The feds' post-attack vaccination plan makes perfect sense. It makes sense for responding to an anthrax attack, though -- not a smallpox attack. Smallpox is a stalking horse for anthrax. Can't talk about anthrax too much -- people would connect the dots.
Ergo, we prepare for anthrax while talking about smallpox.
Amusingly, the CDC director gave the game away the other day, with a slip of the tongue in an interview with PBS. See GETTING READY.
Your post is very interesting. I think you have something there worth serious thinking.
