AIDS win be our first priority, but in two years' time we don't know where AIDS research will stand, so we are also thinking of activity on other diseases.

It's clear that prevention will never be sufficient. That's why we need a vaccine that will be safe.

The center will be fully operational in two years' time, but probably in the middle of the year we will have a temporary laboratory of 4,000 square feet.

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.

We don't know why, but there are some gradients of infection.
