Ireland’s medicines’ watchdog has been notified of nine cases of certain heart conditions that have been detected following the administration of the Pfizer and Moderna vaccines.
The conditions are called myocarditis and pericarditis which cause inflammation on the heart’s tissue.
According to the Health Products Regulatory Authority (HPRA), six cases were reported after the first dose of the vaccine while three were reported following the second dose.
As of June 9th, there has been approximately 2 million doses of these vaccines administered.
A representative of HPRA stated that in a number of the cases, there were possible alternative explanations other than vaccines.
The European Medicines Agency (EMA) was instructed by the Pharmacovigilance Risk Assessment Committee (PRAC) to add the conditions as a new side effect of mRNA vaccines.
The cases, which were predominantly reported in young men, occurred more in the second dose of the vaccine.
Four of the cases that occurred in the state were women while five were men.
The median age was 56 years old which ranged from 38 to 81.
In the majority of cases, individuals fully recovered while some had ongoing symptoms.
In Europe, there has been 164 cases of myocarditis and 157 cases of pericarditis reported amongst people who received the Pfizer and Moderna vaccines.
As of May 31st, there has been 200 million doses of these vaccines administered throughout Europe which means these cases are serious but rare.
Symptoms of these conditions include breathlessness, palpitations and chest pain.
However, the EMA has assured that the benefits of the vaccine outweigh the side effects.
