The pilot program by the Cook County Health and Hospitals System and the Cook County Department of Public Health debuted by inoculating a hundred residents, caregivers and employees at the Garden House of Maywood, a Housing and Urban Development-subsidized senior home, with the Johnson & Johnson vaccine. Over the next weeks, nurses will head to other sites that have partnered with the county and serve suburban residents in phase 1b, which includes people 65 or older, front-line essential workers and those in congregate living settings.
