Joanne and, I believe, Roger spoke to that earlier, so I will just add my comments as well.
While CanSino was very much part of what was talked about, it was kind of early on and later on. Any discussions we had were done in parallel. All the other vaccine candidates that we looked at were considered at the same time. None of the decisions around CanSino impacted the timing of any other decisions. It wasn't waiting for one to get to the other.
At least from the time the vaccine task force was put in place, we looked at all those things from the beginning when we met. We looked at all the potential candidates, domestic candidates and international candidates, starting at that time, and again, as we said, we looked at them in parallel, not sequentially.
