The development of messenger ribonucleic acid (mRNA) vaccines has revolutionized the field of preventive medicine. These came into the spotlight during the COVID-19 pandemic. Despite the fact that vaccines are broadly safe, some rare, life-threatening side effects have been reported in the recent past, and myocarditis is one of them. We present a case of COVID-19 mRNA vaccine-induced myocarditis in a young male. Three days after receiving the third dose of the BNT-162b2 mRNA vaccine for COVID-19, he presented to the emergency department after experiencing palpitations. He was admitted to the hospital due to raised cardiac enzymes and a concerning echocardiogram. Magnetic resonance imaging the following day revealed myocarditis. There have been multiple cases of myocarditis reported in the literature owing to the COVID-19 mRNA vaccine. This case stands out because of the presence of regional wall motion anomalies in the echocardiogram, which is an unusual finding in patients with myocarditis. We recommend keeping a low threshold for investigating young patients presenting with cardiovascular symptoms who have received a recent COVID-19 mRNA vaccine.
