“In this fantastic month there have been 7000 deaths, we are on the way to overtake England and become the first country in Europe for mortality. I make a paradoxical reasoning. Even if nothing had happened, would it have been right to release the brake on the Mottarone cable car? We took an unnecessary risk “with the reopening decided on April 26. Professor Andrea Crisanti, a guest of Piazzapulita, does not change his mind after having judged the decision to proceed with the reopening incorrect at the end of April.” England had indicated the way to follow: today it has 2-5 deaths, we have 70. We are talking about a month of great success, in this period we have had 7000 deaths. At the end of this epidemic I want to be remembered as a prudent person, not optimistic or pessimistic “, says Crisanti. For the future” the duration of the vaccine protection will have an impact on the whole system: it is one thing if it lasts 9 months, another count is if it lasts 18. We then need vaccines that can be administered with a single dose “. In recent weeks the theory relating to an artificial origin of the coronavirus has resumed.” It is true that the genetic editing processes have made exceptional progress, however, if we change a piece of the DNA of a virus, it is as if we were putting a new page in a 16th century book. This misalignment would be seen and at this moment the presence of a new page in an old book has not been proven “, says Crisanti. Could the virus have escaped from a laboratory?” Possible, but difficult to prove “, says the professor, placing l emphasis on a general question, linked to the dependence of scientific laboratories on the ministries of defense in different countries.
