— 75-year literature review finds incidence no different than following non-COVID vaccines
Not only were rates of myopericarditis following COVID vaccination extremely low, but they were comparable to non-COVID vaccines, a systematic review and meta-analysis found.
In an analysis of 11 studies with over 400 million vaccine doses, there was no significant difference in incidence of myopericarditis after COVID vaccines versus non-COVID vaccines (18.2 vs 56.0 cases per million doses, P=0.20), reported Kollengode Ramanathan, MD, of National University Hospital in Singapore, and colleagues.
And compared with COVID vaccinations, there was no significant difference in incidence of myopericarditis after influenza vaccinations (1.3 per million doses, P=0.43), they wrote in Lancet Respiratory Medicine.
"The occurrence of myopericarditis following non-COVID-19 vaccination could suggest that myopericarditis is a side effect of the inflammatory processes induced by any vaccination and is not unique to the SARS-CoV-2 spike proteins in COVID-19 vaccines or infection," said co-author Jyoti Somani, MD, also of National University Hospital, in a statement.
Indeed, Ramanathan's group noted that prior to COVID vaccines, the only vaccines with links to increased risk of myopericarditis were smallpox vaccines.
"Whether these findings reflect a true increase in incidence or merely improved reporting and recall bias remains inconclusive," they wrote.
They searched for studies from Jan. 1, 1947 to Dec. 31, 2021 with a primary outcome of incidence of myopericarditis in temporal relation to vaccination.
Overall, incidence of myopericarditis following vaccination in 22 studies was 33 cases per million doses (95% CI 15.3-72.6).
Myopericarditis was significantly higher following smallpox vaccination (132.1 cases per million) compared to COVID vaccination (P<0.001).
Among COVID vaccines, incidence of myopericarditis did not differ significantly between the adult and pediatric subgroups (26.0 vs 18.4 cases per million, P=0.58).
As other studies have confirmed, incidence of myopericarditis was significantly higher among those who received mRNA vaccines (22.6 cases per million doses), higher in people younger than age 30 (40.9 per million), and higher in males than females (23 vs 5.1 per million). The authors highlighted that "These findings are important additions to the conversation when weighing the risks and benefits of COVID-19 vaccination during this pandemic."
Ramanathan's group also found that pooled all-cause mortality was non-significant when comparing COVID vaccines (8.4 per million) and non-COVID vaccines (7.2 per million, P=0.93).
In an accompanying editorial, Margaret Ryan, MD, and Jay Montgomery, MD, both of the Defense Health Agency in Falls Church, Virginia, characterized myopericarditis following vaccination as "unexpected, but not unprecedented."
They stated that there were "common demographic and clinical features" between myopericarditis cases associated with smallpox and mRNA COVID vaccines. Indeed, Ryan and Montgomery pointed out that U.S. military professionals ("a large number of young men," they noted), who were familiar with adverse events (AEs) following smallpox vaccination, "were among the first to observe myocarditis cases after mRNA COVID-19 vaccines," given that they likely received a two-dose vaccine series in early 2021.
The editorialists also discussed the paucity of information on myocarditis following immunizations other than smallpox or COVID, finding only five publications in a literature review spanning 75 years.
"Among the populations who received billions of vaccine doses after which myopericarditis was not observed or very rarely observed, published literature might not exist; reassuring data from background populations would not be captured in analyses of the literature," they wrote, adding that it is important to fully investigate these AEs, given their link to vaccine confidence.
"Alternative vaccine platforms, vaccine doses, or vaccine schedules could reduce the risk of rare adverse events and must be explored in the context of changing infection risk," Ryan and Montgomery added.
Study limitations included that the findings are not generalizable to children ages 12 years and younger who received the COVID vaccine, and that the vaccines were compared across different time periods, which could lead to potential confounders. Lastly, vaccines against hepatitis, Haemophilus influenzae, pneumococcus and diphtheria, pertussis and tetanus were underrepresented in the literature review.
According to this article, there was only 18.2 cases of myocarditis per one million vaccinations.
Uh huh sure
“Ramanathan's group also found that pooled all-cause mortality was non-significant when comparing COVID vaccines (8.4 per million) and non-COVID vaccines (7.2 per million, P=0.93).”
The medical/scientific/pharmaceutical industries have so corrupted their integrity that nothing they say is regarded as true. NOTHING. EVEN IF, IN FACT, IT IS.
One, they're not vaccines regardless of what they CDC changed their definition to, and two, I recall seeing healthy athletes collapsing all the time when they got other actual vaccines.
I notice they don’t say where they got their figure for the rate following COVID vaccinations.
Covid itself is causing heart issues. Likely people are lumping together an issue after they get the vaccine , when it was Covid causing the issue.
And once the issue turned political , all reasonable discussion goes out the window on both sides .
Your recollections are valuable, but do you have any evidence there’s a higher rate of cardiac problems in athletes lately?
This is bogus.
Primary care providers can give out every other vaxxes but CoupFlu, not unless they pregister with Fedzilla and most haven’t.
I’m thinking Deep State did it this way, keeping PPCs out of the loop to get around VAERS.
Deep State wouldn’t do that for comparable numbers of injuries.
And if people remember of Swine Flu vaxx debacle from 1976, that vaxx was pulled after causing fewer than 3 dozen deaths.
But not the coof vaxxes.
Sure. CYA
Family member died from blood clots caused by the booster. He never had covid
Sure they do.
”We did a systematic review and meta-analysis, searching four international databases from Jan 1, 1947, to Dec 31, 2021, for studies in English reporting on the incidence of myopericarditis following vaccination (the primary outcome). We included studies reporting on people in the general population who had myopericarditis in temporal relation to receiving vaccines, and excluded studies on a specific subpopulation of patients, non-human studies, and studies in which the number of doses was not reported.”
There are links to all of the studies at the end of the paper.
Two Words: Operation Mockingbird
Yes, I read that part and it certainly explains how they got the rate for previous vaccinations. It doesn’t specifically say that is how they got their rate for COVID vaccinations though.
If that is the only clue they give, then I wonder, how many studies exactly were published before December 2021 on the rate of myo and pericarditis post-COVID vaccination, and which met their criteria?
That’s the same idiotic study that relies on a Wikipedia page where internet randos can report stuff they might have seen in the news.
Do you have any evidence there’s a higher rate of cardio problems in athletes lately?
“Family member died from blood clots caused by the booster. He never had covid“
Sorry to hear, that really sucks.
Propaganda. Heart issues are through the roof with COvid ‘vaccines’ and after the propaganda storms are pierced with lawsuits, stupid fake articles like this one will be incriminating evidence of collaboration. When compelled to explain how they obtained results opposite that of world-wide undeniable reality, their feeble attempts to justify their propaganda won’t be pretty.
How’s this for a tell: Sports physicals are now including bloodwork and cardiac screenings.
