I know I'm aware of it. I believe that both Australia and the U.K. have identified mefloquine quite positively as a significant risk factor for neuropsychiatric disorders.
I would tend to agree that the research is in its infancy, as I said. Clearly more needs to be done, but I think if we listen to the veterans and the stories that they're telling us, what we learn is that there is this very significant reaction. It's not simply exposure to mefloquine, and perhaps that's the confounding variable here. If you only look at whether the veteran was exposed, then that might wash out in the statistics. If you look at the veterans who have developed that reaction, the initial reaction to taking the mefloquine, that's going to predict the longer term impact. Perhaps that's the piece that has been confusing here.
