Merck Animal Health, known as MSD Animal Health outside of the United States and Canada, a division of Merck & Co., Inc., Rahway, N.J., USA, today announced the commercial availability of CIRCUMVENT® CL vaccine, a ready-to-use vaccine formulated to protect pigs three weeks of age and older against disease caused by Porcine Circovirus (PCV) Types 2a and 2d and Lawsonia intracellularis.
CIRCUMVENT CL is designed to simplify herd health programs by delivering dual protection in a ready-to-use formulation that requires no mixing or reconstituting. This new product complements Merck Animal Health’s existing swine portfolio, including CIRCUMVENT CML, a single-dose, ready-to-use vaccine that protects against PCV Types 2a and 2d, Mycoplasma hyopneumoniae (M. hyopneumoniae) and Lawsonia intracellularis in pigs three weeks of age and older, which was introduced in 2023. CIRCUMVENT CL omits the mycoplasma component to meet the needs of herds that are now M. hyopneumoniae-negative while maintaining robust protection against PCV and Lawsonia intracellularis.
“Merck Animal Health is committed to delivering innovative, practical solutions that help veterinarians and producers protect herd health while streamlining on-farm operations,” said Brett O’Brien, V.M.D., swine technical services, Merck Animal Health. “CIRCUMVENT CL provides trusted protection against two of the most significant enteric and systemic disease agents impacting swine production in a ready-to-use formulation. By offering options such as CIRCUMVENT CML and CIRCUMVENT CL, we enable tailored vaccination strategies that simplify vaccine handling and administration.”
Key product benefits of CIRCUMVENT CL include:
- Dual protection: Effective against disease caused by Porcine Circovirus Types 2a and 2d and Lawsonia intracellularis in pigs three weeks of age or older.
- Ready-to-use: Single-bottle presentation requires no mixing or reconstituting, helping to reduce preparation time and potential handling errors.
