My guess is that Covid vaccination will be like Hep B, 3 shots and done. Hep B is given at 0, 1 and 6 months and then it is good for years. Alternatively, 2 shots with 4-5 months apart should be also pretty decent protection, specially if the person was already infected. We shall see.
I made a prediction 3 weeks ago, I was using the Brits as model. My bad, forgot to apply the stupidity multiplier for Americans. Still, depending on which website's numbers we believe, the average daily death is around 775 (not adjusted for FL), not that much higher than my 600ish top guess, although it could still go higher. Florida seems to be peaking in cases a few days ago, a week later than my expectation. We shall see if there is going to be a quick drop off like in the UK, probably not because of the schools starting. The downslope of cases/death should be more gradual.

I think these numbers still need a FL (+200 daily) adjustment. They report their numbers in bulk per week, last 7 days was 1423 or something.
