Initially classified as generic “sudden cardiac deaths,” patients were all under 45 and took mRNA vaccines. Researchers suspect U.S. passive monitoring hides deaths picked up by Korean active monitoring.
Nearly 200 U.S. colleges still require vaccination against COVID-19 as further research documents the disproportionate risk of post-mRNA vaccination heart problems in young males, who face low risk from SARS-CoV-2 itself.
The requirement continue amid research that appears to show adverse events associated with COVID vaccination.
Researchers studying South Korea’s national reporting system found that among roughly 44 million residents 12 and older who received at least one vaccine dose through December 2021, males 12-17 and 18-29 had the highest vaccine-related myocarditis rates, at 5.29 and 2.93 per 100,000, respectively.
Severe cases formed a surprisingly high proportion of VRM cases (19.8%), Chonnam National University Medical School faculty and COVID vaccine adverse events investigators for the Korea Disease Control and Prevention Agency wrote in the European Society of Cardiology’s journal.
Among severe cases, nine-in-10 included ICU admission, three-in-eight fulminant myocarditis that is marked by “severe and sudden onset” and high mortality rate, and 22% each death and “extracorporeal membrane oxygenation therapy.”
