Vaccines Vaccines resolve this delicate situation. Vaccines contain the same germ that causes the disease. This germ has been either killed or weakened to the point that it does not make your child sick. The vaccine stimulates the immune system to produce antibodies, exactly like it would if the child gets exposed to live germs. The child will develop immunity to that disease and, best of all, doesn’t have to get sick in the first place. This makes the vaccines such potent medicine. It won’t be wrong to say that most children get fully protected after receiving the vaccines. It means that they will never get serious diseases or infections if they are immunized against vaccine-preventable diseases. Our immune system is designed to protect us from anything foreign that enters our body. When a disease-causing organism enters the body, the immune system recognizes it as “non-self” and produces antibodies to get rid of it. leave the child resistant to future infections, but not before the child gets sick with that infection. Put simply, the child must get sick before developing immunity. 12
