Delta variant, Crisanti: “Risk of serious illness in vaccinated from 7-8 months”

Milan, 29 July (beraking latest news Health) – “What we see is that the Delta variant” of the coronavirus “can also infect the vaccinated and thus increases the fraction of asymptomatics; in those who have done a single dose it can create serious illness; in those who have done two doses, if they are more than 7-8 months after vaccination and are frail and elderly people, it can cause serious illness “. To underline this at beraking latest news Salute is the virologist Andrea Crisanti, director of the Department of Molecular Medicine at the University of Padua, talking about the ongoing debate on the third dose of the coronavirus vaccine. “For this reason, the opportunity of the third dose of Covid-19 vaccine should be evaluated for the frail. However, we should also see here if there is any data, something that will give us a little comfort”, he adds. A debate heated by some data released by Pfizer in relation to the Delta variant, according to which the third recall would increase the levels of neutralizing antibodies. The third dose is an option towards which Israel seems to be heading, also being examined in other countries, including Italy. “The data must be seen”, reiterates the expert. In general, “anti-Covid” vaccinations will not be enough to stop the infection “with the Delta variant of Sars-CoV-2 running. “In England they do a million tampons a day and have an App system that somehow works, because every day they quarantine almost half a million people. And that’s helping to contain. It’s a strategy that works, I’m saying for a year “. “Vaccinations alone are not enough – he reiterates – so much so that in GB there are 40 thousand cases” per day. “Now they have gone down because, on the one hand, there are no more schools and the Europeans are finished, so the opportunities for aggregation have also been reduced. But what came into play in particular was the tracking system they have” , he insists. The virologist is not surprised by the words of the US scientist Anthony Fauci, who highlighted how the Delta variant has changed the picture and the level of the virus in vaccinated who become infected, a rarer event that can occur, is exactly the same compared to the virus level in unvaccinated people who become infected. “This is normal – comments Crisanti – Didn’t we have the same viral load even in asymptomatic patients? Vaccination is practically increasing the fraction of asymptomatics. What is certainly true is that this variant also infects vaccinated people: in those who have received a single dose. it can create serious illness, in those who have taken two doses, if they have exceeded 7-8 months from vaccination and are frail and elderly people, it can cause serious illness – he repeats – For the rest, the fraction of asymptomatics increases “.
