What have you been reading?
I'm dumbfounded that anyone would be under such an impression.
Perhaps you are mixing it up with weaponizing it.
I'm having a hard time following you here...(?) I thought it was clear that I was refering to the difficulty of weaponizing smallpox. Also, the material I read, which may have been dated (about 10 years old, if memory serves), mentioned the ability to contain smallpox in the context of the technology/methodology already available that was used to eradicate it.
