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

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.

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.

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.

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

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