Yes. It's actually about a delay to the doses in terms of the batch testing. So, we think there's going to be a delay to supply in Wales, as opposed to an entire loss, and it's an issue that affects the UK as well. So, I have another meeting with the vaccines Minister, Nadhim Zahawi, this week, from the UK Government. I have another meeting with Cabinet health Minister colleagues from across the UK this week as well. So, we are continuing to talk with each other about vaccine supply issues and delivery, and there isn't, as I understand it, a particular issue that I can give more detail on in the way that the Member asks, other than I hope to give what is a helpful reassurance about the fact the four nations are working together, and the delay to our supply is something we expect to be made up so that, of course, our hard-working, fantastic NHS staff and colleagues can get on with delivering the vaccine programme to help protect people right across the country.
