The truth about myocarditis and Covid vaccines Two facts — both of which are widely misinterpreted Fact One mRNA jabs can cause myocarditis, an extremely rare complication that causes inflammation of the heart muscle) Fact two That heart-related deaths are massively above levels seen pre-pandemic. Conflating the two is not only incorrect, but irresponsible. Swiss study Myocardial Injury after COVID-19 mRNA-1273 Booster Vaccination mRNA-1273 vaccine-associated myocardial injury was adjudicated in 22 participants (2.8%). One in 35 recipients (2.8%) had vaccine-associated myocardial injury Matched controls, elevated high-sensitivity cardiac troponin T concentration Significantly higher in post vaccination group p leaa thAN N N = 777 per group Thai study Cardiovascular Manifestation of the BNT162b2 mRNA COVID-19 Vaccine in Adolescents After BNT162b2, 2nd dose, Thai adolescents, aged 13–18 years, n = 314 Most common cardiovascular signs and symptoms Tachycardia (%) Shortness of breath (%) Palpitation (%) Chest pain (%) Hypertension (%) One participant could have more than one sign and/or symptom Cardiovascular manifestations were found in % of patients Seven participants (%) exhibited at least one elevated cardiac biomarker Myopericarditis was confirmed in one patient after vaccination. Two patients had suspected pericarditis Four patients had suspected subclinical myocarditis The clinical presentation of myopericarditis after vaccination was usually mild and temporary, with all cases fully recovering within 14 days. Hence, adolescents receiving mRNA vaccines should be monitored for cardiovascular side effects. Israeli study A prospective study on myocardial injury after BNT162b2 mRNA COVID-19 fourth dose vaccination in healthy persons Incidence of myocardial injury after fourth dose BNT162b2 mRNA vaccine (Pfizer-BioNTech) N = 324 High-sensitivity cardiac troponin (hs-cTn) Vaccine-related myocardial injury was defined as hs-cTn elevation above the 99th percentile upper reference limit, and more than 50% increase from baseline measurement. Reported vaccine-related adverse reactions Fatigue in 39 (%) Myalgia in 32 (%) Sore throat in 21 (%) Headache in 18 (5.5%) Fever ≥38°C in 16 (%) Chest pain in 12 (3.7%) Palpitations in 7 (%) Shortness of breath in one (0.3%) Vaccine-related myocardial injury in two (%) The two cases had mild or no symptoms and no clinical sequela. US study Autopsy Proven Fatal COVID-19 Vaccine-Induced Myocarditis All autopsy studies, vaccine-induced myocarditis as a possible cause of death Most cases had symptoms consistent with myocarditis prior to death We established that all 28 deaths were causally linked to COVID-19 vaccination by independent adjudication.
