You can see the infection numbers among vaccinated people in Alberta here:
https://www.alberta.ca/stats/covid-1...ccine-outcomes
At the bottom of the page are charts showing infections, hospitalizations, and deaths broken down by age and vaccination level.
Of all the fully-vaccinated deaths, only 4 were people under the age of 75 (2 between 40 and 59 and 2 between 60 and 74). All 4 of them were diagnosed within 20 days of receiving their second shot, so they were likely exposed within the 14 day window.
The charts in the middle of the page show the vaccination status of people in the hospital. Right now, 72% of the people in the hospital, but not in ICU, are unvaccinated and 90% of the people in ICU are unvaccinated.
