CHICAGO — COVID-19 vaccination appointments at the United Center will open Thursday to all Illinois seniors.

Beginning Thursday at 8:30 a.m., seniors, age 65 and over, can schedule their first vaccine appointment at the United Center vaccine site.

Following this exclusive appointment period for seniors, all Illinoisans eligible under the state’s Phase 1B+ will be able to schedule appointments starting on Sunday, March 7 at 4 p.m.

A limited number of vaccines will be given at the site earlier than previously announced, starting Tuesday, March 9. A full opening begins on March 10.

The United Center site will have the capacity to administer 6,000 doses per day. More than 100,000 appointments over the next three days will be available when registration opens.

The vaccine will be offered at no cost, and insurance is not required. Documentation regarding immigration status is also not required.

Illinois residents have two options for making appointments: online and through a call center.

  • To register online, visit
  • To register by phone, call (312) 746-4835 from 8 a.m. to 8 p.m. Monday through Saturday and 8 a.m. to 4 p.m. on Sunday. Given the anticipated high demand for appointments, residents who can use the web site should book their appointments online.

The site will operate seven days a week for eight weeks under the federal government’s vaccination pilot program.

Uber is providing 20,000 $40 ride credits to eligible residents. After a Chicago resident books an appointment via Zocdoc, they will receive an appointment confirmation email which will also ask if they need transportation to their visit. If so, they’ll receive ride credits from Uber, which will work only for rides to and from the United Center.

City officials say there are still a quarter million seniors in Chicago who have yet to receive their first COVID-19 vaccination shot.

“Still, we don’t have enough vaccine for everyone who wants it but day-by-day, that calculus is improving,” said Commissioner of the Chicago Department of Public Health Dr. Allison Arwady.
