I answered this question on another thread. What you should be interested in (as I am) are any positive results that come from this very small, and VERY early, trial of a vaccine against recurrence of the virus that Leslie mentions. The trial is closed. Now we wait to find out the results. You have to remember that understanding of it all, and the final commercialization of any vaccine that might result from it, is YEARS down the road, and millions of dollars in investments.
