I read everything downthread of this and am flummoxed at how much people are talking past each other. If the UK has 40k deaths, the only way the UK is close to herd immunity is if the IFR 0.05%. People can quibble about how many actual cases there are, but no matter how you slice it, reinforcing the parent poster, we are a long way from herd immunity. Also, remember that if you want to argue the IFR down, that means you're arguing the R0 up, which makes herd immunity more difficult.
