You can't use US as an example.
CDC estimated there were 114 million Covid infections in US (
https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burden.html).
That means 34% of its population had natural immunity (and they paid a very high price for this natural immunity).
Canada has much much less infection (and also much much less deaths from Covid).
So Canada needs a much higher vaccination percentage to match the immunity.
This much quoted number is just disinformation spread by anti-vaxxers.
This number is from VAERS, as it was mandatory to report any deaths after covid vaccinations REGARDLESS of the cause of death.
CDC investigated 4,000+ death reports up to May 10, and they found none was associated with the Covid vaccines.
