“The white areas? I see them badly. The problem is that we must not miss the opportunity to get involved with the tracking, instead the risk is that fewer swabs are done because the more swabs are done, the more cases emerge and the more the regions risk falling back into the color range “. Virologist Fabrizio Pregliasco of the State University of Milan tells Adnkronos Salute. “It should have been a rewarding mechanism: the more you do, the better – says Pregliasco – instead it is quite the opposite. We should insert – he proposes – a standard quota based on the population involved”. As for the “openings we are making with even excessive enthusiasm” Pregliasco points the finger at incorrect behavior: “Young people are terrible, I’ve seen them around. I didn’t tell them anything – he concludes – because I was in the car”. Vaccine chapter: “I do not mind the idea of a vaccination obligation. It is a defeat in some ways, but it can be decisive especially for the groups most at risk, which are the elderly”. “The approach – recalls Pregliasco – was right from the start it was not compulsory, so it would be a going back that would be more understood if there were to be a fourth wave, but in a phase like this in which there is a free all would not be understood. – concludes the virologist – now it is vaccinating whoever wants it. “We speak of booster or third dose. “It would be better to be able to update the vaccine before the third dose but to maximize, also considering the effort behind it, for now I would say let’s get into it with the first round and let’s organize ourselves so that there can be the third dose in 2022”, he observes . “We still do not have precise information – explains Pregliasco – to say when the recall will be done. We do not know how long the immunity lasts. A good test was at six months and we saw that the antibody presence is still good, it is likely that yes certifies much more and maybe even a residual protection remains, so we really don’t know yet “.” It is predictable – says the virologist – that it will serve as for all coronaviruses. And maybe at the end of this first round, when we would not have yet reached herd immunity, perhaps for the elderly and the most exposed subjects a recall will be necessary on the basis of an influenza-like strategy. gga from influenza and Covid-19 “.
