For more than 50 years, we’ve been at the forefront of cattle vaccination, playing a crucial leadership role in the advancement of vaccine science and technology, and helping to pave the way for healthier herds.

We’re proud of the breakthroughs we’ve achieved (and those still to come), and of the cutting-edge cattle vaccines – many of which were industry firsts – that we’ve developed over the years to meet the changing needs of producers and veterinarians.

Spotlight on three standouts in our BOVILIS® cattle vaccine portfolio

Producers, talk to your veterinarian about using BOVILIS® vaccines in your vaccination protocol. Veterinarians, always read and follow the label instructions to ensure these products are suitable for the animals to be vaccinated, and contact your Merck Animal Health representative for more information, call 1-866-683-7838 or visit www.merck-animal-health.ca.



As with all vaccines, the efficacy of a product may vary depending on the animal’s current health state and its environment. Refer to bottle or carton label for additional information.

The new look of protection.

All cattle vaccines from Merck Animal Health now live under the BOVILIS® name. They’re the same vaccines – only with updated names and packaging. Each product has its own distinct color and is clearly marked, making it easy to identify each vaccine of the Bovilis line.
