COVID-19 Vaccine Data

COVID-19 Vaccine Data

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 5 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. Booster/additional dose refers to people fully vaccinated who have received another dose of a COVID-19 vaccine. This includes first booster doses and additional doses for people who are immunocompromised.

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. ‚Äč

Doses given to Chicago residents

There are currently three vaccines that are available to Chicago residents-Pfizer, Moderna, and Johnson & Johnson (also called Janssen). Pfizer and Moderna require two doses, while Johnson & Johnson requires one dose. This graph shows the 7-day rolling average number of Chicago residents who have received at least one dose of vaccine or have completed a vaccine series. A rolling average smooths out day-to-day jumps, but still provides current information about vaccine administration.

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 federal agencies, like the Veterans Health Administration, are not currently reported in I-CARE.

The Chicago Department of 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 (i.e., two doses of Pfizer or Moderna or one dose of the Johnson & Johnson vaccine).
  • Boosted/additional dose: People who have received another dose of a COVID-19 vaccine after being fully vaccinated. This includes first booster doses and additional doses for people who are immunocompromised.

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.

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.
