Community Health Network's nurses volunteered to staff clinics providing vaccines to the community. On normal days, the gym at this Indianapolis school would be filled with kids in phys ed classes. But last Saturday it was the scene of a pop-up vaccination clinic. And the mood was just as up-beat. One nurse brought her husband to the KIPP Indy Legacy High School to get vaccinated — to cheers from everyone around. At the entrance to the gym, volunteers used laptops to help people check in. Most got their shots without a wait. After all, community workers had pre-registered 200 area residents to make the experience as easy as possible.
