Thank you for that. It's a big challenge, as we go forward, with regard to that whole aspect: Do I walk around with an immunity passport to show that I've been immunized? You know as well as I do that not everybody who's exposed to an agent necessarily develops an antibody to it. Does that now become an issue that we concern ourselves with, restricting people's freedoms?
