There is an average of 7708 deaths in the USA every day.If everyone who wants a vaccine has one by the end of May, and it's not enough of the population to reduce community spread and cases, so we're still at 500 or more people dying every day. Then, yes, I don't expect people to go back to normal. Some will, but not everyone, and I don't think the majority will.
We could drop everything and open it all back up, since anyone who wants a vaccine could get one, but all it would do is drive that number up. If there's still 500 or more people dying every day because of large spread, I expect those open things might have a little bump, but it's not going to be the masses trying to go out. They'll still have some self preservation.
There will be some that treat the vaccine as a super power. That use it's protection against death as a reason to not care about being exposed. These people are a danger to everyone, including themselves. They'll drive up the virus/vaccine interactions and increase the likelihood of a variant the vaccine doesn't protect against. These are the same people that demand antibiotics at the first sniffle and have lead to resistant bacteria. They're the reason hospitals put strict controls on some antibiotics.
Conversely, if we have enough vaccinated people that causes cases to go low enough. Nothing will be able to contain people, and there wouldn't be any reason to either. I don't want to restrict anyone if there's no reason to.
That's the point. We can produce and distribute vaccine as much as we want. If enough people don't actually take it to cause spread to go down, it's not going to do us any good. Opening up needs cases down, spread controlled. It doesn't care about any one person getting vaccinated.
We can debate the number here. Maybe I'm wrong, and more people are totally fine with 500 a day/180,000 a year. My number for back to normal is under 150 daily, and I already feel like a monster that it's not lower. Google tells me we're still around 2,000 daily, so there's a way to go just to get to 500 still.
So, same sales pitch as before: Help the community, get vaccinated, bonus, you get to not die. But, it's not a superpower that you should throw caution to the wind about exposures.
