Thank you for that series of questions, which I'll try to address as quickly as time allows.

You're correct; my understanding is that officials were informed on 2 September, and I was informed with a serious incident alert on 3 September. That's entirely normal. Public Health Wales had already informed the Information Commissioner, as they should do, of the breach. They had identified what had happened, and as I say, we don't believe that anyone has come to harm, but it is a serious breach and it needs to be treated seriously. That's why there is an independent investigation. That investigation will be taken through the board accountability and governance processes, so you can expect there to be a published report into that investigation once it's been received. And as you know, the chief executive of Public Health Wales issued a proactive press release and gave a series of interviews yesterday setting out what had happened, and indeed apologising for the serious breach. There is no attempt to cover over the fact that this was a serious breach that took place, and it was reported as a serious incident, as indeed all serious incidents are between the health service and the Government.

In terms of addressing waiting lists, I'm afraid I don't share the Member's optimism about the ability to significantly eat into waiting lists over the winter period. It's a reality in every nation of the UK that the significant increase in activity that has built up during the first period of lockdown, where we both ended NHS services—. You'll recall that on 13 March I was the first UK health Minister to make the decision to pause most forms of elective activity. We've seen a significant build-up as a result of that, and then, even as services have restarted, there's been some reluctance from members of the public to access services that are now available. In common with every other Minister in every one of the four nations, I'd say that most of the next term, a full Senedd term, will be likely to be needed to catch up with the activity we're seeing, partly because of the activity that's built up, but also because we're not able to see people in the numbers we'd otherwise do. That's about the need to screen people, between COVID secure and those where they are suspected or COVID-positive. It's also the reality that our staff can't undertake as many procedures with the additional PPE requirements. So, it isn't realistic for us to expect there to be a significant eating into waiting lists through this period of time. It will need prioritisation for people with the greatest need, and that means that it's going to be difficult because some people will need to wait longer. But, as I said, that is not a situation unique to Wales. You may have seen the commentary from the King's Fund and others about the scale of challenge that we're going to face right across our national health service, and we'll talk more and more about the reasons for that, including our staff. And I was pleased to hear you mention our staff, because our staff haven't really had a break, across our health and social care system, since the start of the pandemic, and that gives me great concern about not just the potential for a second wave, but the longer term future. 

We have introduced more support—occupational health support, health and well-being support—and I have had very regular conversations with representatives from employers and trade unions. There's been even more conversation between those parts of the workplace relationship than even we would have had in normal times. That's because what our staff have had to do will have an impact on them, for more support, practically, to keep them in the workplace, but we also know that there is an effect that takes some time to manifest itself when people have been through particularly difficult or traumatic events. So, through the next term, we'll need to deal with the reality that staff in health and social care will need more support, and some staff will need to come out of the workplace to recover and some staff may leave prematurely.

So, actually we have had a really big challenge building up with more activity that we can't undertake now and we'll face a challenge in our staff. But I can say, though, on the positive side: you mentioned challenges around PPE to support staff; we're in a much better position than at the start of the pandemic, where we found that we had stores that we had in use, and once we'd used the pandemic stores, our normal plans would have been to have contracts in place, but other countries then didn't honour them because they had their own challenges and, as we've rehearsed many times, the world market in PPE tightened significantly. We've rebuilt and stocked up our stores, we've been very successful within the family of UK nations in doing so, and we've helped other UK nations through mutual aid with PPE requirements. We've also managed to continue to supply PPE to our social care sector as well. So, we have a much better situation on stock than the position that I faced when going through the pandemic in April and May of this year. 

On the flu vaccine, the UK Government procure for all four nations. That's an agreed process. So, we're optimistic that we'll have more flu vaccine in place for every UK nation, including, of course, Wales. We're looking to prioritise the most vulnerable. There's a section in the winter protection plan on what we're looking to do to both have a higher rate of uptake in our most vulnerable populations and if we still have enough vaccine to then go out and have people over the age of 50 receiving the flu vaccine as well, as well as our in-any-event plan to have more pre-school and primary school-age children undertaking and receiving the vaccine as well. 

On dentistry, we expect more data to be provided in the NHS operational framework that I mentioned. This has been a real challenge because, of course, dentistry is a high-risk profession—it's pretty impossible to undertake socially distanced dentistry work, there's the proximity you often need to be able to do the work and, indeed, the aerosol-generating procedures. We can expect there to be more detail through the operational framework and the advice from our chief dental officer.
