MSD Animal Health INNOVAX ILT vaccine

MSD Animal Health INNOVAX ILT is vector vaccine available in the EU to protect against infectious laryngotracheitis (ILT). INNOVAX ILT utilizes the herpesvirus of turkey (HVT) as a vector or carrier virus for infectious laryngotracheitis antigens; HVT is well recognized as safe for chickens and also protects against Marek’s disease, another herpesvirus that causes tumors, immunosuppression and sometimes mortality. The vaccine allows birds to develop immunity against infectious laryngotracheitis and Marek’s disease before they are exposed to the viruses that cause these diseases. The vaccine also helps producers reduce labor costs because it requires only a single dose at the hatchery; the vaccine is administered via subcutaneous injection in day-old chicks. The vaccine offers long protection against ILT (at least 60 weeks) in long-lived chickens such as broiler breeders and commercial layers.
