19 June

Prediction is a mug's game. But here's mine, for the end of the Covid-19 pandemic. We won't beat it with a vaccine or treatment. It'll just stop. Like every pandemic in history, the microbes suddenly pack up and go home. And it'll be almost overnight, taking everybody by surprise. History is a much better guide than medicine here. (As to why microbes just pack up and go home, that's another topic - fascinating too.)
