We could have learnt from those two episodes. But, do you know what? We actually had a third run as well, because the flu vaccine 2019 also ran short of supply. Another infectious disease—our third one in the hands of this Government, all in this Government, our third opportunity to learn and do better; we didn't know that coronavirus was coming. Our third opportunity to do better, and what happened? We ran out of flu vaccines again—the third infectious disease. It also showed us how poor our modelling store was, now 18 months later. It also created perverse behaviours and incentives, some of which I'm not very happy with, which we also saw during coronavirus.
