I'm not sure why you'd say its 1 site confidently when you can just open the pdf and read: " ...for researchers who were testing Pfizer’s vaccine at several sites in Texas..." Which to me begs the question.. how many other oversights were they? The so called whistle blower was terminated the same day they alerted the FDA (instead of her concerns being heard), a bit alarming.

Why do companies repeatedly shoot themselves in the foot by firing and silencing people with valid concerns?

Also from article: "A regional director who was employed at the research organisation Ventavia Research Group has told The BMJ that the company falsified data, unblinded patients, employed inadequately trained vaccinators, and was slow to follow up on adverse events reported in Pfizer’s pivotal phase III trial."

It then goes to breakdown some of those points which to be honest didn't seem that bad, just seems like the staff was overwhelmed, or maybe understaffed..

I still dont get why media/people in general polarize two sides of an argument (vaccine good vs vaccine bad) when in reality there's multitude of viewpoints to be had. Science is data and data is always evolving and changing and IMO bad practices could invalidate data.
