Rt Hon JACINDA ARDERN: The first thing I'd say is that, actually, per capita, we are beating them on peak doses at the moment by quite some margin with the delivery that we are going through. The second point I would make is that they still have restrictions in place, because they still have outbreaks despite having started their vaccine roll-out sooner. I would also point out we have lower case rates, lower death rates, lower levels of restrictions. All of that, for me, is a measure of success, a measure of success in whether or not your relative strategy for COVID, of which there is no costless response—whether or not you've adopted the right strategy for your country. On vaccination programmes, so those countries, of course, they all have multiple vaccines. We decided to deliver Pfizer, and in some cases they used emergency approvals rather than going through a full approval process, as we did.
