Yeah the story goes that a guy called Edward Jenner in 1796 created the first vaccine by taking a sample from one of his maids who had cowpox (Specifically a sample of pus from the blisters of a cowpox sufferer) and used it as the first vaccine against smallpox - the idea was that since they were both of a similar type of virus and those who got cowpox almost never got smallpox so deliberately causing the former would by default prevent the latter... although doing this overlooked pathogens spread by blood and it equally killed as many people as it was advocated that it could save.
