Experts ask: How can such a defective vaccine be used?

Five renowned chemistry professors wrote an open letter to BioNTech founder Şahin in January 2022. The letter questions the quality assurance, the ingredients and side effects of the Comirnaty vaccine, as well as the additives contained in the mRNA injections. These haven’t been approved for use in humans because they are carcinogenic according to animal studies. The description of a grayish substance that indicates contamination is just as questionable. They want clarity as to why serious side effects occur with some batches and whether there is an independent monitoring of this. So far, BioNTech has not responded to the signatories.
Jörg Matysik, professor of analytical chemistry at the University of Leipzig, says, "As chemists, we are not sure that this product should be used as a mass vaccine at this time."
