Covid and the origin of the pandemic. For Massimo Clementi, director of the Laboratory of microbiology and virology of the San Raffaele hospital in Milan, the virus did not come to humans from animals. “Something happened that shouldn’t have happened and it didn’t happen because a virus, like Sars in 2003, passed through the Chinese food market and infected humans through various animals,” he told the microphones of ‘The entrepreneur and the others’ on Cusano Italia Tv. “The Sars-CoV-2 – explains Clementi – has an enormous diffusivity, but a relatively low mortality and this has generated doubts and perplexities”.
“If you are immunized with both doses of” Covid vaccine, “you have a low chance of getting infected; if you only took one dose, you have too low an antibody level“Clementi says speaking of the new cases of contagion in the United Kingdom, linked to the Indian variant of Sars-CoV-2.
“I was favorably surprised – he says – by the fact that in Great Britain, despite starting late, with an epidemic that at Christmas had reached very high levels in that country, using the single dose strategy AstraZeneca everyone managed to have a global protection that has stopped the epidemic. So – he repeats – chapeau to Johnson and to this strategy that also went against some dictates of a scientific nature. for example the Indian variant which is particularly ready to infect even people with antibodies, especially those who do not have high immunity “.
If the third dose of the anti-Covid vaccine “will be necessary, we will have to decide in September-October, because at that moment we will have an overall assessment of the current situation: how many subjects will be vaccinated, how many will have achieved full immunity and also what the pharmaceutical industry will tell us “.
“These vaccines – he underlines – can be modified in a tailor-made way with respect to the virus that circulates, this is the great advantage that the messenger RNA technology has given us. This will radically change our way of approaching infectious diseases”.
Experts on TV
“With this pandemic they have arrived on television by ‘virologists-non-virologists’ who have taken over the scene, but they are people more used to cabaret than to science“.” These people – he says – have represented, especially in the media, a destructive element towards the scientific discipline. We – he warns – must prepare real virologists for tomorrow, people who work at the interface between the animal, human and natural world, because epidemics of this type are born there “.
