Jane Carlson and Leslie Renken USA Today Network GALESBURG — Illinois college students are next in line to receive the COVID-19 vaccine after dozens of county health departments — outside of Chicago and Cook County — recently broadened eligibility to all residents over 16. Some Illinois colleges and universities already are offering shots on campus, while some students are scouring local pharmacies and county-run sites for appointments. But the big question — will area schools require the vaccine? — remains unsettled for most institutions. Western Illinois University is offering vaccine clinics for students. At this point, student participation is voluntary, according to university spokesperson Darcie Shinberger.
