The United Center has been transformed into the state’s largest mass-vaccination site, with sprawling tents capable of up to 6,000 shots per day.

Gov. JB Pritzker said Tuesday, the vaccines given at the United Center will helpbuild on our current state average of more than 90,000 shots put in arms, every day.”

The city says from check-in to vaccination, people should expect about 45 minutes. The entrance is in Lot E at Wood and Madison streets.

Mayor Lori Lightfoot said appointments will be set aside for residents who live in “high COVID community vulnerability index neighborhood zip codes” and zip codes with low vaccination rates. 

“In order for us to truly rise and recover from this pandemic, we knew that we had to continue to push vaccines to residents that need it most, especially those 65 and older, as fast as humanly possible,” Lightfoot said.That’s why we’re thrilled to announce that starting today the United Center vaccine site is officially open.”

The vaccine site is walk-through only for at least the next two weeks. There will be on-site parking, but people are encouraged to get dropped off or take public transit if they can.

Lightfoot said the site was designed withdisability in mind.” She said the new site is fully accessible so that anyone with a disability can get a vaccine in comfort.

Last week, President Biden said that he believes that every American adult who wants a vaccine will be able to receive one by the end of May. Believe me, I look forward to that day,” Cook County Board President Toni Preckwinkle said Tuesday.  “I’m proud of the progress we’ve made in our vaccination programs and have enjoyed visiting the sites around the county.”
