||Produced actively by the immune system of the host.
||Received passively by the host and the host immune system does not participate.
||Induced by infection or by contacts with immunogens.
||Conferred by introduction of ready-made antibodies.
||Immune response is durable and effective.
||Immune response is short lived and less effective.
||Immunity develops only after a lag period.
||Immunity effective immediately.
||Immunological memory present due to presence of memory cells.
||No immunological memory.
||Subsequent challenge with booster dose more effective.
|| Subsequent administration of antibody is less effective due to immune elimination.
||After antigenic stimulus, negative phase may occur due to antigen combining with any pre-existing antibody in blood.
|| No negative phase is present here.
||Serves no purpose in immuno-defecient host.
|| Applicable in immuno-defecient host.
||Used for prophylaxis to increase body resistance.
|| Used for treatment of acute infection.
||Side effects are very low.
|| The body may react to antisera.
||Artificial active immunity is induced by vaccination.
||Artificial passive immunity is induced by injection of antibodies.
||A lag period is present.
A lag period is absent.
