It's not a completely wild idea, but it's unlikely to work. We had a
disucssion about this some time ago. To summarize that argument, there
is no guarantee that it will work, and because of the problems in finding
a valid experimental system, it's not testable yet. I also remember
reading somewhere (sorry, my mind is melting in the heat and I can't
remember where) that there is some suggestion that Ebola (like Dengue)
has antibody-mediated enhancement of infection and so Reston accination
might actually make things worse. Again, without a good experimental
system thsi is all guesswork; and the risks of a bad guess are terrible.
