Vaccines help prevent people from getting sick.
They also help reduce the spread of disease to others and prevent epidemics. There are many kinds of vaccines. Each vaccine is made up of parts of weakened
or killed bacteria or viruses of a specific disease. After you have a vaccine,
immune system makes
antibodies to fight the disease. If you are exposed to
the same disease in the future, the antibodies kill the bacteria or viruses
before they have a chance to make you sick.
If you get a vaccine,
it may not completely prevent you from getting a disease, but it makes it much
less likely. If you get a disease even after you have been vaccinated, it
usually will be only a mild case.
