Canada is about to pass Israel for First-dose vaccination percentage (63%) of total population.
Other than some micro-nations, no country has hit 70% (of population, not eligible adults).
The obvious difference is that Canada only has 8% fully vaccinated. Other countries have hit a ceiling around 65% of people getting one dose. The US only has 51% of the total population with one dose.
I think all efforts in Canada should be focused on second doses, going forward. Especially since that appears to be the benchmark for large gatherings and international travel without quarantine.
I still can't get my second dose because the AZ vaccine has a 12-week second dose window. They're still setting age benchmarks to allow people to get second doses in Ontario. At this point, it should be a free-for-all.
