“Herd immunity understood as immunity of the category that goes from 16 years upwards is presumed to be obtained, that is, a coverage objective beyond the threshold level imagined based on mathematical models” to have a significant shield against Covid. “In fact, however, the virus will still remain.” Fabrizio Pregliasco, a virologist at the University of Milan, explains it to Adnkronos Salute. “It will also be necessary to vaccinate the youngest – he observes – Fortunately, things seem to be possible. At least from the age of 12 onwards”, given that the extension of the use of the Pfizer vaccine for the 12-15 age group, “and we will now see the studies also for the smallest children. So I repeat: herd immunity is a goal to strive for and it is right to talk about it, knowing that ‘elimination of “Sars-CoV-2” in real practice with this type of disease and vaccine, but rather to containment and an increasingly civilized coexistence with the virus “.
Cohabitation that “will presumably require reinforcements and vaccine boosters in the near future”, concludes Pregliasco.
