Covid Vaccines’ Spike Proteins Cause Anomalies in Heart Cells

Written by Marina Zhang on October 27, 2023. Posted in Current News

New research observing rat and human heart cells shows that within 48 hours of vaccination, the COVID-19 mRNA vaccines form spike proteins

Spike proteins, made from the mRNA instructions inside the vaccines, were detected in the heart cells. While both Pfizer and Moderna vaccines caused cell abnormalities, the two induced different anomalies.

The different responses the cells had to the two mRNA vaccines suggest an mRNA toxicity reaction in these cells, according to Dr. Peter McCullough, a leading internist, cardiologist, and epidemiologist who has published over 1,000 research reports and is the lead author of one of the first widely utilized treatment regimens for SARS-CoV-2 patients.

He added that 48 hours was a short amount of time to observe this.

The paper is a rapid communication paper, meaning it is a shorter scientific paper published more quickly than a standard research article. Scientists tend to use this format when they have findings that need to be shared immediately with the academic community.

Not classic presentations of Myocarditis

The paper’s authors introduced mRNA vaccinations to cell cultures made from rat and human heart cells.

Moderna and Pfizer vaccines each have different doses of mRNA, with Moderna having a higher dose of 100 micrograms compared to Pfizer’s 30 micrograms. Therefore, the researchers administered 100 micrograms of mRNA for both groups.

Within 48 hours, researchers detected spike proteins in both cell cultures and noticed abnormalities in heart contractions.

The researchers recorded heart contractions in a supplementary video, comparing normal contractions in an unvaccinated rat heart cell (1A) with vaccinated cells.

Pfizer-vaccinated cells displayed stronger, sustained contractions (1B) due to increased protein kinase A (PKA) activity. PKA levels are linked to heart performance; the higher the PKA level, the stronger the heart contractions.

Moderna-vaccinated cells developed irregular heart contractions and disrupted calcium regulation. The authors attributed the change in cell activity to disturbances in RyR2 receptors. These receptors play a key role in coordinating heart contractions using calcium.

Some of the heart muscles administered Moderna vaccines developed irregular and peristaltic contractions (1C and 1D), whereas others had irregular and arrhythmic contractions (1E and 1F).

Spike proteins were also detected within 48 hours in the cell culture of human cells.

The authors concluded that at the cellular level, the effects of the COVID-19 vaccines seemed to align closer with cardiomyopathy than with myocarditis. Cardiomyopathy is a condition where heart muscles become both structurally and functionally abnormal in the absence of other heart diseases.

This differs from myocarditis and pericarditis, which occur when heart muscles become inflamed and damaged.

A diagnosis of myocarditis and pericarditis indicates inflammation and damage to heart muscle cells, yet doctors may fail to find signs of damage and inflammation in blood and imaging tests.

“The present preclinical cardiac safety data point to the need for a reassessment of the risk–benefit ratio of RNA-based SARS-Cov-2 vaccines, given indication of their cardiotoxicity,” the authors wrote.

The heart abnormalities exhibited in the cells, likely caused by disruption to RyR2 and increased PKA protein levels, “are risk factors for sudden cardiac death, ventricular tachyarrhythmias, and contractile dysfunction,” they added.

“It’s very worrisome,” particularly since disruptions to the RyR2 receptor are directly linked to sudden cardiac death, Dr. McCullough said. “The pattern we’re seeing is people take the vaccine, and they die during exercise, or they die between 3 a.m. and 6 a.m.—again, where there’s a surge of catecholamines or stress in the body.”

If the two vaccines provoked a similar response, that might suggest that most of the adverse events were driven by the spike proteins produced by the mRNA instructions. However, Moderna and Pfizer vaccines distinctively inducing different cardiac abnormalities may suggest toxicity of the mRNA itself.

“It may just be the mechanics of forcing heart muscle cells to produce an abnormal protein that is changing the function of the heart muscle cells, and my concern is that if it does it with these messenger RNA vaccines, it’s very likely that the influenza mRNA vaccines and RSV and the other ones in development—they’re [all] going to have cardiac toxicity,” Dr. McCullough said.

A Japanese study published in September examined PET scans of 1,000 people who needed medical imaging for a reason unrelated to myocarditis.

The authors compared 303 unvaccinated to 700 asymptomatic vaccinated people. Overall, vaccinated people saw a shift in metabolism, suggesting abnormal heart function.

Typically, heart muscle cells rely on fat for fuel, but the hearts of vaccinated people showed a more substantial reliance on 18 fluorodeoxyglucose, a type of glucose.

A Harvard study published by npj Vaccines also found COVID-19 mRNA in the hearts of people who had died within 30 days of taking the COVID-19 vaccine.
