I posted a long thread of 25 tweets summarizing what we know about myocarditis after Covid-19 infection versus vaccination. Here it is in article form.

🧵 The apotheosis of a catastrophic reign. Dr. Fauci gets every detail about myocarditis flagrantly wrong. https://t.co/ZGruSCkBmo

Anthony Fauci disinforms the public about the relative incidence of myocarditis from COVID vs myocarditis from the vaccine. And in the context of the football player being discussed, omits mentioning that young men are the highest risk demographic for vaccine-caused myocarditis. https://t.co/5y1ZeettN5

Dr. Fauci says myocarditis (heart inflammation) is more common and more severe with Covid-19 infection than vaccination, which, he asserts, is extraordinarily rare and mild.

But why are cardiac problems and deaths so much more frequent in 2021 and 2022 than 2020 and before?

In 2020, the BigTen conference looked for Covid-19-related myocarditis in athletes and found 6 cases with elevated troponin levels and 5 with abnormal ECG. But no hospitalizations or bad outcomes. Satisfied, BigTen did not continue screening program. jamanetwork.com/journals/jamac…

Studying autopsies, Fox & Vander Heide found “histologically confirmed lymphocytic myocarditis is not common in COVID-19.” Caforio found same.
@P_McCulloughMD’s conclusion pre-vaccine was that the Covid-19 virus is a “negligible risk” for myocarditis. journals.sagepub.com/doi/full/10.11…

Btw, myocarditis can raise risk of arrhythmic trouble’s immediately and for many years to come.

When the FDA and CDC were forced to admit a myocarditis problem in May 2021 — because of an independent analysis of Israeli data — they asserted a rate of around 60 per million.

So when Pfizer and Moderna asked for full FDA approval, the FDA insisted both companies do prospective cohort myocarditis studies.
Neither performed the required research.

But Thailand did: Mansanguan et al looked at 301 teen hearts both before and after Pfizer vaccination. And found a rate of myopericarditis of 2.3%.

So did Switzerland: Christian Mueller and colleagues from Basel looked at 777 healthcare workers pre- and post-Pfizer and found a significant troponin rise, signaling myocarditis, in 2.8% – this time, mostly among young and middle aged women.

Sharff et al at Kaiser Permanente found 537 per million.
But those were indirect record searches.

The Thai and Swiss direct prospective studies found clinical+subclinical myocarditis could be more like *20,000-25,000* per million.
That’s a rate more than 300x the CDC’s early estimate and ~5,000x the background rate.

As for infection- versus vaccine-induced, a huge 23 million person study of four Nordic countries found 5x-13x more myocarditis after vaccine than infection. But even this was under -estimate because based on hospital records.

German pathologists did autopsies on 25 who died at home within 20 days of vaccination. They found 18 died of common vaccine effects (stroke, embolism, etc) and 5 probably died of vaccine-induced myocarditis (Spike protein in the inflamed heart muscle).

There’s also a case of fatal myocarditis with the Novavax vaccine, which also implicates the Spike protein itself because Novavax has no LNP or mRNA. Kim et al…By contrast, autopsies suggest infection-based myocarditis is not “a thing.”

Andrew Bostom, MD, MS @andrewbostom
@TracyBethHoeg @JAMACardio @drdrew @contrarian4data @anish_koka Autopsy data raise serious concerns about the basic validity of "C19 myocarditis," as a phenomenon; In stark contrast, autopsy studies validate post-C19 mRNA vaccine myocarditis as real phenomenon.

The bio mechanism is thus more than confirmed. And it is not extraordinarily rare. Or even rare.
Moreover, the Swiss and German studies found many cases in middle aged and older people, including many women, not just young males.

mRNA vaccines generally produce vastly more Spike, for longer, in more body tissues, than infection, which is often defeated before it spreads widely.
Dr. Fauci had everything backwards.
Unfortunate epilogue: unlike most other tissues, the heart doesn’t heal, it scars.

P.S. This thread was informed by @anish_koka, @TracyBethHoeg, @andrewbostom, @P_McCulloughMD, @AndrewFoy82, @VPrasadMDMPH, @Johnincarlisle and other cardiologists, physicians, and scientists, who may not agree w my conclusions. Thanks for their expertise and willingness to share, even when unpopular.


Cognitive warfare: get every detail wrong so that we scurry to do the work for nearly free. All opposition remains exhausted and starved. It's a sick and disturbing strategy.
Do you have a full citation for Avolio et al? I am having a hard time locating that paper.
