I could go on and on, but the piece does perhaps surprisingly fully endorse government efforts to inoculate citizens, writing that “[Washington’s order] was an effective, organized public health intervention, demonstrating the capacity of centralized authority to manage disease on a large scale.”

It also likely shows the politics of the current CDC because it does not mention that inoculation was introduced in America by an enslaved Black man named Onesimus. Instead it cites me as it credits Cotton Mather. My book mentions Mather but credits Onesimus.
The text of the article that says “variolation was first promoted in the New World by Puritan minister Cotton Mather.

But the article is very odd. For one it acknowledges that the author used chatgpt to research it (why not reach out to me and have me or another expert write it?)

True, but he did still get nearly twice as many votes as Mike Rogers did in Wayne County.

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 showed this with a shocked face to my wife (who is not a soccer fan), and she too looked shocked and said “how did they get half a goal?!”

My freshman year at the University of Arkansas, my professor wrote this on my first ever research paper. He made copies and put them in other history professors’ mailboxes to read what this freshman had written. (But he still only gave me a 92, ha!)
The top of the first page of a 15-page research paper I wrote in May 2000 for an upper level course on Andrew Jackson taught by Dr. James Chase. His comment reads, “Well-written and organized—unusually so—92”

Kaplan also writes that Congress banned inoculation after the invasion of Canada. It did no such thing. It was Washington who banned inoculation from the outset in the Army. He supported the jailing of inoculators and called for any who inoculated "an enemy and traitor to the country" in May 1776.
An order from Washington praising the New York Congress for jailing an inoculator. Washington wrote that "any Officer in the Continental Army, who shall suffer himself to be inoculated, will be cashiered and turned out of the army, and have his name published in the News papers throughout the Continent, as an Enemy and Traitor to his country."

This is all wrong. Howe and the British famously evacuated Boston on March 17, 1776. There was no direct confrontation with Washington's troops. Washington only sent 1000 immune troops after the British left and not into Boston but to control Dorchester Heights just outside the city.
Letter from George Washington to John Hancock on March 19, 1776. It reads in part "As soon as the Ministerial Troops had quitted the Town, I order'd a thousand Men (who had had the Small Pox) under Command of General Putnam to take possession of the Heighths, which I shall endeavour to fortify in such a manner as to prevent their return should they attempt it."

I appreciated the thorough report! *Thank you* The book doesn’t have a timeline (I’m sure it was harder to keep up with as an audiobook!), but it does have maps and images. Here are a couple of them.
Map of the locations of inoculation facilities in New England prior to George Washington’s order to inoculate the troops in 1777. A page with two images from my book. The top is a portrait of Benjamin Franklin’s son Francis who died in 1736 after the Franklins failed to inoculate him, something Franklin bitterly regretted and caused him to advocate for inoculation throughout his life. On the bottom is the Essex Hospital or Castle Pox that was burned by sailors because it was only serving the wealthy.

Leave it to MAGA and MAHA to bring us back to the measles outbreaks of the Roaring 20s.
New York Times article from April 2, 1926. "Increase in Deaths From Measles. Special to the New York Times. TRENTON, N.J., April 1--A huge increase in the number of deaths from measles during February was set forth in a mortality report issued today by the State Department of Health. During the month there were seventy-three deaths due to measles, while the average for the previous twelve months was twenty-nine deaths. Measles caused twenty-nine deaths in January. In February 1925, there wree ten deaths."New York Times article from Tuesday June 5, 1928. "DANGER IN MEASLES, Disease Now Prevalent May, if Neglected Have Serious Results. To the Editor of the New York Times: Nineteen thousand cases of measles have been reported in New York City already this year and 176 deaths from measles have occurred since Jan. 1. Let us remember that 176 homes have been darkened by death; that if simple precautions had been used in all these cases few if any of these young lives would have been destroyed."

Here's an example of a report from the commission that Gadsden was a part of from 1760. The law required that Gadsden’s committee report all smallpox cases, quarantine them, and keep the public updated on their condition. Gadsden was opposed to arbitrary, lawless government not all government.

I’m currently reading through the wonderful essays in @theatlantic.com’s “The Unfinished Revolution.” The editors included this image of an inoculation certificate, but there’s no essay on the legacy of the Revolution on vaccination and public health. *ahem (I did send in a pitch…so we’ll see?)
On page 130 of The Atlantic’s November issue on the American Revolution is an inoculation certificate from October 1776 for Nicholas and his four children. This certificate allowed them to leave the inoculation hospital and certified that they were no longer infectious. The caption notes that in early 1777 Washington would require the inoculation of the Army, but as my book The Contagion of Liberty shows men, women, and children were already demanding (and receiving) inoculation before Washington gave the order, pressuring him to act.
