Treatment of snakebite by antivenom is considered as ______________ .
Artificially acquired passive immunity
Passive immunity can be induced artificially when preformed antibodies are given as medication to non-immune individuals. Passive immunization is quick acting and can provide an immune response within hours, faster than a typical vaccine. In case of snakebites, the antivenom administered to the patient contains preformed antibodies against the snake venom. So, treatment of snakebite with antisnake venom is artificially acquired passive immunity.
