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.

Data is provisional. Last Updated: ##/##/####

These vaccine data are pulled from I-CARE and do not reflect federal efforts to vaccinate Illinoisans. 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.

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.

#% of COVID-19 Deaths Since January 1, 2021

Data to be updated weekly on Wednesday.

Breakthrough is defined as an individual who tests positive for COVID-19 at least 14 days after being fully vaccinated and did not test positive in the previous 45 days.

Following CDC, IDPH is reporting only patients with COVID-19 vaccine breakthrough infection that were hospitalized or died to help maximize the quality of the data collected on cases of greatest clinical and public health importance.

Statewide Unusable COVID-19 Vaccine Doses

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 a dropped syringe, temperature deviation, expiration of the vaccine at its stored temperature, or other issues in the storage and handling process.

Percent of Age Group Population Fully Vaccinated


The bar graph shows all the doses of COVID 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. The purple stacked bar provides the percent of the people in the county who are 65 years of age and older with doses administered. If looking at the chart showing at least one dose of vaccine, this would be the number of people 65 years of age and older who have received at least one dose of vaccine divided by the total population of people 65 years of age and older who live in that county. That is multiplied by 100 to create a percentage. The blue stacked bar provides the same information about people 16 years of age through 64 years of age in that county.

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) 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.
