So I did the back of the envelope math.
Alberta has a total population of 4,436,258 and has 213,635 covid cases. that gives you 4.82% of natural immunization.
Rolling 7 day average of vaccination is around 40,000 to 42,000 per day.
If you can get that 7 day average to 44,000 per day, that would get you 1% of the total population per day.
Currently Alberta is 37.4% vaccinated, with 1 shot, of the total population.
So add 4.82% and 37.4% = 42.22% round down to 42%
33 days or less to reach 75% of first shot and you have more than enough supply to knock a lot of second shots off too.
That's best case scenario and couple of guys that I have been following on twitter seems to have much better calculations.
Bottom line is if Alberta is going to calculate with the natural immunization then I would put it at 5%
