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.

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

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.

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

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