(Express Photo: Amit Chakravarty) The overall risk of heart inflammation (myopericarditis) following Covid-19 vaccination is very low, affecting 18 people per million vaccine doses, a study in The Lancet Respiratory Medicine has found. The researchers found no statistically significant difference between the incidence of myopericarditis following Covid-19 vaccination and other vaccinations (56 per million).
THE CONDITION: Myopericarditis is a condition that causes inflammation of the heart muscle and, in some cases, severe permanent heart damage. It is most often caused by viruses, but in rare instances can also occur after vaccination .
DATABASE: The researchers looked at more than 400 million doses from global databses, and analysed more than 20 studies with reported incidences of myopericarditis following any type of vaccination between January 1947 and December 2021.
