Peter A. McCullough, MD, MPH® engagement report
@P_McCulloughMD - 1.3M followers on X
Measured over 120 original posts from a 30-day window, last computed on October 24, 2026.
Engagement
A typical post picks up 284 interactions against 1.3M followers, an engagement rate of 0.023%. Measured over 120 original posts, its engagement rate beats 46% of 20,182 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 30K times each, and 0.951% of those impressions turn into an interaction. That is about 2.38% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 11.2 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 10:00 UTC, and Wednesday is the busiest day of the week. Of the 120 posts sampled, 98% carry an image or video and 5% link out. The account's strongest tracked post pulled 46K interactions, about 164x its own typical post. Recurring topics include #bloodclot, #flyeaglesfly, #jalenhurts.

Compared with accounts its own size
Peter A. McCullough, MD, MPH®'s engagement rate beats 46% of the tracked X accounts closest to it in follower count (20,182 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 46% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 10:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 98% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 5% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 98% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 5% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 360 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

This spine tingling moment just happened at the Sen. Johnson Hospital Protocols Hearing. I can understand exactly why the room erupted. Here’s an attorney with 50 years experience. At the start of covid, he gets flooded with requests to make Hospitals give early treatment protocols. But the result of his work is the part really blew my mind. 95.8% of the cases he won ,to force the Hospital to administer Ivermectin. Survived. But then I heard the contrast of what happened when he lost his cases... the patients who had to go with standard of care hospital protocols which included Remdesivir. Ralph Lorigo Esq. - “Where I lost.... Every. Single. Person. Died” I’m left speechless.

I'm a Board Certified anesthesiologist and have been in practice for 24 years. I just learned that the Children's Hospital of Philadelphia where I trained has launched a program to increase flu vaccine uptake among children by vaccinating them while under anesthesia. The program is called "Close your Eyes. We'll Immunize" This is stunningly irresponsible. Here's why: Anesthetists are extremely risk avoidant and endeavor to minimize patient exposure to anything which carries potential side effects. This is particularly true of pediatric patients who very often have never been exposed to anesthetic medications. We simply cannot know how an individual child will respond to these drugs for the first time. Every single medication we administer during an operation can potentially trigger untoward or allergic responses. When this occurs our primary responsibility is to stabilize the patient. Our secondary responsibility is to identify the offending agent. There is absolutely no justification of introducing another agent, in this case a flu vaccine, which carries a risk of harm and contributes nothing to the success of the operation. Some of the more common side effects of flu vaccines are fever (11-16%) and less commonly, a rash (1%). There is also an non-zero risk of severe allergic reactions and high-grade fevers which can develop over the course of minutes. What if a child under anesthesia receives a vaccine and develops a rash and/or fever? Is it from the antibiotic that the surgeon requested? Is it from the narcotic? The anxiolytic? The barbiturate? Anesthetic gases can also (rarely) trigger a life threatening response called Malignant Hyperthermia which commonly presents as a high fever. Without subsequent testing we cannot know which agent was responsible. Most commonly the testing is never done and the child’s record will forever reflect the possibility that some or all of the drugs which were used are responsible for their reaction. This makes future anesthetic care significantly more challenging and will require the use of alternatives which may not be necessary. Advocating for a flu vaccine while a child is anesthetized reflects the pervasive yet inaccurate attitude among the medical establishment that vaccines are perfectly safe. I simply cannot believe that my mentors would have ever supported this initiative when I was a resident there. Close your eyes indeed.

So it turns out that Fauci was providing cover for CIA Operations during ‘Covid’ and Bill Gates had a ‘Security Clearance’ for the Intelligence Community. NO ONE COULD POSSIBLY BELIEVE AT THIS POINT THAT THEY CARED ABOUT YOUR HEALTH https://t.co/OEIz3IBCEY

Eagles HC Nick Sirianni (if he was fully aware of the situation), along with the entire medical staff, need to be let go over the Jalen Hurts situation. Hurts was told not to sleep, for his safety, after a blood clot was found, and then played a football game on 36 hours of no sleep in London. Now more blood clots have been found and he's out for the season. The level of disregard for his safety and well-being is astounding. People need to be fired. A LOT of people need to be fired.

Mind-Blowing Reality: 81% of Americans COVID-19 vaccinated, 94% of whom have synthetic mRNA in their bodies producing the potentially lethal Spike protein. Unless the library of anti-Spike antibodies is perfectly neutralizing, Spike will cause tissue damage and result in chronic illness. Unnatural, unsafe.

BREAKING: 153 Nations Adopt UN Pandemic Declaration to Push FAST-TRACKED Vaccines Within 100 Days and Crack Down on “Vaccine Hesitancy” UN declaration raises concerns that scientific censorship, lockdowns, and experimental vaccine mandates would be put into place quickly with the next outbreak. Agency confirms the goal of man-made pandemics is global mass vaccination. Strategy doomed to fail as pathogens quickly become resistant to vaccines which should never be the primary pandemic response measure. By Nic Hulscher, MPH, @UN @NicHulscher @McCulloughFund

- What is Peter A. McCullough, MD, MPH®'s engagement rate on X?
- Peter A. McCullough, MD, MPH® (@P_McCulloughMD) has an engagement rate of 0.023%, based on the median interactions across 120 original posts from the last 30 days against 1,256,050 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.023%, Peter A. McCullough, MD, MPH® sits above the 10th percentile of the 204,491 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @P_McCulloughMD have real engagement?
- Its engagement rate beats 46% of the tracked X accounts closest to it in follower count (20,182 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @P_McCulloughMD post?
- Most posts go out around 10:00 UTC, and Wednesday is its busiest day, at roughly 11.2 posts per day across the measured window.
