Staff at nursing home of coronavirus outbreak receive vaccine 03:27 Kirkland, Washington (CNN)In an instant, nursing director Chelsey Earnest can recall the worst day at work she has ever had.

The sirens seemed to blare endlessly outside the Life Care Center in Kirkland, Washington. "That was the night (we had) like five ambulances in the parking lot," she said. It was the night she sent patients to the hospital whom she expected would be treated and eventually released. They never came back.
