Thanks, Peter, and I suspect you're not Robinson Crusoe with these questions. So I'll spend a bit of time on it. I mean, firstly, on contracting, very happy. Based on what we can see, we will retain market leadership. We're on track to be a blockbuster. We can cover ACIP a little bit later on. But yes, I think we're very happy with the work that's been done by the team on the ground there. In terms of vaccines in China, Look, I mean, I think at a macro level, we're extremely happy with the partnership we've started with [indiscernible]. This is a strategic partnership. This is a long-term partnership. The start-up process for Shingrix has been completed in Q1. We have reps on the ground as of the end of May. And if you just look at numbers, they've already expanded from 6,000 points of vaccination that we were covering. They've already hit 19,000 and are on track for around 27,000 by the end of the year. So scale of that company and the impact that they can bring to -- for Shingrix in China is clear. Now in terms of broader vaccine demand, we did see some softness in servers, but it's confounded by the fact that we moved resources off the product as well. We do hear some signs that some of the local CDC do have tighter budgets. And this is something we're going to watch very, very closely. But for us, the key here is that Shingrix is at a very different point in the life cycle to HPV vaccines. We're just getting started here. So we've got the best possible partner. We'll build the opportunity. If you look at the opportunity, it's very similar to the U.S. When you look at people in China that can pay out of pocket and that are in key cities. So the numbers are very large, but we need to build that. We've just shipped the 60% of the remaining will ship the rest of the order. In the second half, we did have a delay of shipment, not demand-based. -- but we just booked another £94 million in July. So we're on track to fill the full contract for the year. So that's China. If we get on to the U.S. and Shingrix growth I mean basically for the full year in Shingrix, we're not going to grow versus last year, but the second half, obviously, is going to be stronger than the first half. If I just expand on the 3 factors. And the first 2, let me be really clear, these are half 1 dynamics. So we've moved through them. The first one is wholesaler, as I said in my earlier comments, that delta is about 300,000 doses. So we finished quarter 4 '23 with 700,000 in the wholesaler and that's typically what we like. As I've said on previous calls, in Q2, it went down to around 400,000. So that was -- that's something though that we expect to be rebuilt as we go into the flu season. The second factor was CMS rule changes covering direct and indirect remuneration on DIR fees. And just as background, these are basically discounts pharmacies pay Medicare PBMs and plans spotters certain quality measures are not met. And the complication has been historically the PBMs can request these retroactively for up to 6 months from the point of sale. So that's obviously a complication for the pharmacy and the pharmacy group. The new rule that was brought in remove retroactive -- the retroactive part. So basically, at the point of sale, all of these components had to be booked and visible. And what that meant was for the 6 months, so from January to June, there was just less incentives for [indiscernible] to vaccinate patients. And we saw them shifting volumes between different types of vaccines to offset that. We've now moved into the second half of the year. We look at market research, tracking, et cetera. TRx trends adjusting for 4th of July is looking very encouraging. The key thing also, this is very much a pharmacy structural element that has expired. If we look at market research for physicians, and their enthusiasm to recommend Shingrix either strongly or extremely strongly. If you're looking at 65 plus, it's 88%. So that's the same as last year. 60 to 64 is 80%. So again, same as last year, 50% to 59% is around 50%. So that's all where it was. If we look at patient engagement, that's also holding overall, but that leads to the third factor, and this is something I've mentioned on previous calls. As we penetrate this population. And if you look at the rate that we've penetrated with Shingrix, is double the rate of PCV. So we've got there in 7 years, what it took PCV vaccine to get there [indiscernible]. But as I said before, the most motivated people obviously sort out the vaccine, and we've been able to penetrate those populations to a very high degree. In our #1 segment, we're around 66% penetration. So we have to work harder to get less engaged people, less motivated people. There is a huge plan to do that. So we will be looking at patients which are resident in other specialties, we're looking at COVID, we're looking at comorbid ways that we can stop leakage some account management work that we're doing as well. And then we're just really changing our marketing mix to focus on segments who [indiscernible] to activate. So that's the plan. And if you put all this together, basically, we'll expect some growth in half 2. But again, we're at this evolution of really looking outside the U.S. to Europe, Japan, Australia and China for our growth. And then ultimately, once we've moved through those cohorts, we'll get to emerging markets as we've covered on previous calls. Long story short, we can never get this and we remain confident that we could hit our £4 billion target with Shingrix in 2026. So a long answer, but hopefully, that is helpful to everyone else.
