Unlike standard IVIG, which contains a broad mix of antibodies, Hyperimmune Globulins are prepared from donors who have high titers of a specific antibody. This is often achieved by vaccinating donors against a particular disease before they donate plasma.

Examples of these specialized derivatives include:

• Hepatitis B Immune Globulin (HBIG): Used for post-exposure prophylaxis (e.g., after a needle-stick injury) and to prevent infection in newborns of infected mothers.

• Rabies Immune Globulin (RIG): Administered immediately after a bite from a potentially rabid animal to neutralize the virus before it reaches the nervous system.

• Tetanus Immune Globulin (TIG): Used to treat active tetanus infections and for prophylaxis in patients with "tetanus-prone" wounds.

• Anti-D (Rh) Immunoglobulin: Given to Rh-negative mothers to prevent Hemolytic Disease of the Newborn in future pregnancies.
