Vaccinations can help protect your child from serious diseases caused by germs. Vaccinations are also called vaccines, immunizations, needles, or shots.

Vaccinations work by boosting the immune system's ability to fight certain infections. The vaccination teaches your child's immune system to recognize and fight specific germs so that when they are exposed to them, he or she has a much lower risk of getting sick.
