The so-called "Herd Immunity" is a mechanism according to which, when the majority of a population is immune to an infection (because it has been infected or vaccinated), the pathogen does not find people to be infected, making it indirectly protected, even those few people who are still vulnerable. Herd immunity cannot be induced voluntarily by allowing the greatest number of people to become infected, rather it is an objective achieved through vaccination campaigns. These campaigns, starting from an immune population base, consolidated after the first wave of an epidemic, after the production of the vaccine are carried out for all people by health personnel, starting from the most at risk or the weakest.
It's being talked Cambodia Telegram Number Data about a lot now, because in Great Britain, a government scientific adviser, Sir Patrick Vallance, explained that for now the strategy for containing the virus is to develop a certain population immunity. And for them having done this, according to him, 60% of the population should be affected by Covid-19. The country should prepare to "lose loved ones prematurely", said Prime Minister Boris Johnson). How successfully has the mechanism been used? "The most important success has been the one against smallpox - answers Paolo Bonanni, professor of Hygiene at the Department of Health Sciences of the University of Florence. We have done it, reaching about 85% of vaccination coverage in the whole world, including the most remote areas of the globe.
It is not easy to achieve herd immunity, even when there is a vaccine, and it is even more difficult to achieve the total eradication of a disease. Vaccination coverage must be high everywhere in the world, and if the viruses we face (such as the coronavirus) come from the animal world, complete elimination is nearly impossible. Smallpox was a human-only virus. Even poliomyelitis is like that, in fact it has almost completely disappeared." Is it risky to aim for "spontaneous" herd immunity? "It would mean allowing the virus to circulate without control measures, and there would be an intolerable death toll, not to mention the situation in hospitals.
