It would be great if the government would give us some stats from the Delta wave about breakthrough infections and the vaccine mix the people had.
That would go a long way towards lifting travel restrictions for those with mixed doses (or not if the numbers don't look good).

Also, I don't know when they added this, but I just noticed it yesterday, the government stats now breakdown cases over the last 120 days (back to early May) by age range, vaccine status, and whether or not the person has a pre-existing condition.

The big takeaway is if you're under 60 and fully-vaccinated, your chances of requiring treatment in a hospital (or worse) are extremely low, especially if you don't have any underlying conditions.
In the last 120 days, 127 people under the age of 40 in Alberta have spent time in the ICU with COVID. 1 of them was partially vaccinated. None of them were fully-vaccinated.
57 people under 60 have died from COVID in the last 120 days, 5 were partially vaccinated and 2 were fully vaccinated. 4 people under 40 have died in the last 120 days from COVID, they were all unvaccinated.
