As delta variant surges in Yellowstone County, care facilities ramp up vaccination push Elder care facilites in Montana continue COVID vaccination push amid delta variant surge and last updated 2021-08-04 19:53:46-04 BILLINGS- On Wednesday, the Yellowstone County Unified Health Command released new numbers showing a rise in COVID-19 cases due to the delta variant. Leadership at St. Johnâs United retirement community in Billings says theyâve changed little in the months since the pandemic peaked, still implementing the same safety procedures they have for months to protect guests. While retirement communities across the nation have moved to mandate employee vaccinations, facilities in Montana are handcuffed from doing the same by a new law approved during the last legislative session. They have one real tool: urging people to choose vaccination, and it's working for residents at St. John's.
