Heart Cases and mRNA Vaccine Connection Identified

The US Centers for Disease Control and Prevention (CDC) vaccine advisory committee stated today 'there’s a likely connection between rare cases of myocarditis or pericarditis and mRNA vaccines.'

In a presentation delivered on June 23, 2021, by Grace M. Lee, M.D., MPH, and Robert H. Hopkins, Jr., M.D., with the Vaccine Safety Technical working group, these cardiology risks, although rare, were confirmed higher in young males following the second dose of an mRNA vaccine.

There have been approximately 323 confirmed cases of myocarditis or pericarditis found in vaccinated adults under 30 in the USA, reported the CDC on June 14, 2021.

Myocarditis is inflammation of the heart muscle, and pericarditis is inflammation of the heart's outer lining. In both cases, the body’s immune system causes inflammation in response to an infection or some other trigger, says the CDC.

This CDC data is similar to the finding in the UK by the Medicines & Healthcare products Regulatory Agency. As of June 2, 2021, this UK agency had received 39 reports of myocarditis and 27 reports of pericarditis following use of an mRNA vaccine, as well as one report each of viral pericarditis and Streptococcal endocarditis.
