An oligosaccharide useful for a Meningitidis A vaccine contains a first mannose unit having a spacer in the alpha configuration at C-1, which spacer is capable of conjugating to a protein, and which is connected to a second mannose unit through a 1,6-linkage which connects C-6 of the first unit to C-1 of the second unit, wherein the 1,6-linkage comprises a phosphonate. Related methods of making such compounds, analogous compounds, or intermediates thereof are also disclosed.
