A group of researchers are calling into question Pfizer’s and BioNTech’s early trial data on its original COVID-19 vaccine after a forensic analysis revealed significant inconsistencies between data in the companies’ six-month interim report and publications authored by Pfizer/BioNTech trial site administrators.
The preprint, published on Sept. 4, showed trial subjects vaccinated with Pfizer’s COVID-19 vaccine experienced a 3.7 times increase in cardiovascular deaths compared to placebo controls—a “significant adverse event signal” not disclosed by Pfizer when the vaccine was authorized for emergency use. In addition, the analysis found numerous instances where Pfizer/BioNTech attributed potential vaccine-associated deaths to other causes and undermined vaccine safety data.
