The overall risk of myocarditis – inflammation of the heart muscle – is substantially higher immediately after being infected with COVID-19 than it is in the weeks following vaccination for the coronavirus, a large new study in England shows.
The detailed analysis of nearly 43 million people was published Monday in the American Heart Association journal Circulation.
"We found that across this large dataset, the entire COVID-19-vaccinated population of England during an important 12-month period of the pandemic when the COVID-19 vaccines first became available, the risk of myocarditis following COVID-19 vaccination was quite small compared to the risk of myocarditis after COVID-19 infection," the study's lead author, Martina Patone, said in a news release. She is a statistician at the University of Oxford Nuffield Department of Primary Health Care Sciences in England.
"This analysis provides important information that may help guide public health vaccine campaigns, particularly since COVID-19 vaccination has expanded in many parts of the world to include children as young as 6 months old," Patone said.
Myocarditis is the inflammation of the middle layer of the heart muscle wall, known as the myocardium. It is uncommon and typically triggered by a viral infection.
