@Rocketman: There is no correlation between vaccine rates and death rates.
If COVID was such a threat if you're not vaccinated, with only 50% of the population vaccinated, you should still see similar levels and outbreaks amongst the unvaccinated. You don't.
You don't see that due to natural immunity in the majority of the population. Even the CDC says that natural immunity develops automatically (https://www.cdc.gov/vaccines/vac-gen/immunity-types.htm)
There have been recent studies indicating at least 50-75% (depending on the model) of people currently not vaccinated have been exposed and may have developed natural immunity.
The fact that Canada has problems dealing with people getting sick has more to say about their hospitals than about the disease. In the US, except for NYC state-run hospital (which were overran because Cuomo refused to pay for care at empty privately owned public hospitals), no hospitals were overrun. In Canada, hospitals are overrun on a regular day as people often wait up to a year to get critical care (https://www.fraserinstitute.org/studies/waiting-your-turn-wait-times-for-health-care-in-canada-2019)
