Passive Immunization

Passive immunization is a form of medical procedure in which antibodies are administered to an individual in order to provide protection against diseases such as measles, influenza, and tetanus. The antibodies used in passive immunization are typically derived from another organism, such as a human or animal. These antibodies work to provide immunity to the recipient by binding to specific disease-causing molecules and neutralizing their effects. This form of immunization is highly effective, providing nearly instantaneous protection from the disease in question and greatly reducing the risk of infection or re-infection. Passive immunization is beneficial in situations where an individual cannot be vaccinated or for diseases against which there is no vaccine available. Furthermore, it is also commonly used to prevent or treat illnesses in individuals who are immunosuppressed and cannot mount a normal immune response, such as those suffering from HIV or cancer.
