I think we all know it's entirely possible that there'll never be a vaccine. Long term it's possible it will mutate into something less deadly but no guarantees of anything.
I was watching a programme last night and they were saying how there isn't much wiggle room with R, so it's just a trade off. If we want to go back to work/school, have shops open, we won't be able to see family.
When I go out now it's clear that a lot of people have just given up. Lots of large groups congregating, teenagers playing out together. I know of several people/neighbours who are visiting family. I worry that we are just going to see another huge spike in cases.
