False Alarm: Claims of Mass Extinction Linked to COVID-19 Vaccines Debunked

A concerning claim circulating online alleges that a renowned US clinic predicted millions of deaths due to COVID-19 vaccinations within the next five years. this assertion, widely shared on platforms like Facebook, attempts to link COVID-19 vaccines to a surge in myocarditis cases and subsequent fatalities. However, this claim is demonstrably false.
Fact check: The Cleveland Clinic‘s Position
Investigations reveal that the claim originated from an article on the website “Slaynews”, a site known for spreading disinformation, as repeatedly documented by the German Press Agency (here and here). A spokesperson for the Cleveland Clinic confirmed to the DPA that the clinic made no such statement. “Recent claims that suggest that Covid-19 vaccination will lead to myocarditis and mass extinction are wrong and are not a scientific basis,” the spokesperson stated.
Understanding Myocarditis
Myocarditis, an inflammation of the heart muscle, can be caused by various factors, including viral infections like influenza and, yes, COVID-19. While rare cases of myocarditis have been observed following mRNA COVID-19 vaccination (Pfizer-Biontech and Moderna), the Cleveland clinic reports that most individuals recover quickly with appropriate treatment.Crucially, scientific literature, including research cited by the National Institutes of Health, demonstrates that the risk of myocarditis is significantly higher after contracting the coronavirus itself than after receiving a vaccine.
The US Centers for Disease Control and Prevention (CDC) continues to recommend COVID-19 vaccinations, acknowledging the rare risk of myocarditis but emphasizing the far greater risks associated with infection.
Shifting Data and Misleading Data
It’s vital to note that information evolves. An archived version of the Cleveland Clinic’s myocarditis webpage from March 23, 2025 (view archive) initially presented survival rates without specific reference to vaccination. The site has since been updated to reflect the nuanced understanding of myocarditis risk in the context of vaccination. “Slaynews” deliberately presented a distorted picture, exaggerating the potential mortality associated with vaccine-related myocarditis.
Infection as a Greater Risk
The German Center for cardiovascular research (DZHK) emphasizes that most cases of cardiac muscle inflammation are triggered by viral infections. While myocarditis can rarely occur after influenza vaccinations or mRNA vaccines, the incidence is considerably lower than that associated with a COVID-19 infection. A study by the French drug agency ANSM further supports this, demonstrating fewer complications in patients experiencing myocarditis related to vaccination compared to those with myocarditis from other causes.
