Is Cow Pox Vaccination a Good Thing?

People who lived and worked on dairy farms had cow pox after that experience were immune to the smallpox virus. So Edward Jenner started following this line of research. He began to ask what if we were to inject different forms of the cow pox virus into perfectly healthy people but who don't live and work around cows? And maybe they too could become immune, he thought. But there was a huge backlash in Western European culture against Jenner called the anti-vaccine society. It's because it's very hard to understand this idea. You need to get very sick so that you can be healthy with a cow disease for all of a while.
