Animal health company Boehringer Ingelheim has launched an intranasal vaccine for calves.
Bovalto Respi Intranasal protects against the two main respiratory viruses – RSV and PI3.
The vaccine triggers mucosal immunity in the nasal passages and throat area.
Bovalto Respi Intranasal should be delivered as a single shot, from 10 days of age and provides immunity for 12 weeks, from 10 days after vaccination.
To assist with effective administration, there is a Bovalto Respisafe applicator and nozzle, which fits against the calf’s nostril, and a vaccinator.
Correct administration will ensure that the spray is delivered in the most efficient manner to do its job, says the manufacturer.
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 back of the throat and is wasted.
It can be obtained through vets. Price is available on request.
