Immunizations allow us to prevent illnesses caused by certain infectious diseases. This is important, as many infectious diseases do not have effective treatments and can cause serious complications and even death in otherwise healthy individuals. Therefore, prevention is the best treatment, and immunizations have a proven track record of being safe and effective for this purpose.
Diseases that can be prevented with vaccines can be very serious -- even deadly -- especially for infants and young children. In fact, immunization is one of the best ways parents can protect their infants from 14 serious childhood diseases before the age of two. Immunizations have helped to greatly improve the health of children in the United States. Most parents today have never seen firsthand the devastating consequences that vaccine-preventable diseases have on a family or community. Although most of these diseases are not common in the United States, they persist around the world. It is important that we continue to protect our children with vaccines because outbreaks of vaccine-preventable diseases can and do still occur in this country.
