Study of the joint administration of HIPRAVIAR® SHS with respiratory vaccines for preventing Newcastle Disease and infectious bronchitis

The need to reduce the number of days of vaccination in broiler flocks has led to the proposal of studies for defining the possible joint administration of a vaccine for preventing avian pneumovirus vaccine and other types of respiratory vaccines. Up to now, these vaccines have been administered separately in order to minimize interaction between them. In principle, the fact that they all compete for the same receptors would imply that there would be interaction between them and, in the end, the protection afforded against pneumovirus could be affected.
