CIRCUMVENT® CL vaccine is a new addition to Merck Animal Health’s swine portfolio. The ready-to-use vaccine is formulated to protect pigs three weeks of age and older against disease caused by Porcine Circovirus Types 2a and 2d and Lawsonia intracellularis. The formulation eliminates mixing/reconstituting, reducing on-farm labor and potential handling errors.
