Ah. I misunderstood the function of PREP/assumed it was the treatment given to people who are already infected. I don't know why, because I feel like I've heard about PREP before. That does kind of muddy the waters a bit. I think it's better for everyone to have more treatment options, in this case, and a vaccine is certainly better, but ... deciding who has to take the hit in the risk department to develop one is odd. It still feels like it should be ethically possible. Logically, we don't want to pigeonhole ourselves into something of a "local minimum" when it comes to a viable solution to a problem, IE a situation where we have something that kind looks better than the surrounding avenues of research and the energy investment needed to find a lower-risk, higher-reward outcome is too high to be worth bothering.
