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/...

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?)

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!

All the Founders would be aghast J. Adams: “To disarm the Small Pox of its contagion [via vaccine] is an enterprize worthy of a Hercules in medicine.” T. Jefferson: “every friend of humanity must look with pleasure on this discovery, by which one evil is withdrawn from the condition of man.”

After calling for the inoculation of the Continental Army, Washington wrote: “I shudder when ever I reflect upon the difficulties of keeping [smallpox] out [without inoculation].”

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."

Sure, but even in the contested Republican gubernatorial primary in Wayne county there were only 76,000 Republican votes total. El-Sayed got 133,000 against Stevens (150,000) in Wayne County. Are you suggesting he won’t decisively win Wayne County? That the Stevens voters will vote Rogers?

Andrew Wehrman @profwehrman.bsky.social · 07/08/2026
True, but he did still get nearly twice as many votes as Mike Rogers did in Wayne County.
Wayne county primary election results: Stevens: 150,593 votes, El-Sayed, 133,292 votes; Roger’s 72,819 votes.

Quizbowl coaches used to swap questions a lot. The top teams had big question libraries. I remember that we always stayed to the end and collected packets from the host. I wonder if that’s what he’s talking about—that they have amassed that many (recycled) questions from old tournaments.

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.

If Abdul El-Sayed wins the primary in Michigan today and goes on to win in November, he will be the first Democratic Senator to hold and medical degree and be a public health expert since Sen. Royal Copeland (former NYC health commissioner) died in 1938.

And, I should note, I was featured on El-Sayed’s podcast America Dissected back in 2023 to talk about my book. El-Sayed certainly understands that public health has been and should be a primary duty of government dating back to the founding of the country. crooked.com/podcast/the-...

*You might say, "AHA! Wehrman doesn't know what he's talking about! What about Senator Ernest Gruening (1959-1969)?” Well, Gruening did graduate from Harvard Medical School in 1912, but he never practiced medicine or served in a health department and instead made his career in journalism.

But the Democratic Party which passed Social Security, Medicare, Medicaid, and Obamacare has somewhat oddly not had a physician, epidemiologist, or other public health doctor in the Senate since Royal Copeland.* Fighting RFK jr. and health misinformation seems to require real expertise in the Senate

In recent decades Republicans have elected several physcians, who mostly come from backgrounds in private medical practice (Mehmet Oz, Rand Paul, Bill Cassidy, Roger Marshall, etc.) and have used their Senate careers to vote against public health initiatives and national healthcare programs.

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.”

I hope they also took “coercive” on that vague intolerable acts question. No contemporaries called them the “intolerable acts!” And there were many groups of laws referred to by adjectives. Argh. (Despite my gripes I’m kicking myself for not signing up for this!)
