With all due respect Winter, I wouldn't want to be in a crowd of people if some of them aren't vaccinated, for whatever reason. I actively stay away from busy or crowded places. If someone can't get the vaccine for health reasons they have to ask themselves do they possibly want to carry the virus and possibly infect a lot of people.
Being able to prove you aren't positive for Covid before gaining entry to the football, a gig or anywhere else crowded might be the only way to keep us all safe. If I wasn't able to have the vaccine and had underlying health conditions then I wouldn't be going to a highly infectious place like a football ground.
I don't have the answers but Governments do and we could easily end up locked down again.
