 Yeah, no, I think Jonas was always heartbroken when that trial was done because he knew that there would be children who would intentionally not be given the vaccine. I mean, the one thing is to say, as you roll out a vaccine, like the Ebola vaccine, when it rolled out into West Africa, not everybody got it at once. And so some people got it, some people didn't, and some of the people who didn't get it obviously weren't saved. But it's different than when you actually purposefully don't give a vaccine for a period of a year.
