The worst potential bio-terrorist is nature itself.

When I was a child, there were not that many vaccines. I was vaccinated for polio. I actually got measles as a child. I got pertussis, whooping cough. I remember that very well.

I run a modest-sized laboratory thats looking specifically at what we call the pathogenic mechanisms of HIV disease, or AIDS.

We can sharply deflect the curve of HIV incidence.

The world is a place that is so interconnected that what happens in another part of the world will impact us.

An AIDS-free generation would mean that virtually no child is born with HIV; that, as those children grow up, their risk of becoming infected is far lower than it is today; and that those who become infected can access treatment to help prevent them from developing AIDS and from passing the virus on to others.

The bodys immune system is like any other system of the body. Each of them have their vital function for the human host.
