The Rock County Health Department is promoting expanded hours at the COVID-19 immunization clinic in Janesville. Health Department Communications Specialist Jessica Turner says the hours should make it more convenient for people to get immunized, now that the FDA has authorized COVID-19 booster shots for all adults. The new hours at the AMI-hosted Community Based Clinic will be Tuesday through Friday from 11:00 a.m. to 7:00 p.m. and Saturdays from 11:00 a.m. to 3:00 p.m. The expanded hours will begin next week and run through the end of the year. The clinic is located in the former Rock County Job Center at 1900 Center Avenue in Janesville.
