Other ideas as I struggle to understand the current state of affairs: maybe the vaccine is really effective at preventing transmission, but only for some period, say 1 month to 6 months after vaccination? Maybe people in Canada received their vaccines between January and June of 2021, so maybe with boosters every 6 months, transmission would be under control?

That's more or less it. Also

- it might be that two shots 6 months apart are more effective. i.e. skipping the 2nd shot in the 3 shot series would be fine.

- it might be that a nasal vaccine would be more effective than an injected one. We just don't have one of those yet.
