Moderna’s COVID-19 Vaccine 4 Times More Likely to Cause Heart Inflammation Than Pfizer’s: Study
“Vaccination with [Moderna’s vaccine] was associated with a significantly increased risk of myocarditis or myopericarditis in the Danish population,” and the rate was “threefold to fourfold higher” with the Moderna vaccine compared to the Pfizer-BioNTech vaccine, authors said in the study, which spanned almost 85 percent of Danes, or 4.9 million people aged 12 and older.
The increased risk of myocarditis or myopericarditis with the Moderna vaccine was “primarily driven by an increased risk among individuals aged 12-39 years,” said the researchers, from Denmark’s Statens Serum Institute.”
