Phase 3 of the Pfizer trials was completed in January 2021. Approximately 40% of the trial participants were age 56 or over.

Not sure what this trial is. But I followed the phase 3 trial from phizer which was dated for completion in 2023 and everyone was under 60. So is this another trial or are they changing data?
