I believe the best information is in the graphs in this paper, combined with thinking about behavior of individuals and of restrictions that are or are not observed.

The virus levels in the infected person are just as high in day 1 to 4 of the illness whether they are vaccinated or not. The virus levels then fall off in the vaccinated person.
Now, who spreads it more, that's hard to say.Â

Now, who spreads it more, that's hard to say.Â
- The vaccinated person isn't likely to have high levels over the longer run. Â
- The vaccinated person is less likely to spread it by coughing, but then is less likely to recognize they are sick and so won't isolate. Â
- The vaccinated person is less likely to wear masks or avoid crowds or to avoid shouting or singing or other ways it might spread.
