The protection of the herd is expensive

Earlier this month, three prestigious academics (Oxford, Harvard, Stanford) drafted a proclamation inviting colleagues from around the world to sign it. The proclamation, called the Great Barrington Declaration (from the city of Massachusetts where it was signed), calls on governments to change their pandemic policies dramatically. Calls for the virus to be allowed to spread freely among young and healthy people (while at the same time vulnerable people will be protected), in order to infect a sufficient percentage of the population and obtain the infamous immunity of the herd. This term, with which many scientists disagree preferring the term “herd protection”, describes the inability of a pathogenic microorganism to spread to a population because it constantly encounters individuals who are immune to it. Under normal conditions, immunity is achieved through vaccination and the percentage of the population that must be vaccinated to protect the herd from vulnerable and non-vaccinable individuals depends on many parameters, mainly the transmissibility of the microorganism. Ten days after above declaration came a “paid response”. More than 30 top scientists co-authored the John Snow Memorandum (named after one of the “fathers” of epidemiology) and in a letter to the medical review “The Lancet” called it a “dangerous fallacy unsupported by scientific evidence” that by allowing the low-risk population to become immune through infection, the population vulnerable to SARS-CoV-2 will be gradually protected. By the time these lines were written, only 42 scientists had signed the declaration of three, while more than 5.5 Thousands of scientists had signed the John Snow Memorandum. And while it is scientifically clear where the scales are tilted, life itself gives its own answers: in Sweden, where a model of herd protection was implemented, the number of deaths per 100,000 population was ten times higher than in neighboring Norway. . It is estimated that in order to protect the herd in the US, about 2 million people will need to die! In other words, the increased cases of young people observed recently in our country can not work as a vaccine for older people. in Google News and be the first to know all the news See all the latest News from Greece and the World, at
