Activism has been very productive in our society.

We feel confident that there won't be an outbreak. The people who were around the patient are now being identified and traced by the CDC and by the state health authorities. ... you get people, you identify them, and you observe and monitor them daily to determine if they develop symptoms If they do, then you put them under isolation to determine if, in fact, they are infected. And if you do that properly, you can shut down any outbreak.

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

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.

Testing two vaccines against different H1N1s at the same time has never been done.

Im generally considered a conservative in my predictions for disease.

You help someone's health, and you prevent them from infecting others.
