A non-pregnant 84-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 intramuscular on 13Apr2021 (at the age of 84-year-old) as single dose for COVID-19 immunisation.

Concomitant medications included regular prescribed medications for HTN, HLD, DM2 (drugs unspecified). No other vaccines prior to four weeks. Known allergies were unknown. No COVID prior to vaccination. Covid test post vaccination in May2021 was negative. The patient had no acute issues prior to her 1st COVID vaccine. In Apr2021, the started experiencing progressive weakness and poor appetite to the point of hardly being able to walk. The patient saw her primary doctor who ran some blood work and noticed she was dehydrated with mild elevated liver enzymes and WBC count. The patient was admitted to the hospital (for 21 days) for IV fluids and was on oral antibiotics. The patient started having some SOB and scans done indicated possible lung infection. The patient was switched to IV meropenem which did not help. The doctors also noted some lesions on her liver and a small mass in her lung (no biopsy was done cause she declined) which they said were suspicious for cancer. The patient then suffered a large ischemic stroke and she passed about a week later. The patient was feeling well before her vaccine and everything started to go downhill after her vaccine.

The patient died on 27May2021 due to ischemic stroke and infection. An autopsy was not performed.  No follow-up attempts are possible; information about lot/batch number cannot be obtained.; Sender's Comments: Based on the available information  and known product profile, the causal relationship between the reported suspicion on malignancy and BNT162B2 use is  unrelated while the causal relationship between the remaining events and the use of BNT162B2 cannot be fully excluded. There is limited information available which precludes a more meaningful assessment. However, the underlying conditions and the age of the patient maybe risk factors.
