Rt Hon JACINDA ARDERN: Demand. We have more than enough supply. Supply will no longer be an issue for the course of this vaccine roll-out. We have long signalled—long signalled—that October was the month when supply no longer becomes an issue, and with the additional doses that we managed to secure from Spain and Denmark, that certainly made that the case from September. One thing I'll also point out is we do expect, of course, those numbers to move again once that big cohort we saw come through early on in the outbreak return for second doses. In fact, today was the first day where second doses outnumbered first doses. Pleasingly, the uptake for second doses is at a very high rate, so we do anticipate being able to mirror that high first rate uptake with second. But it is going to take all of us. That last, kind of, 10 percent is going to be the bit that every country has seen takes that extra bit of effort.
