Respiratory Efficacy of a Multivalent Marker Vaccine Against Bovine Viral Diarrhoea Virus Types 1 and 2, Infectious Bovine Rhinotracheitis Virus, Bovine Respiratory Syncytial Virus, and Bovine Parainfluenza-3 Virus in Young Calves.

ABSTRACT: Background/Objectives: A new multivalent vaccine (DIVENCE^® PENTA), containing Bovine viral diarrhoea virus (BVDV) types 1 and 2 recombinant proteins, live gE/tk double gene deleted Bovine Herpesvirus type 1 (BoHV-1 or IBR), live attenuated Bovine respiratory syncytial virus (BRSV) and inactivated parainfluenza-3 virus (PI-3) has been designed to protect cattle against the main viral pathogens associated with Bovine respiratory disease (BRD). The aim of this study was to demonstrate the efficacy of DIVENCE^® PENTA against experimental infections with BVDV-1, BVDV-2, IBR, BRSV and PI-3 in young calves. Methods: Ten-week-old calves were given two intramuscular doses three weeks apart. The efficacy was evaluated by means of an experimental challenge three wee
