Vaccination of bursectomised chickens with inactivated Marek's disease virus-specific antigens.
Bursectomised chickens were protected against Marek's disease (MD) by vaccination with inactivated MD virus-specific antigens. The immunity was associated with lowered lymphocyte-associated MD viraemia following challenge. Evidence is presented that the immunity was not dependent on a humoral immune response but possibly on the presence of lymphocytes sensitised to virus-specific antigens.
