Study: Few ‘important’ genetic changes seen in COVID-19 since hop to humans
March 12 (UPI) -- The genetic makeup of the coronavirus underwent few "important" changes during the first 11 months of the pandemic, despite the emergence of potentially dangerous new strains last fall, according to a study published Friday by PLOS Biology. After analyzing hundreds of thousands of sequenced virus genomes, researchers from the United States, Britain and Belgium documented little significant alteration in the virus' genetic structure since it jumped to humans. Advertisement This was the case until late in 2020 -- after nearly a year of the virus circulating widely among people in nearly every nation on Earth -- when new variants began to emerge as a result of limited immunity in people who'd already had the virus. The vaccines developed to fight off the virus should contin...
