Happy Birthday, Vaccinations!

On this day in 1796 Edward Jenner performed the world's first successful vaccination, innoculating (as shown in this painting by Robert Thom) a young boy with cowpox to protect him from the scourge of smallpox - 25% of adults and 30% of children who caught it died, over 60 million in the 18th century alone.
