Although the Pfizer/BioNTech and Moderna vaccines have been linked to incidents of mild heart inflammation, European and UK health organizations believe the benefits exceed the dangers.

In a tiny percentage of persons who received the immunizations, myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining around the heart) have been reported.

Both the European Medicines Agency (EMA) and the UK's Medicines and Healthcare products Regulatory Agency (MHRA) say that younger men were most likely to see the complication, especially after their second jab.

The European Medicines Agency (EMA) and the Medicines and Healthcare Products Regulatory Agency (MHRA) are advising healthcare professionals and the general public to watch for signs of heart inflammation in patients who have received the two vaccines.

Chest pain, shortness of breath, palpitations, and an irregular heartbeat are all symptoms.

Anyone who has been vaccinated and is experiencing these symptoms should seek "urgent medical assistance," according to the MHRA.

The instances were most common in men under the age of 40, and they occurred within 10 days following a second dose.

The majority of patients who had myocarditis and pericarditis healed fast with standard myocarditis and pericarditis therapies as well as rest.

Myocarditis and pericarditis are now listed as side effects of the vaccines by the EMA.
