It would not be surprising if, at initial assessment when a PCR would typically be done, the unvaccinated and partially or full vaccinated carry the same amount of virus. The vaccine is not a forcefield. But it would also be important to know about the replication of virus in people, and it would be surprising if virus replicated to a similar degree in all, and that is probably a more important driver of transmissibility than initial infection load.
It also misses the point that those who develop symptoms over-represent the unvaccinated.
