It is Pfizer's own document “Cumulative Analysis of Post-authorization Adverse Event Reports” reporting on the fatalities.
Attributed? They attribute 1223 “case outcomes” as “fatal.” Please read Pfizer's PDF. Page 7.
They didn't say any were caused by the vaccine.
Do you understand what this report is? It's every adverse medical event someone had at some point following a shot.
Look at Appendix 1. It's 9.5 single-spaced pages listing all of the types of events that were reported. Things like tounge biting and white nipple sign.
Humans have all kinds of medical issues every day but that doesn't mean they were caused by the shot.
The relevant question is were there more deaths in this group of people than you would expect in a demographically similar population of the unvaccinated?
No one, and certainly not Pfizer, have presented any evidence that there were.
