Pfizer’s own 6 month study showed that deaths were balanced between BNT162b2 (Pfizer vaccine) and placebo groups. 15 died in the Pfizer group and 14 died in the placebo group. After the crossover where the placebo group was given the Pfizer vaccine, another 3 died in the Pfizer group and 2 died in the now vaccinated placebo group.
Investigators don’t consider a single death in the Pfizer group to be related to the vaccine, thus the final score is vaccine at 0 deaths vs. placebo at 16 deaths, proving the vaccine prevented deaths.
Table S4 is buried in a separate supplemental material PDF that’s not linked in the study and you won’t find unless you know what keywords to type into a search engine.
