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.

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.

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.

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.

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.

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

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