Thank you for that answer. We have now vaccinated a greater share of our population than any other country with more than 1 million people, and that extraordinary success means that Wales might be able to start vaccinating children, pending the evidence and advice that you have just mentioned. But leading the world means that we can't follow by example, and extending the vaccine to children will be a new challenge. One of those challenges will be that other people will make those decisions for those children, and that, of course, is right. Parents and guardians will decide whether they receive it or whether they don't. So, what is the Welsh Government doing to prepare for that new challenge as we enter the next crucial stage of the vaccine roll-out?
