In table S4 (supplementary material), there are two cases of death attributed to COVID-19 in the placebo case, and none to BNT162b2. There are other unrelated causes of death in the cohort. Also the causes of death are from dose 1 to unblinding, so there is the possibility that antibodies would not have ramped up entirely. It was a study to ascertain safety; that it did not cause more deaths.
From: Friam <[email protected]> On Behalf Of Pieter Steenekamp Sent: Tuesday, September 14, 2021 11:25 PM To: The Friday Morning Applied Complexity Coffee Group <[email protected]> Subject: [FRIAM] Could this possibly be true? In the Phizer report "Six Month Safety and Efficacy of the BNT162b2 mRNA COVID-19 Vaccine" (https://www.medrxiv.org/content/10.1101/2021.07.28.21261159v1.full.pdf) , I picked up the following: "During the blinded, controlled period, 15 BNT162b2 and 14 placebo recipients died" Does this mean the Phizer vaccine did not result in fewer total deaths in the vaccinated group compared to the placebo unvaccinated group? I sort of can't believe this, I obviously miss something. But of course, there are clear benefits in that the reported vaccine efficacy was 91.3%
