Passive Immunization

Passive immunization is a medical practice that involves introducing antibodies or antigen-binding fragments (i.e., antibody fragments) into a patient in order to prevent or treat a particular illness. Passive immunization can be used to protect individuals against many different infectious diseases, including influenza, chickenpox, and measles. Additionally, passive immunization may be used to treat certain cases of food poisoning and poisoning due to toxins. This type of immunization is advantageous as it is fast-acting, and can be used to protect individuals with weakened immune systems, such as those with HIV/AIDS or cancer.
