Definitely. Sweden was the control group for the first wave, unofficial suggestions, no lockdown, though they changed their minds a few months in. We can watch and learn.
With omicron it looks like the lockdown measures don't work as well, and it's propagating anyway. So far measures are just to slow things a bit so the hospitals can cope. Hospital stays are usually shorter, and there are fewer based on the number of cases, especially among vaccinated people.
There are op-ed pages going on about how the US health system is doing better than Canada, but it's not supported by the stats. US hospitals are overloaded as well, they have far more patients and deaths, absolute and per capita, and the hospitals are not able to cope. The US has multiple problems: low vaccination, resistance to masking and distancing, high levels of obesity, and an aging population. They aren't having an easy time, and per capita deaths are triple those in Canada.
There are still more hospitalizations of unvaccinated people even with omicron and it's greater ability to evade the vaccine. Stats show that unvaccinated people make worse health decisions in non-covid areas as well, and I suppose that could be contributing.
