Vaccine targets to protect against multiple Salmonella types

Target Antigen Identification to Generate a Cross-serovar Salmonella Vaccine

['FUNDING_R01'] · UNIVERSITY OF CALIFORNIA AT DAVIS · NIH-11324315

This project aims to find parts of Salmonella bacteria that could be used to make a vaccine protecting people from different types that cause serious bloodstream infections.

What this research studies

Researchers are building a new mouse model to compare how typhoid, paratyphoid, and non-typhoidal Salmonella cause disease and respond to vaccine strategies. They will look for bacterial pieces (antigens) that trigger liver-resident CD4 T cells to protect against multiple serovars. The team will test which antigens produce the strongest, lasting immune responses in the model. These lab and animal studies are an early step toward vaccines that could prevent severe systemic Salmonella infections in people.

Who could benefit from this research

Good fit: People at risk of systemic Salmonella infections—such as those exposed to typhoid, paratyphoid, or non-typhoidal serovars—would be the eventual candidates for vaccines developed from this research.

Not a fit: Because this is preclinical, it will not directly treat people with an active Salmonella infection now and may not immediately help those who are critically ill or severely immunocompromised.

Why it matters

Potential benefit: If successful, this work could lead to a vaccine that protects people against several major types of systemic Salmonella infections and reduce related illness and deaths.

How similar studies have performed: Typhoid conjugate vaccines exist, but developing a single vaccine that protects across typhoidal, paratyphoid, and non-typhoidal serovars is novel and largely untested in humans.
