Everyone is worried about Delta. But based on data from the UK, it won’t last long. It’s super efficient at infecting, but it burns through the match too fast as there aren’t a lot of people left to infect.
Here’s daily cases from the UK. Their vax rate is a bit higher than the US, but they also used a vaccine that isn’t quite as good as Pfizer/Moderna. Importantly note they didn’t put in really any restrictions so this is natural burn out this time.
It was about 6 weeks from bottom to top. I’m not sure about the exact time frame, but my guess is we have peak delta cases in 3-5 weeks and then we head back down again.
