Coronavirus vaccine

Things are looking up. I marvel that, exactly one year and three days after I last taught students in a university classroom, I will receive my first dose of the coronavirus vaccine. Over 90 million people have now received at least one dose, and the full powers of the government have been deployed to broaden and hasten the logistics around delivery. As I write, there are three different vaccines available which have significantly ramped production capacities in the last month or so.
