Yes, more stringent lockdowns AND our current rate of widespread vaccinations would’ve prevented more deaths. I guess if you think the level of deaths was OK, then it was a success. I think we could’ve done more.
In Ontario, I think the vaccination approach didn't evolve with variants. We saw that young people were getting sick and dying. Vaccines should have targeted hot spots once available. Not vaccinating older people first.
I don't think lockdowns should have prevented the third wave, only vaccination has done that.
Regardless, Lockdowns should be used to prevent Hospital System Collapse, not to ensure COVID-19 Zero.
