Same, but I bet there just hasn't been enough time to get data. It's been 3 years since the first vaccines, we probably only have 2 years of people getting vaccinated then getting diagnosed, then you have to wait for the follow-on effects to show

You won't ever get a good estimate as a practical matter because the population that hasn't gotten it post-vaccine by now are not a good reference population for comparison wrt having "average" health behaviors.
