People of all ages are at higher risk of death from heart inflammation after COVID-19 vaccination compared with the typical occurrence of myocarditis death, according to a new study. Researchers in Japan analyzed deaths caused by myocarditis, a form of heart inflammation, where the myocarditis set in within 28 days of vaccination.
Thirty-eight deaths fit the definition, about half of which were diagnosed by autopsy and or biopsy, with the others being determined through tools such as blood tests and electrocardiograms. Researchers then took the vaccinated mortality rate and compared it with the death from myocarditis rate from the general population before the pandemic, in the years 2017 to 2019.
“Using the disclosed data by the Japanese government, we observed increased myocarditis mortality rate ratio in the SARS-CoV-2 vaccinated population compared with general population during three years pre-COVID-19 pandemic era, especially in young adults,” the researchers, Dr. Sintaroo Watanabe of the Japan Marine United Corporation and Dr. Rokuro Hama of the Japan Institute of Pharmacovigilance, said.
