That's a committee similar to this one, I believe.
What they're trying to bring out is the issue of long-term effects. Do we have any evidence from soldiers or others that the type of neuropsychiatric effects or other types continue after the drug is stopped? That's the critical point there.
The evidence that it continues for a long time after the drug is stopped.... What we have is what seem to be some very rare cases. All the attempts to show it in the studies have failed to show it. There are reports that it may have happened, but they're individual reports, so it's hard to see whether it's more common in the people who took mefloquine than it is in people who took any other drug.
We have a hypothesis that it might be a very rare event. The question then is whether, in that setting, it outweighs the benefits of the drug. The benefits are clear—preventing malaria is paramount.
