If you are saying a pandemic ending vaccine will be here in a matter of months, with all due respect, you do not know that. That is a highly speculative and rosy prediction. From everything I've read, that is very unlikely to end up being true.
They do have a solution, you just don't think its a good one. Remove the restrictions, and everyone evaluates the risks for themselves. Whether you know it or not, we all do that to some degree every day regarding Covid. Even wearing a mask is a risk - if you truly wanted to eliminate risk, you'd never be in a place where it was necessary to wear a mask. So, it's all a matter of degree.
