Good catch. And since the sample was not taken in a lab setting, who knows what kind of environmental contamination occurred. So, yeah. I think this is a case of someone who first formed a conclusion, then went looking for evidence.
This could easily be tested. Obtain N samples of vaccinated and unvaccinated blood, label and randomize. Prepare without knowing which is which. Then compare all blood and see if anyone can match the results. But that would be science anathema to “functional” quacks. Even though such a study, if confirmed, would bring lots of business to these blood charlatans.
