Immunizations: Data

Vaccination rates look at the percentage of people who received recommended vaccines. This is also known as immunization rates or vaccination coverage. Vaccination rates are an important way to measure how well communities are protected from vaccine-preventable diseases. We offer reports that break down data by:

  • Vaccine/vaccine series
  • Demographics
  • Geography
  • Year

This helps us see which areas and groups have less protection. Health departments, schools, and partners can then take action to improve those vaccination rates.

The Wisconsin Immunization Registry (WIR) is our source for data on vaccine rates. We note any exceptions on the reports below.
