The essentials
- Before this study, there was no prospective data on post-vaccination myocardial lesions during vaccination with an RNA vaccine. Only the most serious myocarditis hospitalized has been reported, mainly affecting men under the age of 18.
- The actual incidence of post-vaccination myocardial lesions is 2.8% vs 0.0035% myocarditis in retrospective studies
- Myocardial lesions affect women more, contrary to what is described in previous studies.
- The possibility of repeated doses of vaccine to maintain effective vaccination coverage should lead to great caution regarding possible repeated myocardial lesions and their impacts on possible cardiovascular complications.
