DENVER (KDVR) — Gov. Jared Polis gave an update to Colorado’s COVID-19 response and vaccine rollout from the Governor’s Mansion Tuesday afternoon.

As of February 28, 70.7% of Coloradans aged 70 and up have been vaccinated, hitting Colorado’s goal of vaccinating 70% of that population by the end of February.

Colorado is expecting 45,500 doses of the newly authorized Johnson & Johnson single-shot vaccine by the end of the week. Governor Polis says Colorado is not expecting to receive any J&J doses next week, but that supply will dramatically increase in the weeks after.

With more options for vaccines available, Governor Polis says there should be vaccine transparency and visibility so people know which shot they’re receiving when they sign up for appointments.

“All three vaccines, highly effective, safe, save lives, all of them are almost 100% effective in preventing death from COVID-19,” Polis said.

The governor went on to say because of an uptick in Pfizer and Moderna shipments, plus the added option of J&J doses, Colorado could vaccinate roughly twice as many people per day by the end of April compared to the end of February.

Late last week, the governor announced a change to the next phases of vaccine distribution, and timing for eligibility.

Polis announced that Phase 1B.3 has been split and will begin March 5. It now only includes people over age 60, people with two or more health factors and workers in frontline grocery and agriculture positions. This is expected to be about 1 million people

The new Phase 1B.4 is expected to begin on or around March 21. As currently structured, it will include people over age 50, people with high risk conditions and frontline workers in the following fields: higher education, restaurants and food service, essential manufacturing, the United States Postal Service, faith leaders, public health workers, human service workers, and essential journalists. This is expected to be about 2.5 million people.
