Inflammation of the heart may take two forms. These are firstly myocarditis of the heart muscle, and secondly pericarditis of the outer heart lining. John Hopkins Medicine confirms coronavirus infection may inflame blood vessels in veins. However, today we are more interested in vaccinations for COVID-19 and inflammation of the heart.
Where Does This Concern Spring From?
News Medical Science placed a post on March 6, 2022. This pointed to new research appearing in science journal Medrxiv. The work investigated concerns relating to COVID-19 vaccination and inflammation of the heart.
The medical scientists analyzed reports from 14 studies of patients who experienced medical complications after vaccination. Their headline findings are as follows although there are margins of error:
PFIZER
1… Myocarditis after second Pfizer occurred in under 20 cases per million among females of any age, and also children aged 5-11.
2… However, it may have appeared in 25 to 82 male adults per million between18-39, but there are some doubts.
3… The third vaccine shot associated with less than 20 cases per million among adults aged 40 years and over.
MODERNA
1… Moderna is likely to be associated with a higher incidence of myocarditis in males and females aged 18-29 years.
2… This also apparently applies to males aged 18-39 years. In older adults, the effects appear minimal.
Countering Inflammation of the Heart After COVID-19 Vaccination
The researchers conclude these risks could reduce by spacing doses between 31 and 56 days. They believed this could be most beneficial among young males between the ages of 18-29.
Over 90% of myocarditis cases after vaccination were reported in males aged 20-29 years. Although the youngest patient was 12 and the oldest 56 years old. Mortality was under 1%, with most patients discharging within 2 to 4 days.
