1.If a person is infected with some deadly microbes, a quick immune is required; as in tetanus, we need to directly inject the preformed antibodies or antitoxin.
2…Even in case of snake bites, the injection given to the patients contains preformed antibodies against the snake venom.
This type of immunization is called passive immunization.
