How so? No matter how you get the spike proteins in you (virus, mRNA vaccine, or traditional vax using the spike protein as target) the preferential targeting of the virus for immune system cells, combined with the properties being exhibited by the spike protein, means that the immune system isn't able to properly develop the immunity you should be getting from infection or from vaccination. If a different target from the virus was chosen, perhaps it'd be a different story, but going for the spike protein without having a fuller understanding of what it does in our cells has made the vaccines for SARS-CoV-2 questionable given the findings in this paper.
