Why Immunize?

Immunization is one of the most important ways to protect individuals and communities against serious infectious diseases and their consequences. Widespread immunization has virtually eliminated many serious diseases that were once responsible for millions of infections and thousands of deaths each year. Such diseases include polio, measles, meningitis caused by haemophilus influenzae type B (Hib), congenital rubella, diphtheria, and smallpox.

The vaccines a child receives are highly effective. Most children who receive these vaccines will be fully protected. However, the vaccines do not "take" in some children. Even these children who do not develop full immunity will benefit from vaccines. Some will experience a milder form of the disease, and because other people in their community are being immunized, all children are less likely to be exposed to the diseases. For some children, those with cancer or weakened immune systems, vaccination is not a safe option. These children depend on community or "herd" immunity to help prevent them from becoming infected by a disease their body would have difficulty fighting. 

Your child's chances of being harmed by these diseases are far greater than any chance of being harmed by the vaccines. Immunizations are one of the most important ways parents can protect their children against serious diseases. Although vaccine-preventable diseases such as measles and polio are rarely seen in the U.S., they continue to flourish in other parts of the world that are only a plane ride away. Recent outbreaks of pertussis, measles and mumps remind us of the importance of immunizing children.

Science continues to bring us new vaccines to protect against disease. When new vaccines offer new protections, medical experts recommend changes.
