PATHOLOGY

Detailed explanation-1: -Active Immunity-antibodies that develop in a person’s own immune system after the body is exposed to an antigen through a disease or when you get an immunization (i.e. a flu shot). This type of immunity lasts for a long time.

Detailed explanation-2: -IgA antibodies are transferred from mother to child in colostrum and milk and confer passive immunity. Passive immunity can also be in the form of IgA and IgG found in human colostrum and milk of babies who are nursed.

Detailed explanation-3: -Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.

Detailed explanation-4: -The difference between active and passive immunity Unlike active immunity, passive immunity provides immediate protection. But that protection is generally short-lived, as the supply of antibodies is not being replenished like they would be in someone whose own immune system was generating them.
