Denver plans community-based vaccine rollout as opposed to mass vaccination site vaccine and last updated 2021-01-14 16:39:17-05 DENVER â City health officials plan to carry out a community-based vaccination plan in the coming weeks, a model Denver found success with when ramping up COVID-19 testing last year. The plan is line with what state health officials showed a preference to this week â more locations of smaller vaccine clinics, as opposed to fewer large vaccination centers, such as Ball Arena in Denver. Bob McDonald, executive director of Denver Department of Public Health and Environment, said the city found more success in testing through smaller community clinics and expects vaccine rollout to be the same, with "dozens and dozens" of locations across the city expected to have the vaccine available.
