They shouldn't tweak cell genetics. I'm not saying they definitely don't but that's not the stated purpose. The mRNA ends up in the cell but like virus genetic material it shouldn't generally end up in the host's genetic material (although virus dna has done this in the past and a good chunk of human dna is from viruses).
