New streamlined production methods have been brought into use by Zoetis to ensure reliable supplies of its Marek’s disease vaccine.
Poulvac CVI + HVT Marek’s vaccine provides the combination of the Rispens CVI strain and the HVT strain. This combination of serotypes has long been recognised for providing strong, reliable protection against the disease, effective even against the very virulent pathotype of the virus.
“Marek’s disease remains a major problem for the poultry industry,” said John Kenyon, Zoetis national veterinary manager for poultry.
“To increase protection, it is a good idea to combine the CVI and HVT vaccine strains, and the new supplies of our vaccine help to make this more feasible.
“Currently in some longer-lived broilers and backyard laying hens a vaccine composed of just a single serotype is used, but it is advantageous to use a combination of serotypes to boost immunity further.”
Marek’s vaccination with Poulvac CVI + HVT can be performed in the hatchery at day of age via subcutaneous or intramuscular injection.
