Which ability prevents some people from getting a particular disease while others get easily affected?
Immunity
∙The ability of an organism to resist disease, either through the activities of specialised blood cells or antibodies produced by them is termed as immunity.
∙Immunity to a disease is achieved through the presence of antibodies to that disease in a person's body.
