Vedclass · Answer

(A) The principle of Vaccination and Immunization is based on the property of 'memory' of the immune system.In vaccination,a preparation of antigenic proteins of pathogens or inactivated/weakened pathogens (vaccine) is introduced into the body.The antibodies produced in the body against these antigens neutralize the pathogenic agents during an actual infection.The vaccine also generates memory $B$ and $T$ cells that recognize the pathogen quickly upon subsequent exposure and overwhelm the invaders with a massive production of antibodies.If a person is infected with deadly microbes for which a quick immune response is required,such as in tetanus,we need to inject preformed antibodies or antitoxins.In the case of a snake bite,the injection given to the patient contains preformed antibodies against the snake venom. This type of immunization is called passive immunization.
