The narrative is that you take the vax then it enters the cells and causes you to produce spike proteins then you make antibodies and then the proteins quickly are broken down by the body, the vax never goes into the cell nucleus to change dna. The vax is supposed to only be there from days to weeks, also broken down and cleared from the body. Not permanently there in the cell. WEF is testing something PERMANENT (blood markers post vax) or needs test data results for the vax experiment to see CHANGES in your other numbers of blood markers. Blood markers are used to find the signs of disease in blood and markers can be stable and in normal ranges over time or can change quickly enough that some people have to test frequently for specific blood markers to make their health decisions (tests for blood sugar, WBC, cholesterol, tumors, inflammation, clotting...) This article says they can look at blood markers (pre-vax) to see who is more likely to have reactions to a flu vaccine https://acemind.net/flu-vaccine-predicting-side-effects-using-blood-markers "Blood markers would make it possible to identify people ..." Most important to learn is WHAT marker is WEF testing? Then we'd know if it was a marker normally there before the vax or only there after and in what numbers: "The WEF failed to elaborate exactly on what substance in an individual’s blood would indicate their vaccination status."
