What Dr. Bernstein and I have both commented on is that there was really a sea change with the results from the Thai trial. I can tell you our principal focus right now is on following up on that Thai trial, on those very exciting results from last summer, and following up in a way that can accelerate a similar trial being conducted in Africa with vaccines that are appropriate for the sub-types of the vaccine that are present in Africa, without at the same time losing sight of keeping alive, in parallel to that, other vaccine concepts in case that doesn't work.
