"I think those are the sorts of things you can do. I would be hesitant to walk into a big crowd where you know large portions of people haven't been vaccinated yet, without a mask on," he said.

"I'd wait until we really get a lot of people vaccinated before I stop wearing a mask when I go out," said Rutherford.
