I teach professional mariners who travel from all parts of the country. They test before they launch on their journey( kinda useless) and then we are all together in a classroom for 6 hours a day. We follow all the protocols- mask up etc, and no issues so far. I probably could get myself bumped up, but I will wait my turn. I am healthy/no underlying conditions. The way things are looking, it will probably be another month or so. I would rather get the J&J single shot anyway.
