Edward Anthony Jenner (17 May 1749 – 26 January 1823) was an English physician and scientist from Berkeley, Gloucestershire, who was the pioneer of smallpox vaccine. He is often called "the father of immunology", and his work is said to have "saved more lives than the work of any other man".
 Early life
Edward Jenner was born on 17 May 1749 (6 May Old Style) in Berkeley, as the eighth of nine children. His father was the vicar of Berkeley, so Jenner received a strong basic education. Jenner trained from the age of 13 for eight years in Chipping Sodbury, South Gloucestershire, as an apprentice to Daniel Ludlow, a surgeon . In 1770 Jenner became apprenticed in surgery and anatomy under surgeon John Hunter and others at St George's Hospital.
William Osler records that Hunter gave Jenner William Harvey's advice, very famous in medical circles (and characteristic of the Age of Enlightenment), "Don't think; try." Hunter remained in correspondence with Jenner over natural history and proposed him for the Royal Society. Returning to his native countryside by 1773, Jenner became a successful family doctor and surgeon, practicing on dedicated premises at Berkeley.
Jenner and others formed the Fleece Medical Society or Gloucestershire Medical Society, so called because it met in the parlor of the Fleece Inn, Rodborough, in Rodborough, Gloucestershire, meeting to dine together and read papers on medical subjects. Jenner contributed papers on angina pectoris, ophthalmia, and cardiac valvular disease and commented on cowpox. He also belonged to a similar society that met in Alveston, near Bristol.
 Natural history, science and marriage
Jenner was elected Fellow of the Royal Society in 1788, following his publication of a careful study of the previously-misunderstood life of the nested cuckoo that combined observation, experiment, and dissection.
His description of the newly-hatched cuckoo, pushing its host's eggs and fledgling chicks out of the nest (contrary to existing belief that the adult cuckoo did it) was only confirmed in the 20th century,  when photography became available. Having observed this behaviour, Jenner demonstrated an anatomical adaptation for it—the baby cuckoo has a depression in its back, not present after twelve days of life, that enables it to cup eggs and other chicks. The adult does not remain long enough in the area to perform this task. Jenner's findings were published in Philosophical Transactions of the Royal Society in 1788.
"The singularity of its shape is well adapted to these purposes; for, different from other newly-hatched birds, its back from the scapula downwards is very broad, with a considerable depression in the middle. This depression seems formed by nature for the design of giving a more secure lodgement to the egg of the Hedge-sparrow, or its young one, when the young Cuckoo is employed in removing either of them from the nest. When it is about twelve days old, this cavity is quite filled up, and then the back assumes the shape of nestling birds in general. " (Letter to Hunter at the Royal Society, as above.)
Jenner's nephew assisted in the study.
Jenner married Catherine Kingscote (died 1815 from tuberculosis) in March 1788 after meeting her while he and other Fellows were experimenting with balloons. Jenner's trial balloon descended into Kingscote Park, Gloucestershire, owned by Anthony Kingscote, one of whose daughters was Catherine.
Jenner is also credited with advancing understanding of angina pectoris. In his correspondence with Heberden, he wrote, "How much the heart must suffer from the coronary arteries not being able to perform their functions."

Inoculation was already a standard practice but involved serious risks. In 1721 Lady Mary Wortley Montagu had imported variolation to Britain after having observed it in Istanbul, where her husband was the British ambassador. Soon, Voltaire recorded that 60% of the population caught smallpox and 20% of the population died of it.
In the years following 1770, at least six investigators in England and Germany (Sevel, Jensen, Jesty 1774, Rendell, Plett 1791) successfully tested a cowpox vaccine in humans against smallpox. For example, Dorset farmer Benjamin Jesty successfully 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 some twenty years later that the procedure became widely understood. Indeed, Jenner may have been aware of Jesty's procedures and success.
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. He may already have heard of Benjamin Jesty's success.
On 14 May 1796, Jenner tested his hypothesis by inoculating James Phipps, a boy eight years old (the son of Jenner's gardener), with pus scraped from the 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.
Ronald 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. In addition Jenner successfully tested his hypothesis on 23 additional subjects.
Jenner continued his research and reported it to the Royal Society, which did not publish the initial paper. After revisions and further investigations, he published his findings on the 23 cases. Some of his conclusions were correct, some erroneous; modern microbiological and microscopic methods would make his studies easier to reproduce. The medical establishment, cautious then as now, deliberated at length over his findings before accepting them. Eventually, vaccination was accepted, and in 1840 the British government banned variolation – the use of smallpox – and provided vaccination – using cowpox – free of charge. (See Vaccination acts). The success of his discovery soon spread around Europe and for example was used en masse in the Spanish Balmis Expedition, a three year long mission to the Americas, Philippines, Macao, China, and Saint Helena Island led by Dr. Francisco Javier de Balmis with the aim of giving thousands the smallpox vaccine. The expedition was successful, and Jenner wrote, "I don’t imagine the annals of history furnish an example of philanthropy so noble, so extensive as this.”
Jenner's continuing work on vaccination prevented his continuing his ordinary medical practice. He was supported by his colleagues and the King in petitioning Parliament and was granted £10,000 for his work on vaccination. In 1806 he was granted another £20,000 for his continuing work in microbiology.
In 1803 in London he became involved with the Jennerian Institution, a society concerned with promoting vaccination to eradicate smallpox. In 1808, with government aid, this society became the National Vaccine Establishment. Jenner became a member of the Medical and Chirurgical Society on its founding in 1805 and presented a number of papers there. The society is now the Royal Society of Medicine. In 1806, Jenner was elected a foreign member of the Royal Swedish Academy of Sciences.
Returning to London in 1811, Jenner observed a significant number of cases of smallpox after vaccination. He found that in these cases the severity of the illness was notably diminished by previous vaccination. In 1821 he was appointed Physician Extraordinary to King George IV, a great national honour, and was also made Mayor of Berkeley and Justice of the Peace. He continued to investigate natural history and in 1823, the last year of his life, he presented his Observations on the Migration of Birds to the Royal Society.
Jenner was found in a state of apoplexy on 25 January 1823, with his right side paralysed. He never fully recovered and eventually died of an apparent stroke, his second, on 26 January 1823, aged 73. He was survived by one son and one daughter, his elder son having died of tuberculosis at the age of 21.
 The Rev Dr John Clinch - The first community vaccinator
In a letter to Jenner in Gloucestershire dated December 1, 1796, Dr. John Clinch, a medical missionary at Trinity, then the second largest settlement in Newfoundland, asked for further information about using cowpox pustule matter as a vaccination against smallpox. Jenner had vaccinated his first subject only six months earlier. By June 1800, when Jenner published his famous pamphlet, "An Inquiry into the Causes and Effects of the Variolae Vaccinae," describing his vaccination experiments on 23 subjects, Clinch probably had been vaccinating people in Newfoundland for a year or more.
Jenner and Clinch, both born in 1749, had been classmates at Reverend Dr. Washbourn’s school in Cirencester, Gloucestershire, before they went to London together to be pupils of John Hunter. Jenner returned to his home area, but Clinch practised three years in Dorset near Poole, the main shipping port for Newfoundland. In 1775 Clinch moved to Newfoundland to practice in Bonavista. After eight years, he moved to Trinity, where he also preached Anglican sermons on Sundays. Jenner’s nephew, George Jenner, seeking a similar church–medicine career, very likely began his medical apprenticeship under Clinch at Trinity in 1789.
On July 15, 1800, a second shipment of vaccine from Edward Jenner reached Clinch; one of these, most likely the first, came via George Jenner, by then the Anglican minister at Harbour Grace on the intervening peninsula between Trinity and St. John’s. By the first week of October 1800, Clinch had vaccinated additional people in the adjacent settlements of St. John’s and Portugal Cove and by the end of 1801 had vaccinated 700 people.
William R. LeFanu’s definitive bibliography of Jenner credits Clinch with being the first vaccinator in North America, before Benjamin Waterhouse, who vaccinated his own sons in July 1800 and then popularized vaccination in Boston. Sadly, exact dates for Clinch’s first vaccinations are unavailable. Clinch is honoured by a memorial plaque in Trinity. (This section reproduced from John W.R. McIntyre, MB BS; C. Stuart Houston, MD 'Smallpox and its Control in Canada'. CMAJ 14th Dec 1999)
In 1979, the World Health Organization declared smallpox an eradicated disease. This was the result of coordinated public health efforts by many people, but vaccination was an essential component. And although the disease was declared eradicated, some pus samples still remain in laboratories in Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia in the United States and State Research Center of Virology and Biotechnology VECTOR in Koltsovo, Novosibirsk Oblast, Russia.
An illustrated history of smallpox eradication, Smallpox Zero, was published with the support of Sanofi Pasteur and distributed on May 17, 2010, in Geneva during an event sponsored by the World Health Organization. Smallpox Zero includes President Thomas Jefferson's letter of congratulations to Edward Jenner.
