In reply to Andreas, there are four types of COVID-19 vaccines on the market and/or in development: Whole Virus, Protein Subunit, Viral Vector, and Nucleic Acid (RNA AND DNA). Some of them try to smuggle the antigen into the body, others use the body’s own cells to make the viral antigen.
The Whole Virus vaccines are the ones that use either a weakened form of the virus that can still replicate without causing the illness or viruses whose genetic material has been destroyed so they cannot replicate, but can still trigger an immune response.

All four types of vaccines are trying to achieve the same thing: immunity to the coronavirus, and some might also be able to stop transmission. They do so by stimulating an immune response to an antigen, a molecule found on the virus. My understanding is that all of them have the potential to trigger an inflammatory reaction.
Since the principal Whole Virus vaccines are manufactured in China (the Sinovac vaccine already in circulation within China and Indonesia, which was tested among volunteers in Brazil, Indonesia and Turkey, plus Chinese Sinopharm vaccines in the pipeline), I am pretty sure that the problems Dr. Druey has been informed about are associated with the other types of vaccines that are being administered here in the United States and in Europe, which are NOT of the Whole Virus kind.
