No, herd immunity is still not a viable strategy - and the Barrington declaration is unscientific and unethical - 2020-10-08
The so-called 'Barrington Declaration', calling for a lax approach to COVID-19 and the 'benefits of herd immunity', is nothing more than a fringe viewpoint going against all we've learned in the past months.
The only thing it's succeeded in is making it seem that researchers are divided on the topic when in fact, they're really not, in a fashion that's reminiscent of climate change denial.
A libertarian thinktank and three researchers celebrated with champagne as they signed a document offering an 'alternative' way of dealing with COVID-19. The declaration, which offers little in the way of scientific evidence, claims that a more hands-off approach in dealing with the pandemic: no lockdowns, no closed schools or universities, and a "Focused Protection" where the younger population is allowed to go about their lives normally. Ultimately, the declaration says, we'll reach herd immunity and all will be fine.
Except, almost everything about that is wrong.
