Different type between active immunity and passive immunity
Answers
passive immunity is developed when antibodies are injected into the body and it offers immediate resistance where as in active immunity the body itself produces antibodies against antigen.here an immediate response is not seen but the immunity offered is long lasting
Some points about active immunity are as follows:-
1. It is produced actively by the immune system of the host.
2. Induced by infection or by contacts with
immunogen, e.g. vaccines.
3. Immune response-durable and effective.
4. Immunity develops only after a lag period.
5. Immunological memory present.
6. Serves no purpose in immunodeficient host.
7. Used for prophylaxis to increase body resistance.
Some points about passive immunity are as follows:-
1. Received passively by the host and the host's
immune system does not participate.
2. Conferred by introduction of ready-made
antibodies.
3. Immune response-short lived and less effective.
4. Immunity effective immediately.
5. No immunological memory.
6. Applicable in immuno deficient host.
7. Used for treatment of acute infection.
