I doubt it. The Soviets manufactured a stockpile of 20 tons of smallpox virus. I doubt Iraq is the only country that may have obtained samples of this weaponized virus. Also human nature hasn't changed. What is really needed is more research into both new and safer vaccines (by orders of magnitude) and treatments for viral diseases like smallpox. It is quite likely in the future that a bioterrorist would use a pathogen for which there is no exiting vaccine. The ability to treat viral diseases with generic treatments analogously to the way we treat bacterial infections (with antibiotics) would help to alleviate the threat of bioterrorism.
I agree. We have some drugs to treat viral infections, but for the most part, if you have a virus, it's "sink or swim"
