Edward Jenner Timeline
(May 17, 1749 – January 26, 1823)Edward Jenner (1749–1823) was an English physician and scientist known as the father of immunology. His development of the smallpox vaccine in 1796, using cowpox material to confer immunity, marked the birth of vaccination and laid the foundation for modern preventive medicine, ultimately leading to the global eradication of smallpox in 1980.

Smallpox Vaccine
Variolation imported to Britain
1721
Lady Mary Wortley Montagu had imported variolation to Britain after having observed it in Constantinople, introducing an early method of smallpox immunization to England decades before Jenner's work.

Daniel Bernoulli analyzes smallpox data
1766
In 1766, Daniel Bernoulli analyzed smallpox morbidity and mortality data to demonstrate the efficacy of inoculation.
John Fewster realizes cowpox confers immunity
1768
By 1768, the English physician John Fewster had realised that prior infection with cowpox rendered a person immune to smallpox, a key observation preceding Jenner's vaccine.
Benjamin Jesty vaccinates his family with cowpox
1774
The Dorset farmer Benjamin Jesty successfully vaccinated with cowpox and presumably induced immunity in his wife and two children during the 1774 smallpox epidemic, though it was not until Jenner's work that the procedure became widely understood.
Rabaut-Pommier makes similar observations in France
1780
In 1780, Jacques Antoine Rabaut-Pommier made similar observations in France regarding the protective effect of cowpox against smallpox.
First vaccination of James Phipps
May 14, 1796
On 14 May 1796, Jenner tested his hypothesis that cowpox could protect against smallpox by inoculating James Phipps, the eight-year-old son of Jenner's gardener — the world's first vaccination.
Phipps re-inoculated with variolous material
Jul 1, 1796
On 1 July 1796, Jenner injected Phipps with variolous material, the routine method of immunisation at that time, and again no disease followed, demonstrating the protective effect of cowpox.
Publication of Inquiry into the Variolae vaccinae
1798
In 1798, Jenner used the term 'vaccination' in the title of his Inquiry into the Variolae vaccinae known as the Cow Pox, in which he described the protective effect of cowpox against smallpox.
A Continuation of Facts and Observations published
1800
In 1800, Jenner published A Continuation of Facts and Observations relative to the Variolæ Vaccinæ, a 40-page work further documenting the success of his vaccine.
President of the Jennerian Society
1803
In 1803, Jenner became president of the Jennerian Society in London, concerned with promoting vaccination to eradicate smallpox. The society ceased operations in 1809.
Key Facts
- Edward Jenner was born on May 17, 1749, in Berkeley, Gloucestershire, England.
- In 1796, Jenner tested his hypothesis that cowpox infection protected against smallpox by inoculating eight-year-old James Phipps with cowpox material.
- He published his findings in 1798 in 'An Inquiry into the Causes and Effects of the Variolae Vaccinae,' coining the term 'vaccine' from the Latin word for cow (vacca).
- Jenner's work established the practice of vaccination, which became the basis for modern immunology; he is often called the 'Father of Immunology.'
- His vaccination method led to the worldwide eradication of smallpox, officially declared by the World Health Organization in 1980.
