For the past five decades my wife and I have enjoyed attending live performances of theater and dance companies, in crowds ranging in size from 25 to 2500. Sitting with strangers elbow-to-elbow, close behind, close in front, hearing people talk, laugh, sneeze, cough, standing up to let late-comers get to their seats, as they brush by inches away. Standing in close-packed, long lines for restrooms during intermission. Jam-packed lobby as people leave. How good would we have to believe a vaccine to be, for us to be comfortable spending a few hours that way?
