It occurs to me that I didn't mention PReP for HIV, which is obviously effective in what it does. I do tend to think of the direct risk in a PReP context as more severe, and also PReP requires active management of a physician's care, so it is a bit different than the thing being discussed, but it's also a counterexample to my point and so in charity I decided to add it in this reply.
