These are relatively complicated policy discussions that we've had among G7 countries, and now among DAC countries, as part of the OECD, with COVAX. We've tried to provide the best estimate of an average cost. We're not privy to the specific cost paid per dose by COVAX, but we're trying to find a fair representation that would appropriately reflect, in a transparent way, the cost of procurement of the doses that COVAX has done.
