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.
Data pages
RSV immunization data
The Department of Health Services (DHS) reports on RSV immunization for infants ages 0 to 19 months and adults ages 18 to 49 and 60+ years.
COVID-19 vaccination data
DHS reports on updated COVID-19 vaccination for Wisconsin residents 6 months and older.
Impact of COVID-19 on routine vaccination
The COVID-19 pandemic caused many children and teenagers to fall behind schedule for vaccines. This dashboard compares quarterly vaccination rates to the average rates of the three years before the pandemic.
Flu vaccination data
DHS reports on flu vaccinations for people at least 6 months old who have received at least one dose of flu vaccine during the season.
