The basic difference between the two islands is that those governing one of them looked to protect their people; the other took steps to preserve their economy (which is ironic given that the UK economy has taken one of the biggest hits during the Covid19 period); one government cared about people; the other couldn't give a flying one about them. It's reflected in fatality rates:
UK deaths from Covid19 - 1,749 per million
Ireland deaths from Covid19 - 798 per million
Yes, the NHS are doing a great roll out job. But that's a necessary cleaning up of a mess of calamitous proportions.
All true, but you to try to look at it from the UK eyes out. Everyone knew that the Uk economy would be hit by Brexit and it was heading into likely its most challenging period economically in its very recent history anyway. Then Covid hit. i wouldnt be a fan of brexit, Johnson or the government. But i can see very real dangers to the UKs welfare both economically because of Brexit and from a public health point of view with Covid. Its a tricky balancing act for the politicians of juggling public health and the economy - both things broadly impact on the wellbeing of Uk citizens. Do i think the UK has done either well, not really, but it has been a horrible perfect storm for the UK and the UK has considerations other countries dealing with this dont.
I do think the above explains some of the logic of the Uks decisions, the initial herd immunity, struggle with PPE, the eat out to help out stuff, the reluctance to go into lock down in the second wave, then did it to late, you cant protect one aspect without hurting the other and really didnt get either right and UK citizens have suffered holistically in terms of health, economically and subsequently from a whole holistic wellbeing point of view.
I don't agree with the UK current approach, it might be fine, but its a feeling your way in the dark strategy with no evidence really to back it up. It might be grand, but i dont think if the UK hadnt had such a bad time in terms of public health or their were not real fears economically, they would be making different decisions on this. They are desperate to get the vaccines out there and i dont blame them. Granted much of Europe is way behind, they dont seem to be making the same desperate decisions. I think they are making them because of a desperate position both on public health and economically and to be fair the county has had a really, really hard time during this in every way - so from that point of view if you can accept that is there position i can understand the logic of decisions, even if i dont agree with them. Perhaps everywhere else has the benefit of being patient and risk adverse - like not rolling out AZ for over 55s for example.
Lets hope it works out though, whatever happens in Ireland will affect the Uk and vice versa, we have seen this with both Brexit and the Uk variant, so we have to hope for both Islands the whole thing works out.
