    Hepatitis B immunoglobulin is still needed, but screening blood donors for immune plasma is inefficient. Active immunization with the hepatitis B vaccine offers a more effective strategy for plasma collection.

    Area of Science:

    • Immunology
    • Vaccinology
    • Transfusion Medicine

    Background:

    • Hepatitis B immunoglobulin (HBIG) is crucial for passive immunization, even with a safe hepatitis B vaccine.
    • Immune plasma is essential for producing HBIG, necessitating a reliable source of plasma from hepatitis B-recovered or immunized individuals.

    Purpose of the Study:

    • To evaluate the feasibility and efficiency of screening a large blood donor population for hepatitis B immune plasma.
    • To identify optimal strategies for obtaining plasma for immunoglobulin production.

    Main Methods:

    • Screening of a substantial number of blood donors to identify individuals with high levels of hepatitis B antibodies.
    • Logistical analysis of the donor screening program to assess its efficiency and resource requirements.

    Main Results:

    • The current program of screening blood donors for hepatitis B immune plasma was found to be inefficient and labor-intensive.
    • Identifying suitable plasma donors through mass screening presents significant logistical challenges.

    Conclusions:

    • Relying solely on screening existing blood donors is an inefficient method for obtaining hepatitis B immune plasma.
    • A proactive approach involving active immunization with the hepatitis B vaccine is a more effective strategy for securing plasma for immunoglobulin production.
