylaxis are demonstrated to be safe, highly effective, and possess few secondary effects.
    • Vaccine response is influenced by age and immunological status, with limited contraindications. Pre- and post-exposure vaccination protocols are recommended based on specific risk groups and exposure scenarios, particularly in Venezuela where HBV prevalence varies significantly.

    Impact:

    • Provides a comprehensive overview of hepatitis B prevention through immunoprophylaxis.
    • Highlights the safety and efficacy of vaccines and immunoglobulins for HBV control.
    • Informs public health policies and clinical practice regarding hepatitis B vaccination strategies in diverse populations.
