I take it the Irish roll out is much slower than the UK is because they agreed to go along with the EU idea of all doing it together! They have then been slower to order and slower to approve the vaccines. Which means the UK is on a head to head basis well ahead of the curve compared to the EU. We have been lucky in a way. We approved Astra-Zeneca for the over 60s before the data proved the efficacy in the over 60s. We took the word of the scientists at face value when they said there was no reason to doubt it's effectiveness in the elderly! And that gamble seems to have paid off as initial results both in Scotland and England seem to suggest that its effectiveness is even higher than Pfizer's high effectiveness. Could have gone the other way I suppose.
