What is Immune Globulin (IG) used for?

Immune Globulin (IG) is used primarily to provide passive immunity against specific infections. This is achieved by administering a concentration of antibodies from human plasma, which can be used to confer temporary immunity or protect individuals who are at high risk for infections due to various factors such as exposure to infectious agents or certain medical conditions. This passive immunity is particularly important in cases where the body may not have enough time to produce its own antibodies, such as following exposure to certain pathogens or in individuals who may not respond adequately to vaccination.

The other choices do not accurately reflect the primary purpose of Immune Globulin. For instance, IG is not used for enhancing vaccine storage or replacing missing vaccines, as vaccines and immune globulins serve different roles within immunization practices. Additionally, supporting healthy diets is unrelated to the function of IG, which focuses solely on providing immediate immune protection.
