A bit shit is an understatement, Northern Ireland is being looked at, and I'll
be interested to see the outcome, but Von de Leyen's antics have not exactly helped the EU stance. The rest of your post are simply societal issues that everyone is, and will be facing, but as of now, leaving the EU is proving to be a decision, even if solely focussing on this one aspect of vaccines, and as posted above, there are others, to be the best thing we've done.
Dispute this if you like, I'm sure you and others will, but it's an absolute
fact that you're better off here, and out of it.
