This is to try to explain the chart in the Lancet study. Only those in red, left of the vertical line are beneficial to lower deaths. Others are ambiguous. |
Summary: for Covid infections the policy responses (above) had some limited effects. For Covid deaths, however, the policy responses had zero unambiguous effects, apart from vaccines, which unambiguously lowered death rates.
I’d argue that deaths per capita are the best comparison, because we know what deaths are and while we can’t know that infection rates were measured in the same way everywhere, no matter how well-intentioned the testing.
For the next pandemic, the lesson is: get making a vaccine. And don’t mandate stuff like school closures, masking, etc.
