Well, Llywydd, thank you to Siân Gwenllian for those supplementary questions. It's great to hear that her mother has received her vaccination, and I've been reading over the weekend about everything that's been happening in Arfon and on the Llŷn peninsula. I will refer in a moment to something I saw from Dr Eilir Hughes, who's been leading the vaccination efforts on the Llŷn peninsula. But, in terms of the ICT systems, things are happening so quickly and the NHS Wales Informatics Service are trying to resolve these problems that have arisen. They are happening because everyone is doing their level best to do everything they can to provide vaccinations to people the length and breadth of Wales. Areas of north Wales have led on those endeavours, so I can tell Siân Gwenllian that we're aware of the problems, and people are working very hard to resolve them. I do want to refer to one of the sentences I heard from Dr Eilir Hughes at the end of the weekend. It is in English, so will I just quote it in the original, because it does demonstrate the spirit and the effort that people are making.
