I haven't seen any government documents claiming that it was effective for inhalation anthrax in humans. They do note (rightly) that there seems to be excellent protection in primates.
As for safety, the bulk of the research I've read suggests that the vaccine is safe for most people in most instances. I think the site I directed you to earlier provides pretty good documentation of established risks. Again, if we go by what the studies have shown in controlled environments, the vaccine has a pretty good safety profile.

Please review the the facts straight out of the Citizens Petition and the Declaratory Judgement lawsuit. The facts are they've broken the law.
You can find them at the sites I listed. Over and out!
