A person who is exposed to a disease and who is subsequently injected with antibodies produced by others has been given

This is an example of passive immunity. Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. For example measles antibody will protect a person who is exposed to measles disease, but will have no effect if they are exposed to another disease. There are two types of immunity, namely; passive and active' Active immunity results when exposure to a disease triggers the immune system to produce antibodies to that disease. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
