There is some concern that weaponized anthrax would be made resistent to penicillin. The infectious disease references that I have checked recommend either Ciproflaxin ($$$$$) or Doxycycline ($) for treatment of anthrax. Obviously, prevention is better than treatment, but I do not forsee mass anthrax immunizations. It is unlikely, in fact, for anthrax vaccine to be made available for use by the civillian community at all.<br><br>Jeffery S. Anderson, M.D.<br><br>
