Serum titers of swine immunized with chimeric virus BVP1. Groups of swine were immunized with 0.5 mg (â–²), 5 mg (â—†), 10 mg (â– ) of chimeric virus BVP1 or 5 mg of wild-type virus BaMV-S (â—‹) or PBS (â–¡). Swine sera were collected at the indicated time after immunization. Anti-VP1 titers were determined by ELISA. The animals inoculated with 0.5 mg BVP1 were boosted with the same amount of BVP1 four weeks after priming while those inoculated with 5 mg and 10 mg of BVP1 were boosted six weeks after priming.
