A couple things about this graph.
First, it’s quite apparent that Covid comes in predictable waves, about 3.5 months apart.
Second, the vaccines were available in Jan 2021. I’ll let you decide how helpful they were.
Third, Covid is clearly endemic now. We need to be all done with treating it any differently than the flu.
