Our vaccinated rate per 100 people is average to below-average for western developed countries. How am I using the term "rate" incorrectly?
Yes, but what does that mean? You can always find an average. What's the dispersion and where does Canada fall within that?
If you're in a class of 20 and 18 people score 75%, one scores 50% and one scores 100%, then you would be average if you score 75% but it doesn't mean a whole hell of a lot, does it?
You need to contextualize these things. The vaccine rollout isn't a failure by any stretch of the imagination. A few weeks or even a couple months behind will be meaningless in the grand scheme.
