title: Marek's disease in turkeys: lack of protection by vaccination.
abstract: Herpesvirus of turkeys, a highly effective vaccine against Marek's disease (MD) in chickens, was ineffective in protecting turkeys against MD. Another tissue-culture attenuated vaccine virus also protected chickens, but not turkeys, from MD. Intact and immunosuppressed turkey poults inoculated with herpesvirus of turkey developed a persistent viremia, but did not have detectable gross or microscopic lesions.
