Question

People administered with preformed antibodies get

• A. Active immunity
• B. Passive immunity
• C. Innate immunity
• D. Auto-immunity
• E. Natural-immunity

Answer 1

The correct option is B Passive immunity

• Passive immunity is the transfer of active humoral immunity of ready-made antibodies (exogenous) or preformed antibodies. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially when high levels of antibodies specific to a pathogen or toxin are transferred to non-immune persons through blood products that contain antibodies. People administered with preformed antibodies get 'Passive immunity'.
• So, the correct answer is 'Passive immunity'.
