Your body prevents harmful microorganisms entering and causing harm. The
skin, for example, doesn't allow microorganisms to enter. Hairs and mucus in your nose catch invaders, and then you push themucus out when you cough, sneeze or blow your nose. Enzymes and acids in the body, and white blood cells also destroy bacteria.
Do antibiotics help ? Doctors use antibiotic drugs to fight bacterial infections, but antibiotics don't work
against viruses. This is why doctors don't give antibiotics to patients with a
common cold or flu.
How does immunization work ? Immunization
(or vaccination) is another way of protecting the body, by injecting the body with
dead or inactive microorganisms. After vaccination, the body starts to
make antibodies that destroy the microorganism. Because the microorganisms in the
vaccination are not dangerous, the person doesn't getill. When they come
into contact with a live (dangerous) micro organism, then the antibodies
destroy the infection before it makes them ill.
