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

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

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.

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

The disease is eradicable. We have good vaccine to eradicate the disease (and) all countries are committed.
