Vaccine update: As of Sunday, IDPH reported a total of 10,913,325 doses of COVID-19 vaccines have been distributed statewide, with 8,810,463 vaccines administered.

As of the time this story was published, 3,769,787 of the population of Illinois have been fully vaccinated, or 29.59%. Illinois has a population of 12,741,080 people.

There can be as much as a 72-hour delay in reporting from healthcare providers on vaccines administered.

In northern Illinois, here is the percentage of the population fully vaccinated by county:

Cook: 30.77%

Lake: 26.50%

McHenry: 25.77%

DuPage: 32.81%

Kane: 25.97%

Will: 26.46%

Kendall: 27.07%

Bureau: 26.47%

Bridge update: According to Gov. JB Pritzker’s plan announced March 18, the state needs 70% of Illinois residents ages 65 and older to have received at least one dose of a COVID-19 vaccine before it can advance to the state’s “bridge plan” that will open up capacity limits on all businesses. The state’s bridge plan remains on pause because of a continued rise in COVID-19 hospitalizations.

As of Sunday, 78.23% of those 65 and older had received one dose of the vaccine, according to the state’s dashboard.

Also, according to the state’s dashboard, 52.36% of Illinois residents 16 and older have received at least one dose of a COVID-19 vaccine.

Regional update: Currently, all 11 of the state’s health regions are in Phase 4 of the state’s reopening plan.

For regions experiencing a resurgence of COVID-19, Tier 1 mitigations may be applied in either of these two scenarios:

  • If a region’s test positivity rate is greater than or equal to 8% for three consecutive days (measured with the 7-day rolling average).
  • If a region experiences both a sustained increase in test positivity rate (measured with the 7-day rolling average for 7 of 10 days) and hospital capacity is threatened, which is measured by either:
    • A sustained increase in the number of COVID-19 patients in the hospital (measured with the 7-day average for 7 of 10 days), or
    • Staffed ICU bed availability falls below 20% for three consecutive days (measured with the 7-day rolling average).

Regional data from the IDPH remains on a three-day lag.
