 What about the cost of this? I mean, I don't know how many people you want to see getting this treatment. There's presumably some kind of issue with targeting it, but also antiretrovirals are typically quite expensive. So, you know, is this going to be affordable? That's the critical thing. I have no doubt it's cost effective. Whether it is going to be affordable is really the biggest question of all. And we're waiting to see what the originator, what the farmer does to date.
