That's not a response. The multiple simultaneous sexual partners are relevant to the fact that prevalence of the disease in Africa is very high. This is not a vaccine-related question, so the action of the vaccine can't speak to it.

> I would just suggest that stating that an entire continent of different races/culture/religions "having multiple simultaneous partners" smells just a little bit of "savages over there"

Funny, if you look at my comment, you should see that it refers to "the much higher prevalence" of this behavior in Africa.
