How easy is it to develop a biological weapon?
Developing an effective anthrax strain is challenging since the spores have to be crafted to just the right size. If too small, a person will exhale the spores. If too large, the spores fall to the ground and become, as Olson says, “road kill.” Developing a smallpox agent is also difficult because the virus cannot be easily grown as a seed culture and it is so deadly that lab workers trying to culture the virus could easily become infected and die.
