Our World in Data features a bunch of different ways to look at vaccination data. The most commonly displayed curves are the cumulative ones, showing vaccinations over time:
These curves convey a sense of progress, as they rise over time.
But there’s another way of displaying this data to tell a different story, which looks at how many vaccinations were done on any given week. This way of displaying the data allows us to see when vaccine enthusiasm was at its peak. Again, looking at Canada:
The numbers correspond, as far as I can determine, the first dose rollout, second dose rollout (with some overlap between these), the first booster rollout, and the second booster rollout. The size of each mountain tells about how many people got vaccinated in that particular rollout. We can see that there is a pretty significant reduction in the size of each successive rollout.
There is more complexity in this - probably some people received boosters in rollout number 2, however, the central point is that vaccine enthusiasm in the Canadian population has gotten pretty low by August 2022.
So where does Canada sit, relative to other countries?
I invite you to do your own analyses of this. Most countries’ vaccine enthusiasm dropped off at the end of 2021 - most of Western Europe for example, and the United States:
Notice how the big mountains of 2021 disappear.
It is almost as though boosters stopped having appeal in a huge swath of the world, simultaneously, over the winter of 2021/2022…
