Heart Damage: mRNA Vaccines (Pfizer/Moderna)

Side effects, including those that are serious or life-threatening, are still being learned about. The United States Centers for Disease Control and Prevention (CDC) announced on June 11th 2021, that an Emergency Meeting would be held to discuss reports of inflammation of the heart resulting from use of the Pfizer and Moderna vaccines in young males 16 to 24 years of age (Six months after the vaccines were authorized under an emergency use). Only now is this association being recognized.

There are many reasons why it is difficult to identify serious side effects that are rarer or that occur only over a longer period of time or in a specific population group or sex. These difficulties are due to many problems with the fast-tracked rapid distribution:

  • no long-term studies available yet
  • not closely-following everyone taking the vaccines
  • no long-term animal studies
  • the ‘control/placebo’ groups from the original trial were unblinded and offered the vaccine
  • under-reporting of Adverse events
  • the ‘safe & effective’ marketing campaign leading to many not connecting symptoms to the vaccines
  • the health regulators, media, governments, and pharmaceutical war on ‘vaccine hesitancy’
  • each country having a different reporting method
  • many different groups of people left out of the original clinical trials (so only finding in the ‘real world’ the potential problems that weren’t identified during the initial trials)
  • the trials were too small
  • the trials were setup to favour a higher efficacy end-goal point and not focused on safety

THEY KNEW, and didn’t tell you!

Canada Myocarditis Study: 1 in every 1000 injections

Canada Myocarditis Study: 1 in every 1000 injections

A new scientific study has been published based on scientific research conducted in Canada which has concluded that the Covid-19 Vaccines are actually causing 1 in every 1,000 people to suffer myocarditis, rather than the 4.3 cases per million doses administered claimed by the UK Medicine Regulator and the Chief Medical Officer, Professor Chris Whitty.

This means that if every chid over the age of 12; estimated to be 3 million children, take up the offer of the Pfizer mRNA Covid-19 vaccine, at least 3,000 of them could suffer myocarditis which causes inflammation of the heart and can lead to cardiac arrest, and knock years off life expectancy.

The findings were discovered in a study conducted by the University of Ottawa Heart Institute in Canada, which was published to medRxiv on September 16th 2021.

The study was conducted following several reports of a possible link between mRNA Covid-19 vaccines, produced by both Pfizer and Moderna, and the subsequent development of myocarditis and pericarditis.

Myocarditis is inflammation of the heart muscle, whilst Pericarditis is inflammation of the protective sacs surrounding the heart. Both are serious conditions due to the fact the heart muscle cannot regenerate. Myocarditis can permanently damage the heart muscle, and if left untreated this can cause the heart muscle to be unable to pump blood effectively. Unfortunately the condition can also lead to heart failure.

Myocarditis and pericarditis happen very rarely in the general (unvaccinated) population, and it is estimated that in the UK there are about 6 new cases of myocarditis per 100,000 patients per year and about 10 new cases of pericarditis per 100,000 patients per year.

The scientists who conducted the study looked at propesctive cases of muocarditis and pericarditis that occurred between June 1st and July 31st 2021. They identified patients by admission and discharge diagnosis which included myocarditis and / or pericarditis, who had received either the Pfizer or Moderna mRNA injection within one month prior to onset of symptoms.

Thirty-two patients were identified between June 1st and July 31st, twenty-nine of which were males. The average age of the patients was 33 years-old, however, the age of the patients ranged from 18 – 65 years-old. Eighteen patients were diagnosed with myocarditis, 2 patients were diagnosed with pericarditis, and twelve patients were diagnosed a suffering both myocarditis and pericarditis at the same time.

”A recent study found a 4-fold increased risk of post-vaccination myocarditis in those who had previously been infected with SARS-CoV-2″ Is this true? We don’t know – it’s based on observational-data. To know it’s not true, we need a large trial, that proves the vaccines reduce hospitalization more than they cause myocarditis.

“I’m a little concerned that we’re talking about a vaccine that was derived from a viral sequence, that is now over a year and half old, and that strain is actually not circulating anymore, so when you’re trying to immunobridge an immune response against the vaccine to clinical benefit, you’re looking at clinical effecicy that was derived from a different set of circulating strain, so I’m having a little trouble as to how we can actually estimate the likelihood of ongoing protection, from what is now a new set of circulating strains going forward”

Melbourne Bulldogs Vaccination Webinar - All Speakers should be charged with crimes against humanity

Knowing this information has been sent out by NSW Health on advice from ATAGI, and reported as a known risk on the CDC Website, explained in most recent FDA Committee Meeting (1 in 5000) as “Risks outweigh Benefits“, with a HIGHER RISK in young males who get mRNA vaccines (Pfizer/Moderna), you would expect the Melbourne Vaccination Webinar to address and inform the parents, right? WRONG.

Sent to All Victorian Parents to answer questions
and encourage those in the West to get Vaccinated.

“Play On | Victoria, Let’s Get Vaccinated!”

Sep 1, 2021 05:30 PM Canberra, Melbourne, Sydney

Ignored questions about known issues with myocarditis and pericarditis – focused on dangers of COVID, the importance of Vaccinations, and addressed AstraZeneca’s blood clot – no information about Pfizer.

  • Didn’t bring up these known heart problems or inform about it at all
  • Constantly reminded to get their information from ‘trusted sources’ (Health.gov.au, CDC, WHO) and not listen to others – well, this would imply that they too are getting their information from these sites and it gives the misguided impression to these parents that by listening to them, they are also getting the information from these official sites.
  • All of these sites report the known Myocarditis risk – but the speakers deliberately avoided the topic, and avoided questions that asked them to please address it, only focusing on questions that would encourage vaccination.
  • These Parents won’t look if they think the speakers – a doctor and a nurse are being transparent with you about the risks. The general public won’t look if they already think they are getting the latest and most accurate safety information. Parents don’t understand the risk, and those who are getting these conditions are saying they were never told this could happen.
  • The speakers only answered questions in relation to COVID and that “Clotting” has a low risk (references to AstraZeneca, not Pfizer). When answering questions in relation to covid, they exaggerated the risks with children – frightening the parents unnecessarily into believing that children should get vaccinated.
  • Are the people in charge of our health even looking at the research and CDC warnings, or are they being ‘given’ what to present? Or are they so focused on vaccines that they literally cannot see any data that may cause ‘vaccine hesitancy’? Is this your idea of an information session? Is this your idea of “Informed Consent”?

I DESPERATELY sent all the official links to them live while they were talking - AND THEY IGNORED ME

Sending questions to speakers throughout the webinar trying to get them to address these known issues:

(all questions were ignored)

Referencing these CDC Reports:

“vaccinated people who have previously had Covid-19 illness there is up to 112% increase of requiring hospitalisation due to severe adverse reactions.”


“associated with an increased risk of severe side effects leading to hospital care”


Alfred Health Vaccine Information Session on Myocarditis

Upon looking for any more recent information sessions, I found that Alfred Health has created a new video on the 20th of September, which looked promising – they had a slide in their presentation regarding the Myocarditis & Pericarditis risks (by Ex Victorian Chief Health Officer Prof Allen Cheng and paediatrician A/Prof Nigel Crawford), but unfortunately they skimped right past it:


At 15min mark – “we have seen some cases, although they’re rare, of both pericarditis (which is the lining of your heart), and myocarditis (which is the heart itself), and this link to an animation we put together, can sort of talk through it in a visual way what that means and what we’re doing to monitor it, so people can watch that later if that interests

That’s the information session for you “here’s a link of an animation”?

If anyone actually paused to get the URL of the link he referred to, the first link does not lead to the video, but the Vimeo one is here: Animation: https://vimeo.com/594092904

If myocarditis or pericarditis is suspected, rapid assessment by a GP or Cardiologist is important.

In the animation, it states people with known heart conditions can still ‘safely get a vaccine’?

And states if anyone experiences these symptoms: chest pain, pain with breathing, shortness of breath, sweating, or heart palpitations within a few days to a few weeks of the vaccine, should seek immediate medical attention.

Myopericarditis, Endocarditis and Heart Inflammation Symptoms

Heart Inflammation: also known as Endocarditis, Myocarditis, Pericarditis

On that page, it says:

Signs and Symptoms

If a virus causes your heart inflammation, you may have a cough, runny nose, or gastrointestinal symptoms a few weeks before symptoms of your heart inflammation. The signs and symptoms of heart inflammation are different depending on the type of heart inflammation you have.


  • Fever and chills
  • New or worsening heart murmur
  • Blood in urine
  • Spleen that is larger than normal
  • Abdominal pain
  • Chest pain
  • Cough, with or without the presence of blood
  • Loss of appetite and weight loss
  • Muscle, joint, and back pain
  • Night sweats
  • Pain where an infected cardiac device is located
  • Shortness of breath
  • Skin changes, which can occur with endocarditis. These may be painful red or purple bumps, or painless flat red spots on places such as the palms of your hands or soles of your feet, or tiny reddish purple spots from broken blood vessels.


  • Chest pain and discomfort
  • Heart palpitations
  • Fainting
  • Shortness of breath
  • Fatigue
  • Abdominal pain
  • Exercise intolerance, or no longer being able to exercise
  • Fever
  • Loss of appetite
  • Swelling of feet or legs
  • Weakness


  • Chest pain. Chest pain from pericarditis typically feels sharp, gets worse with breathing, and feels better with sitting up and leaning forward.
  • Fast heartbeat
  • Fever
  • Shortness of breath

Lifelong use of Drugs may be necessary and do not exercise (they say)

Prevent compilations or repeat events

You may need to take some medicines throughout your lifetime. If prescribed, lifelong use of antifungals for fungal endocarditis or colchicine for pericarditis may lower your risk of a repeat event.

Repeat events of heart inflammation can happen. People with endocarditis have a lifelong risk. Repeat events of pericarditis are common in the first 18 months after treatment. People with myocarditis are at risk for a repeat event for years after the first occurrence.

Do not exercise until given permission by your doctor. For myocarditis, this may be several months or longer after treatment.

Medical Conditions That Can Keep You from Joining the Military

Dr Josef Thoma explains what a diagnosis of myocarditis really means

The Inflammation of the Heart Muscle Caused by SARS Cov 2 Vaccine

Feb 23, 2022 By now, everyone has heard that the COVID vaccines cause myocarditis, particularly in the young; however, the significance is downplayed in the media and even in officious medical publications. In the 11-minute video, Josef Thoma MD/PhD, a general practitioner from Berlin, explains what a diagnosis of myocarditis really means: even if it has apparently healed, the patient is left with a lifelong risk of sudden cardiac death, and often also with diminished stamina and quality of life.

Thoma presents some recent observations on autopsy materials from vaccine victims, made by professors of pathology Burkhardt and Lange, which drive home he serious nature of vaccine-induced myocarditis. He ends with an appeal to us to protect our children.

WHY is this happening? (and Open Letters)

Why is this happening?

Researches haven’t yet found why mRNA vaccines are causing myocarditis and say it’s still a mystery“, but doctors and virologists who aren’t getting the spotlight are saying that because it is happening in both those who get COVID as well as those who take the vaccines (like other side-effects), that it is the spike protein itself that could be causing the damage.

Doctors for COVID Ethics
Doctors and scientists write open letter warning about safety concerns of COVID-19 experimental vaccines

Canadian COVID Care Alliance

“We thought the spike protein was a great target antigen, we never knew the spike protein itself was a toxin and was a pathogenic protein. So by vaccinating people we are inadvertently inoculating them with a toxin.”

“What has been discovered by the scientific community is the spike protein on its own is almost entirely responsible for the damage to the cardiovascular system if it gets into circulation”.

Page 14 & Page 15 (Slide #9) – American Data https://www.skirsch.com/covid/Deaths.pdf
The COVID-19 vaccines generate myocarditis/pericarditis at 860 times the rate of the typical flu
vaccine in a year

Classified as a rare disease, myocarditis is unlike most cardiovascular conditions in that it often affects younger, healthier people, enlarging and weakening the heart by making it work harder to pump oxygen and blood through the body. It can prove fatal, though most cases resolve on their own without recurrence.
