When someone gets the first dose of the vaccine, they will be given the date for the second dose—that is part of the planning. One complication of the Pfizer vaccine, although we expect that it is not peculiar to it, is that it requires two doses rather than one. In the fullness of time, that might change. The health secretary and I had helpful discussions late yesterday afternoon with the senior management of Pfizer, at which we discussed supply and what they might hope for in terms of development of the vaccine in the longer term. However, what we have right now is very welcome, and we are working hard to overcome any of the logistical challenges that are associated with its characteristics.
The first people have been vaccinated already today, and we will publish figures over the course of the coming days and weeks as the programme develops.
