Researchers in California have made a breakthrough in the development of a vaccine to protect against a common food-bourne illness.  Avoiding stomach pains in the U.S., though, isn't the goal.

FOX News Radio's Chris Hoenig reports:

A Salmonella vaccine may be closer than ever.

(McSorley) "I would hope that we would have a vaccine available within the next 3-5 years."

Dr. Stephen McSorley at the University of California-Davis leads the research team that has taken huge steps in controlling the bacteria.

(McSorley) "What we've done is we've identified the components you would need to have in a vaccine."

...A vaccine that would treat deadly types of Salmonella, such as Typhoid, which kills 200,000 people a year.  The goal is first to treat the strains of the bacteria that kill one of every four people it infects in Africa, but could find use here in the U.S.

(McSorley) "A vaccine like that could be used for, maybe, particular at-risk individuals that would be at risk of serious infections with Salmonella poisoning through food."

...Such as those with underlying health conditions.
