New research at Washington University School of Medicine in St. Louis indicates that three new, fast-spreading variants of the virus that cause COVID-19 can evade antibodies that work against the original form of the virus that sparked the pandemic.

Three new, fast-spreading variants of the virus that causes COVID-19 can evade antibodies that work against the original form that sparked the pandemic, new research shows. With few exceptions, whether the antibodies were produced in response to vaccination or natural infection, or were purified antibodies intended for use as drugs, researchers found they needed more antibody to neutralize the new variants. The findings, from laboratory-based experiments, suggest that COVID-19 drugs and vaccines developed thus far may become less effective as the new variants become dominant, as experts say t...
