Merial’s poultry vector vaccine VAXXITEK HVT + IBD, which protects chickens against infectious bursal disease and Marek's disease, has been launched in China.  

Chinese poultry producers began field trials with the vaccine in May 2010. “Producers only need a single injection, which can be delivered automatically in ovo or in SQ day-old birds," said Dr. Stéphane Lemière, Merial's head of global avian technical services. "Protection continues throughout life and, unlike classic vaccines, VAXXITEK HVT + IBD has little or no immunity gap between the end of maternal antibody protection and the onset of immunity.”

The vaccine, which is currently registered in 66 countries, was first introduced in Brazil in 2006.
