eli5 Why small pox inoculation is any different from catching it naturally?

806 viewsBiologyOther

So I’m having trouble with this, and I’ve went through different links on Google and can’t find an answer. So they would poke into sores of people who had smallpox and then proceed to cut the patient and insert the infection directly into them. I’m not understanding why catching small pox that way would be any different than catching it naturally?

I am specifically referring to how it was done during the revolutionary war, not today’s vaccines. But wouldn’t mind knowing how those two things differ as a bonus

Great responses, but I always love pointing out that Edward Jenner’s work with Cow Pox is what gave us the word “vaccination” from the Latin root Vacca meaning “cow”. Thus getting vaccinated is to be Medically Cowed.
