The World Health Organization has warned for months that herd immunity strategies would not work to control the new coronavirus Fabrice COFFRINI

Proponents of allowing the new coronavirus to circulate among populations in the hope of achieving herd immunity are promoting a "dangerous fallacy" devoid of scientific proof, dozens of health experts said Thursday.
In an open letter published in The Lancet medical journal, more than 80 specialists from universities across the world said that the only effective way of limiting excess deaths during the pandemic was to control the disease's spread.
The letter comes after numerous US media this week reported that senior Trump administration officials had voiced support for an online declaration advocating herd immunity which gathered more than 9,000 signatories worldwide.
As a second Covid-19 wave batters Europe, several countries have reintroduced controls on movement and implemented regionalised lockdowns.
The authors of Thursday's letter said that the social and economic impacts of confinement had led to "widespread demoralisation and diminishing trust" in government measures to get a handle on the virus.
The second wave has also led to a renewed interest in so-called herd immunity, which suggests allowing a large uncontrolled outbreak among people considered to be at low risk of death or serious illness from the virus.
The health experts listed numerous flaws in the concept.
Firstly, "uncontrolled transmission in younger people risks significant morbidity and mortality across the whole population," the letter said.
This would have a catastrophic human and financial cost, besides overwhelming healthcare systems.
The authors also noted that it is possible to become reinfected with Covid-19.
Herd immunity offers no guarantee that those who caught the virus would remain immune to it for any meaningful length of time.
This would present a risk to vulnerable populations for "the indefinite future", the authors said.
- 'Disaster medicine' -
Such a strategy would result in "recurrent epidemics" of Covid-19 similar to those caused by numerous infectious diseases before vaccines were invented.
"It would also place an unacceptable burden on the economy and healthcare workers, many of whom have died from Covid-19 or experienced trauma as a result of having to practise disaster medicine," they wrote.
The World Health Organization has been warning for months that herd immunity for Covid-19 was impossible without untold casualties.
WHO chief Tedros Adhanom Ghebreyesus said the concept was "unethical".
"The vast majority of people in most countries remain susceptible to this virus," he said.
"Letting the virus circulate unchecked therefore means allowing unnecessary infections, suffering and death."
WHO emergencies director Michael Ryan warned back in May that any country pursuing herd immunity were making "a really dangerous calculation".

Herd immunity: Is it a more compassionate approach or will it lead to death or illness for millions?

As coronavirus cases increase across much of the United States, the Trump administration has reportedly adopted a policy of deliberately letting the virus infect much of the U.S. population in order to attain “herd immunity” — despite warnings from the World Health Organization against such an approach. We host a debate on the contentious issue of herd immunity and how best to confront the virus with two Harvard medical experts: epidemiologist Martin Kulldorff, a professor of medicine at Harvard University and one of the lead signatories of the controversial Great Barrington Declaration arguing for an easing of lockdowns, and Dr. Abraar Karan, an internal medicine doctor at the Brigham and Women’s Hospital and at Harvard Medical School who has worked on the COVID-19 public health response in Massachusetts since February.
