Message: <blockquote data-quote="Dannyalcatraz" data-source="post: 7972464" data-attributes="member: 19675">Re: problems with Sweden’s reaching herd immunity in weeks:1) if Covid-19’s R0 value is as high as they think it is, they need to reach an exposure rate of @60-70% of their population.2) between the number of asymptomatic carriers and recent revelations as to how long Covid-19 has actually been circulating, there are definitely unknowable variables in determining the actual level of exposure.3) since we don’t even know the strength or duration of post-exposure immunity to Covid-19, “herd immunity” might be essentially worthless, especially considering the number of deaths that would entail.4) with new short-term effects of infection being unveiled almost weekly and (obviously) no data on long-term effects, aiming for herd immunity via exposure versus inoculation may be unnecessarily risky.That said, it‘s true that Sweden may ultimately be mostly right.  If we don‘t develop any treatments or vaccines for Covid-19 in the near future- or ever (coronaviruses are formidable foes for researchers)- humanity won’t have many options beyond accepting occasional disruptions from Covid-19 outbreaks.  But I qualify that with “mostly” because if that is the reality we have to deal with, Sweden’s approach is still probably too laissez faire to be sustainable in the long run.  Adapting to a world where we coexist with Covid-19 will require serious thought about altering the way we all do things.</blockquote>
