MINNEAPOLIS (AP) — Minnesota health officials are turning buses into mobile COVID-19 vaccine units that will focus on serving communities with a high rate of the coronavirus.

The buses are staffed to provide up to 150 vaccinations per day and are available to community groups that want to host events to deliver shots.

The state Health Department said vulnerable areas include agricultural workplaces, homeless encampments and housing complexes where residents lack transportation. Targeted communities include people of color, urban Native Americans and people with disabilities, the Star Tribune reported.

“Folks who live in high social vulnerability index communities have had a very disproportionate impact from COVID-19,” state Health Commissioner Jan Malcolm said Tuesday at a news conference. “So, this idea of these mobile buses is the next piece of our strategy to get the vaccine into the communities where it is so critically needed.”

The retrofitted Metro Transit buses include space for two patients to wait for shots, while two others receive them, said Nicole Nee, a clinician with Blue Cross and Blue Shield of Minnesota. Two buses are being used this week, and the state plans to add four more in coming months.

Health officials on Tuesday reported 1,189 new COVID-19 cases and five more deaths due to complications from the coronavirus.
