  9. Immunity • Acquired immunity • Developed after the body has overcome a disease or through inoculation • Disease or inoculation causes the blood cells to produce antibodies which are proteins that fight disease germs • May be temporary or permanent • Human disease carrier • One who is personally immune to a disease but can transmit germs to others • Typhoid fever & diphtheria can be transmitted this way
