In case anyone wants a taste of what Delta can do when let loose on large swaths of unvaccinated people:
We opened up entirely just at the point Delta was gaining traction, with <5% of young people vaccinated, which lead to superspread events that every expert warned about but our government refused to listen to. A rowing club tried to give a party of 400 people with mandated testing beforehand...and now they're looking at 230+ cases. The primary reason we're not growing more now, is that we have reached testing capacity limits already.
Delta will flare up in communities of unvaccinated. It's no longer a choice of 'vaccine or not', it's a choice of 'vaccine or gnarly/deadly Covid', and I am saddened that too many will realize that fact too late. But at the same time, vaccine willingness is now at 94% over here, so I am hopeful that we can get out of this to some degree this fall. It's gonna be a bumpy ride, but we know vaccines work, we know lockdowns work. Helplessness has been replaced with reluctance to act, which is less bad.
