Vectormune® ND is an innovative vector vaccine which elicits an early, broad and long lasting immunity; vaccinated chickens shed significantly less virus than unvaccinated ones.

A recent publication[1] about Vectormune® ND provided the additional asset of significantly reducing the likelihood of virus transmission among birds. Indeed, a velogenic ND virus was provided with a reproduction ratio (R0) figure of 3.20 ; it basically means that 10 infected chickens are able to transmit the disease to 32 new birds, hence explaining the spreading capacity of this disease to neighboring houses; the outcome will be increased losses, including high mortality rate in case of velogenic strains. On the contrary, in Vectormune® ND-vaccinated broilers, this R0 dropped to 0.82, which means that vaccinated flocks will significantly reduce and slow down the spreading of the virus. In addition, they will survive thanks to a strong protection.

This publication helps us to understand that Vectormune® ND controls and prevents Newcastle Disease outbreaks despite of a different genotype between challenge strain and vaccine insert.

In conclusion, Vectormune® ND is a strong tool to break the uncontrolled transmission of NDV among chickens in a house, in between houses in a farm, and ultimately among farms in a high densely populated poultry area. Hence, Vectormune® ND helps to prevent and control Newcastle Disease outbreaks in poultry industry and protects the performance. By this way, Ceva Animal Health provides one more evidence towards supporting its customers to achieve their targets all around the world.
