Cook County will offer vaccinations without appointments at two of its mass vaccination sites as part of a pilot program running through Saturday.

Vaccinations were previously available by appointment only at the Matteson and Tinley Park sites.

“Nearly 40% of eligible Cook County residents have received at least one shot. We are proud of all we have accomplished so far and will not rest until we ensure that all residents have had the opportunity to get vaccinated,” Cook County Board President Toni Preckwinkle said in a written statement.

“We all know that the pandemic has disproportionately impacted communities of color and those groups are also most hesitant to get the vaccine. It is critical that we remove any and all barriers to vaccination.”

The two sites are open 8:30 a.m. to 5:30 p.m. Wednesday through Saturday for walk-ins and for those with appointments, county officials said. A photo ID is required. Those younger than 18 must be accompanied by an adult. People can make appointments online at or by calling 833-308-1988.

The Tinley Park site at 18451 Convention Center Drive has a supply of Moderna vaccine. The Matteson site at 4647 Promenade Way has a supply of Pfizer vaccine. The Pfizer vaccine is the only one approved for 16 and 17 year olds.
