Based on the high infectivity rate and fast turnover of Ebola Zaire, I
wonder if the immune system could mount an adequate defense even if
antibodies were present from a vaccine.  You'd need a huge titer of
antibodies to combat the huge number of viral particles.  Plus the window
between infection and detection is only a few days, and then detection to
death isn't much faster.  Containment and avoidance have been the best
defenses so far.
