A warning has been issued after the European Medicines Agency (EMA) found a possible link between the Pfizer and Moderna vaccines and heart disease.
Although rare, the EMA’s safety committee Pharmacovigilance Risk Assessment Committee (PRAC) is recommending that myocarditis and pericarditis be listed as new side effects of mRNA vaccines.
The single-dose Johnson & Johnson vaccine is also an area for concern in regards to people who have a history of capillary leak syndrome according to the EMA, who have advised against its use in said people.
Myocarditis is a condition where the heart muscle becomes inflamed while pericarditis is an inflammation of the pericardium which surrounds the heart and holds it in place.
A review was conducted on people in the European Economic Area (EEA) who received the Comirnaty Pfizer vaccine and found 145 cases of myocarditis and 138 cases of pericarditis.
An additional 19 cases of each condition were also found amongst people who received the Spikevax Moderna vaccine.
In regards to the Johnson & Johnson vaccine, a review found three cases of capillary leak syndrome in vaccinated individuals with two subsequently dying. One of the individuals had a history of this condition.
As of May 31st, there have been 177 million doses of the Comiranty Pfizer vaccine and 20 million doses of the Spikevax Moderna vaccine administered in the EEA.
Over 18 million doses of the Johnson & Johnson vaccine have also been administered worldwide as of June 21st which implies that these side effects, although serious, are rare.
