DENVER (KDVR) — Colorado Gov. Jared Polis shared new information about adjustment’s to the states vaccine distribution plan.

During an afternoon news conference, 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.

So far, nearly 70% of people over the age of 70 have been vaccinated. They, along with moderate risk healthcare workers, make up Phase 1B.1.

Additionally, vaccinations are being given out to people in Phase 1B.2, which covers educators, people between the ages of 65-69, and those who are involved in the continuity of state government.

People who don’t fall in any of the Phase 1B groups will be part of Phase 2, which will be the general public. Gov. Polis said there might be age-based mini phases, but that won’t be determined until we approach that phase. This is expected to begin in late April or early May.
