Cook County Board President Toni Preckwinkle and Cook County Health CEO Israel Rocha were joined by Governor J.B. Prtizker to announce that the Tinley Park Convention Center will serve as Cook County’s first large-scale vaccination site opening the week of January 25th to continue Phase 1a and begin Phase 1b vaccinations. Phase 1b includes individuals age 65 and older and essential workers such as first responders, manufacturing employees and grocery store personnel. While an estimated 600,000 suburban individuals are eligible for vaccine under Phase 1b, officials warn there is currently not adequate vaccine supply to vaccinate everyone.   Vaccinations at Tinley Park and other Cook County Health sites will be provided by appointment. Individuals in 1b can schedule an appointment at vaccine.cookcountyil.gov. Individuals without internet access or who need assistance scheduling can call (833) 308-1988 (from 7a.m. to 7p.m., Monday – Friday). Cook County Health will only offer appointment slots based on the amount of vaccine on hand and will add appointments as new vaccine shipments arrive.
