Wisconsin Immunization Program

General information

Immunizations, also called vaccinations, are one of the greatest achievements in public health. Vaccines prevent disease in people who receive them. Additionally, if enough people in the community are vaccinated, the entire community can be protected because there is little opportunity for an outbreak to occur.

Before vaccines, many children died from diseases like measles, pertussis (whooping cough), and Haemophilus influenzae. Through the introduction of routine vaccinations, these and other vaccine-preventable diseases occur much less often in the United States. However, the viruses and bacteria that cause these diseases still exist. Vaccinations are the best way to prevent these diseases and the serious effects they can cause.
