Who performed the first vaccination?
Edward Jenner, a young British physician was the first to vaccinate in 1798 with scrapings collected from cowpox blisters. He inoculated a healthy volunteer with cowpox material by scratching the person’s arms with a pox contaminated needle. The scratch turned into a raised bump. The volunteer became mildly sick within a few days and recovered, but never contracted either cowpox or smallpox.
