A bispecific antibody targeting conserved hemagglutinin epitopes confers broad protection against H7 avian influenza and accelerates viral clearance via localized respiratory delivery
ABSTRACT The continuous antigenic drift of zoonotic H7 avian influenza viruses remains a significant global public health threat. While monoclonal antibodies (mAbs) targeting the hemagglutinin (HA) head offer potent neutralization, their efficacy is often undermined by rapid viral escape. In this study, we systematical...
