MSD Animal Health Announces CIRCUMVENT® CML Takes Top S&P Global Award as the 2023 Best New Food Animal Product

The award marks the 6th year in a row for recognition in this category

Rahway, NJ, Jan. 18, 2024 – MSD Animal Health, a division of Merck & Co., Inc., Rahway, N.J., USA (NYSE:MRK), today announced CIRCUMVENT® CML has been awarded the Best New Food Animal Product from S&P Global Animal Health. It is the first and only ready-to-use, single-dose intramuscular injectable vaccine against disease caused by Porcine Circovirus Types 2a and 2d, Mycoplasma hyopneumoniae and Lawsonia intracellularis in pigs, three weeks of age or older. 

The award marks the sixth straight year for MSD Animal Health to be honored in this category. Past MSD Animal Health products that have been honored include the IDAL® portfolio technology, PORCILIS® Lawsonia intramuscular vaccine for piglets, NOBILIS® SALENVAC ETC, WHISPER® ON ARRIVAL and SENSEHUB® Feedlot. Additionally, MSD Animal Health was named Best Animal Health Company, North America in 2021.

“We are proud to continually be recognized as a leader in the animal health industry that brings together innovative solutions from our combined biopharmaceuticals and technology solutions portfolio to shape the future of animal health,” said Shannon Kellner, vice president, U.S. Livestock Business, MSD Animal Health. “Our people – from research and development to manufacturing to sales – continually strive to help our customers improve the health of their animals and bring efficiencies to their operations. CIRCUMVENT CML is another example of our pioneering science that will help the swine industry do just that.”

With CIRCUMVENT CML, veterinarians and producers have the convenience of vaccinating for three of the most important swine disease concerns, all in one bottle with no mixing or reconstituting. Also, the animals benefit from the three-way protection in one single vaccination. 

“Porcine Circovirus Type 2 is one of the most common and economically damaging viruses in the swine industry,” said Jamie Lehman, D.V.M., swine technical services veterinarian, MSD Animal Health. “The disease remains an important pathogen of growing pigs worldwide. CIRCUMVENT CML delivers efficacy against three of the most commonly identified swine diseases in one bottle – and in one vaccination. There is currently no other available injectable vaccine that combines these three pathogens in one bottle.”

For the development of this novel vaccine, MSD Animal Health sought to understand the needs of the swine industry and then shape its research and development efforts over 10 years to provide effective solutions to meet those unmet needs.

The addition of CIRCUMVENT CML broadens the company’s swine portfolio, which also includes proven products, such as CIRCUMVENT PCV-M G2 and PORCILIS® Ileitis.

This product provides several benefits to swine producers, including: 

  • Reduced injections and reduced pig handling; 
  • Less waste, reduced shipments of products and reduced refrigeration storage space. 
  • The trusted antigens used in our existing products, CIRCUMVENT PCV-M G2 and PORCILIS® Ileitis, which are proven products in the industry that for years have protected swine from disease caused by PCV2, Mycoplasma hyopneumoniae and Lawsonia intracellularis.   
  • The trusted adjuvant used in our CIRCUMVENT PCV-M and PORCILIS Ileitis vaccines, Microsol Diluvac Forte®, enhances the immune response to the antigens and increases the duration of immunity.  

“MSD Animal Health has continued its winning streak in the Best New Food Animal category by bringing differentiated products like this novel vaccine to the market. The company is continuing to build quite a reputation by winning this award multiple times, which is a testament to its innovation and customer focus within the industry,” said Joseph Harvey, head of S&P Global Animal Health. S&P Global provides essential financial information and analytics, including specific commodity coverage, to businesses globally.

In 2023, MSD Animal Health introduced CIRCUMVENT® CML, the first ready-to-use, single-dose vaccine effective against disease caused by Porcine Circovirus Types 2a and 2d, Mycoplasma hyopneumoniae and Lawsonia intracellularis in pigs, three weeks of age or older, to the swine industry. It recently has been awarded the Best New Food Animal Product from S&P Global Animal Health.
