The immune systems goal is to protect the body against invaders either from without, such as microbes, or from within, such as cancers and different types of neoplastic transformation.

Staph lives on skin. Thats the reason why many infections start as a boil.

What has happened over the years is that scientists have now developed AIDS therapeutic capabilities, as well as prevention, and we've linked prevention and treatment in a way that if you fast-forward 30 years form '88 to now, we can say without hyperbole that we have the tools, if implemented the way they could be implemented, to theoretically, essentially end the epidemic as we know it now.

Although it is still important to develop an HIV vaccine, we have significant tools already at our disposal that can make a major impact on the trajectory of this epidemic.

The worst potential bio-terrorist is nature itself.

There cannot be any impediment to science that will ultimately be good to the general public.

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.
