Cross-reactive immune response elicited by parenteral Vi polysaccharide typhoid vaccine against non-typhoid Salmonellae.

Highlights: [•] There are no vaccines available against non-typhoid Salmonellae (NTS). [•] Typhoid vaccine Ty21a elicits antibodies to NTS strains with typhoidal O-antigens. [•] Vi vaccine elicits a response to typhoidal O-antigens. [•] Vi vaccine elicits cross-reactive response to NTS strains with typhoidal O-antigens. [•] The response with Vi is lower than with Ty21a.
