...but there are a LOT of variables that impact the mechanism of infection and have to be considered before this study gets a stamp of approval.
We know that uncircumcised men contract HIV at a greater rate than circumcised men. If this study was conducted in an area where Judeo-Christian beliefs are mostly absent, that could influence the results.
We know that an unifected woman has a one-hundred times greater likelihood of being infected by an HIV positive male than an unifected male has of being infected by an HIV positive female - the ratio of men to women in the study could sway the results.
Different cultures engage in different sexual activities and that could affect the results. (That's what I believe she was alluding to.)
Since HIV is a retro-virus, the length of the study would definitely impact the efficacy of the medication over the long term.
All in all, we have a LONGGGGGG way to go before people should start celebrating and letting their guard down.
