That first vaccine used was the cowpox virus vaccine, that protected humans against the very similar smallpox virus. However even before Jenner introduced that vaccination, Asian physicians were using the main idea of vaccines by administering children with bacteria of the lesions of people who had the suffered from smallpox, to protect the children from obtaining the smallpox disease. However the Asian physicians basic vaccine idea did not work as well for them as they had planned it to, because as some of the children did become protected from the smallpox disease, many of the children sadly did become sick from smallpox. Jenners vaccine was much safer than simply just taken dried crusts from lesions of disease suffering people. Due to Jenner's safe vaccine contribution, he then opened doors for more vaccine work to be done. Louis Pasteur, a French microbiologist, injected preparation into sheep that contained forms of bacillus that caused the disease anthrax. By doing so, Pasteur displayed immunization against anthrax, and was then able to invent a vaccine suspension against rabies in 1885. Many years after Pasteur's development, vaccines against bacteria, viruses, venoms and as well as other toxins were discovered…
