[Myocardial infarction after influenza vaccination]

Influenza is a common disease in the population. Influenza vaccination is performed routinely and is usually well tolerated. Minor local or systemic side effects like fever and myalgia are described. Rarely there are more severe adverse events. Systemic vasculitis has been reported in some cases. In this case we report on a female patient with secondary vasculitis and myocardial infarction after influenza vaccination. The patient received cortisol and recovered. The literature about influenza vaccination, its side effects and recommendations about vaccination in patients with coronary artery disease is reviewed.
