Answer:- The main difference between active and passive immunity is that Active immunity takes place when the host produces antibodies when exposed to pathogens or bacteria while passive immunity takes place when the host recieves antibodies from another source.
Hope this may be helpfull for u......
Active immunity- is usually permanent – it is produced by the antibodies of the host in response to direct contact of an antigen
Passive immunity- lasts only for a few weeks or months. It is produced by the introduction of antibodies from outside to the host
Active immunity-It produces an immunologicalmemory Passive immunity- It does not produce immunological memory
Active immunity-When the antigens enter the body, antibodies and other specialised lymphocytes are produced.
Passive immunity-Antibodies are introduced from an external source. For instance, a mother introduces antibodies to a fetus through the placenta and to an infant via mother’s milk.
Active immunity-There are no side-effects.
Passive immunity- It may cause reactions
Active Immunity-Immunity does not occur immediately.
Passive immunity- Immunity develops immediately
