Vaccine against Newcastle disease
Clinical protection and to prevent excretion
Context
Newcastle disease is one of the most deadly diseases for farmed birds, sometimes killing up to 100% of a given population. The disease is prevalent around the entire world, with considerable impact on southern countries, and forcing northern countries to engage in continuous prevention via vaccines, while monitoring farms permanently. The vaccines against Newcastle disease currently available in the worldwide market are mainly attenuated strains derived from old genotypes. These vaccines continue to protect against the clinical expression induced by infection from strains circulating today. However, it has been shown that they no longer prevent the virus's multiplication or its transmission to other sensitive birds.Benefits
Development of a new vaccine that is efficient against most of the identified genotypes of the virus causing Newcastle disease, able to protect threatened aviary species both clinically (no symptoms) and virologically (stopping viral shedding).Applications
Vaccination for poultry farms around the world, notably in Asia, to fight effectively against this disease and prevent its expansion.AVAILABLE TECHNOLOGY I Vaccine – Farms
