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.

One of the by-products of being a perfectionist and constantly trying to improve myself are sobering feelings of low-grade anxiety and a nagging sense of inadequacy This anxiety keeps me humble.

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 believe in striving for excellence. I sweat the big and small stuff! I do not apologize for this.
