Types of adaptive immunity
•Active– reaction of your
own system
•Passive– borrow immune agents from another
person

Types of adaptive immunity
•Natural – occurs accidentally, on its own –Active – you are exposed to the
flu, then develop immunity to that flu strain
–Passive – a fetus receives antibodies from mom
•Artificial – stimulated on purpose–Active – vaccination with a killed
virus triggers immunity to the live virus
–Passive – Injection of antibodies provides immunity

Inappropriate immunity
• Autoimmunity – “self” cells are attacked (abnormal)
• Allergy (Hyperimmunity) – excessive response to antigen, or response to something not normally an antigen (allergen)
