The vaccines do not produce anti-bodies to the virus, they produce anti bodies to the protein spikes of the virus. Covid anti-bodies found in a person will be from encountering the virus naturally, not from the vaccine. With successful vaccine administration those anti bodies will shrink to zero.
It is not a traditional ‘whole virus’ vaccine. So there are no ‘whole virus’ anti bodies -which is what the PCR test tests for.
Your post makes a lot of sense, but it leads to even more difficult questions, at least for the authors of the study.
For example, how on earth, given a useful sample size, did they come up with a “younger” sample group that tested 97.8 % positive for antibodies to the “whole virus”? Did the entire group get the J &J vaccine on the sly?
