As Covid-19 surged last year, governments worldwide touted the hope of “herd immunity”, a promised land where the virus stopped spreading exponentially because enough people were protected against it. That is now looking like a fantasy.
This month, the Infectious Diseases Society of America estimated that Delta had pushed the threshold for herd immunity to well more than 80% and possibly close to 90%. Public health officials such as Anthony Fauci have drawn controversy by shifting the goalposts over the past year, increasing the number of people who need protection before hitting herd immunity. Meanwhile, vaccine hesitancy and supply issues mean most countries will not get close to even the original numbers.
“If it was as simple as getting the infection once means you are immune for life, that would be great, but I don’t think that’s the case,” said SV Mahadevan, director of South Asia Outreach at the Center for Asian Health Research and Education at Stanford University Medical Center. “That’s a troubling problem.”
Because you are forcing people.
