I am not say "always lock down", but when it is appropriate it is a good tool. NSW, Australia was very locked down ... until vaccination rates were up high and then it suddenly wasn't. I feel like although NSW has it's fair share of blunders, it did pretty well overall. Some of that was good luck despite some bad decisions. But I am happy with the lockdowns even though they were disruptive. Some businesses suffered, and some did better. Suburban hospitality seemed to do well as people working from home are now getting their lunch local not in the city.
What natural immunity obtains against variants like Omicron?
And you talk about birth rates being down, what about COVID stillbirths in unvaccinated mothers?
