PROBLEM TO BE SOLVED: To synthesize a mutant Neiseria oligosaccharide structure, a vaccine preparation containing a mutant Neisseria oligosaccharide structure prepared from the Neisseria strain, a method for producing the mutant Neisseria oligosaccharide structure, and a method for producing the vaccine preparation To provide. A Neisseria that lacks the reading frame and does not express the glycosyltransferase from a Neisseria strain having a reading frame encoding a glycosyltransferase selected from the group consisting of LgtA, LgtB, LgtC, LgtD, and LgtE. Strains, vaccine preparations containing the mutant Neisseria oligosaccharide structures prepared from the Neisseria strains, methods for producing the mutant Neisseria oligosaccharide structures, and methods for producing the vaccine preparations.
