Herd immunity? “In Italy at the end of August, the first half of September, by vaccinating at least 65% of the population, we will be able to achieve ‘solidarity or social immunity’, that is, we will have secured even people who cannot be vaccinated, and we will be able to afford reopening and socialization “. This was said to Adnkronos Salute by the immunologist of the Policlinico Umberto I in Rome, Francesco Le Foche, who underlined how the concept of herd immunity should be ‘reviewed’ in new terms. In fact, the expert expands the concept “which today – he says – must be conceived in different terms from the past, as in the globalized world, where we are moving very quickly, as demonstrated by the virus, which has quickly transformed a Chinese epidemic into a pandemic, herd immunity must provide for a planetary immunity. That is: we must vaccinate others to protect everyone. It is a bit like the immune system – he says – which protects the species and not the individual but protecting the species protects the individual. The same must happen globally: we protect others, we protect everyone to protect ourselves too “, he concludes.
