Moderna’s Covid mRNA vaccine is significantly more dangerous than Pfizer’s when it comes to myocarditis and pericarditis. This is shown by recent studies and the CDC also recognizes this. However, the vaccine will continue to be distributed.
In July there was already one in the journal JAMA Cardiology published study linking “acute chest pain” in male American soldiers to mRNA vaccination. The researchers found that the pain was caused by myocarditis and pericarditis. These are two different types of heart infections. As we now know, these are rare but dangerous side effects of mRNA vaccines.
About six weeks later, the published Washington Post leaked data from a Canadian study. This study claims that the risk of these types of dangerous side effects (which are most common in younger men) was significantly higher in patients who received the Moderna vaccine than in patients who received the Pfizer vaccine.
How much more dangerous is the Moderna vaccination than the Pfizer vaccination?
The preliminary data leaked to the WaPo show that the risk of myocarditis with the Moderna vaccination could be up to 2.5 times higher. However, the risk with the Pfizer vaccines should not be ignored either. We’re talking about serious heart disease, after all. These remain lifelong.
A day after the FDA overrode its own advisors, by approving the Moderna vaccine and the J&J booster vaccination for virtually all American adults (while also providing guidelines for the combination of booster vaccines), a CDC advisory panel met on Thursday and, after reviewing all the data on the Safety and effectiveness finally admitted, that previous warnings about the excessive dangers associated with Moderna vaccination have been confirmed.
The data clearly speak against Moderna
As the slide below shows, the rates of rare heart risks (myocarditis / pericarditis) in 18- to 39-year-olds are higher for the Moderna vaccine than for the Pfizer vaccination. However, there are risks with both vaccinations. It is the younger patients (who need the vaccines the least) who are most affected by the side effects.

The CDC Advisory Committee presentation claims that most post-vaccination cases of heart infections “are generally mild and symptoms resolve quickly”. But keep in mind that this is the case in adult patients under 40 who are the least at risk for Covid. Unless, for example, they have a weakened immune system. Even if you are obese or have other problems that make you particularly vulnerable, Covid can be a hazard.
Despite all of this, the CDC’s advisory panel allows so-called “booster shots”. Even if this increases the risk of this dangerous inflammation of the heart muscles even further.
It is worth remembering that Sweden, Denmark, Finland and Iceland are watching the younger citizens stop giving Moderna vaccines. Why? Because they have an increased risk of such heart diseases from the experimental vaccines. And once the heart muscle is damaged, it does not regenerate. So these mRNA vaccines may produce thousands, if not millions, of future heart patients. Is that what Big Pharma wants? The healthcare business is generating tens of billions in profits.
