Hi..
here is your answer. .
● The 1st vaccine was produced by Edward jenner in 1796.
●He made an attempt to provide protection against smallpox.
●Jenner noticed that milkmaids who had contracted cowpox , seemed to be resistant.
●From this fact he concluded that the human reaction to an injection of cowpox viruses would somehow reach the human body to respond to both viruses without causing major illness
hope it helps you. ☺

Smallpox vaccine, the first successful vaccine to be developed, was introduced by Edward Jenner in 1796. He followed up his observation that milkmaids who had previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox.
By 1768, English physician John Fewster had realised that prior infection with cowpox rendered a person immune to smallpox.In the years following 1770, at least five investigators in England and Germany (Sevel, Jensen, Jesty 1774, Rendell, Plett 1791) successfully tested in humans a cowpox vaccine against smallpox.For example, Dorset farmer Benjamin Jestysuccessfully vaccinated and presumably induced immunity with cowpox in his wife and two children during a smallpox epidemic in 1774, but it was not until Jenner's work that the procedure became widely understood. Jenner may have been aware of Jesty's procedures and success.A similar observation had also been made in France by Jacques Antoine Rabaut-Pommierin 1780.
Noting the common observation that milkmaids were generally immune to smallpox, Jenner postulated that the pus in the blisters that milkmaids received from cowpox (a disease similar to smallpox, but much less virulent) protected them from smallpox.
Dr Jenner performing his first vaccination on James Phipps, a boy of age 8. 14 May 1796
On 14 May 1796, Jenner tested his hypothesis by inoculating James Phipps, an eight-year-old boy who was the son of Jenner's gardener. He scraped pus from cowpox blisters on the hands of Sarah Nelmes, a milkmaid who had caught cowpox from a cow called Blossom,whose hide now hangs on the wall of the St George's medical school library (now in Tooting). Phipps was the 17th case described in Jenner's first paper on vaccination.
Jenner inoculated Phipps in both arms that day, subsequently producing in Phipps a fever and some uneasiness, but no full-blown infection. Later, he injected Phipps with variolous material, the routine method of immunization at that time. No disease followed. The boy was later challenged with variolous material and again showed no sign of infection.
Donald Hopkins has written, "Jenner's unique contribution was not that he inoculated a few persons with cowpox, but that he then proved [by subsequent challenges] that they were immune to smallpox. Moreover, he demonstrated that the protective cowpox pus could be effectively inoculated from person to person, not just directly from cattle.Jenner successfully tested his hypothesis on 23 additional subjects.
