Difference Between Active and Passive Immunity
Questions › Difference Between Active and Passive Immunity - Active immunity is developed naturally or artificially by the body’s immune system, while passive immunity is acquired artificially through the transfer of antibodies from another individual.
- Active immunity requires exposure to an antigen, either naturally or through a vaccine, while passive immunity does not require exposure to an antigen.
- Active immunity takes time to develop, while passive immunity provides immediate protection.
- Active immunity is long-lasting, while passive immunity is temporary.
- Active immunity is specific to the antigen encountered, while passive immunity provides broad-spectrum protection.
- Active immunity involves the production of memory cells, which provide long-term protection against future infections, while passive immunity does not involve the production of memory cells.
- Active immunity may result in an allergic response, while passive immunity does not.
- Active immunity requires the body to mount a response, while passive immunity does not.
- Active immunity is effective against intracellular pathogens, while passive immunity is effective against extracellular pathogens.
- Active immunity is more effective at preventing future infections, while passive immunity is more effective at treating current infections.
- Active immunity is generated by the body’s own immune response, while passive immunity is generated by the immune response of another organism.
- Active immunity develops slowly over time, while passive immunity is immediate.
- Active immunity is the result of exposure to the antigen, while passive immunity is the result of receiving pre-formed antibodies.
- Active immunity requires an active response from the body, while passive immunity does not require an active response.
- Active immunity may result in booster shots being required to maintain protection, while passive immunity does not require booster shots.
- Active immunity is generated by the body’s immune response, while passive immunity is generated by the transfer of antibodies.
- Active immunity involves the production of antibodies by the body, while passive immunity involves the transfer of antibodies from another organism.
- Active immunity requires time for the immune response to develop, while passive immunity provides immediate protection.
- Active immunity may be lifelong, while passive immunity is temporary.
