passive vs active immunity انواع المناعه المكتسبه
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.
Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
