Certain Covid-19 vaccines can trigger immune responses that may inflame heart tissue and lead to potentially fatal complications in rare cases, with young men being especially susceptible, according to a new study.
The paper, authored by Stanford University researchers and published in the Science Translational Medicine journal, examined why some patients developed myocarditis or pericarditis after receiving mRNA jabs such as those produced by Pfizer and Moderna.
Researchers found that immune cells can, in some cases, recognize the foreign RNA delivered by the vaccines and mount a strong response. In rare instances, this response has led to the release of large amounts of cytokines – immune-signaling proteins that can damage heart cells.
Vaccine-associated myocarditis has occurred in about one in 140,000 people after a first dose and around one in 32,000 after a second dose, according to figures cited by The Telegraph, with incidence peaking among males aged 30 or younger.
Symptoms have included chest pain, shortness of breath, fever and palpitations, typically appearing within days of vaccination. Most patients have recovered quickly, although hospitalization and deaths have been reported in rare cases.
The findings come as the US Food and Drug Administration reportedly intends to place a “black box” warning, the agency’s most serious safety label, on Covid-19 vaccines, according to CNN. The warning would alert consumers to risks such as myocarditis and pericarditis, although the plan has not been finalized.
Covid-19 vaccines were developed and authorized rapidly after the World Health Organization declared a coronavirus pandemic in March 2020 and were later mandated in many countries. The rollout proved controversial, with critics claiming the jabs were poorly tested and that side effects posed greater risks than the virus itself.
However, scientists and regulators have maintained that Covid-19 infection carries a greater overall risk of serious illness and long-term complications than vaccination, and have stressed that the benefits of immunization outweigh the short-term risks of rare heart-related side effects.

Eamonn Holmes says ‘wokeism’ is ruining TV and bosses ‘scared’ of hiring heterosexual presenters
Story by Hannah Mcdonald • Eamonn Holmes has claimed ‘wokeism’ is ruining TV by employing seriously sexually damaged
presenters
The GB News presenter, 66, made the comment as he appeared on his son Declan’s new podcast Founder&Family Collective on Friday. During the episode, Eamonn moaned that television nowadays is ‘pathetic’ and TV execs don’t want to hire people who are likely to offend minorities
The TV conjuror Pail Daniels was taken off air for ” flirting with his pretty wife Debbie Mc gee
Paul was replaced by ” boy-nobber” derren brown whose TV skits have to be filmed dozens of times to get them right
and Tom Jones was taken off TV screens for being ” too hetero
Eamonn claimed examples of people the industry doesn’t want to platform anymore include Jeremy Clarkson, and Piers Morgan
This is despite the fact that Clarkson has not one but two shows, Clarkson’s Farm on Amazon Prime and Who Wants To Be A Millionaire on ITV, while Morgan makes regular guest appearances on ITV’s morning talk shows and highlights from his show Piers Morgan Uncensored are shown weekly on Channel 5.
I always said us unvaxed were in for some good bargains when the vaxed C..ts die shortly. Do I care about them, no not at all.
Dear stanford BUSINESS SCHOOL,
Know thanx,
A. Slave.
Plandemic scamdemic and the usual suspects made billions in profits and killed thousands and thousands with their bioweapons vaccines. And all vaccines are bioweapons, all for profits at 67 billion dollars in annual revenues. I wish people would go down a the rabbit hole to discover the history of the medical/big pharma fraudulent and corrupted industry.
There is and never was a ‘COVID’. Thats the real story.
young milenials get heartdesease ? does vnot
matter . they are good for nothing anyway as
I see in my place . specialy the leftgreenliberals !
and the office furzers .
The REAL limited hangout underlying a superstructure of deceits – like vaccination – is germ theory.
GERM THEORY IS THE BIG LIE THEY NEED TO PROTECT.
TPTB by ignoring the terrain – from the smokestacks of the nineteenth century, to pesticides in the twentieth, and to EMFs now – can profit from various industries that disregard human safety. By the same token the notion of microbes being vectors of diseases allows “interventions” – life shortening jabs – to feign “treatment” while shortening life spans.
Thus the returns on capital investments favour the wealthy while deferred wages in the forms of pensions are no longer paid because the elderly – and others – are being killed off.
***
Germ theory is thus a multi-purpose tool for TPTB. And as I keep saying in these comments, the geopolitical chess players like moves (ideas) that serves different functions – killing two or more birds with one stone if you will…
By all means learn jujitsu for everyday survival, but the “general’s martial art” is chess….
LOL…
back in the day, the rubber faced imbecile and CiA impresario William Casey supposedly said..
“We’ll know our disinformation program is complete when everything the American public believes is false”*..
Nowadays fact checked and declared false, because it’s probably true..it should probably run thus..
“We’ll know our disinformation program is finished when everything the American public believes we say is false”…
you see, whether it’s true or false is irrelevant to the common man.. what is important is fitting in, that way HIS whirled view stays intact…
* it already was and had been for some centuries…
IMHO the “spanish”flu + polio was Rockefeller
invented like the whole modern chemical medicine
is Rockefeller based keeping the korrupted medics
dependent from jewpharma .
the old german doctors had profssional ethos
what most young today not have anymore .
and never trust the dentists offering you their trap .
The jew jab may as well cause heart damage…to go along with the catastrophic brain damage the recipients already had. The clot shot vaxxx solution of rat shit and toxic sludge was a f*cking IQ test, and a vigorous pimp-slap across your yaps with a giant rubber dong, rather than any sort of preventative treatment….for the seasonal f*cking flu…..
Nobody regrets NOT getting injected with that shit…but I know know several people on the flip side with sucker’s remorse.
@ UMBRA BELLATOR
NO IQ test . it was a test of natural instinkt, more
a belly IQ test . one here his most academic colegs
took the shots free willy . its not the brain IQ .
Did not stop you from CATCHING covid and it did stop you from SPREADING covid! So what was the point? The covid manly effected the elderly those over 60. If you were under 60 there was no point in getting it! Also anybody under 30 and especially children. But it was all about the money and every nation pushed the LIE and even to today! But there are suckers born everyday who lack critical thinking skills. Read the article carefully notice how it dances around the Truth, the author is afraid to speak truth! Afraid of losing his/her job or being ridiculed by their colleagues! Notice how the article fails to mention the increased overall death rate in every country across the globe ? Some places , well most countries it’s up 18%! A vaccine that doesn’t stop transmission or catching it is not a vaccine it’s a LIE. Remember grandma died but you couldn’t be by her bedside, why stupid. But go back to sleep world I can see the end from here!
Sadly, all this heart disease and mortality in young people may just be a cosmetic issue in the grand scheme of things.
From what I’ve read, there is a good chance that the jab was just one component in a pervasive combo of factors that may ultimately be activated to take over everyone’s brain. So, on balance: Dropping dead of a heart attack – I can accept; but to have Big Tech implant fake memories and other fake cognition in my head – I’d hate to experience that.
