Bispecific antibody shows improved efficacy against SARS-CoV-2 variants

Researchers from The University of Texas MD Anderson Cancer Center have developed fully human bispecific antibodies, as revealed in a recent study. These antibodies can bind to two distinct epitopes of the receptor binding domain (RBD) of the SARS-CoV-2 spike protein and have demonstrated the ability to neutralize various strains of the virus, including the Omicron variant.
