The tool has two elements: A model of evolutionary sequences that predicts changes that can occur to a virus, and detailed biological and structural information about the virus. Eventually, this information could help scientists develop more effective vaccines and therapies. The tool was able to sift through the tens of thousands of new SARS-CoV-2 variants produced each week and identify the ones most likely to become problematic. The tool was also able to sift through the tens of thousands of new SARS-CoV-2 variants produced each week and identify the ones most likely to become problematic. The ability to do so can help scientists design treatments that are able to withstand the escape mechanisms a virus acquires.
