Ireland has been stricter than most yet they are opening up on 19th July. If the UK restrictions continue beyond that it would be outrageous.
I would still not count the relaxation of restrictions here in Ireland as being cast in stone - it is entirely dependent upon the public health situation at that time.
The focus in Ireland right now is on trying to accelerate the vaccine rollout, and in particular trying to maximise the numbers who have received both shots (or have received the single shot Janssen vaccine). The 30-39 age group are due to be invited to register for their first shot by next Monday. As of last week 57% of the adult population in Ireland have received one dose, and 26% are fully vaccinated, but the latter figure should significantly increase over the next month.
Let's be honest, the key to getting out of this is maximising the vaccine rollout, and getting a significant majority of the adult population in each country fully vaccinated.
In the meantime, Ireland has tightened restrictions on unvaccinated people arriving from GB since yesterday. They now must self-isolate for 14 days upon arrival here.
