The head of the World Health Organization warned on Monday that suggestions by some would be approved. COVID-19 Spread in the hope of achieving the so-called Bunch immunitySaying, this is “immoral.”
“The immune system of the herd is acquired by protecting people from the virus, not by exposure to it,” Tedros han dhanom he brabius said during a virtual press briefing. He explained that “flock immunity is the concept used for vaccination, in which the population can be protected from certain viruses if the threshold of vaccination is reached.”
He pointed out that for measles, for example, it is estimated that if 95% The population is vaccinated, The remaining 5% will also be protected from the spread of the virus. For polio, the threshold estimate is 80%. Animal husbandry helps protect those with weakened immune systems, such as infants and those with compromised immune systems who cannot be vaccinated.
However, Tedros said, “Never in the history of public health has an epidemic-related immune system been used to respond to an epidemic outbreak, let alone an epidemic.”
According to Johns Hopkins University, between 0 and 90% of Americans need coronavirus antibodies to gain immunity. But there is a nation Nowhere near that level Yet, more than 8 million people have tested positive and 214,000 have died since the epidemic began.
Also Once the vaccine is approved, It is unclear how many people will receive it immediately. Opponents of the vaccine have begun efforts to unveil the future vaccine in early April, months before any clinical trial.
A midterm poll conducted by the Associated Press and the University of Chicago found that nearly half of Americans said they would get the COVID-19 vaccine, and about a third were unsure. About 1 in 5 people said they would refuse.

Covid-1 has killed more than a million people and infected more than 37 million since it first came out in China late last year.
“It’s a scientific and ethical problem to rely on natural animal husbandry to get immunity in such a situation,” Tedros said. “It’s unethical to allow a dangerous virus that we don’t understand to run for free.” That’s not an option. “
He noted that doctors still have a long way to go to learn about the development of COVID-19 immunity, including how strong the immune system is and how long antibodies are in the body.
He also noted that in most countries, less than 10% of the population is thought to be infected.
“Most people in most countries are susceptible to this virus,” he said.
