The issue then becomes how to go about doing that. Up until now, it's all been pretty easy because Pfizer has made an application under the Medicines Act to the New Zealand Government, consent has been given, and we go forward from there. The conundrum that has arisen now is that Pfizer has not made any application for a fourth dose, and—I just might note in passing—that is pretty frustrating, to be honest. I understand Pfizer's point of view is that they won't make any application in any country. And, of course, other countries are going through the process of providing a fourth dose notwithstanding the fact that Pfizer hasn't necessarily applied in those countries, because of course all those countries have their own legislative schema and their own legislative requirements, which differ from country to country.
