Dr Fauci says...
"If you combine getting most of the people in the country vaccinated with getting the level of virus in the community very, very low, then I believe you are going to be able to say you know for the most part we don’t necessarily have to wear masks," Fauci said. "When it goes way down, and the overwhelming majority of the people in the population are vaccinated, then I would feel comfortable in saying you know we need to pull back on the masks, we don’t need to have masks."
I’m trying to follow the science described by our leading scientist. Can someone please tell me what these scientific terms mean???
