An 80,000-page cache of Pfizer-BioNTech COVID-19 vaccine documents released by the U.S. Food and Drug Administration (FDA) sheds light on Pfizer’s extensive vaccine trials in Argentina, including the unusually large size of the trials and the story of a trial participant whose vaccine reaction was “disappeared.”
The case of Augusto Roux in Argentina suggests that in at least one instance, a trial participant whose symptoms were determined to be connected to the COVID-19 vaccine was later listed, in official records, as having experienced adverse events that were not related to the vaccination.
Vaccine trials in Argentina also appear to have glossed over adverse events suffered by other trial participants, and the potential connection between the adverse events and the vaccine.
The FDA on May 2 released the latest cache of documents, which pertain to the Emergency Use Authorization of Pfizer’s vaccine, as part of a court-ordered disclosure schedule stemming from an expedited Freedom of Information Act request filed in August 2021.
