The scientist who entered [Room 3C16] saw 12 mysterious cardboard boxes on a crowded shelf in the far left corner of the storage space and pried one open to see what it contained. Inside, dozens of long vials were packed in rolls of white cotton and sealed with melted glass; many of the labels were worn to the point of illegibility. The scientist noticed one vessel that held some loose, freeze-dried material. Its label bore a single decipherable word: “variola,” another word for smallpox.

If that occurs, he says, the world needs to be ready with the safest, most efficient vaccine possible.
