How to distinguish the blood of “vaccinated” from “unvaccinated”?

Update May 2024:

Ever since SafeBlood and Safereproduction were launched, we have been looking for an analysis that would allow us to determine whether blood for transfusion or a sperm donation comes from a vaccinated or unvaccinated donor. Until now, the selection of our donors has been based solely on the trust that our members will correctly declare their vaccination status. But now we finally have a blood analysis that allows us to determine the following:

1. Residues of any Covid19 vaccines
2. The presence of spike proteins
3. Whether the functionality of your RNA and DNA is disrupted or damaged

For me, the latter is the biggest sensation, because it shows whether there is a need for therapy and whether the mRNA injection has actually resulted in a significant impairment of your genetic material. We know that different batch numbers, e.g. in the Pfizer vaccinations, triggered very different side effects; from “placebo” with zero effect, to immediate death in the most dangerous batches.

Everything about the Covid19 Vaccine Residual Analysis can be found here.

Status before May 2024 and general information:

Prof. Dr. Stefan W. Hockertz answered this question for me:

The only thing that comes to my mind is the detection of the gene product. Vaccinated individuals should carry a significant amount of the spike protein permanently. This may be detected in this ELISA test specific for the spike protein IgG. https://www.coronavirus-diagnostik.de/antikoerpertestsysteme-fuer-covid-19.html . Of course, this also includes the acutely ill persons – but they should not donate blood in this condition either.
The direct detection of the spike protein would be, funnily enough, the hypersensitive PCR. A “vaccinated” person should, in contrast to a diseased person, express the spike protein much longer, and without any symptoms. The actual asymptomatic ill person a la Drosten 😊 . This would also be a distinguishing feature based on this PCR, which is highly praised for other purposes. Quite exciting: Excluded from blood donation would definitely be spike protein PCR positive symptomless people who express the spike not due to infection but due to gene therapy – and this continuously over a period exceeding the normal pathogenesis (ca 5 days). You might also throw a few “long-covid” people into the wrong potty, but it is better to be over-precise than to have a “vaccinated” person as a donor.
