passive immunization
passive immunity is the transfer of active humoral immunity of ready-made antibodies. passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserum therapy. passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases. passive immunization can be provided when people cannot synthesize antibodies, and when they have been exposed to a disease that they do not have immunity against.
passive immunity
immunity developed as an individual is exposed to antigens is called adaptive or acquired immunity, in contrast to immunity developed at birth, which is innate immunity. acquired immunity depends upon the interaction between antigens and a group of proteins called antibodies produced by b cells of the blood. there are many antibodies and each is specific for a particular type of antigen. thus immune response in acquired immunity is due to the precise binding of antigens to antibody. only very small area of the antigens and antibody molecules actually interact through complimentary binding sites, called epitopes in antigens and paratopes in antibody.
