The Chicago Department of Public Health and Cook County Department of Public Health both announced that they support the Center for Disease Control’s decision to recommend COVID-19 booster shots for all adults 18 and older who were previously vaccinated. The city health department is “ordering more vaccine from the federal government in anticipation of increased demand and remind Chicagoans that they can get a dose at sites across the city — in hospitals, physicians’ offices, local pharmacies, pop-up clinics hosted by the City, and more,” according to a release sent Friday. A full list of city-backed vaccination sites is available online.
