Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

Deletion of the Viral Thymidine Kinase in a Meq-Deleted Recombinant Marek’s Disease Virus Reduces Lymphoid Atrophy but Is Less Protective

Microorganisms, 2021
Marek’s disease (MD) is a ubiquitous disease of domesticated chickens and its etiologic agent is the Gallid alphaherpesvirus 2 (GaHV-2), also known as Marek’s disease virus (MDV). MD is currently controlled by vaccination using live attenuated strains of

The epizootiology of Marek's disease 3. The interrelationship of virus pathogenicity, antibody and the incidence of Marek's disease [PDF]

Avian Pathology, 1976
Approximately 1000 day-old White Leghorn chickens were distributed into 5 pens in a brooder house and exposed to natural infection with Marek's disease virus (MDV). Observations were made on the inter-relationship between strains of MDV infecting the chickens, precipitating antibody, incidence of Marek's disease (MD), body weight, egg production, feed ...

Chicken anaemia virus influences the pathogenesis of Marek's disease in experimental infections, depending on the dose of Marek's disease virus [PDF]

Veterinary Quarterly, 1993
Eight groups of 1-day-old chickens were inoculated with 0, 250, 5000, or 100,000 white blood cells of chickens infected with Marek's disease virus strain K (MDV-WBC). Four of these groups were additionally infected with 10(5) TCID50 chicken anaemia virus (CAV).
