Severity of current SARS-CoV-2 variants is not linked to the number of mutations

New research from UNC Charlotte’s Center for Computational Intelligence to Predict Health and Environmental Risks (CIPHER) has found that the two most prevalent strains of the virus that cause COVID-19, SARS-CoV-2 variants BA.2.86 and JN.1, are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a high number of mutations compared to previous variants.
