Answer
The difference between active and passive immunity is that active immunity is created when a person's own immune system produces antibodies against infectious agent. It can be naturally acquired (person is exposed to infectious agent) or artificially acquired (through vaccine or immune serum). Whereas, passive immunity is created when artificially made antibodies are introduced into the person's body. It can be naturally acquired (transfer of mother's antibodies to her offspring) and artificially acquired (introduction of antibodies made by a host to a new host).
