Immunizations save lives. They are the best way to help protect you or your child from certain infectious diseases. They also help reduce the spread of disease to others and prevent epidemics. Most are given as shots. They are sometimes called vaccines, or vaccinations.
In many cases when you get a vaccine, you get a tiny amount of a weakened or dead form of the organism that causes the disease. This amount is not enough to give you the actual disease. But it is enough to cause your immune system to make antibodies that can recognize and attack the organism if you are ever exposed to it.

What are some reasons to get immunized?
Immunizations protect you or your child from dangerous diseases.
They help reduce the spread of disease to others.
They are often needed for entrance into school or day care. And they may be needed for employment or for travel to another country.
Getting immunized costs less than getting treated for the diseases that the shots protect you from.
The risk of getting a disease is much greater than the risk of having a serious reaction to the vaccine.
When immunization rates drop below a certain level, preventable diseases show up again. Often, these diseases are hard to treat. For example, measlesoutbreaks still occur in the U.S.
If you are a woman who is planning to get pregnant, talk to your doctor about what immunizations you have had and what you may need to protect your baby. And if you live with a pregnant woman, make sure your vaccines are up-to-date.
Traveling to other countries may be another reason to get immunized. Talk with your doctor months before you leave, to see if you need any shots.
