Chickens vaccinated with HVT developed lymphoproliferative lesions and a cell-mediated immune response to MATSA. These observations are considered in view of the overall mechanism of vaccine protection in MD. A mechanism of vaccine action is proposed that suggests that MATSA immunity in vaccinated chickens may play an important role in protection.
