The great advantage of the AstraZeneca vaccine is it's being made here in Australia. It will be available as soon as the TGA gives its tick, which we expect that it will in February. I just want to make the point, though, we're not the only country in the world that has AstraZeneca ordered. There are large orders, in fact you could see that AstraZeneca is one of the main-stays of the global response and remains so. The AstraZeneca vaccine is effective, it is safe, and it's a high-quality vaccine. But those are the things that the TGA will be looking at with their full approval coming very soon.
