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.
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.
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.

As usual, Little Bobbie, you do not keep up on real facts, just the leftwing narrative. The German Health Minister not long ago revealed the results of their government's study on the effectiveness of the Pfizer vaccine, the one most used in Germany. He did not reveal the results voluntarily but only after an opposition member of the Bundestag used a parliamentary inquiry to force disclosure.
That study involved over 45,000 people, half given the Pfizer vaccine and half given a placebo, and then their Covid history was followed, with the key metric being how many died of Covid. The German Health Minister was compelled to reveal that there was no difference whatsoever in Covid deaths between the two groups, meaning the vaccine did nothing. Then there are the stasitics from Taiwan, which only counts people who died from Covid itself, not just with Covid, as Covid deaths. Their statistics showed slightly more deaths from the Covid vaccine (not sure which one was used there) than from Covid itself. |
The vaccine did far more good than harm. Thanks Mr Trump. At least you got that right.
