I think that the issue is really.... Again, I can't speak specifically to the choice of what to give to soldiers in general, or a specific soldier, but the question is always whether the benefits outweigh the risks for a particular individual.
I can say that when we talk to particular individuals, there are many people who prefer mefloquine. It's easier. It's cheaper. They tolerate it well. They don't have effects. They take the drug, especially because it's a weekly drug versus a daily drug.
I'm sure that's something that has been mentioned at another time. The fact that it's weekly rather than daily encourages some people. It makes taking the drug much easier, and they're much more likely to actually take it. In some cases, that outweighs what we consider to be the very small risk of these kinds of complications. The risk of getting malaria so vastly outweighs the risk of these particular things you mentioned that giving people something they feel comfortable taking, and that they do take, is a very important concern when we're advising individuals.
