The green pass for vaccinated against Covid “should be extended to 1 year, it is very likely that the protection will last for that period. The extension, however, should be limited to those who have received the two doses of the vaccine”. This was underlined by Pierpaolo Sileri, Undersecretary of Health, guest of ‘Radio too’ on Rai Radio 1. The certification, according to the hypotheses being studied, could arrive after the first dose with a deadline of more than six months. In this regard, the experts were asked for ad hoc in-depth analyzes. “Generally speaking, the Green pass can be fine in some situations, such as for the reopening of discos and dance halls, but it must not be extended to every activity”, said the Minister of Economic Development Giancarlo Giorgetti. A booster at 6 months (a third dose of the vaccine) is “what we expect from the discussions taking place in Europe, because even with the so-called green card it would currently have a 6-month expiry, which means that my vaccine would have a ‘effectiveness of 6 months. But what do the studies tell us? Today we know that antibodies last at least 8 months, quietly “, highlighted the president of the Italian drug agency Aifa, Giorgio Palù. “It is clear that the titer, that is the quantity of antibodies capable of neutralizing the virus, is gradually decreasing – he specified -. But in many natural infections we are still protected due to cell-mediated immunity. So it could be even more of 6 months, but we will have to connect at European level and establish this ‘deadline’ when we have further data “. Green pass, what is it for? The previous reopening decree introduced the vaccine pass tool in perspective, to make movements more fluid. in and out of regions of different colors. A sort of internal pass. The pass, which can also be issued by the family doctor, can also be obtained by those who have become ill with covid and are cured (it lasts six months from the certificate of healing), those who have carried out molecular tests or rapid test with negative result (lasts 48 hours from the date of the test).
