That is very helpful. However, if we take outdoor dining and outdoor events, certainly from a business perspective, as one of the options, then there must be a lead-in time. There must be some heads-up given to those businesses so they can prepare. I know Dr. Glynn will accept that, if it can be factored in.

If I can I want to expand on the matter of any modelling NPHET may have done on the vaccine roll-out and the relationship between it and our ability to ease restrictions. What milestones must be reached in the vaccine roll-out to allow us to significantly ease restrictions? I ask because in the letter Dr. Glynn sent to the Minister on 29 March, he said the vaccine roll-out gives real hope that there can be a much more widespread easing of measures during the summer months. "Widespread" is obviously significant. Therefore, in Dr. Glynn's view what milestones or staging posts in the vaccination roll-out must be reached to allow NPHET to make more decisions about easing restrictions?
