The Pfizer and Moderna vaccines are effectively identical. The only differences between them are that they use slightly different lipids that make up the nanoparticles and the salts solutions used as a buffer (keeps pH neutral) and anti-clumping.

The salts are a trivial difference. They are all commonly used.

The lipids are most likely a trivial difference, though even if not, they would almost certainly not have any different effect on any specific organ. If there is a meaningful difference between the lipids and our ability to metabolize them, then the difference would almost certainly be shown systemically, and not in any particular tissue (maybe the liver? I have seen no evidence for that).

The organ specific issues are almost certainly due to the spike protein and the size and type of technology that is the nanoparticles. In this respect both the P/M vaccines are identical. That is why when we look at the data, the reactions are virtually identical (statistically) across the board.
