The idea of the live-virus vaccine is to produce in a continuous way some viral antigens.

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

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

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

That is why it is so important not only to have excellent treatment but also to try to get back the immune defense, because there you have a natural defense that takes place everywhere.

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.
