Yes. I'm afraid that I don't actually know the overall cost of that, but one thing that's important to note is that one of the issues that makes this affordable now is in terms of the patent on the two drugs that are actually used for PrEP. One of them was already available as a generic formulation, but the patent on tenofovir actually ran out a year and a half ago.
Now, we're actually able to use generic antiretroviral medications not just for PrEP but also for HIV treatment. The costs of these medications have dropped dramatically. It really makes PrEP a much more financially feasible program now.
