I think there's almost no chance that by some point in the summer (the earlier the better) it won't be the case that every single person in the country that is of the approved age (is it 18-65? 85? 16? not sure on that one) will have had the opportunity to get their dose or doses. The only people who won't have had it are the ones that don't want to get it or are worried about allergy, etc.
The J&J is big because it's a single dose. It's not as highly effective ... but that shouldn't matter for most regular, non-elederly, non-high risk, types of folks. Those people likely weren't going to even need to be hospitalized in the first place, and with their one dose hopefully will only have mild symptoms at worst.
The more highly effective two dose versions can then be saved for elderly and high risk. And if we don't use up all our shots by then, fine. Sell/give them to other countries. The whole world will need it.
We're already seeing very nice progress, with less than 10% of the country having had one or more doses.
This looks like we're be back to Sept/Oct levels by April? Something like that.
So, until it appears otherwise, I'm 100% in on full stadium capacity and tailgating. I can't friggin' wait.
Oh, also: State Fair too!!!
