“620% surge” is what happens when you use relative risk to make a rare event sound enormous. The study found 163 myocarditis cases among about 4.45 million vaccinated people, versus 21 among about 4.44 million historical controls. That produced an adjusted hazard ratio of 7.2 — hence the frightening “620% increase.” The actual incidence was about: 0.28 vs 0.04 cases per 10,000 person-years. And the authors were not “discovering” myocarditis. They deliberately used myocarditis and pericarditis as positive controls because those vaccine-associated signals were already known. The paper’s main conclusion? Most autoimmune connective-tissue diseases were not increased after mRNA vaccination. So yes, myocarditis is a real rare adverse effect. But converting 0.28 cases per 10,000 person-years into “MYOCARDITIS SURGED 620%” is how you sell fear to people who never ask for the denominator.

A study of more than 6.3 million younger people found no increased risk of sudden death after COVID vaccination. So where does “7 standard deviations above baseline” come from? Not from CDC. Not from a peer-reviewed pediatric sudden-death study. It comes from a private analysis that chose its own baseline, coding assumptions, and statistical model, then wrapped the result in the authority of “CDC data.” That is not the same thing as CDC concluding childhood sudden cardiac death rose seven standard deviations after vaccination. If the claim is real, show the methods: the ICD codes, baseline years, age adjustment, denominator, infection adjustment, and vaccinated-versus-unvaccinated comparison. Until then, “7 sigma” is decoration. The large population data do not show the signal being claimed.
