It might be possible to reintroduce Smallpox and I guess that idiots who also think coal is a good idea might actually be stupid enough to make it happen. But, fortunately humans did wipe out one other disease and unlike Smallpox it wasn't deemed useful as a biological weapon so AFAIK nobody kept copies, it's just gone.

Funnily enough, RFK Jr. is doing what he can to bring its human cousin back:
"Measles virus evolved from the then-widespread rinderpest virus most probably between the 11th and 12th centuries."
Good thing that smallpox wasn’t eradicated due to a vaccine.
Vaccinia is very different from Smallpox. Or perhaps I misunderstand you?
That was sarcasm, right?
