Myocarditis Risk Following mRNA COVID Shots May Be Far Higher Than Previously Estimated

Myocarditis Risk Following mRNA COVID Shots May Be Far Higher Than Previously Estimated

A new study conducted by researchers from the U.S. Centers for Disease Control and Prevention (CDC) and several universities and hospitals in the United States shows that the risk of myocarditis (inflammation of the heart muscle) after receiving a messenger RNA (mRNA) COVID-19 biologic is 133 times greater than the normal risk for the condition in the general population. The researchers, who used data from the CDC’s Vaccine Adverse Event Reporting System (VAERS), noted that, given the passive reporting nature of VAERS, the risk of myocarditis is likely to be even higher.1 2 3 According to the study:

[A]s a passive system, VAERS data are subject to reporting biases in that both underreporting and overreporting are possible. Given the high verification rate of reports of myocarditis to VAERS after mRNA-based COVID-19 vaccination, underreporting is more likely. Therefore, the actual rates of myocarditis per million doses of vaccine are likely higher than estimated.2

The study, which was published on the JAMA Network on Jan. 25, 2022, evaluated the effects of Pfizer/BioNTech’s experimental BNT162b2 (“Comirnaty”) product and Moderna/NIAID’s experimental mRNA-1273 (“Spikevax”) using VAERS data collected from December 2020 through August 2021. A total of 1,626 cases of myocarditis were reviewed. Eighty-two percent of these cases were among males and the median age was 21 years old.1 2 3

The median time for the onset of myocarditis symptoms after vaccination was two days and 90 percent of the symptoms occurred within seven days after the second dose of the shot. The rates of myocarditis cases were highest (one in 9,500) after the second dose in adolescent males 16-17 years old and second highest (one in 14,000) in adolescent males 12-15 years old.1 2 3 4

The typical symptoms of myocarditis include:

    • Chest pain
    • Rapid or irregular heartbeat (arrhythmias)
    • Shortness of breath, at rest or during activity
    • Fluid buildup with swelling of the legs, ankles and feet
    • Fatigue
    • Other signs and symptoms of a viral infection such as a headache, body aches, joint pain, fever, a sore throat or diarrhea4

“Sometimes, myocarditis symptoms may be similar to a heart attack,” states the Mayo Clinic.5

Long-Term Prognosis of Patients Suffering Myocarditis Following COVID Shots Unknown

The study found that about 96 percent of those who came down with myocarditis after COVID-19 vaccination were hospitalized. Most of the patients developing myocarditis were treated with nonsteroidal anti-inflammatory drugs and approximately 87 percent them reportedly experienced resolution of their symptoms by the time they were discharged from the hospital.3 However, it is unclear whether these individuals, who appear to have recovered, will suffer any long-term health effects. The study noted:

The CDC has started an active follow-up surveillance in adolescents and young adults to assess the health and functional status and cardiac outcomes at 3 to 6 months in probable and confirmed cases of myocarditis reported to VAERS after COVID-19 vaccination.2

As a precautionary measure, the study researchers cited guidelines from the American Heart Association (AHA) and the American College of Cardiology (ACC) advising that myocarditis patients should “refrain from competitive sports” for three to six months and that “documentation of a normal electrocardiogram result, ambulatory rhythm monitoring, and an exercise test should be obtained prior to resumption of sports.” Both the AHA and ACC recommend that those who have developed myocarditis after getting an mRNA COVID biologic should “defer” further doses of the product. They add that further doses “may be considered in select circumstances.”2 3 6

CDC Study Findings of COVID Shot-Related Myocarditis Risk Consistent With Other Studies

Cardiologist Biykem Bozkurt, MD, PhD, who has extensively researched the association between the mRNA COVID biologics and myocarditis, believes the latest CDC myocarditis study confirms previous similar studies by the federal health agency and others regarding the higher risk of the heart condition in adolescent males boys and young men after the second dose of the shots.1 7 8 9 10 11

The CDC study also reinforces data from an Israeli study reported on Jan. 26, 2022 regarding the increased rate of myocarditis in adolescent males 12-15 years old after receiving Pfizer/BioNTech’s BNT162b2 biologic. The Israeli study, based on data from Israel’s Health Ministry, found that myocarditis occurred in one out of 12,361 boys within a week after getting the second dose of the shot.12 13

    My muscle testing explorations of these shots makes me suspect that all the vaxed have some degree of subclinical autoimmune myocarditis. Historically, I miss things that are present but rarely find things that are absent. Time will tell.

    Unbiased articles about this study always include a comparison of Covid-19 induced myocarditis, which this article fails to mention. This article also exaggerates the risk of vaccine induced myocarditis. Covid-19 causes much higher rates of myocarditis compared with vaccination and Covid-19 induced myocarditis is associated with increased death. Whereas two new studies affirm that vaccine induced myocarditis is more rare and had a milder course that resolved with pain medication with no adverse outcomes and no deaths.

      Comparing alleged rates of myocarditis among vaccinated age groups with alleged rates of myocarditis among similar age groups of Covid-19 victims is not the same as comparison with total unvaccinated similar age groups. Shouldn’t any comparison be vaccinated vs unvaccinated?

        Yeah, that will never be supported by our government, tho! Just like vaxed vs unvaxed studies for all the childhood vaccines are not supported by the govt. Small scale studies have shown so much harm to the vaxed. Could you imagine if a similar study would be done for the covid jab? Based on the VAERS data, and the boosters increasing odds of infection, the outcomes of vaxed vs unvaxed would be very interesting!

      You have no long term data to show what happens in 5 years for those with vaccine-induced myocarditis. It’s ludicrous for teens to be forced to sit out their senior year in high school sports for a vaccine injury, when covid would’ve been a cold to their young, healthy body. And to top it off, soooo many that got vaccinated (and even boosted) are getting omicron. So, they take on the risk from the jab AND the risk from the virus…it’s a lose-lose for those that thought they were going to be safe, and even believed they were protecting others. So sad they were lied to.

    Doesn’t matter. The mRNA injections have murdered 100’s of thousands and injections are being pushed by the corrupt CDC. This has been a completely useless agency for 70 years always looking to invent the next medical panic so useless big pharma drugs can be pushed on millions. Every time the CDC goes into panic mode, it is a fake event.

    Jim is calling for consideration of the rates of myocarditis in the vaccinated compared to the infected. However, that’s a straw man. The choice of moving from the unvaccinated, uninfected group into the vaccinated, uninfected group dictates the relevant comparison (vaccinated vs. baseline). Further, the vaccinated ALSO can then be infected, and, due to pathogenic priming, might experience pathogenic priming. Absent studies of risk of myocarditis in the “vaccinated then infected” vs. “unvaccinated then infected”, comparisons to the rates in the vaccinated are arm-waving and are not helpful.

    No one is ever offered “vaccination or infection” in the clinic; informed consent is required by law, and this article places the focus on the correct risk consideration.

    I am personally pretty cautious about vaccines but the rates of myocarditis following Covid infection are far higher than following vaccination. And long Covid symptoms are extremely concerning, the patients that I work with would give anything to go back in time and get the vaccine.

      I don’t doubt what you’re experiencing. Sounds like you’re seeing plenty of sick patients, and your data might be skewed. But, I do wonder about that argument because not everyone gets covid. So, it’s hard to compare apples to apples, when you don’t know how many in the population are susceptible to covid and myocarditis. Some seem to have immunity built up and never get it, while others have natural immunity, so they’re protected for maybe a year. I just had omicron, so at this point in the pandemic, I feel the risk of the jab outweighs my risk from covid. Also, I’ve researched early treatment, so am confident that I’d be OK if I were to get another variant. We will never have enough accurate data to know the real risk vs benefit for all the age groups.

    A claim of “mRNA injections have murdered 100’s of thousands” not only lacks any evidence whatsoever, it lacks common sense observation. Personally. in my work the last 2 years on zoom I’ve met with about 2,000 people. 40 or 50 or so were healthcare workers in hospitals. I’ve not heard of a single case of someone hospitalized because of a vaccine but i heard dozens of first hand stories of family members who died from covid. The healthcare workers speak of wave after wave of overflowing covid patients and in 2021 they say the vast majority of deaths and ICU patients were unvaccinated.

      Jim, you could benefit by doing some objective research. The CDC considers person UNVACCINATED, if any of the following are true: 1. The injury or death is within 14 days of the first or second dose. 2. The injury or death is after 90 days (as the benefits–if any disappear after about 90 days or are greatly diminished.

      According to multiple studies, deaths are up worldwide in direct proportion to the percentage of folks that are “vaccinated.” As for underreporting at VAERS, that is estimated to be off by a factor of 31 to 100. That means ALL deaths and injuries have to be multiplied by 31 (J. Rose), 41 (S. Kirsh), or 100 (Pilgram/Harvard study). This is consistent with I’ve found by talking to funeral directors. One in London said deaths are up about 50 percent over 2019. Scott Davison (One America, largest life insurance company in Indiana), says deaths are up 40 percent for age group 18-64 and several local funeral director all say deaths are off the charts, about fifty percent increase in All-Cause-Mortality. By the way, there was NO change in deaths over-all in America from 2019-2020. You can believe what you want, but you are incorrect. The evidence is there and it is unbelievable. But this is a free country and I think it’s fine that people have differences of opinion. So call some local funeral homes, give NO opinion and with an innocuous tone to your voice, say, you’re a researcher and want to know what have been the changes–if any between deaths in 2021 and 2019. Don’t call anyone in Amish Country, (Eastern PA, and Western, NY), they “got rid of “Covid” by the end of May, 2020 or about 20 months ago. I know EXACTLY how they did it….do you?

        You also have to remember when severe injuries and deaths began to happen during the short run trials, rather than record that as data those people were simply dropped from the study and their data was simply not present in the FDA results.

The best evidence says the vaccine is worse than natural infection and even if it wasnt what a ridiculous argument you have presented..the vaccine cant prevent transmission or infection! – the most vaccinated countries have the highest covid rates so with your reasoning we should take a shot that will increase our risk of myocarditis by 133% for a vaccine that can’t prevent the infection that will apparently give us worse myocarditis?

    It is not true that benefits of vaccination are higher that damage. Please, see article below and other similar. It is not only due to molecular mimicry though. There are more reasons for that as immune system shifts to more damaging immune cells like Th17 after toxic exposure to toxic metals, mold, diesel exhaust and pesticides. I had autoimmune thyroiditis – Hashimoto outbreak after child delivery due to hormone shift and stress and the second time after installation of mercury fillings. But I believe I had symptoms from childhood though sub-clinical and nobody told me about that. Childhood vaccine and stress contributed to that for sure. My son has autoimmune cardiomyopathy from herpes infection with health failure but had vaccine because he believed it can protect him. It caused the second outbreak and more symptoms. We try all kind of alternative treatments as doctors don`t offer anything except drugs for herpes.
    He is doing better now and even started to travel. He needs more joy not only treatments and supplements. Heart is the home of joy, if there is no joy it is getting sick. Some doctors are even refused to accept him as they know that prognosis is bad. But you should not look at prognosis, you should start searching for better ways to heal not only drugs. He started researching alternative therapies himself even if he was not interested in them earlier. Good luck to you! I hope that forum can help us to get more information about all possibilities. We should have more discussions about that. See article here https://www.nature.com/articles/cmi2017151

    I understand the folks that say “stop the poison death shots” which is a noble sentiment. However, if people want to get them, they have the right to do so. I’ve been able to convince the people whom I care about – my wife, my adult children, and a few close friends – to avoid them, as I have. Therefore, we have zero risk of any adverse reactions to these injections. That is all I care about. When acquaintances start dying, I’ll make note of the fact, feel a little sad for a brief moment, then continue on with my life. There are not that many people whom I truly care about, certainly none of those who condemn us for refusing to be injected. Those deaths will not warrant even a passing nod.

Three Weeks to the day, after first vaccine, my Healthy husband, an Airline Pilot, who had just completed his flight physicals with a clean bill of health, dropped dead in the middle of the afternoon for no apparent reason except that his heart exploded! He had had no heart problems. To think, that afternoon, he’d planned to take the grandchildren up in our bi-plane for rides! Can you imagine?

    NNV = Number Needed to Vaccinate
    to prevent infection, transmission, death.

    NNV > 1. Not everyone vaccinated doesn’t get COVID . & Not everyone vaccine free get COVID.

    NNV for flu shot is about 60.
    60 flu shot will prevent 1 flu.
    Which would you rather get?
    NNV also depends on exposure.
    In nursing home NNV could be as low as 12. With a good match.

    2019 their was a major measles out break.
    1249 case
    119 hospitalized.
    0 died.
    CDC clames 95 % US are vaccinated.
    That leaves 16.5 million unvaccinated.
    The chance a vaccine free person would get measles in a major out break is 1 in 13,210.
    CDC recommend 2 💉💉.
    And the vaccine last 86 years.
    If every year was a major out break
    It would take 307 💉 to save 1 case.
    And 3,000 💉 to save 1 hospitalized.
    And no death.
    Which would you rather get
    3,000 💉 or 1 hospitalized?
    Or you can get 💉 instead of 💉💉.

    How about Polio?
    No cases in the last 20 years.
    Polio is spread by unsanitary water in under develop country.
    0 bennifits for US.
    How do we know if the Polio vaccine worked?
    How do we know how many we need?
    How do we know the best age to get 💉💉💉?
