Step-by-step explanation:
What is immunization?
=<Immunization is the process of giving a vaccine to a person to protect them against disease. Immunity (protection) by immunization is similar to the immunity a person would get from disease, but instead of getting the disease you get a vaccine. This is what makes vaccines such powerful medicine. Most vaccines are given by needle (injection) but some are given by mouth (orally) or sprayed into the nose (nasally). Immunizations are also called vaccinations, needles, shots or jabs.
How do vaccines work?
=Vaccines contain the same germ that causes disease. But the germs in the vaccine have been killed or weakened so that they do not make you sick. Some vaccines contain only a part of the germ that causes disease.
When you get immunized, your body is tricked into thinking that it has been infected with the disease. It makes antibodies that kill the germs. These antibodies stay in your body for a long time and remember how to fight the germ. If the germs from the disease enter your body in the future, the antibodies destroy the germs before you can become sick. It is much safer to get a vaccine than the disease.
