Field Trials of Vaccines for Marek's Disease

Abstract

Seventeen field trials involving 391,202 birds were carried out in North Georgia to evaluate experimental vaccines for Marek's disease. Herpesvirus vaccines of both turkey and chicken origin were found to be "safe" with respect to their lack of any oncogenic ability in vaccinated birds. However, only the turkey herpesviruses (Georgia strain WHG and East Lansing strain FC126) offered a satisfactory degree of protection against development of the morbidity and mortality usual with Marek's disease.
