Sound truck to deliver COVID-19 vaccine message to Baltimore residents

The Maryland Department of Health is redeploying its sound truck to reach residents in five key Baltimore City ZIP codes over the next five days. Officials said the effort has worked before, and so the MDH is doing it again -- redeploying its sound truck in Baltimore City to reach residents in key ZIP codes. Starting Wednesday through the Memorial Day holiday weekend, a sound truck outfitted with banners and big speakers will blast a message across five city ZIP codes that data shows have high COVID-19 case numbers and low vaccine uptake.
