The adaptive immunity has two further classes, the active immunity and the passive immunity. Active immunity: Passive immunity: It is produced due to contact with pathogen or antigen. A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body. No antibody is produced, but directly transferred. Active immunity takes place when the host produces antibodies when exposed to pathogens or bacteria while passive immunity takes place when the host receives antibodies from another source.
