Immunizations: COVID-19 Vaccine Data

This dashboard provides breakdowns of vaccines administered to Wisconsin residents by county. Data in the map represent the county where the person who was vaccinated lives, not where they received their vaccine.

Percentages represent the vaccine coverage of the selected geography. This helps us understand how well communities are protected from COVID-19.

We use Wisconsin Interactive Statistics on Health (WISH) query system totals to calculate vaccine coverage percentages. Because these are estimates, and not exact counts, it is possible for vaccination counts to exceed population estimates for some groups.

Please note: Demographic data, such as sex, race, and ethnicity, are not required to be reported in WIR. Therefore, this data may not be available for everyone who received a COVID-19 vaccine. As patient information is updated or completed in WIR, the number of vaccinations reported without demographic information may decrease.

Data source: The Wisconsin Immunization Registry (WIR)

Vaccination administration: The cumulative number of COVID-19 vaccines administered.

Vaccine dose: One vaccine dose is one vaccine product (like a shot).

Vaccination coverage: An estimated percentage of the whole population who have received a COVID-19 vaccine. This helps us understand how well communities are protected from COVID-19. It also helps us see which areas and groups are less protected.

Population estimates: WISH query system totals. Data shown are subject to change. Some examples of corrections or updates that affect an area’s coverage include:

• Removing duplicates or merging and consolidation of records
• Updating a patient's address to a different county or state

This dashboard provides breakdowns of vaccines administered to Wisconsin residents by age, sex, race, and ethnicity. County breakdowns are shown for age and sex. At this time, data in WIR is based on sex (male/female) and does not capture gender identity. Additionally, race and ethnicity are documented separately in WIR, but combined for the data visualization.

*AI/AN includes American Indian or Alaska Native, Indigenous or Native American populations. Asian includes Asian, Native Hawaiian or Other Pacific Islander populations.

Demographic information, such as sex, race, and ethnicity, are not required to be reported in WIR. Additionally, WIR cannot store multiple race variables for a single vaccination record, regardless of how many are reported. As such, demographic breakdowns of vaccine administration by sex, race, and ethnicity may be incomplete. However, this data is a critical tool that provides insight into the vaccine program and helps inform decisions to ensure vaccine distribution is fair and equitable.

The first graph displays the cumulative count of vaccines administered to Wisconsin residents by age group.

The second graph displays the cumulative percentages of vaccine coverage by age group. Percentages help us understand how well age groups are protected from COVID-19.
