Green pass Italy, 9 or 6 months? What Bassetti, Crisanti and Pregliasco say

Green pass from 12 to 9 months in duration. Or maybe even 6 months. The hypothesis of stringent changes to the green certificate, while Italy also has to deal with the increase in infections, is fully approved by the experts. “It is correct to bring the duration of the Green pass to nine months. The data are telling us that at one year the coverage of the double dose does not reach us. But the duration of the green certificate should be differentiated according to the various situations: for the recovered last six months, for those who have had two doses of the vaccine 9 months and those who do the third dose it is reasonable to think that the certificate can be extended to one year, as some studies on the duration of the vaccine recall tell us “, says Matteo Bassetti, head of the infectious disease department of the San Martino hospital in Genoa. “The Green pass must be a dynamic tool.” Everything is always seen as static – explains the infectious disease specialist to Adnkronos Salute – but we are facing a new disease and a new vaccine. Science evolves and we are learning a number of things on the ground. I am happy that there are these changes because it means that medicine changes. A smart thing – he concludes – would be to differentiate the Green pass according to the vaccine doses made and the post-illness, in this case perhaps based on the antibodies that you have “.” A duration of the Green pass of 9 months could be the operative mediation -acceptable technique between 12 months, which are now too many, and 6 months of scientific data, which indicate a reduction in the effectiveness “of the protection conferred by the anti-Covid vaccine, says virologist Fabrizio Pregliasco, professor at the State University of Milan A duration of the certificate “at 6 months could create organizational and management problems”, the expert reasons, recalling that the Green pass obtained by vaccinating “is not a scientific aspect in the strict sense, but it is something that declares the happened. carrying out “the vaccine,” a protective response that nevertheless persists over time “. Because, the virologist recalls,” the protection of the vaccine lasts even after 6 months, it just precipitates and at 6 months and 2 days you are discovered”. Therefore, to facilitate the feasibility “from the point of view, also of the flooding of the recall systems, 9 months – he reiterates – could be the right mediation”. “I am in favor of the choice of reducing the validity of the Green pass”, from 12 to 9 months, as expected in Italy. “It is a step in the right direction, because in some way the duration of the” green certificate “is aligned with the duration of the” anti-Covid vaccination “protection. “In reality, even 6 months is better”, explains Professor Andrea Crisanti, who has long underlined the need to reduce the validity of the pass to 6 months. By doing so, “at this point the Green pass and the protection would be totally aligned”, concludes the director of the Department of Molecular Medicine of the University of Padua. “We need, regardless of the various adjustments in progress, a Green pass capable of providing greater guarantees . The risks are not lacking and the balance of our safety has returned to being precarious, especially if entrusted to a green certificate partially perched on an unlikely buffer which, in a phase of wide circulation of the Sars CoV-2, has enormous margins of imprecision. The third dose is needed, and therefore the vaccine, rather than the Green pass “, says immunologist Mauro Minelli, responsible for Southern Italy of the Foundation for Personalized Medicine.” On the other hand – he observes – having having made the choice of maximum prudence right from the start, the decision to shorten the validity of the Green pass cannot take me by surprise, convinced as I am that it itself is not a lifesaver in itself tto cross the bumpy paths of the epidemic bare-chested. Only a few days ago I took the liberty of hypothesizing, suggesting and even proposing to central decision-makers the opportunity and the usefulness of anticipating that important booster 5 months after the second dose of vaccine in order to confer a more stable and lasting protection “. “In line with scientific evidence, and on the basis of the experience gained following the epidemiological pressure exerted by Sars CoV-2 and its mutations – adds Minelli – I can certainly say that the ‘reduction’ of the Green pass is a natural consequence of that reasoning, aimed at strengthening and concentrating the immune defenses thanks to vaccination, as is right and normal and without substitutes or charitable options. We had already put it on the agenda that the 12 months could be rounded up – he underlines -.
