Acute myocarditis and rhabdomyositis after coronavirus disease 2019 messenger RNA vaccination and intensive training: a case report
We suggest that strenuous training associated with skeletal muscle damage, together with the strong immunostimulatory effect of messenger RNA vaccination, may lead to autoimmune rhabdomyositis that potentially cross-reacts with the myocardium. Athletes should be aware of the potential danger of heavy training in close proximity to vaccination or acute infections.
