“Herd Immunity” as a strategy like Denmark is doing (which means “do nothing”) will produce tragic results. We have umpteen separate epidemics and we are fighting as hard as we can. Eventually we may get to where enough people have had it there are no new customers but let’s say that point is “half the country”. We really don’t want to get there as a strategy. These new interferon type drugs the smart guys are working on, something like the idea of Plaquenil but an actual, working, better drug. Sounds like they are looking at a couple. Space program type effort may get to tool out in months, deploy it, etc. we simply cannot let it get to “herd immunity” because the implication is a major fraction of the population gets it.
Fair enough, and maybe it was a poor analogy. I still think the idea has merit.
