I'd point out that we're not the only country in this situation. Australia, since they encountered some resistance to the roll-out of the AstraZeneca vaccine, have been working very hard to secure additional supplies of the Pfizer vaccine and they were no more successful than New Zealand has been up until this point. So things have changed a lot over the last month, which have opened up new possibilities for New Zealand and Australia. We've taken a different approach to the Australians in the way we talk about that. We tend to talk about it right at the end once the deal's been done and the vaccines are on the way; they tend to talk about it while they're negotiating the deals. Those are decisions for our respective countries. But I can assure every member of the House that the goal of getting vaccines into the country as fast as possible has been driving Government activity since the beginning of the year.
