A common explanation given for many of the adverse effects seen following injection with any of the COVID “vaccine” products is that the triggering of the immune response leads to various reactions such as fever, pain, and inflammation, and that the COVID shots are not unlike the standard vaccines we are already familiar with. This explanation is challenged by the findings of a recent pre-print study, in which a number of scientists from a variety of institutions compared the adverse events resulting from the COVID shots to those following vaccination for other illnesses.
The researchers focused on one specific group of adverse reactions; their study is titled, “Cardiac Arrhythmia after COVID-19 Vaccination versus Non–COVID-19 Vaccination: A Systematic Review and Meta-Analysis”.
Recently, reports of arrhythmia after COVID-19 vaccination have increased. Whether the risk for cardiac arrhythmia is higher with COVID-19 vaccines than with non–COVID-19 vaccines remains controversial. This meta-analysis explored the incidence of arrhythmia after COVID-19 vaccination and compared it with the incidence of arrhythmia after non–COVID-19 vaccination.
The study’s authors add that just five cases of arrhythmia (of various kinds) have been officially noted in relation to Pfizer’s COVID shots, one from the trial itself and four others unspecified, possibly in post-marketing research.
Using 36 studies going back all the way to 1947 and up to the present day, examining around 1.5 billion vaccine doses, this meta-study examines not only arrhythmia but also tachyarrhythmia (abnormal and high heart rate) and all-cause mortality following vaccination.
Here are their findings:
Average incidence per million doses
95% confidence interval (CI)
Number of studies consulted
|Arrhythmia after COVID shot|
875.4 - 5839.2
|Arrhythmia after non-COVID shot|
1.3 - 75.5
|Tachyarrhythmia after COVID shot|
1535.2 - 12,360.8
|Tachyarrhythmia after non-COVID shot|
4.5 - 149.4
|Arrhythmia after 1st COVID shot|
988.2 - 11,977.6
|Arrhythmia after 2nd COVID shot|
2205.9 - 2320.7
|Arrhythmia after 3rd COVID shot|
5775.5 - 61,051.2
Of all the vaccinations studied here, only the smallpox vaccine led to arrhythmia statistics anywhere near approaching that of COVID, with 1747.5 cases on average per million vaccine doses (95% CI 275.9 - 10,982.9).
While the differences between COVID shots and vaccines for other illnesses were striking, average all-cause mortality differed only slightly and did not reach statistical significance:
COVID-19 shots: 4.5 deaths per million doses (95% CI 0.6 - 34.2) measured in three studies.
Non-COVID shots: 1.3 deaths per million doses (95% CI 0.4 - 4.8) measured in five studies.
However, considering the huge disparity in the outer limits of the 95% CI (34.2 for the COVID shots versus just 4.8 for regular vaccines), one might easily make a case that further research is warranted.
mRNA versus non-mRNA
The authors write:
Among the 23 studies involving COVID-19 vaccination, no difference in the incidence of arrhythmia was found between the mRNA subgroup 1758.3 [95% CI 875.6-3527.7] cases per million doses, 18 studies . . . and non-mRNA subgroup (2528.1 [95% CI 960.9-6634.6] cases per million doses, 18 studies. . .
Here too, while the results may not have statistical significance, given that the outer limits of the 95% CI are so different—almost double in the non-mRNA subgroup—a case might easily be made for conducting further research.
Here it is perhaps relevant to note that all the COVID shots, whether based on mRNA or not, act to introduce spike proteins into the person being injected.
The study’s authors state that “in the general population, the background incidence of arrhythmia is estimated to be 700-23,430 events per 1 million people.”
The huge range between 700 and over 23,000 events per million begs an explanation, which is to be found in the source the authors bring (here). It turns out that 700 cases per million refers to women aged 20-24 years, and 23,430 refers to men aged between 75 and 79. The research paper that provides these figures also notes that the “age and sex standardized cumulative AF [atrial fibrillation] incidence was 0.07%,” in other words, 700 per million events.
Other studies (such as one described here) report far lower figures for arrhythmia in the general population, around 136 cases per million people. It is therefore reasonably safe to assume that the conclusion of the authors of the present study, that “incidence levels fall within the background incidence range, suggesting a low risk for arrhythmia. . .” is not tenable.
The study’s authors also suggest that “arrhythmic events from traditional non-COVID-19 vaccines may have been relatively underreported,” and that the COVID shots therefore appear more dangerous than they actually are, because they are “subject to more stringent monitoring than previous vaccines,” an assertion that many might wish to dispute.
The study’s authors conclude that:
The overall risk for arrhythmia after COVID-19 vaccination was relatively low, although it was higher in COVID-19 vaccine recipients than in non–COVID-19 vaccine recipients. This increased risk should be evaluated along with other important factors, such as the incidence of local outbreaks and the risk for arrhythmia due to COVID infection itself, when weighing the safety and efficacy of COVID-19 vaccines.
They also suggest that people with “known risk factors for arrhythmia” might benefit from being “monitored” when receiving their COVID shots, maintaining that “the risk for such rare adverse events should be outweighed by the benefits of vaccination...”
But who is going to monitor millions of people?
Almost 13 billion doses of COVID “vaccine” have been given so far across the world.
That translates to 28,948,886 cases of arrhythmia – almost 30 million cases.
It translates to 55,860,325 cases of tachyarrhythmia – almost 56 million cases.
Just how dangerous is this?
According to one (pre-COVID-era) study which cites the arrhythmia background rate as 136 per million, “In the United States . . . arrhythmias directly account for more than 36,000 deaths annually and constitute the underlying or contributing cause in almost 460,000 cases.”
This would translate to around 600 thousand deaths directly caused by the COVID shots each year in the U.S. alone, and almost 8 million deaths in which the COVID shots are the underlying cause.
In another study (published in PLoS One in 2018), the death rate from atrial fibrillation, the most common type of arrhythmia, is cited as 63.3 per 1,000 person-years, with patients with AF having a 3.67-fold higher risk of all-cause death than those in a matched population.
This translates to 1,832,465 deaths per year across the world, or roughly a quarter of the total number of people said to have died of COVID (including with COVID) since the virus appeared in late 2019.
