On Thursday, May 27, Cook County Health (CCH) will be consolidating its COVID-19 vaccine sites in Tinley Park, South Holland, and River Grove into its mass vaccination sites in Forest Park, Des Plaines, and Matteson. Cook County will be redeploying resources to support hyperlocal, community-based vaccination initiatives, as demand for vaccinations at mass sites wanes locally and across the country.

“Two thirds of Illinois residents have received their first dose of this life-saving vaccine, and we are moving forward with a granular focus on making vaccines as comfortable, convenient, and accessible as possible,” said Governor JB Pritzker. “That’s why we’re bringing vaccine to more and more doctor’s offices, pharmacies, urgent care clinics, and even directly into the community through mobile clinics that visit workplaces, neighborhood organizations, nonprofits and religious groups. Our fight to stay safe and protect ourselves and our loved ones isn’t over, but with each day and each dose, we move closer and closer to putting this pandemic to an end.”

More than 267,000 vaccine doses have been administered at the Tinley Park, South Holland, and River Grove sites since opening. In all, Cook County Health has administered more than 800,000 doses. Approximately half of all eligible suburban Cook County residents have received at least their first shot.

“It is critical that we continue to meet people where they are, either geographically or psychologically, to get them vaccinated,” said Toni Preckwinkle, President, Cook County Board of Commissioners. “This means going into neighborhoods and working with community-based organizations to ensure that everyone has access to the vaccine and that we can address the issues that cause people to be hesitant.”

The Cook County Department of Public Health (CCDPH) has identified 32 municipalities as vaccination priority areas based on the CDC’s social vulnerability index and the COVID-19 community vulnerability index. These communities, primarily in the west and south suburbs, are receiving additional resources through a variety of tactics to address vaccine hesitancy and availability.

“We have accomplished our first goal—vaccinate as many people as possible against COVID-19 with a large-scale strategy,” said Israel Rocha, CEO, Cook County Health. “The easy part is over. Most of the people who knew they wanted to get vaccinated have been vaccinated. Our focus is now on hearts and minds, educating and encouraging those who have not yet been vaccinated get their shot. This will require a very grassroots effort.”

CCH and CCDPH have already offered more than 200 pop-up, mobile and priority sites across the region to administer 86,000 doses to individuals in communities where they live and work.

The latest information about CCH vaccination sites is available at Walk-ins are welcome at all CCH mass vaccination sites. Individuals can still make appointments at or by calling 833-308-1988.
