There was data from Denmark, Germany, and a third place a couple of weeks ago where the share of Omikron infections in the vaccinated was 10-15% points greater than the share in the total population (like 70% vacc/total vs 80% vacc/infected). I've checked one of the original sources (country's public health agency) and it confirmed the claim. To be fair, that could be because there are more restrictions for the unvax'd versus the vax'd.
