Suburban Cook County opened its first mass vaccination site at the Tinley Park Convention Center on Tuesday, Jan. 26. Nearly 7,000 vaccines were administered at the convention center during the first week in operation, health officials said.

At Triton College, "when fully operationalized and when ample vaccine supply becomes available," more than 4,000 vaccines are expected to be administered weekly.

Vaccinations at all Cook County Health sites are by appointment only. Additional large vaccination sites throughout the county are expected to open in the following weeks.
