Key result
Four young male patients developed mild, uncomplicated myocarditis or pericarditis detected by cardiac MRI shortly after receiving various SARS-CoV-2 vaccines.
Why the study?
Serious adverse events associated with new SARS-CoV-2 vaccines are of high interest to the public and public health during the worldwide mass immunization campaign.
Case Report (n=4)
No
SARS-CoV-2 vaccination may be temporally associated with mild cardiac inflammation (myocarditis/pericarditis) as detected by cardiac MRI, though the overall benefits of vaccination continue to outweigh the risks.
Case reports link myocarditis to SARS-CoV-2 vaccines on MRI; leaves open causality and incidence in larger populations.
Serious adverse events associated with new vaccines targeting SARS-CoV-2 are of high interest to the public and to public health as a worldwide mass immunization campaign has been initiated to contain the ongoing COVID-19 pandemic. We describe a series of 4 individuals with signs of a myocarditis/pericarditis according to cardiac MRI results in temporal association with currently in the European Union authorized SARS-CoV-2 vaccines. We found mild abnormal MRI results independent of the type of SARS-CoV-2 vaccine. There is a need of continuing monitoring outcomes of myocarditis cases after COVID-19 vaccination as recently published cases suggest an uncomplicated short-term course whereas the long-term implications are not yet known but taking the available evidence into account the benefits of using COVID-19 vaccines still clearly outweigh the risks.

Jahnke et al. (2022) conducted a case report in Myocarditis and pericarditis (n=4). SARS-CoV-2 vaccination was evaluated on Cardiac MRI findings of myocarditis or pericarditis. Four young male patients developed mild, uncomplicated myocarditis or pericarditis detected by cardiac MRI shortly after receiving various SARS-CoV-2 vaccines.
