Vaccine launched to help in fight against calf pneumonia

REDUCE, refine and replace are at the heart of RUMA’s (Responsible Use of Medicines in Agriculture Alliance) ‘One Year On’ report, which was published at the end of 2018, acknowledging that the UK farming industry has achieved a 40 per cent reduction in antibiotic use in the five years to 2018. Information on how each sector is performing shows mixed progress.

Within the dairy and beef sectors, calf rearing had been identified as a ‘hot spot’ of treatment and a stage in the animal’s life where antibiotics could be used more appropriately and vaccination more widely integrated into herd management protocols.

Offering farmers more choice and the opportunity to protect very young calves, Bovalto Respi Intranasal has been launched by Boehringer Ingelheim Animal Health – an intranasal vaccine for calves that can be used from 10 days of age. The use of pneumonia vaccines in calves and youngstock will serve to reduce disease rates, so cutting antibiotic use.

Bovalto Respi Intranasal protects against the two main respiratory viruses – RSV and PI3, and during its development the virus components were tested against recently circulating virus strains.

Being an intranasal vaccine, it triggers mucosal immunity in the nasal passages and throat area. There is an extensive immune system in this area in cattle, so priming it with a vaccine such as this delivers fast, effective, predictable protection.

Bovalto Respi Intranasal is delivered as a single shot, from 10 days of age and provides immunity in the face of MDA (maternally derived antibodies).

In order to assist with effective administration, a dedicated delivery pack for use has been developed. This includes the Bovalto Respisafe applicator and nozzle which fits against the calf’s nostril, along with a vaccinator.

“The aim is to make sure that vac-

cination is a comfortable process for both farmer and calf, as well as addressing concerns on the admin-

istration of vaccine to the approp-riate area in the nasal passages,” says Matt Yarnall, vet and brand manager at Boehringer Ingelheim.

“Correct administration of the vaccine will ensure that the spray is delivered in the most efficient manner to do its job. If the droplet size is too big, then it can run out of the nose, and if too small then this is carried into the lungs and is wasted.”

“Time and money is spent vaccinating calves and so the process needs to be effective to give optimal protection,” concludes Mr Yarnall. “If adding to the Bovalto range encourages more farmers to vaccinate against pneumonia, so improving calf heath and lowering antibiotic use, that can only be a step in the right direction.”
