Porcine Circovirus Swine Vaccine is a single-dose PCV2 vaccine, used for the vaccination of healthy, susceptible pigs 3 weeks of age or older as an aid in the prevention of lymphoid depletion, inflammation and colonization of lymphoid tissue, and as an aid in reduction of the magnitude of viremia associated with PCV2.
