14 Year Old Girl’s Death in Japan Officially Linked to Pfizer’s Comirnaty

From a study produced by Tokushima University.

A 14-year-old Japanese girl received a third dose of the BNT1262b2 mRNA COVID-19 vaccine/Pfizer (Comirnaty®) on 10th August 2022. She had a history of orthostatic dysregulation but she was healthy by nature and was active in her middle school athletic team. The day after vaccination, she developed a fever of 37.9 °C, which resolved by the same evening.

Her sister, who had slept with her that night, reported that she woke up briefly because she was having difficulty in breathing, talked with her sister, and went to bed soon after. The following morning, her mother noticed that she was not breathing and had a pale appearance, and she immediately called an ambulance. The patient was in cardiopulmonary arrest when the ambulance crew arrived at their house and attempts to administer advanced life support were unsuccessful.

She died 45 hours after the third vaccination. After the first dose of vaccine on 12th September 2021, she had arm pain without fever. The day after the second dose on 3rd October 2021, she missed school because she had a fever of less than 38 °C. All three vaccines were made by Pfizer. An autopsy was performed the following day to evaluate the cause of sudden death.

An autopsy diagnosis of vaccine-related multiple-organ inflammation was made based on the absence of bacterial or viral infection, lack of a past medical history suggestive of autoimmune disease, no allergic reaction, and no drug exposure other than the vaccine. Myopericarditis is a form of multiple-organ inflammation. Although pneumonia is involved, pneumonia alone is rarely a cause of sudden death, and the presence of erythrocyte-laden macrophages as well as congestive edema of the lungs on histology suggested signs of heart failure from the previous day. Although the extent of inflammation was relatively narrow, the presence of foci centered on the atria and breathlessness are the findings that raise the suspicion of heart failure several hours before death. This led to the diagnosis that the cause of death was vaccine-related myopericarditis, which led to severe arrhythmias and progressive heart failure.

The Japanese government has received over 2,000 reports of Covid-19 vaccine related deaths since the shots were introduced in February, 2021.
