The organization says that herd immunity is achieved specifically by vaccination. In this regard, most scientists also believe that to prevent the spread of the virus, at least 70 percent of the population living in a particular area should have antibodies to defeat the deadly virus.
However, some experts also believe that if half of the population develops immunity or herd immunity to fight the corona virus, at least a protective effect can occur.
WHO's chief of emergency affairs doctor Michael Ryan rejected a theory on Tuesday at a press conference, saying that we should not sit in the hope of achieving mass immunity.
He said that as a global population, we have not even reached the situation that is necessary to stop the spread of the virus. He said that this is not a solution nor is it a solution that we should look at. Most studies to date have shown that only 10 to 20 percent of the population has related antibodies.
Senior Advisor to the Director General of WHO, Dr. Bruce Alward, also said that the aim of comprehensive vaccination with a Kovid-19 vaccine would be to bring more than 50 percent of the world's population under its purview.
