COVID-19 Vaccine Coverage

COVID-19 Vaccine Coverage

CDPH has been monitoring COVID-19 vaccine coverage by demographic groups and geographic areas in the city since COVID-19 vaccines became available in December 2020. Initial vaccine rollout focused on those aged 65 and older and essential workers. Over time those eligible has expanded, and all Chicagoans aged 6 months and older are now eligible for vaccination.

For more detailed information about the data, including sources and definitions see About the data.

COVID-19 vaccinations among Chicago residents

This table shows the number and percent of Chicago residents who are vaccinated for COVID-19. Updated, bivalent doses became available in Fall 2022 and were created with the original strain of COVID-19 and newer Omicron variant strains.

Data displayed are cumulative totals through the most current date. Use the date filter on top of the table to look at totals at prior dates.

Vaccination coverage percentages are not calculated for race-ethnicity groups with small populations in Chicago. Differences in how race-ethnicity data are collected on vaccination forms and the U.S. Census may result in over or under estimates of coverage in these groups.

COVID-19 vaccinations by demographic group

The chart below shows the percent of Chicago residents vaccinated for COVID-19 by demographic group. This metric is also referred to as vaccination coverage.

Data displayed are coverage estimates through the most current date. Use the date filter on top of the chart to look at coverage estimates at prior dates.


The charts below show the percentages of Chicago residents vaccinated for COVID-19, by age and race-ethnicity subgroup and vaccination status. The dashed line displays the citywide coverage estimate for each age group and vaccination status.

Use the filters to the right of the charts to display coverage estimates for different age groups. Use the button at the top right to switch between displaying the data in chart or table format.

Data are updated Wednesdays at 5:30 p.m. and reflect coverage rates through the previous Saturday.


COVID-19 vaccination trends

This graph shows the percentages of Chicago residents with each vaccination status over time. Original booster/additional dose refers to people who received an additional monovalent vaccine dose after completing their primary seriesThis includes first monovalent booster doses and additional doses for people who are immunocompromised. Monovalent vaccines are the first vaccines that were created from the original strain of the virus that causes COVID-19. Updated (bivalent) booster dose refers to people who have received an updated (bivalent) COVID-19 vaccine dose that became available in Fall 2022. Use the filter on the right to see how coverage has changed over time among different demographic groups.


This graph shows the 7-day rolling average number of Chicago residents who received a first dose of COVID-19 vaccine, completed a primary series, or received a booster/additional dose, or an updated (bivalent) booster dose of vaccine. A rolling average smooths out day-to-day jumps, but still provides current information about vaccine administration. Use the filter on the right to see these trends among different demographic groups.


Vaccine data come from the Illinois Comprehensive Automated Immunization Registry Exchange (ICARE). I-CARE includes doses administered in Illinois and some doses administered outside of Illinois and reported in I-CARE by Illinois providers. Doses administered by the federal Bureau of Prisons and Department of Defense are not currently reported in I-CARE. The Veterans Health Administration began reporting doses in I-CARE beginning September 2022.

The Chicago Department of Public Health uses the most complete data available to estimate COVID-19 vaccination coverage among Chicagoans, but there are several limitations that impact our estimates. Due to people receiving vaccinations that are not recorded in I-CARE and linked to their record, such as someone receiving a vaccine dose in another state, the number of people with a completed primary series or a booster dose is underestimated. Inconsistencies in records of separate doses administered to the same person, such as slight variations in dates of birth, can result in duplicate first dose records for a person and overestimate of the number of people with at least one dose and underestimate the number of people with a completed primary series or booster dose.

More detailed descriptions of the data and downloadable files are available on the Chicago Data Portal.

Vaccination status definitions:

  • At least one dose: People who received at least one dose of a COVID-19 vaccine (includes people that have received > 1 dose of vaccine)
  • Completed primary series: People who have completed a primary series of COVID-19 vaccination.
  • Original booster/additional dose: People who have received another dose of a monovalent COVID-19 vaccine after being completing their primary series. This includes booster doses and additional doses for people who are immunocompromised. Monovalent vaccines are the first vaccines that were created from the original strain of the virus that causes COVID-19.
  • Updated (bivalent) booster dose: People who have received an updated (bivalent) COVID-19 vaccine dose. Updated, bivalent doses became available in Fall 2022 and were created with the original strain of COVID-19 and newer Omicron variant strains.

Coverage estimates by age and race-ethnicity are capped at 99%. Actual counts may exceed population estimates and lead to >100% coverage, especially in small race-ethnicity subgroups of each age group.

Population estimates:

Unless otherwise specified, population denominators are from the U.S. Census Bureau American Community Survey 1-year estimate for 2019 and can be seen in the Citywide, 2019 row of the Chicago Population Counts dataset.

Population denominators for coverage data by age and race-ethnicity groups are included within the COVID-19 Vaccinations by Age and Race-Ethnicity dataset.  

Chicago COVID-19 Community Vulnerability Index (CCVI)

Chicago CCVI helps identify Chicago communities that have been disproportionately impacted by COVID-19 and are uniquely vulnerable to barriers to COVID-19 vaccine uptake for focused intervention.
