I'm guessing most of those look at viral loads in break throughs. But I'm not sure that is quite as relevant as the viral load that typically results upon exposure, i.e. my guess is that viral load in breakthrough cases looks different than in non-breakthrough cases. I think this study tries to get at this problem. https://spiral.imperial.ac.uk/bitstream/10044/1/90800/2/react1_r13_final_preprint_final.pdf https://spiral.imperial.ac.uk/bitstream/10044/1/90800/2/reac...
