On herd immunity: By now we should have all read that recent studies show that detectable antibodies in recovered patients diminish rapidly in just a few months, Immune responses are more complex than that however, and there don’t seem to be any peer-reviewed studies on T-cell response over time. The herd immunity theory of slowing Covid-19’s spread sounds good in theory, but as yet there are no facts in evidence that it is effective or long-lasting.
The Swedish laissez-faire model has resulted in a higher per-capita death rate with exactly the same economic damage compared to its Scandinavian peers. There is obviously lots of short term pain on that road with an uncertain and unquantifiable reward.
