As far as I'm aware, if OAS does become an issue, there's little or nothing we can do about it. Another round of vaccines won't help, even if 'tweaked' for a new variant.
And another round of lockdowns or restrictions won't help either, but no soubt some people will try and bounce the government into implementing some measures.
The most that might happen is measures similiar to what happened in Sweden, but things would have to be really bad for that to happen.
The economy and people's mental health just can't take any more.
This is what happened in the late 1940s, when people grew tired of post war austerity, even if they originally accepted it was necessary.
