As part of a series of targeted micro-reports based on the Pfizer 5.3.6 Post Marketing Experience document released in March 2022 due to a FOIA request by Aaron Siri, this document is a report on the first 90 days following the roll-out of the EUA Pfizer vaccine in the UK, USA and other countries.

More than one in five patients (20%), who received the vaccine who had a stroke, died. 50% of patients who had a stroke after the vaccine had it within the first 2 days.

The War Room/DailyClout Pfizer Documents Analysis Project Post-Marketing Team created the following Stroke System Organ Class (SOC) Review from data in Pfizer document 5.3.6 Cumulative Analysis of Post-Authorization Adverse Event Reports of PF-07302048 (BNT162B2) Received Through 28-FEB-2021 (a.k.a., “5.3.6“). The stroke category comprises the diagnoses of strokes attributed to either obstruction of blood flow through arteries to areas of the brain or due to bleeding around or into the brain. Additionally, in this adverse event category, Pfizer included syndromes of diffuse venous clotting in and around the brain and clotting in the venous pools within the skull (cerebral venous sinus thrombosis and cavernous sinus thrombosis). Arterial obstruction blocks oxygen-rich blood delivery, whereas the venous thrombosis prevents drainage of blood from within the head.

Within the stroke data set, there are 275 patients with 300 different events reported; and 20% of the stroke events were fatal.

It is important to note that the Adverse Events in the 5.3.6 document were reported to Pfizer for only a 90-day period starting on December 1, 2020, the date of the United Kingdom’s public rollout of Pfizer’s COVID-19 experimental mRNA “vaccine” product.
