Risk of getting myocarditis is higher for Covid-19 than vaccine – CDC

According to a new study by the Centers for Disease Control and Prevention (CDC), the risk of getting myocarditis is far higher post-Covid infection than it is after receiving the Covid-19 vaccine.

Myocarditis is a condition that causes inflammation around the heart and has recently been linked to the Pfizer and Moderna Covid-19 vaccines.


The CDC study analysed hospital records from 1.5 million patients with Covid-19 and 35 million who were not infected.

The authors of the study wrote, “Overall, myocarditis was uncommon among persons with and without Covid-19; however, Covid-19 was significantly associated with an increased risk for myocarditis, with risk varying by age group,”.

The study found that the risk was at its highest for those under 16 years old, who saw a 37-fold increased risk of myocarditis when compared to people who didn’t have the virus.


Although the exact link between myocarditis and Covid-19 is not fully understood, it’s estimated that it might be related to viral infection of the heart or multisystem inflammatory syndrome.

A paper which was published by Israeli researchers last week in the New England Journal of Medicine found that mRNA vaccines increased the risk of myocarditis three-fold, while Covid-19 increased the risk 18-fold.


Five to 12-year-olds are now the age group with the highest Covid incidence rate

According to Deputy CMO Dr. Ronan Glynn, children aged five to 12 years old currently have the highest Covid-19 incidence rate.
