Llywydd, I thank Hefin David for that follow-up question, and he's absolutely right about what has been achieved in Caerphilly—over 7,000 people over the age of 80 already vaccinated in the borough. Somebody is vaccinated every five seconds here in Wales, so I'm quite certain, by the time this question is over, somebody in Caerphilly will have been vaccinated as part of that programme, and I think it tells us something, Llywydd, that we're now at that stage in the programme where we are able to focus on not just the huge infrastructure effort that has been made in securing all the mass vaccination centres, the over 400 GPs participating, the mobile units that are out there vaccinating as well, but we're able now to focus on the practical detail of the sort that Hefin David has highlighted this afternoon. Of course, we don't want to see elderly people, particularly, having to queue outside in the January and February weather, and making sure that there are transport opportunities for people who can't rely on their own cars when we ask them to go to a particular location to get vaccination, those are the sorts of details we're now able to grapple with. And in the work that is led by my colleague Vaughan Gething, and I join him every week in a meeting with the top team responsible for vaccination across Wales, we will make sure that we take up the issues that the Member has raised today so that we can assist the efforts of Caerphilly County Borough Council in making sure that the programme goes on being the outstanding success it is today.
