Definition:	A synthetic phosphate-linked oligosaccharide analogue that is a chimeric oligosaccharide antigen (ST19AF) comprised of one repeating unit each of the pneumococcal polysaccharides of Streptococcus pneumoniae serotypes 19A and 19F (ST19A and ST19F; CHEBI:62986 and CHEBI:62687). A terminal C5-amino linker enables site-specific conjugation to a carrier protein, to induce protective antibodies against both serotypes.
