After the eradicating program success only two stain of small pox keep for research and preparing vaccination in the future incase if the disease reemerge again. The two remaining stain was kept by two major power in the world during coldwar which are the SOVIET and US.
The one in US was keep safe in the laboratory untill today and waiting time to be use. But after the cold war we know that the soviet union going down and collaps. The stain keep by the soviet went missing and no one know wehre it is today.
