We're also 'lucky' that so many advanced regional health authorities are trying different experiments, because it will allow us to tease out data for the future.
We're also having a hard time measuring what we consider 'success' or 'failure', mainly because we disagree on what's the actual goal. Zero in the ICU? A steady ICU caseload? Zero transmission amongst the vaccinated? Nevermind how much we're willing to pay for each percentage success on each of those indicators.
Success is well-defined regardless of the game's outcome, when it is tied strictly to mere participation.
Also, has there been any study about effects from the measures to very young kids? A considerable number of 5-6 year olds have lived 1/3 of their life in rather unusual circumstances, and it is unlikely this won't lead to stuff down the line.
