On Monday, the White House hosted a pandemic-focused call for the press “on background”—intended to provide a window into the administration’s thinking, but not to provide quotes that could be attributed to any government official. During the call, the unspecified White House officials touted a document supporting the idea of herd immunity as a plan to control the pandemic, saying it reflected the administration’s thinking.

The document, called the Great Barrington Declaration, was prepared by a libertarian think tank with the assistance of a handful of scientists who have been pushing the idea that COVID-19 isn’t much of a threat. And it has attracted enough attention that the World Health Organization decided to address it. The result severely undercut whatever the White House intended to accomplish.

“Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic,” the WHO’s Tedros Adhanom Ghebreyesus said. “It’s scientifically and ethically problematic.”
