Serious question about coronavirus endgame
As I understand it there are three ways that this epidemic can end: (1) herd immunity through mass vaccination; (2) herd immunity through mass infection [e.g., .us]; (3) elimination through isolation [e.g., .kr].
It seems that different countries are going to arrive at different endpoints. What then? Must we prevent travel from a 2-country to a 3-country for years?
