Ah, the, "clinical batches," versus, "production batches." This is true. The story at the time was that they were shipping production batches and would use their lab scale production facility which creates the juice for clinical trials for internal consumption. The optic they tried to create was that this was another production unit for vaccine and Pfizer would use those without drawing from the mass production pool. Seemed sketch at the time because it is. If they wouldn't shoot the juice off the line then nobody should.
