I agree. "Herd immunity" seems like a misnomer. Kind of like "flatten the curve" is a misnomer for attempts at eradication through lockdown. What they're talking about is really just less stringent and less mandated social distancing that hopefully flattens the curve to make the outbreak manageable without eradicating it.
But I think the pragmatic calculus is just this:
Quote:
Lockdowns are simply not sustainable for the amount of time that it will likely take to develop a vaccine.
It should already be obvious, however, that the economic and social costs of lockdowns are enormous: estimates from the OECD suggest that every month of pandemic-related restrictions will shrink the economies of advanced countries by two percent. France, Germany, Italy, Spain, the United Kingdom, and the United States, according to the OECD, will see their economies shrink by more than 25 percent within a year.
Rather than declare a lockdown or a state of emergency, Sweden asked its citizens to practice social distancing on a mostly voluntary basis. Swedish authorities imposed some restrictions designed to flatten the curve: no public gatherings of more than 50 people, no bar service, distance learning in high schools and universities, and so on. But they eschewed harsh controls, fines, and policing. Swedes have changed their behavior, but not as profoundly as the citizens of other Western democracies.
That lockdowns are not
politically sustainable in the US already seems pretty clear. There's also evidence that people started social distancing prior to official stay at home orders (and some, presumably, are continuing afterwards). I think it's clear that
if you have the capacity to execute something like a "5 weeks to eradication" plan and succeed then this is obviously a superior plan. I think that we
could have been much better prepared and should have followed a path like that much earlier. It's certainly hard to criticize the argument that this is/was the right idea.
But since it's also clear it's not happening here for a variety of reasons (some regulatory, some political, some cultural?) I think the other point of the article is probably true, regretfully or not:
Quote:
Whether or not they have openly embraced the Swedish approach, many other countries are now trying to emulate aspects of it. Both Denmark and Finland have reopened schools for young children. Germany is allowing small shops to reopen. Italy will soon reopen parks, and France has a plan to allow some nonessential businesses to reopen, including farmers’ markets and small museums, as well as schools and daycare centers. In the United States, which has by far the highest absolute number of reported COVID-19 deaths, several states are easing restrictions at the urging of President Donald Trump, who despite bashing the Swedish model, is pushing the country toward something very similar.
So, mostly what I'm interested in is trying to guess just how bad the outcome of this will be, and to consider the possibility that more voluntary forms of social distancing will allow us to manage without realizing some of the more apocalyptic projections. TS is clearly correct that more people will die because of it in comparison to the perfect counterfactual response. I don't think it's trivial to weight that against the negative effects of a much longer lockdown in most of the US, but it also seems somewhat academic at this point.
