COVID-19 Vaccine Administration Data
Data are reported based on the date IDPH receives vaccination reports from providers. Providers are to report as soon as practicable, but reporting can be delayed as much as 72 hours, which can lead to a lag between vaccines delivered to Illinois and vaccines administered.

Information provided in this section is provided by the Center for Disease Control and Prevention, which includes data available from federal programs not included in Illinois’ vaccine database. CDC reports the total number of people who reside in Illinois who have been vaccinated, including Illinois residents who have been vaccinated in other states. This data also includes vaccination records from Illinois’ vaccine database, I-CARE.

Booster Doses Administered
In early March 2022, a national database tracking COVID-19 vaccine experienced a change causing IDPH to update its procedures for pulling vaccine data from the database. As a result, the updated data pull was able to identify additional vaccine doses delivered to Illinois not previously captured. The Total Illinois Doses were update on the website on March 15, 2022 to reflect the change.

Jurisdiction-Specific Age Demographics
The bar graph shows all the doses of COVID-19 vaccine that have been administered in each county by age group. You can choose whether to look at the percent of the population with a single dose of vaccine administered or the percent of the population fully vaccinated.
Statewide Unusable COVID-19 Vaccine Doses
Reported to the Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE)
Unusable COVID-19 Vaccine Doses
Data to be updated weekly on Wednesday.
Unusable vaccine is generally defined as the number of doses discarded in opened or unopened vaccine vials that are not used to vaccinate an eligible individuals. This could be due to CDC guidance in opening a vial to vaccinate one or more individuals without recipients for all the doses in the vial at the time of opening, a dropped syringe, temperature deviation, expiration of the vaccine at its stored temperature, or other issues in the storage and handling process.
Data Definitions
State-Level Vaccination Summary
Total Doses – This is the total number of vaccine doses received in Illinois. This number includes doses allocated to Long-Term Care facilities, Retail Pharmacies, as well as doses shipped directly to providers and the Illinois Department of Public Health Strategic National Stockpile.
Total Administered Doses – This is the total number of doses (i.e. shots in arms) that have been reported to IDPH.
Administered Vaccines Data Details
Administered vaccines are reported as doses based on the individual’s county of residence. Some vaccines may be administered to people working in Illinois who live out-of-state. These vaccines will be included in the Illinois state total, but not in county-level totals. The Illinois-Comprehensive Automated Immunization Registry Exchange (I-CARE) http://dph.illinois.gov/topics-services/prevention-wellness/immunization/icare is the reporting system for automated submission of vaccine administration records. IL residents that are vaccinated in other states are not included in the Illinois total. Vaccines administered are reported by the number of doses and the number of people who are fully vaccinated.
Some vaccines require multiple doses over several weeks. Therefore, the number of doses will not equal the number of persons fully vaccinated. A person is considered to be fully vaccinated based on the type of vaccine. Initially available vaccines require 2 doses, but later vaccines may only require one dose.
The daily number of administered vaccines is reported based on the date IDPH receives the vaccination report and not the date of administration. COVID-19 vaccination providers must document vaccine administration in their medical record systems within 24 hours of administration, and use their best efforts to report administration data to the relevant system for the jurisdiction (i.e., IIS) as soon as practicable and no later than 72 hours after administration.
Population is defined as the entire population of the county. While vaccinations are currently limited to priority populations based on phases developed by the Advisory Committee on Immunization Practices (ACIP), eligibility will expand as more vaccine becomes available in Illinois. https://www.cdc.gov/vaccines/acip/index.html
Additional Notes
Due to ongoing data review and quality assurance efforts, data for previously reported COVID-19 vaccine doses administered are being continuously updated. Therefore, previously reported numbers may change to reflect the updated data. IDPH will continue to report the number of COVID-19 vaccine doses administered daily, but will also update these data twice a month.
On August 10, 2021, IDPH transitioned from including all vaccinations administered in Illinois, including those administered to people who live out of state, to reporting the number of Illinois residents who have been vaccinated in Illinois.
On August 31, 2021, IDPH reported that 122,680 vaccines administered on August 26, 2021. Of that total, 97,614 vaccinations were vaccines administered over the previous several months. For quality assurance purposes, a COVID-19 vaccine provider in Will County removed all previously reported vaccines administered and re-entered them, which is reflected in the August 26, 2021 data. While the vaccinations were removed from each day they were originally reported, they were re-entered on one day – August 26, 2021.
