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.
This is going to spread like wild-fire over the web, but let’s take it easy.
Even if the Spanish report (it looks like a ppt-presentation in the original Spanish format)is correct, and we take their figure of ca 750 ng / vial (ie 750 x 10^-9 g) this is far less than any in vivo toxic dose.
According to the paper below the in vivo toxic dose (intra venously) is larger than 1 mg/kg body weight (mice, rats). Even if we take the smallest figure that would mean a total dose of 75 mg for a normal human adult. That is a dose which is 100 000 larger than the amount of graphene in the vaccine sample (which according to the paper was actually 6 doses).

Correct, there was another article done about 2 weeks ago, that graphene oxide was in their vaccine, but can’t remember where it was published.
