Fatal Anorexia caused by COVID-19 vaccination

A 90-year old woman weighting 40.5kg (89.3 pounds) develops anorexia after the first dose of the COVID-19 Pfizer vaccine (0.3 ml containing 30μg of mRNA).

Vital records showed abrupt increases in the body temperature, systolic and diastolic blood pressure, and pulse, and decreases in the intake of meals and drinks and body weight. The patient lost 1/4 of her body weight by the time of death 28 weeks after the COVID-19 vaccination. The patient also experienced hallucinations and decreased mental status, as well as decreased SpO2 levels. One month before death, her status was changed from level 2 (partial assistance) to level 5 (bedridden).  Before the injection her vitals were steady with exception of short-termed changes because of minor illnesses.

Vital records restricted to the last 6 months (180 days; Figure 2) show the pre-injection horizontal regression line, large + level change for temperature, pressures, and pulse, and – level change for meals and drinks, post-injection – regression line. The R-squared value (coefficient of determination) suggested that the injection strongly influenced and affected all the observed changes. 

The data were collected from April 2019 to August 2021 and included the day of the vaccine, 2 June 2021. The records include timetable records of three daily meals (shown as main dish 6/10, side dish 9/10, where 10/10 meant complete meal, while 0/10 meant no meal), drinks (ml), body temperature, blood pressure, pulse, saturation of percutaneous oxygen (SpO2), urination, defecation, and physical and medical examinations.
