I was simply looking at yesterday and today, so I haven't looked as far as you. But they had more cases today than yesterday and the logarithmic chart is still increasing, but you're right that it isn't exponential anymore. That was my bad. My point is, if herd immunity is like flu herd immunity, then we have to have a new vaccine every year. And most corona viruses, the immunity is not long (SARS is an outlier as immunity seems to last for years). If heard immunity for corona viruses was such a great concept, we wouldn't be getting common colds over and over again every year.
