I didn't get the impression that this was a permanent side-effect. Just like any disease, it would eventually be phased out of the body. The movie only showed Spike seeing butterflies in the first place (and he only sees one at movie's end), and no one else says a word about seeing anything, IIRC.
Vincent had been exposed to the antidote long ago. He saw tons of the butterflies. This suggests that the antidote takes a very long time to dissipate and that it leaves you in very bad shape by the time it does.
Remember that the head military / intelligence goon thought Victor was a threat because he had the nanotech antidote in his blood. He could not have cared less about Victor using nanotech weapons to slaughter everyone, just as long as all possibility of an antidote was "erased".
