CR6261 is a monoclonal antibody that binds to a broad range of the influenza virus including the 1918 Spanish flu (SC1918/H1) and to a virus of the H5N1 class of avian influenza that jumped from chickens to a human in Vietnam in 2004 (Viet04/H5). In contrast to most antibodies generated by exposure to influenza which can only neutralize a few strains from within a single virus subtype CR6261 neutralizes numerous strains from multiple subtypes.
