      ). During a recent deployment to Afghanistan, we had a similar case of smallpox vaccine-mediated myopericarditis that presented as an acute ST-segment elevation myocardial infarction (MI) on electrocardiogram (ECG). A 27-year-old man presented to our military emergency department in Afghanistan complaining of acute onset of crushing substernal chest pain and dyspnea. His symptoms had occurred intermittently for the past 3 days but became persistent and severe 30 min prior to arrival. Of note, he had arrived in Afghanistan from the United States (US) 1 week prior. He denied cough, fever, vomiting, or radiation of pain, and the pain was not positional in nature. He had not experienced any prior history of similar symptoms. His past medical history was significant only for a smallpox immunization he received 2 weeks prior to presentation.
