James Phipps (1788 – 25 April 1853) was the first person given the cowpox vaccine by Edward Jenner. Jenner knew of a local belief that dairy workers who had contracted a relatively mild infection called cowpox were immune to smallpox. 
Life and vaccination against smallpox
On 14 May 1796 he was selected by Jenner, who took "a healthy boy, about eight years old for the purpose of inoculation for the Cow Pox". Jenner took some fluid from the cowpox vesicles on the hand of a milkmaid named Sarah Nelmes (in an unpublished manuscript Jenner refers to her as Lucy Nelmes), and inoculated Phipps by two small cuts in the skin of the boy's arm.
Jenner wrote: On the seventh day he complained of uneasiness in the axilla and on the ninth he became a little chilly, lost his appetite, and had a slight headache. During the whole of this day he was perceptibly indisposed, and spent the night with some degree of restlessness, but on the day following he was perfectly well.
On 1 July 1796, Jenner took material from a smallpox pustule and inoculated Phipp's arms with it. The boy survived, and Jenner concluded that he now had complete protection against smallpox. Phipps was subsequently inoculated with smallpox more than twenty times without succumbing to the disease.
Later in Phipps' life, Jenner gave him, his wife and his two children a free lease on a cottage in Berkeley, which went on to house the Edward Jenner Museum between 1968 and 1982. Phipps attended Jenner's funeral on 3 February 1823.
Phipps is often cited incorrectly as the first person to be vaccinated against smallpox by inoculation with cowpox: other people had undergone the procedure before him. In 1791, Peter Plett from Kiel in the Duchy of Holstein (now Germany) inoculated three children and Benjamin Jesty performed the procedure on three family members in 1774.
