Another strange thing about this article in the CDC’s peer-reviewed journal is that because the author used chatgpt to research it, it does not cite the CDC’s own research on smallpox and instead pulls random numbers from my book and some other odd sources.

I’d like to be flattered for being cited so extensively in the cover story for the most recent issue of the CDC’s journal Emerging Infectious Diseases, which features an article on George Washington’s decision to inoculate the Continental Army. wwwnc.cdc.gov/eid/article/...

recently read The Contagion of Liberty, about smallpox inoculation in revolutionary America. people who don't like vaccines don't remember that for smallpox, the founding fathers would have expected the town to build a fence around your home and post guards if you had it. that was liberty to them!

As bad as this is for science and for health, it’s also fundamentally unamerican to be opposed to vaccination and vaccination research. George Washington called for "a Law to compell the Masters of Families to inoculate every Child born within a certain limitted time under severe Penalties."

Congratulations Abdul!!!! I can’t believe I know a Democratic nominee for Senate! Or that this picture was 11 years ago. The idea of Abdul being in the Senate advocating for public health and access to health care, especially at a time when RFKJ is in charge at HHS, is incredible to contemplate.

Amazingly, this is not a unique experience! “In 2003, a librarian in New Mexico opened a book and an envelope containing lesion crusts fell out of the book (Figure 3, panel C). The envelope was labeled “scabs from vaccination of W.B. Yarrington’s children,” and the book was dated 1888.”

Enjoy fireworks on the 4th? Thank vaccines for making this (still dangerous) activity safer! Before routine vaccination for tetanus in the 1940s, the patriotic spirit every 4th of July was muted shortly thereafter when newspapers reported deaths from lockjaw (aka tetanus) in the days that followed.
"Glorious Fourth and Its Lockjaw" Headline from the Richmond Item in Richmond, Indiana in 1908."More Victims of Fireworks: Lockjaw Reaps a Rich Harvest in Many Places" Report from the Baltimore Sun, July 16, 1903 detailing a few of the fireworks deaths from across the country.Before the 4th of July in 1908, the Indiana Board of Health produced a report on fireworks and lockjaw and discovered that 60% of the 64 deaths in the state the previous year from lockjaw occurred in July, likely caused by infections after fireworks.Headline: "Advises Vaccine for Fireworks Injuries" The cause of tetanus was discovered in the 1880s and the first vaccine began to be produced in the 1920s. Here the city health department in Lansing, Michigan calls for the use of tetanus vaccine for the public on July 3, 1923, as the army was starting to do for gunpowder burns. Routine vaccination for tetanus nationwide was not available until the 1940s.

Much is made of the 27 grievances in the Declaration and how some of them are thin or contrived. It’s really a wonder that blaming the King for spreading smallpox among them. It was widely thought that the British army was purposely trying to infect both the Continental Army and the American people🧵

Today is the 250th anniversary of Boston’s mass inoculation against smallpox on July 3, 1776. The city was effectively closed to commerce from July through September 1776. The mass immunization effort was cheered as evidence of true independence. Here's how I described it in my book:
While John Adams and fifty-five men in Philadelphia debated a resolution on independence and the final wording of the Declaration of Independence, the people of Boston declared their own independence from smallpox. The measures taken in both cities provided hope that America would not only be a republic free of a king but also a country free from disease. On July 3, 1776, a day after independence was declared in Philadelphia, the Massachusetts General Court voted to allow inoculation. Despite the dangers of infection, the people of Boston and the surrounding areas cheered the news. Ezekiel Price, a court official and insurance broker, declared “Liberty is given for to inoculate for the small-pox; many begin upon it this afternoon.” Hannah Winthrop described the scene: “Boston has given up its Fears of an invasion & is busily employd in Communicating the Infection. Straw Beds & Cribs are daily Carted into the Town.” She wrote that “Men Women & children eagerly crowding to inoculate is I think as modish as running away from the Troops of a barbarous George was the last year.” Dr. James Warren wrote to John Adams that the “rage for inoculation” had “whirled me into its vortex.…”  Warren and his wife Mercy Otis joined Abigail Adams and her four children who had been invited to be inoculated at Abigail’s uncle’s house in Boston along with Abigail’s sisters Elizabeth Cranch and Mary Shaw and their families. Even though Boston was teeming with the sick, the prospect that the city could conquer smallpox made it "a scene delightful indeed." Cotton Tufts was satisfied that he could now "take my leave of Earth, satisfied that the Day of American Redemption was at Hand."

I’m happy to have had my research featured in this piece for @wgbh.org! It’s a short version of the arguments I made in my book, namely that revolutionary Americans understood their government had a duty to protect them from epidemic disease. www.wgbh.org/news/local/2...

The other enemy America was fighting 250 years ago: Smallpox
As smallpox spread, colonists equated public health with self-governance, demanding that local officials track outbreaks and protect the public from contagion.

You’re probably asking in this 250th anniversary of 1776: “how did Americans in the Revolutionary era handle people who tried to leave quarantine early?” Well, in 1774, sailors in Mass. threatened to kill patients who broke quarantine rules and later burned the hospital that allowed early exits.
