Merck Animal Health introduces Once PMH® IN, the only intranasal vaccine to deliver dual bacterial pneumonia protection in healthy beef and dairy cattle, including calves as young as 1 week of age. Once PMH IN aids in the control of respiratory disease caused by Mannheimia haemolytica and prevention of disease caused by Pasteurella multocida – the leading causes of early-onset bovine respiratory disease (BRD).

Available in 10- and 50-dose packages, Once PMH IN is a non-adjuvanted formulation with two dosing options – 1 mL applied in each nostril of the animal, or a 2-mL dose delivered in one nostril. Because there is no vaccine injection site, carcass quality is not compromised. While annual revaccination is recommended, the vaccine can be administered more frequently, depending on the risk assessment for the farm or herd.
