There is a sense amongst some that it is simply a question of a recipe, and we know that not to be the case. These are biologics. They're highly complex. They have over 200 ingredients. There's a technical expertise that's required in their manufacturing, so this is one of the issues we have when we think about the waiver. You cannot reverse-engineer a biologic. You can't simply take the vaccine and say, “Well, I know how this was made”, and replicate that easily. In fact, it would be next to impossible.
It is absolutely true, as you point out, that there is a serious problem around the production of vaccines. We need an enormous number of vaccines, and we have to ramp up the production as quickly as possible. It's not clear that the waiver is the way that will be done, but I say “not clear”. We do not have an opinion, necessarily, but we're examining that.
