I don't think a vaccine will be the end of it. I think people will just become so desensitised to Covid (alot of us already have) that we'll pretty much just go back to normal and the media/government will stop talking about the deaths.
I mean, we're already largely back to normal. Just with masks on (that really isn't a big deal you pussies) and with people standing a bit further apart from normal.
The peak was only 2-3 months ago and half the population have already lost all fear. Give it another 3 months and zero fucks will be given.
