Intranasal cattle vaccine combines five doses to simplify vaccination


A relatively new vaccine for cattle from Merck Animal Health is combining both bacterial and viral protection in one intranasal dose, reducing the number of instances producers have to administer vaccines to each animal.

Bovilis Nasalgen 3-PMH, simply called Nasalgen, has been on the market for roughly one year and combines three virals and two bacterials into one vaccine that’s administered nasally, explains Lee Sinclair, sales rep for Merck, noting the intranasal method provide some important benefits over traditional intravenous methods.

“So traditional injectables, if those calves are too young at turnout time when they go to grass, mom’s maternal antibodies with an injectable vaccine can sometimes override those viral components, whereas an intranasal vaccine bypasses the maternal antibodies. So we get a better, quicker pickup by the calves and a better response from the vaccine,” he says.

Nasalgen provides protection against IBR, BRSV, PI3, Pasteurella multocida and Mannheimia haemolytica.

Although virals and bacterial have been combined before through intravenous applications, Sinclair says this is the first intranasal vaccine that combines all five in one dose.
