“The blockade has made Covid more evolved“Guido Rasi is sure of it, microbiologist from the University of Rome Tor Vergata, until mid-November director of the European Medicines Agency Ema who yesterday gave the green light to vaccine anti-Covid di Pfizer / BioNTech. “ll lockdown, in a sensible match, – he explains – made him realize that he had to become more efficient“.
What are the factors that contributed to the mutation Sars-Cov-2 virus is not yet clear. It is true, at least from the first observations, that the now known “English variant” (VUI-202012/01, this is the name) highlights the modification of one of the 1250 amino acids contained in the peak protein, that is , that portion that the pathogen exploits to adhere to human cells and infect them. According to British Health Minister Matt Hancock, the ‘new virus’ could spread more easily. Not only that, already 60% of the new positives reported in London would be attributable to this variant: around 28% of all cases registered in England in the last month. But what is the underlying cause of this sudden and unexpected evolution?
An interesting test is that offered by Professor Guido Rasi, a microbiologist at Torvegata University, according to which the mutation is the result of a “boomerang effect” of emergency shutdown. “Like any virus – clarifies in an interview with Sole 24 ore – this also has a diabolical character and its mutation until now has been to learn to enter cells even better and to replicate by optimizing their structure. The blockade made him realize that he needed to be more efficient.“.
Given the evidence collected, the fear expressed by experts is that the new mutation could affect the effectiveness of the vaccine. It’s about a fear founded? “For now, this is an unlikely hypothesis.”Continues the expert who, until last November, was responsible for the European drug agency Ema, which yesterday gave the green light to the Pfizer / BioNTech anti-Covid vaccine, the same one that yesterday gave the green light Pfizer / Anti-Covid vaccine BioNTech The fact is, after all, the “English variant” is highly contagious. “This tells us something very clear, and it is that now it is essential to carry out a rapid and massive vaccination campaign because we have seen that the virus, when under pressure, brings out its evolutionary capacity. – explains Rasi – And now that the vaccine will arrive, it will try to find new ways to survive, but what mutations we unfortunately do not know before. However, we know that the dangerous ones are simultaneous multiple mutations.“. And the Gb variant was one of these.”then we should worry – conclude –because it could make vaccines less effective or ineffective. Such a substantial mutation would change the personality of the virus and also the way it enters cells. It would almost turn into another virus“.
