Thanks very much. Well, we are talking about trying to get this booster to 1.6 million eligible people in Wales. That's being delivered through 400 vaccination sites, so I think that does give you the coverage that should allow people to take up that opportunity. As I say, our target is to get to a 75 per cent uptake of that cohort, and so far we're on track. So, we're getting to it. I'm slightly concerned that we're not getting the response from health and care workers that I had hoped we'd get, so I would encourage people to try and encourage those health and care workers in particular to take up that opportunity, in addition, of course, to vulnerable people, and to come forward if it's offered. I know that, in Clwyd South, for example, 34 per cent of the people eligible have already had their vaccinations.
