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.
