People across all age brackets are at a higher risk of death from heart inflammation after COVID-19 vaccination compared with the typical occurrence of myocarditis death. Researchers in Japan analyzed deaths caused by myocarditis where the condition was detected within 28 days of vaccination. They ultimately identified 38 deaths that 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 electrocardiogram, according to a report from The Epoch Times.
The researchers then compared their data with the death from myocarditis rate from the general population before the pandemic, from 2017 through 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,” said Dr. Sintaroo Watanabe of the Japan Marine United Corporation and Dr. Rokuro Hama of the Japan Institute of Pharmacovigilance.
“However, not only in young adults, but also in the middle aged (40s) and in the elderly and overall vaccinated, increased risk of myocarditis death is associated with vaccination even without consideration of healthy vaccinee effect,” the researchers added.
The “healthy vacinee effect” refers to how injections are sometimes not distributed to people with poor health, a factor that can muddy the visible impact of adverse effects.
According to Watanabe and Hama, even their lowest estimates of the effect found that the risk of COVID-19 vaccination on myocarditis death would be at least four times higher than the unadjusted mortality risk. “Based on the results of this study, it is necessary to inform public about [sic] that the risk of serious myocarditis including death may be far more serious than the risk reported before and that it occurs not only in young persons but also in elderly,” they said.
The study was published as a preprint ahead of peer review on medRvix (pdf), The Epoch Times reported.
Limitations of the paper included the diagnosis of myocarditis death after vaccination being based on a doctor’s diagnosis.
