Phases 1A, 1B.1. 1B.2, 1B.3, and 1B.4 are all eligible according to the vaccine distribution plan. Phase 2 begins April 2, 2021.As we move through phases, people in previous phases remain eligible.In many cases, Coloradans who are not yet eligible to receive the vaccine can still sign up to receive alerts with some vaccine providers-- and should use the vaccine provider map or the list of providers once eligible. It’s important to know that vaccine providers may have varying amounts of vaccine during any given week. Vaccine providers are working as fast as they can to set up appointments for when they have the vaccine. Note that these locations are not open for walk-in appointments. They should be contacted directly for more information. Learn more about who is currently eligible to receive a vaccination by visiting our Vaccines for Coloradans webpage.
