SEATTLE (AP) — Gov. Jay Inslee and Seattle-area leaders are touting the opening of a new mass COVID-19 vaccination site at an event center between the city’s two sports stadiums – a site authorities hope can soon be vaccinating more than 20,000 people a day, seven days a week. The site at the Lumen Field Event Center will open Saturday. As more vaccine doses become available officials say the Lumen site will be able to operate seven days a week and innoculate 22,000 people each day. Seattle Mayor Jenny Durkan said at full capacity the operation will be the the largest civilian run vaccination site in the country.
