A passing mention in the middle of the article caught my eye: > a total of “15 questionable vials” with five labeled as “smallpox” and 10 as “vaccinia.” Had I misremembered the etymology of “vaccine”? Was this a typo? Turns out to be an interesting story (https://en.wikipedia.org/wiki/Vaccinia); https://en.wikipedia.org/wiki/Vaccinia); TLDR, the actual origins of the smallpox vaccine are surprisingly murky (due to a lack of early record-keeping), so when scientists discovered that the virus they were using to make it was actually a separate, otherwise unknown species they used the name that Jenner had originally applied to the cowpox he used for his early vaccinations.
