Rt Hon JACINDA ARDERN: That is absolutely right. Of course, other countries have sought to purchase vaccines to cover their entire populations, and in some cases have found that with the reasonably short shelf life of this vaccine, most countries have about four months to have them distributed across their population, and have not been able to use their supply necessarily across their whole population. That's where you've, only in recent times, seen those kinds of arrangements, and that is, really, captured by the fact that New Zealand was the first country to use the EU template agreement for the purchase and supply of vaccines within the EU, because we had not had that template arrangement available to other countries prior to that point.
