“The Green Pass objectively and proudly states that people have been vaccinated to protect themselves and others. How to use it is obviously a political choice. But deciding to get vaccinated is an action of solidarity, which allows you to be safer in risky situations such as, for example, sitting at a table in a restaurant or in other closed environments, where positives, even asymptomatic ones, could infect “. of iNews24.it, Fabrizio Pregliasco, director of the Irccs Galeazzi Orthopedic Institute, virologist and professor at the University of Milan, takes stock of the decisions of the control room with Prime Minister Mario Draghi, who met yesterday. Read also ” Vaccination – continues the virologist – from the point of view of the collective interest, is a positive element also because, as is clear, we are witnessing an uphill contagion curve, which however has a small number of serious cases. But it is also a useful element because it reduces healthcare costs, since those who go to intensive care weigh on healthcare. In addition, the return to normal life is now closer. So it is right that there is a political debate on the use of the green pass “. Pregliasco does not exclude the possibility of establishing the vaccination obligation:” The use of the green pass also at national level, seems to me a good decision to ensure that as many citizens as possible get vaccinated – he underlines – especially in this context where no vaxes no longer represent a small number. The convenience, as I said, is there and is proven. I am always of the opinion that the mandatory vaccine would not be an impossible hypothesis: just think that children, in order to go to school, already have ten compulsory vaccinations. The green pass, however, is a way to summarize a choice of freedom, which, even if it is not understood, is more than fair . And from the graduation of its use it will be able to be evaluated gradually. “Finally, on the new parameters of the yellow zone he explains:” This too is a political choice. Clearly, the more we lower the thresholds, the more ‘protective’ we are. Scientifically, there is no exact manual with respect to generalized application. The basic principle is that the increase in the risk of infections increases is directly proportional to the contacts between people. The point is to think about how to lower the infections “.
