WAUWATOSA, Wis. - The Wauwatosa Health Department on Monday, Feb. 22 began testing the Wisconsin COVID-19 Vaccine Registry. It's all in an effort to streamline the vaccination process -- giving people a place to sign up for an appointment for their shot. Trying to figure out how to get a COVID-19 vaccine and where to get a vaccine when you're eligible is a common frustration for many, but this new registration system could help. Nearly two handfuls of local health departments across the state are testing the pilot vaccine registration program, including in Wauwatosa.
