Therefore, by exposing associate to antigen in an exceedingly controlled manner, its body will learn to shield itself: this can be referred to as active immunization. The most necessary components of the system that can be improved by immunization square measure the T cells, B cells, and therefore, the antibodies B cells turn out. Memory B cells and memory T cells square measure chargeable for a swift response to a second encounter with a remote molecule. Passive immunization is the direct introduction of those components into the body, rather than the production of those components by the body itself.
