Covid vaccine, Silvestri: “Dangerous to talk about herd immunity now”

It would be “dangerous” at the moment “to think that vaccines already work in giving herd immunity” against Covid-19, “when the percentages of vaccinated people are still relatively low, like the current ones”. This is “really the tipping point” according to virologist Guido Silvestri, a lecturer at Emory University in Atlanta. “This attitude – he warns on Facebook, in a post on what he calls” deniers “of the seasonality of the pandemic coronavirus – would lead to relaxing the vaccination campaign, when instead we must push everyone to vaccinate like crazy, from now until October, in Italy as in Europe and North America, taking full advantage of the summer truce – urges the Italian scientist in force in the US – to reach that quota, which many place around 70-80%, which will really allow to stop the spread of Sars-CoV- 2”.
