[Asia Economy Reporter Hwang Sumi] A study has found that the risk of myocarditis is higher when infected with COVID-19 than after vaccination.

On the 1st (local time), according to the US economic media CNBC, the US Centers for Disease Control and Prevention (CDC) announced research results showing that the risk of myocarditis, pericarditis, and multisystem inflammatory syndrome in children (MIS-C) after COVID-19 infection is higher than after receiving messenger RNA (mRNA) vaccines such as Pfizer and Moderna.

Previously, mRNA COVID-19 vaccines were reported to cause side effects such as myocarditis and pericarditis, especially in teenagers and young adults.

This study was conducted by examining the medical records of more than 15 million males and females aged 5 and older from 40 US healthcare organizations over one year starting January last year.

As a result, even among teenagers aged 12 to 17, the risk of myocarditis and pericarditis was higher after COVID-19 infection than after vaccination. In this age group, at least 50 out of 100,000 contracted myocarditis and pericarditis after COVID-19 infection, whereas after the second vaccine dose, the number decreased to at least 22 per 100,000.

Looking at the overall risk of heart disease, the CDC reported that the risk was 5.6 times higher after COVID-19 infection compared to after the second vaccine dose. Compared to the first vaccine dose, it was 69 times higher.

However, the CDC added that cases of such heart diseases occurring after both COVID-19 vaccination and infection were rare.
