“The Delta variant is totally dominant in the US. The picture has completely changed: the level of virus in vaccinated people who become infected is exactly the same as the level of virus in unvaccinated people” who are infected. These are the words of Professor Anthony Fauci, consultant immunologist to American President Joe Biden, who in the last few hours has spoken on several occasions after the new guidelines of the Centers for disease control, which recommended the use of masks indoors also for vaccinated in USA. In a first interview with MSNBC, in particular the ‘All in with Chris Hayes’ program, Fauci referred to “clear data”. “Two months ago, the level of virus in the mucous membranes of a vaccinated subject was significantly lower: now the Delta variant has completely changed the scenario”, the scientist’s words.
In a subsequent interview with the ‘Morning Joe’ program, Fauci broadened the picture. “Two months ago the CDC said that vaccinated people shouldn’t wear masks indoors. Now, one thing has changed: the virus has changed. The CDC hasn’t made any reversals. When the previous recommendation was made, we had a dealing mainly with the Alpha variant. A vaccinated person, if positive, would hardly have transmitted the virus. Now we are dealing with the Delta variant, which is much more contagious. The most recent data clearly shows that when a person vaccinated it becomes infected, it can transmit the virus. For this, the guidelines have been changed, “says Fauci.
“A vaccinated person, even a positive one, is unlikely to go to hospital or die. But if a vaccinated person becomes infected, he can transmit the virus to frail people or unvaccinated children: we don’t want that to happen. When children get infected, someone of them get sick and die: we have had 400 deaths among children from covid. We must not think that the infection among children is not worrying: we must protect them, even if a serious evolution of the disease is less likely. The vaccine is the more immediate solution to the problem: there are 100 million people in this country who have not yet been vaccinated. We have to get to them and get them vaccinated, “he says. “The Delta variant is here, if we get to 85-90% of the population vaccinated, the Delta variant wouldn’t have many places to go. Now, thankfully, we have enough vaccinated people and we won’t have a wave between them. People he does not realize one thing: as long as there is high circulation of the virus, we give the virus the chance to vary even more and we risk a variant worse than the Delta, a variant that not even the vaccinated could handle “.
