Do you know Polish? The translation was total shit. It's hard to say what he was really saying (my friend is in Poland, but can't be bothered to do a word for word translation).

Totally agree on the sample size. Also, Pfizer crap is made in various different sub-contractor factories. They run non-consecutive alphanumerical identification batch codes, making them hard to pinpoint to a origin.

One would need several mfg batches from various diff. factories to really make anything conclusive.

And yeah, I agree, there is a possibility of saline only Vials. As for the actual cause of that, that remains to be determined.
