The hon. Lady is right to emphasise that point. We all hope that low-income countries will become middle-income countries and graduate from being supported by Gavi. In 2015 and 2016, for which we have the most recent data, countries that graduated from the Gavi programme maintained the levels of vaccination, but this needs to inform the next period in terms of replenishment, because we cannot afford to lose the community benefit of the level of vaccination.
I was deeply moved by the speech of my right hon. Friend the Member for North East Bedfordshire (Alistair Burt), who I enjoyed having as a colleague for so many months, and I pay tribute to the work he did to champion this cause. I hope his father is still watching television—hello, Mr Burt.
