Another interesting field, which is my own, is cofactors, not only to the disease but also to transmission. I am still puzzled by the fact that you get more sexual transmission in some ethnic populations. One way to answer this is to look for genetic factors.

It's easier to learn things for life by the age of 12 and not the age of 18. This is just my guess.

Basic research is very useful, but it should be more geared toward application than it was before.

Since most of the transmission is sexual transmission, you have a regional or local response to the virus.

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.

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.

I've participated in meetings where there were concerns by ethical experts. There is no clear solution.
