Tedros Adhanom, The Director General of World Health Organization cautioned against the possibility that herd immunity might be a practical strategy to stop the pandemic, referring to such recommendations as “simply unethical.”
While addressing to the media, the Director General told that that heard immunity is aimed to be achieved by vaccination by the health officials. He said that for example; about 95% of the populace had to be vaccinated, in order to obtain herd immunity from a highly infectious disease such as measles.
He said, “Herd immunity is achieved by protecting people from a virus, not by exposing them to it. Some researchers have argued that allowing COVID-19 to spread in populations that are not obviously vulnerable will help build up herd immunity and is a more realistic way to stop the pandemic, instead of the restrictive lockdowns that have proved economically devastating.
“Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak,” he added.
According to the Director General there is not much information known regarding the COVID-19 immunity to even believe that herd immunity is achievable.
“We have some clues, but we don’t have the complete picture,” he said, keeping in mind that WHO had recorded occurrences of individuals turning out to be reinfected with Covid after recovering from an episode of the virus. He further said that while the vast majority have seemed to build up some sort of immune response to the virus, we still are not aware of how robust that protection is or how long it lasts — and that every person has a different reaction to it.
He further said, “Allowing a dangerous virus that we don’t fully understand to run free is simply unethical.”
According to The World Health Organization under 10% of the populace has any resistance to the virus, which means, by far, most of the world stays susceptible.
Tedros additionally said, that for the last four days, nations had detailed record-high day by day figures of virus to the U.N. wellbeing organization throughout the previous four days, referring to increase in cases in America and Europe specifically.
