The prospects for meeting a clear herd-immunity target are “very complicated,” said Dr. Jefferson Jones, a medical officer on the CDC’s COVID-19 Epidemiology Task Force.
“Thinking that we’ll be able to achieve some kind of threshold where there’ll be no more transmission of infections may not be possible,” Jones acknowledged last week to members of a panel that advises the CDC on vaccines.
Herd immunity was never as simple as many Americans made it out to be, said Kathleen Hall Jamieson, from University of Pennsylvania said. “Humans are not a herd,” Jamieson said.
The chief proponents of herd immunity, the UK and the US, have, by their own admission, recorded nearly 900,000 deaths from Covid in just two years between them. The use of the word genocide in one tweet was entirely justified.
