Andrew Montgomery, veterinary adviser for MSD Animal Health, says this is a very positive outcome for the industry: "It is estimated that 90% of UK herds have been exposed to bovine viral diarrhoea1 (BVD), costing the UK cattle industry up to £61 million each year2."
The new Summary of Product Characteristics for Bovilis BVD states that following primary immunisation, consisting of two vaccinations given 4 weeks apart to cattle over the age of 8 months, and a further vaccination 6 months after this, revaccinations can be given at up to 12 month intervals.
Andrew said: "The fundamental principle of control, is to identify and remove persistently infected (PI) animals from a herd, and stop PIs being created using a trusted and proven vaccine.
"Providing primary immunisation has been finalised 4 weeks before the start of gestation, Bovilis BVD is licensed to protect the foetus against transplacental infection, preventing the creation of a PI calf which is hugely significant for BVD control.
"The convenience of being able to vaccinate on a herd level without having to assess pregnant animals on a case-by-case basis provides the flexibility to tailor vaccination schedules to the farm system, which for many vets and farmers comes as a convenient solution."
MSD says Bovilis BVD also has the advantage of not interfering with antigen ELISA or PCR testing and can be jointly administered with other routine vaccines.
For example, Bovilis BVD can be mixed and administered with Bovilis® IBR Marker Live when given as a booster dose to cattle from 15 months of age, or can be administered on the same day as Leptavoid-H in cattle from 8 months of age.
