Covid, Silvestri: “Possible less benign virus evolution, crucial boosters”

“Looking ahead, there are some things we should focus on” in the fight against Covid-19 according to virologist Guido Silvestri, a lecturer in the US at Emory University in Atlanta. “The first is that the protection conferred by vaccines, although powerful, has a limited duration in time, and therefore it is important that we insist on booster doses and with the timing indicated by the experts (Cdc, etc.), rather than insinuate doubts about them. safety and efficacy, “he explains in a post on Facebook. Moreover, he adds, “on Omicron it should be understood that the virus could – a rare possibility, but not impossible – evolve in less benign directions. In this case, again, the way would be to insist on vaccines (even with research and development of ‘pan-Covid’ products) and to enhance health services “.
