It's clear that prevention will never be sufficient. That's why we need a vaccine that will be safe.
Our goal is not to completely eradicate the infection - that would be very difficult - but to produce a vaccine that will prevent not infection but disease. I think this is more possible.
My proposal now is to test a vaccine first on people who have been infected, and if you show some efficacy at this level, you might be able to go further to study uninfected people in a population with a high rate of infection.
The idea of the live-virus vaccine is to produce in a continuous way some viral antigens.
Since most of the transmission is sexual transmission, you have a regional or local response to the virus.
