Tozinameran: Myocarditis.

A man in his 40s developed myocarditis after receiving the tozinameran (Pfizer BioNTech) COVID-19 vaccine. He experienced fever the day after vaccination and then suddenly lost consciousness and was admitted to the emergency department. Despite medical interventions, he suffered irreversible brain damage and multiple organ failure, leading to his death on the ninth day of admission. Autopsy results confirmed myocarditis as a result of the vaccine, and other contributing factors to his death included hypoxic encephalopathy, arrhythmia, and multiple organ failure.
