More than 70% of the eligible population in at least 12 Colorado counties have received at least one dose of coronavirus vaccine, state health officials said Wednesday night.

Tiny San Juan County in southwest Colorado, home to Silverton, has the highest rate of eligible people who have received at least one dose of COVID-19 vaccine at 89.1%. Denver’s rate as of Wednesday night was 70.1%.

“I’m thrilled to see that Colorado counties are making great strides towards reaching our vaccination goals to end the pandemic,” Gov. Jared Polis said in a written statement.

Sixteen counties have less than 40% of their eligible population vaccinated. At the bottom of the state’s list is Crowley County, east of Pueblo, where only 18.3% of eligible people have received at least one dose of coronavirus vaccine.

More than 3.1 million Coloradans have received at least one dose of COVID-19 vaccine. Roughly 2.7 million people in the state are fully vaccinated.
