Smallpox has not re-emerged from an unrecognized human or animal reservoir, from a variolator
's store of infected scabs, or infected cadaver, either unearthed or thawed.
However, during the era of eradication, 45 scab specimens were collected from variolators
and tested 9 months after collection; live virus was not isolated from any of the specimens (35).
Jenner made his work freely available, which antagonised some variolators
who saw the loss of a lucrative monopoly.
