MSD Animal Health Launches INNOVAX®-ILT Vaccine in European Union Immunises Poultry against Highly Contagious Respiratory Virus

MSD Animal Health today announced the launch of INNOVAX®-ILT, the company’s novel vaccine that, in a single shot, immunises poultry against infectious laryngotracheitis (ILT) as well as Marek’s disease for use in the European Union. INNOVAX-ILT is MSD Animal Health’s first vector vaccine to launch in the EU, and is the first and only vector vaccine available in the EU to immunise against infectious laryngotracheitis. The vaccine will be available to customers in the UK from November 2015.

“Infectious laryngotracheitis is a significant concern across the poultry industry since the virus – as well as some existing preventative measures – can have a negative impact on growth and overall performance of the chickens,” said Dr. Rik Koopman, Global Technical Director, MSD Animal Health. “What makes INNOVAX -ILT a true advance is that with a single shot; it helps farmers effectively immunise their poultry against ILT virus as well as Marek’s disease, without compromising growth or causing respiratory reactions that impair performance. MSD Animal Health is proud to offer a vaccine that will improve poultry health and efficiency.”

Infectious laryngotracheitis is an acute, highly contagious, herpesvirus infection of chickens and other poultry characterized by severe dyspnea (gasping or shortness of breath), coughing and rales (rattling or abnormal lung sounds). Typically, affected birds also become anorectic (reduced appetite), or inactive. ILT also causes a drop in egg production in laying birds. Infectious laryngotracheitis has been a growing and costly problem in recent years for poultry producers, and the infection can affect broilers as well as breeders and layers.

INNOVAX -ILT utilises the herpesvirus of turkey (HVT) as a vector or carrier virus for infectious laryngotracheitis antigens; HVT has a good safety profile for chickens and also immunises 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 labour 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.

Innovax-ILT is only available upon prescription from your veterinary surgeon. For additional information, contact your veterinary surgeon or a member of the MSD Animal Health poultry team on 01908 685685.
