Heart inflammation is a “very rare” side-effect of the Covid vaccines made by Pfizer and Moderna, according to regulators in Europe.

The European Medicines Agency said the side-effects were more common in younger men.

The medicines safety body said the benefits of Covid vaccines continue to far outweigh any risks.

But doctors and patients have been advised to be aware of the symptoms of heart inflammation, BBC reported.

These include chest pain, a feeling of breathlessness and a pounding or fluttering heartbeat. Anyone with these symptoms should see a doctor.

Two conditions were linked to the vaccines – inflammation of the heart muscle itself, known as myocarditis, and inflammation of the fluid-filled sac the heart sits in, known as pericarditis.

The EMA analysis of cases found:

Pfizer-BioNTech – 145 cases of myocarditis and 138 cases of pericarditis out of 177m doses given

Moderna – 19 case of myocarditis and 19 cases of pericarditis out of 20 million doses given

Five people died. The review said they were all either elderly or had other health conditions.
