OTHER PROTECTIONS FROM GERMS
Immunization will protect you from developing certain diseases even after the germs have gained a foothold in your body. For example, tetanus germs can be conquered by injections given between the time they start to grow and the time they cause the symptoms of illness to appear. Never delay getting treatment if you have any reason to suspect these germs have entered your body.
Injections will help the body to win its battle against certain diseases even after the illness is under way. In diphtheria, for example, the antitoxin can be injected to neutralize the toxic effect of the germs.
Some chemical substances used to destroy germs are quinine that attacks malaria germs, a compound of arsenic that strikes at the germs causing syphilis, and the sulpha medicines that destroy several kinds of germs. Antibiotics such as penicillin act in a slightly different manner: they make it impossible for certain very dangerous germs to grow; the germs rapidly weaken and are overcome by the resistance of the body to microbes.
