Colorado Coronavirus Vaccination Progress Update: April 21

More than 2.3 million Coloradans have received at least their first dose of the coronavirus vaccine, according to state data. More than 1.5 million Coloradans — around 26 percent of the state's population — are fully immunized.

More than 1,300 health care providers and clinics in Colorado are offering vaccines. Everyone who wants to be vaccinated should be able to receive their first appointment by the end of May, Gov. Jared Polis said.

The state's vaccination data dashboard shows which Colorado counties have the highest vaccination rates per 100,000 people:

Percent of residents vaccinated with at least one dose:

• Broomfield: 64.4 percent
• Boulder County: 60.8 percent
• Jefferson County: 59.6 percent
• Denver: 56.1 percent
• Douglas County: 54.7 percent
• Arapahoe County: 48.2 percent
• Adams County: 45 percent

Outside Denver's metro area, Eagle (68.1 percent) and Summit (66.9 percent) counties have some of the highest vaccination rates in the state.

Some counties have higher rates due to higher populations of people ages 60 and older, and front-line workers. And some eligible Coloradans are choosing to hold off on getting vaccinated.
