For years, conventional wisdom held that vaccinating newborn calves didn't produce much in the way of a positive benefit and, in fact, interfered with maternal antibodies in the colostrum. However, research indicates the bovine fetus has a much more mature immune system than originally believed.

In fact, the immune system of the fetus is functional at about 170 days of gestation, and immune development in the fetus is independent of antibody production. That means the immune system can respond to an appropriately delivered vaccine without antibody interference.

Using this research as a springboard, Intervet/Schering-Plough Animal Health developed Onset 5 Intranasal (IN) vaccine, a five-way modified-live vaccine that can be given to healthy calves shortly after birth.

Intranasal vaccination more closely mirrors the route of real-world infection - more than 95% of disease-causing agents enter through the nose, causing primary respiratory disease and often secondary infection, according to Scott Nordstrom, Intervet manager of veterinary technical services. When delivered to the mucosal surfaces inside the nose, the calf can more quickly develop an immune response.

“The safety and efficacy trials also revealed two very interesting and positive side effects,” he says. “We learned that intranasal administration shuts down viral shedding and has no impact on the white blood count or platelets of the animal.”

For beef operations, Onset 5 IN may be utilized for calves 3-8 days of age and older. Used in young calves, it primes the immune system, helping set the animal up for a more effective cell-mediated immune response and subsequently more robust long-term immunity, Intervet says.

It can also be used at branding or weaning, with newly arrived stocker or feeder cattle to induce a rapid immunological response in the face of high stress, and as a preventive measure pre-shipment. It can be used in combination with subcutaneous vaccinations in a VAC 45 preconditioning program that calls for two vaccinations, Nordstrom says.

Because intranasal vaccination doesn't use a needle, it fits well in a BQA program. With no injection site, carcass quality isn't compromised. Vaccination consists of a 2-mL dose in one nostril or a 1-mL dose into each nostril.
