Swiss Prospective Cohort Study Demonstrates Frequent Heart Damage after Moderna mRNA-1273 Booster
Vaccination Far Greater Threat to Heart than SARS-CoV-2 Infection
By Peter A. McCullough, MD, MPH
Adjudicated myocarditis was very rare with SARS-CoV-2 infection in 2020 before mRNA vaccines and there were no cases resulting in myocarditis-specific hospitalization and death. As a result the NCAA Big Ten athletic league and the US military gave up screening for myocarditis. In 2020, about ~30% of the student population contracted the illness before vaccines. These programs were ill-informed and poorly timed since the real risk of myocarditis was coming with the COVID-19 vaccines at the end of 2020.
Cross-sectional studies of sick COVID-19 inpatients found ~30% (depending on how many were tested) had abnormal troponin values but this is common for all forms of ICU illness including bacterial sepsis. For example, Lala et al found 89% of all COVID-19 inpatients had troponin testing as part of ICU care. Using the Abbott Architect method (Abbott, Abbott Park, Illinois), 99th percentile for normal 0.028 ng/ml, health system cutoff of 0.03 ng/ml, Lala reported 36% of patients were positive. The American College of Cardiology among other organizations used these and other data to incorrectly declare “myocarditis is far more common with SARS-CoV-2 infection than with vaccines.” They could have made the same claim with bacterial or urinary tract sepsis since there was no adjudication with ECG, echocardiography, MRI, and physician review. Additionally, sick inpatients cannot be compared with free-living well people forced to show up at a vaccination center.
After sparse cases, outpatient myocarditis screening programs after COVID-19 illness shut down in 2020. This was bad timing since just a few months later in June, 2021 the US FDA posted a warning that mRNA vaccines cause myocarditis and requested that Pfizer and Moderna conduct studies to determine the frequency and clinical outcomes of this complication. After posting intention to do the studies on ClinicalTrials.Gov, neither company produced a study result. If the Big Ten and US military kept their screening programs open, they would have found an explosion of cases after vaccination.
