Elanco Animal Health has launched AviPro Salmonella Duo, a new live vaccine which provides simultaneous protection against S Enteritidis and S Typhimurium in poultry.

Jessica Cross, Elanco's poultry veterinary consultant said: "AviPro Salmonella Duo is the first vaccine to have both Salmonella strains in the same vial and also the first to be licensed for turkeys and ducks as well as chickens."

Unlike inactivated vaccines which are administered by injection, AviPro Salmonella Duo is administered in the drinking water. Elanco says this offers producers significant advantages since the oral route allows mass administration without stressing the birds, saving labour and improving welfare. A three-dose programme provides immunity throughout lay.

The new vaccine also provides an eight-week increase in the period of immunity over its predecessor, to 62 and 68 weeks of age for S Typhimurium and S Enteritidis respectively.

Jessica said: "This development represents the third generation of vaccines, moving on from the early dead vaccines, individual live vaccines to the bivalent product. Producers will welcome the simplified administration it offers."
