COVID-19 vaccines are safe, effective, free, and widely available. Everyone ages 6 months and up are now eligible for a COVID-19 vaccination, and you do not need an ID or insurance to get it. The COVID-19 vaccines are the best way to protect yourself, your family, and your community from COVID-19. For a better understanding of each of the available vaccines, the Food and Drug Administration (FDA) clinical trials, and the safety monitoring systems that are in place visit our COVID-19 Vaccine Safety and Effectiveness page.
Demographic information such as sex, race, and ethnicity are not required to be reported in the Wisconsin Immunization Registry (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.
Systemic barriers and social factors including access to quality health care, housing, transportation, and job opportunities, often referred to as systemic racism, has exacerbated the disparate impacts of COVID-19 experienced by Black, Brown, Indigenous, and other communities of color in Wisconsin, including disparities in vaccine rates. Through targeted distribution and strategic outreach with community stakeholders, Wisconsin is making deliberate choices to reduce barriers to access the COVID-19 vaccine and provide much-needed relief to communities that have withstood the worst of this pandemic.
Data on this page may differ from data reported on the Centers for Disease Control and Prevention (CDC) COVID Data Tracker due to the fact that data may be updated on different schedules and reflect data "as of" different dates or times of day. There may also be a delay between the time a vaccination record appears in the state system and when it is received by CDC. To learn more about vaccination data, visit our Frequently Asked Questions (FAQ) webpage.
We plan to update the data Wednesdays by 2 p.m.
As of September 14, 2022 DHS will no longer be reporting statewide COVID-19 illness after vaccination data. DHS recommends that anyone interested in breakthrough surveillance data visit the CDC data pages.
The CDC monitors rates of COVID-19 cases and deaths by vaccination status and reports data from various jurisdictions, including Wisconsin. The Rates of COVID-19 Cases and Deaths by Vaccination Status page shows the rates of COVID-19 cases and deaths among fully vaccinated people ages 5 and up as well as rates of COVID-19 cases and deaths among fully vaccinated people ages 50 and up with and without an additional booster dose and compare them to rates among unvaccinated people. On the Rate of COVID-19-associated hospitalizations by vaccination status page, you can explore COVID-19-associated hospitalizations by vaccination status and age groups.
Vaccines are one of the best tools we have to protect our communities against COVID-19. As with our other tools, vaccines work best when everyone gets them. DHS is working to get COVID-19 vaccine to Wisconsinites as equitably, quickly, and safely as possible.
This dashboard displays various data on COVID-19 vaccines administered to Wisconsin residents. It provides breakdowns of vaccines administered by county, healthcare emergency readiness coalition (HERC) region, age, sex, race, and ethnicity. The dashboard also presents the total number of doses administered to Wisconsin residents each week. Data in this dashboard represent the county or HERC region in which the individual who was vaccinated lives, not where they received their vaccine.
Percentages represent the vaccine coverage of the selected geography or demographic group. This helps us understand how well communities are protected from COVID-19. It also helps us see which areas and groups have fewer individuals being vaccinated so we can take action to help improve coverage and protect everyone from COVID-19. We use National Center for Health Statistics bridged-race population estimates 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. To account for the margin of error with these population estimates, we have capped the maximum vaccine coverage percentage at 95 percent.
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 all individuals who have received a COVID-19 vaccine. As patient information is updated or completed in WIR, we expect to see the number of vaccinations reported without demographic information to decrease.
Data source: The Wisconsin Immunization Registry (WIR)
Every Tuesday at 11:30 p.m. we extract vaccine administration data from WIR that will be reported on the DHS website by 2 p.m. the following day. WIR is a live system and providers are constantly sending immunization data. Therefore, data will look different if it is extracted at a different time of day.
Vaccination administration: The cumulative number of COVID-19 vaccines administered. The Vaccine Distribution Summary includes all vaccine doses administered by Wisconsin vaccine providers. This includes doses administered to people who resided out-of-state, but who live, work, or study in Wisconsin and qualify for vaccination in-state. This provides information to track the allocation, distribution, and administration of vaccine by Wisconsin's vaccinators. The COVID-19 Vaccines for Wisconsin Residents dashboard displays data for Wisconsin recipients of the vaccine. This information is used to inform vaccination coverage for the state.
Vaccine dose: One vaccine dose is one vaccine product (like a shot or a nasal spray). Some vaccines require two or more doses to protect you fully against a disease. Other vaccines give you enough protection to fight the disease after just one dose or shot.
Series completion: Many vaccines require multiple doses spaced out by weeks, months, or years to provide the best protection against a disease. Once someone receives the recommended number of doses within the correct timeframe, their series is considered complete.
A person can complete their Pfizer COVID-19 vaccine series if they get their second dose at least 21 days after their first dose.
A person can complete their Moderna COVID-19 vaccine series if they get their second dose at least 28 days after their first dose.
A person can complete their Johnson & Johnson COVID-19 vaccine series with only one dose. This means that doses of Johnson & Johnson will be counted in both categories of the COVID-19 Vaccines for Wisconsin Residents dashboard. Anyone looking at these metrics should not add the two together to get total doses administered. The "Completed series" totals are a subset of the "At least one dose" totals.
Vaccine locations: A doctor’s office, pharmacy, local or tribal health department, or other location where people can get their COVID-19 vaccines.
Vaccine record: A list of all vaccines an individual has received along with information about the vaccine, such as name of the vaccine and which provider gave the vaccine.
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 against COVID-19 so we can take action to help improve vaccination coverage and protect everyone from COVID-19.
Population estimates: U.S. Census Bureau annual state population totals.
Please note: Data reported prior to February 11, 2021, utilized population estimates from the Wisconsin Interactive Health Statistics (WISH) query system. These estimates use the U.S. Census, American Community Survey, and data from the Department of Administration to produce statewide and county-level population estimates by age groups, sex, race, and ethnicity for non-Census years. To promote transparency in the COVID-19 vaccination response and to allow for comparisons between states and other jurisdictions, DHS will now be using the same population estimates used by the CDC.
Data shown are subject to change. For more information, see the data FAQ. 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

One of the most effective ways to stop the spread of COVID-19 is to get vaccinated. COVID-19 vaccines are safe, effective, free, and now widely available.
