“Having been among the early converts, in this part of the globe, to [the smallpox vaccine’s] efficiency, I took an early part in recommending it to my countrymen.”
Jefferson talks about his own smallpox inoculation, as well as John Adams’ experience. Jefferson admired Dr. Edward Jenner, the physician and scientist who was a pioneer of smallpox vaccination. Smallpox killed millions of people during Jefferson’s time, and continued to do so until the 20th century. The World Health Assembly declared smallpox eradicated in 1980.
Thomas Jefferson’s letter to Dr. Edward Jenner Monticello, May 14, 1806:
SIR,
-- I have received a copy of the evidence at large respecting the discovery of the vaccine inoculation which you have been pleased to send me, and for which I return you my thanks. Having been among the early converts, in this part of the globe, to its efficiency, I took an early part in recommending it to my countrymen. I avail myself of this occasion of rendering you a portion of the tribute of gratitude due to you from the whole human family. Medicine has never before produced any single improvement of such utility. Harvey's discovery of the circulation of the blood was a beautiful addition to our knowledge of the animal economy, but on a review of the practice of medicine before and since that epoch, I do not see any great amelioration which has been derived from that discovery. You have erased from the calendar of human afflictions one of its greatest. Yours is the comfortable reflection that mankind can never forget that you have lived. Future nations will know by history only that the loathsome small-pox has existed and by you has been extirpated.
Accept my fervent wishes for your health and happiness and assurances of the greatest respect and consideration.

Benjamin Rush was a physician, politician, social reformer, humanitarian, educator, and a signer of the U.S. Declaration of Independence. Rush was a leader of the American Enlightenment and an enthusiastic supporter of the American Revolution. Born the son of a Philadelphia blacksmith, Rush touched virtually every page in the story of the nation’s founding. It was Rush who was responsible for the late-in-life reconciliation between John Adams and Thomas Jefferson. This week we speak with the author Stephen Fried about his new book, Rush: Revolution, Madness, and Benjamin Rush, the Visionary Doctor Who Became a Founding Father.
