Natural immunity.
Naturally acquired active immunity
Active immunity will generally occur when a person is exposed to pathogens. This will happen when a disease develops as a result of agents that cause diseases.
active immunity is the immunity that is stimulated internally as a a result of antibodies entering the body. Passive is stimulated by substances from an external source
Active immunity is of two kinds: Natural active immunity: This is acquired when a pathogen enters the body and immune response occurs. This is stored by the memory cells and eliminates the pathogen for the second time as soon as it enters the body. Acquired active immunity: This artificial and it is induced through a artificial source like vaccines.
Active immunity is generated by your body. So you get active immunity as a result of infections or due to vaccines. Passive immunity is not generated by your body. Here the antibodies are to be supplied. Child gets the antibodies from mother. Alternately you get the antibodies via injections. The effect of active immunity is long lasting. The effect of passive immunity is short lived. So the active immunity is considered as better. The passive immunity has one advantage. It is available with immediate effect, while it takes about two to three weeks, before the effects of active immunity is available.

Active immunity is when the body produces its own antibodies in response to an antigen, providing long-lasting protection. Passive immunity is when antibodies are transferred from one individual to another, providing immediate but temporary protection.
