Infectious Bovine Rhinotracheitis (IBR) is an acute, contagious respiratory disease of cattle caused by bovine herpesvirus type 1 (BHV-1), commonly affecting the respiratory tract and the reproductive system. It is highly contagious, resulting in rapid spread of respiratory disease among young cattle. 80-90% of herds demonstrate past exposure to IBR with the presence of IBR antibodies evident on blood test5.
IBR is an acute infection which may be characterised by visible signs including sudden onset of fever, salivation, rhinitis (red, runny nose), conjunctivitis (red, watery eyes), coughing, sneezing, inappetence and difficulty breathing. If the disease is allowed to progress, respiratory distress increases, and open-mouth breathing may be evident.
Once IBR infection takes hold, secondary bacterial infection can occur (such as MH), leading to bronchopneumonia and potentially death.
Rhinogard IBR is a unique single dose intra-nasal spray specifically designed to combat IBR. What’s more, it’s an attenuated live vaccine that contains an Australian strain of IBR. Attenuated live virus vaccines work by replicating to produce an immune response without producing disease.
When administered intra-nasally, Rhinogard IBR produces a potent local immune response in the upper respiratory tract 6,7,8 as well as an antibody response in the blood (systemic immunity).
Local immune mediators present in the respiratory tract secretions of cattle are important for protection against respiratory disease caused by IBR. The concentration of these immune mediators at 3-4 days post vaccination have been found to be associated with a decline in viral replication7,8. In short, Rhinogard IBR vaccine stops the IBR infection at the site it gets into the body.
As Rhinogard IBR is delivered intra-nasally, maternal antibodies will not interfere with a calf’s response to the vaccine. Therefore, Rhinogard IBR can be given to calves at any age.9
The most comprehensive BRD vaccination program utilising Rhinogard for IBR includes the co-administration of Bovi- Shield MH-ONE for control of Mannheimia haemolytica(MH).
Both vaccines are single dose and are rapidly efficacious.
