Delta variant, Ricciardi: “Buca also double dose vaccine”

With the Delta variant, today, “even if you are vaccinated you can be infected”. This variant, “even breaks the double vaccination course”, because “it confers a certain protection against serious illness and hospitalization” but “in 30-35% of cases it causes infection even in subjects who have received the second dose of vaccine,” let alone one “. To affirm it Walter Ricciardi, Professor of General and Applied Hygiene at the Catholic University and scientific advisor to the Minister of Health Roberto Speranza, who spoke at ‘Agorà estate’ on Rai Tre.

Ricciardi stressed that the need to vaccinate as soon as possible is also linked to the fact that “the more we hesitate the more we leave the possibility to the virus to select variants that not only puncture the vaccine for infection but also puncture it for protection. Right now we are looking very cautiously at the Delta Plus variant in India and a Lambda variant, which has been isolated in Peru and which worries us a lot. So we vaccinate early, in order to protect people from hospitalization and illness. And then we make decisions as we learn about the variations that emerge in the world. Because in Europe we have vaccinated 50% of the population, but in Africa 1%, in Asia 3%. So the virus now has hundreds of millions of people who can be exercised to try to get around our defenses. “

As for the Green pass ‘all’italiana’, after a single dose “It must be put on file”. The certification “can only be done after the two doses. But by now there is everyone’s agreement on this”. On the subject “I believe we are proceeding. I am not familiar with the decision-making mechanism at the government level, but I know that they are moving in that direction”.
