We have actually more than one vaccine, so for information as it relates to our different vaccines and the differences between them, a lot of that is proprietary. It's proprietary information, but it's also very commercially sensitive. When we talk about Canada and the contract we have in Canada, it actually does impact. It could be seen as something that is of interest in other countries, because we also have these confidential contracts in other countries.
Again, I think we're talking about these contracts holistically, but there are definitely components that are commercially sensitive for us from a competitive perspective and proprietary for us, but that then also could impact or prejudice some of the discussions we're having right now as we speak with other countries around the world.
