COVID-19 vaccinations administered to Chicago residents based on the home Zip Code of the person vaccinated, as provided by the medical provider in Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE). The Zip Code where a person lives is not necessarily the same Zip Code where the vaccine was administered. Daily counts are shown for the total number of doses administered, first doses only, and number of people who have completed the necessary doses to be considered fully vaccinated. Cumulative totals for each measure as of that date are also provided. Requirements to be considered fully vaccinated vary depending on the vaccine manufacturer. Initial vaccines require two doses of vaccine to be administered over a period of time specific to each vaccine brand; future vaccines may only require one dose to be considered fully vaccinated. Vaccinations are counted based on the day the vaccine was administered.
Coverage percentages are calculated based on cumulative doses administered and cumulative number of people considered fully vaccinated in each Zip Code.
Population counts are from the U.S. Census Bureau American Community Survey 2015-2019 5-year estimates and can be seen in the Zip Code, 2019 rows of the Chicago Population Counts dataset (

All data are provisional and subject to change. Information is updated as additional details are received and it is, in fact, very common for recent dates to be incomplete and to be updated as time goes on. At any given time, this dataset reflects data currently known to CDPH.
Numbers in this dataset may differ from other public sources due to when data are reported and how City of Chicago boundaries are defined.
