Covid is flatlining in the UK, and nobody is really sure why. It’s not vaccines, though they’re likely a major contributor. Not enough people are vaccinated there to explain the dramatic drop in cases. It could be school holidays, but again nobody is sure. The other possibility, which I mentioned last year, is that the virus may eventually get to a point where it just gives up. We talk only about immunity (ourselves), and not about virulence (the virus’ own agency).
