A total of 1,635,925 doses of vaccine have been delivered to providers in Illinois, including Chicago, with an additional 496,100 doses allocated to federal government partners for long-term care facilities, bringing the total number delivered in Illinois to 2,132,025.
IDPH reports that a total of 1,231,418 vaccine doses have been administered, including 188,351 at long-term facilities. The seven-day rolling average of vaccines administered is 49,082.
On Thursday, the state set a one-day vaccination record, with a total of 74,965 doses administered.
The IDPH says that vaccine distribution numbers are reported in real-time and vaccine administration numbers lag by as much as 72 hours.
Coronavirus testing sites in Chicago will be closed for "inclement weather," starting Friday.
City-operated testing sites will remain closed from Friday until Wednesday, according to a notification from the city.
Thursday's storm will be followed by a deep freeze that'll stretch into next week. Temperatures may not rise above the single digits, and wind chills may reach minus 30 degrees in what city officials called an "arctic blast."
Anyone who needs testing in the next few days should contact their healthcare provider.
"Honestly, form a safety perspective we don't want the staff and the volunteers potentially being exposed," said Dr. Allison Arwady, CDPH. "And there are walk-up availabilities at the site. We don't want people walking up."
Frigid conditions also prompted The Loretto Hospital on the West Side to move its walk-up testing indoors.
"We're actually converting our ground floor physical therapy room, which is pretty big and very spacious, into a COVID testing area," said Afya Khan, infection control practitioner at The Loretto Hospital.
The city's vaccination sites, which operate indoors, will remain open, as will the mass vaccination site at the Lake County Fairgrounds in Grayslake. Officials there said the need to rotate staff frequently out of the cold could cause delays.
Northwestern University Professor Hani Mahmassani, an expert in transportation and logistics, said vaccination clinics are likely to see some no-shows.
"There will be issues in staffing," she explained, "and also no-shows in terms of the patients. And in some cases, you do not want patients to come out in this weather, especially for some older folks who are the current group being vaccinated."
WATCH: More than 500 National Guard members helping vaccinate people
The commander of the Illinois National Guard said more than 500 National Guard members are part of the mission to vaccinate people in the state, and that number is expected to grow in the coming weeks.
Major General Richard Neely called it a unique position, but one the Guard is ready to handle.
"We're using our military skillsets to support the community, and so we'll continue to bring in Guard capability to surge in early," Major General Neely said.
Major General Neely said once commercial companies and other state contracts can catch up, then they'll take over vaccinations.
