Investigating rare diseases gives researchers more clues about how the healthy immune system functions.

The launch of phase 1 Ebola vaccine studies is a first step in developing a vaccine that could be licensed and used in the field to protect not only the front line health care workers but also those living in areas where Ebola virus exists.

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.

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

You can have an epidemic in a state. You can have it in a region. You can have it in a country where the critical level of disease passes a certain threshold and we call that an epidemic threshold.
