Smallpox From The Past

An anonymous reader submits "Earlier this year, librarian Susanne Caro was looking through an 1888 book on United States Civil War medicine and discovered a small envelope labeled 'scabs from vaccination of W.B. Yarrington's children' and signed by Dr. W.D. Kelly, the author of the book. After a bit of research, she realized they might be smallpox scabs used in early live vaccination methods and contacted various officials including the Centers for Disease Control and Prevention. The CDC was excited by the find, because it gives them an untreated specimen from over a century ago, and a chance to look at the disease's evolution. Although the FBI had concerns that the smallpox may have been planted in the book, most of the researchers believe the scabs are too old to be dangerous, and they fear they may not even be able to yield live smallpox."
