Ep 12- Vaccines Eradicated SmallPox? Part 4

Part 4 of 5: Learn about how Edward Jenner's cow pox vaccine did nothing to stop the spread of small pox, but in fact was making things worse.

Jenner, the small pox vaccine inventor, had finally gotten a paper published, but had added a new element to his theory- cow pox doesn't actually prevent small pox, but a horse disease called the grease. The Royal Society knew the public wasn't going to accept the horse grease theory and asked him to remove all references to it.
