At minute 11:36, Dr. Delgado mentions the name of Dr. Andreas Noack. Noack was not a medical doctor, but a German doctor of chemistry who last lived in Austria and was also an engineer and activated carbon specialist. He died mysteriously a few days after his last video on November 23, 2021, which you can read about here.
Dr. Andreas Noack did not examine the vaccines himself, but re-evaluated the findings of Dr. Campra/Madrid. In his opinion, it would not be graphene oxide but graphene hydroxide a.k.a. reduced graphene oxide. In the blood of the vaccinated, there would be razor-sharp nanoparticles that would slice the mirror-smooth inner walls (endothelium) of the blood vessels. This would be consistent with what pathologists have found in all patients
This would also explain why so many athletes die as a result of the vaccinations, because the faster the blood flows, the more damage the razor blades can do.
