Although for months there has been talk of herd immunity, of objectives to be achieved regarding vaccinations against Covid, to date, according to experts Andrea Crisanti and Fabrizio Pregliasco, we are still on the high seas. First of all, to have herd immunity you should have “85 percent of the protected population but the vaccine only lasts six months and most of the vaccinations date back to April-July, those people should be revaccinated”, says Crisanti al Fatto Daily. Pregliasco shares the same idea: according to him mass immunity is reached “with perhaps 90 percent of vaccinated people including children under the age of 12. But a certain fear has spread about vaccinating younger children”, thunders.
The opinion of Andrea Crisanti
Crisanti speaks of a “political problem”. The director of Microbiology of the University of Padua explains that “most of the vaccinations date back to April-July, those people should be revaccinated: we would have to do eight million vaccinations a month for six months to have 48 million people protected”. After six months, in fact, the protection against serious illness “drops to 65-70 percent” while the protection from infection “to 40 percent”. And he adds to the dose: “The problem is that they played hypocritically with the Green pass and wrapped up”. So the third dose “if we are to protect our health system we must do it to the elderly, guests of the Rsa, cancer patients and other frail people, as is already being done, but it is not enough. As long as we have 10 million unvaccinated, the virus will be transmitted , will continue to circulate “, says Crisanti for whom” we are trying to buy time waiting for a more effective vaccine and more effective drugs, as with the lockdown. Today we have a vaccine that works only a little. The battle is this , we are still in the trenches “, he concludes.
And that of Fabrizio Pregliasco
Pregliasco, on the other hand, highlights how the green pass is “disconnected from vaccinations, it is a political-technical element that serves to induce vaccination” also because “after six months the vaccine begins to lose its effectiveness, but keeps it at a good level for forms more serious, which is what we were looking for. We will see if it will be necessary to revaccinate everyone. Even with a low antibody titer, there is protection “, says the doctor, who then warns:” Winter could be the last battle, we will win it unless a weird, nastier viral variant emerges, but it’s not that likely. “
