IMPORTANT ANNOUNCEMENT
Next, a microscopic, observational and merely descriptive study of the test sample is presented.
Definitive identification of the dominant material in the sample requires further fractionation and specific spectroscopic analysis to characterize the structure of the material.
Essentially all they did is a microscopic analysis of a single sample of Pfizer vaccine. I wouldn't put a lot of stock in this single study.
I do believe I read somewhere that another similar, also Spanish, study came up with the same result with a different sample.
They make no claim more than what they observed, with a number of images from high-powered microscopes included.
It is limited, but it is more than nothing — which is what Big Pharma or the EUA-granting government organizations have given us. Most likely this is a massive global test with different shots including different materials, dosages, controls, etc.
I put just as much stock in the study as they claim, since they don’t seem to go beyond what they have verified. And yes, the link is just to one, in a sense, preliminary study.
But I don’t go with those on this thread claiming that there is no such study, obviously.
