Jenner is granted another twenty thousand pounds for his continuing work in microbiology in 1806.
His continuing work on vaccination had prevented his continuing his ordinary medical practice.
He has been supported by his colleagues and the King in petitioning Parliament and had earlier been granted ten thousand pounds for his work on vaccination.
Edward Jenner had continued his research on the smallpox vaccine 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 twenty-three cases.
Some of his conclusions are correct, some erroneous; modern microbiological and microscopic methods will make his studies easier to reproduce.
The medical establishment, cautious then as now, deliberates at length over his findings before accepting them.
Eventually, vaccination is accepted, and in 1840 the British government will ban variolation—the use of smallpox—and provide vaccination—using cowpox—free of charge.
The success of his discovery had 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 is successful, and Jenner writes, "I don’t imagine the annals of history furnish an example of philanthropy so noble, so extensive as this."
Jenner had become 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 is elected a foreign member of the Royal Swedish Academy of Sciences.
