Rt Hon JACINDA ARDERN: Look, over the past couple of weeks even, I've had conversations with leaders in other countries that, like us, have entered into advance purchase arrangements. We do not yet, as nations, have exact clarity on delivery dates for vaccines. Some—in fact, the vast majority—are still in clinical trials. So that's the first thing. The second issue is that each country will take their own perspective, or at least sequencing, around the regulatory approvals. Some countries, because they are experiencing a large-scale loss of life, may choose to accept higher risk in their regulatory process. Thirdly, there will not necessarily be the same delivery date for all countries, and I do, again, just reference the fact that some countries are experiencing large-scale loss of life.
