"The vaccine was tested in Thailand against types of HIV that circulate in Thailand," Kim says, pointing out that a different strain of the virus causes high infection rates in Africa...
...significant period of time" before the trial results lead to a vaccine that can be submitted for approval for use in the general public, if such a breakthrough occurs at all. Most licensed vaccines have an efficacy rate of at least 70%, although it's possible that an HIV vaccine with lower efficacy may gain approval, Kim says.
