Key result
Evolving virulent Marek's disease virus strains reduce commercial vaccine protection to as low as ~28%.
Why the study?
Despite widespread vaccination, Marek's disease still leads to severe economic losses, and continuous evolution of virulent strains threatens vaccine efficacy, warranting a review of recent scientific data.
Continuous evolution of highly virulent Marek's disease virus strains threatens current vaccine efficacy in poultry, necessitating improved molecular surveillance and vaccine platforms.

Warrants enhanced surveillance and novel vaccine platforms in poultry; challenges reliance on current commercial formulations.
Isam Azeez Khaleefah (2026) conducted a review in Marek's disease. The continuous evolution of highly virulent Marek's disease virus strains has reduced the protective index of commercial vaccines to as low as 28-50% in recent challenges.
