Update on April 2, 2021: When we launched this guide, Colorado’s vaccine eligibility plan was a maze of phases and subphases and sub-subphases. But as of today, it’s now a one-question quiz: Are you at least 16 years old? Click here if the answer is YES. Click here if the answer is NO. And best of luck as you search for your shot.

Back in those simpler days of … late last year, Colorado’s plan for rolling out the coronavirus vaccine seemed pretty clear: Phases 1, 2 and 3.


The latest from the coronavirus outbreak in Colorado:

  • MAP: Cases and deaths in Colorado.
  • TESTINGHere’s where to find a community testing site. The state is now encouraging anyone with symptoms to get tested.
  • VACCINE HOTLINE: Get up-to-date information.


But then Phase 1 became Phase 1a and 1b; and then Phase 1b was split with a mysterious dotted line; and now Phase 1b has been fully divided into sub-subphases 1b.1, 1b.2, 1b.3 and 1b.4.

Feeling lost amid all the parsing? We’ve put together a click-through guide to the state’s vaccine rollout plan. It is current as of April 2, 2021, which is when Colorado opened eligibility to anyone 16 and older . We’ll do our best to keep it updated when the state’s plan changes again, though please bear with us. Even for professional updaters, this has been tough to follow.

Congratulations! You are currently eligible to receive a coronavirus vaccine.

There are multiple ways to sign up for an appointment. The state’s COVID-19 website includes links to sign up for community vaccination sites and a county-by-county provider list. It also has a map that shows where vaccine shipments have been sent in the past two weeks, though a supplier’s availability will vary.

Prefer the older-fashioned way? The state has a 24-hour hotline to answer vaccine questions: 1-877-CO VAX CO (1-877-268-2926).

Other places to look for appointments include, which is run by the state. Appointments through the U.S. Federal Retail Pharmacy Program — which includes Safeway, Walmart and Kroger stores — are at

Individual hospitals and health systems also have their own sign-up procedures. The most effective way often involves creating an account in those health systems’ patient portals and then actively looking for available appointments. But hospitals and other health care providers, like Kaiser Permanente, also have sign-up forms where the provider will call you when there are appointments available.

You are age 15 or younger. Sorry, but there are no coronavirus vaccines yet proven safe or effective for you to receive.

This could change, though. At least two companies, Pfizer and Moderna, are testing their vaccines in children. So best to keep your eyes open for news. The state could add you to the priority structure if those vaccines are approved for kids.

The Colorado Department of Public Health and Environment has more information at Prefer the older-fashioned way? The state has a 24-hour hotline to answer vaccine questions: 1-877-CO VAX CO (1-877-268-2926).
