Michigan ranks second in U.K. variant cases behind Florida. Epidemiologist Dr. Rick Sadler said the vaccine is playing a vital role. “I think the appetite is shrinking for imposing more restrictions,” Sadler said. “It is a race against time as the U.K. variant grips the state of Michigan. It’s both more contagious and potentially more deadly. There’s not a ton of data on it yet, but that could be very concerning.”
