World Health Organization chief calls herd immunity approach `unethical`

World Health Organization chief calls herd immunity approach `unethical`”

Seroprevalence research suggests that in most countries, less than 10% of the population was infected, detailed Tedros Adhanom Ghebreyesus.

"There has been some discussion recently about the concept of reaching so-called "herd immunity" by letting the virus spread, Tedros said, adding that herd immunity is a concept used for vaccination, in which a population can be protected from a certain virus if a threshold of vaccination is reached".

Less than 10% of the global population has been exposed to the virus, the World Health Organization estimates, meaning that the vast majority of people remain susceptible.

"Allowing a risky virus that we don't fully understand to run free is simply unethical".

Relying on naturally obtaining herd immunity would be "scientifically and ethically problematic", he added.

He stressed that the concept of herd immunity is used in vaccination campaigns and recalled that for smallpox it is required that 95% of the population be vaccinated so that the remaining 5% is protected.

His comments, made at a press briefing on Monday, came days before senior United States officials said the White House was warming to the herd immunity strategy.

COVID-19 patients may experience more severe symptoms the second time they are infected, according to research released Tuesday confirming it is possible to catch the potentially deadly disease more than once. Allowing a risky virus that we do not fully understand to run freely is simply unethical. "We must save lives with the tools we have at hand", said the WHO Chief.

Tedros made the comments as cases continue to skyrocket in Europe and the Americas, with the world setting record daily highs for infections on each of the last four days.

The coronavirus has killed over one million people worldwide and infected more than 37.5 million.

Tedros has urged governments to pursue comprehensive plans that include widespread testing, social distancing, and other preventive measures, such as face-mask wearing, alongside a global push to develop a vaccine.

In fact, the World Health Organization is working with the European Centre for Disease Prevention and Control to help countries evaluate the effectiveness of their digital contact-tracing apps, he added.

The WHO encourages using systems to track, test, and isolate cases of the virus before they spread.
