Blocking influenza virus infection using an α2,6-sialoglycopolypeptide. The α2,6-sialoglycopolypeptide was enzymatically synthesized from an (γ-PGA)-based glycopolypeptides carrying α2,6-sialylated glycans acted as inhibitors of influenza virus because human viral HAs bind to α2,6-linked sialosides in the core glycan structures
