Differentiate between

Active immunity and passive immunity

Active immunity

Passive immunity

Active immunity is the immunity developed by an individual due to a previous infection or antigen which enters his body naturally

passive immunity is the immunity provided to an individual from an outside source in the form of ”ready-made” antibodies.

Example, a person who suffers from measles has active immunity

Example, maternal antibodies are transferred to the foetus through the placenta

The response is not immediate.

The administration needs to be systematic.
