New PRRS Vaccine
Fostera PRRS from Pfizer Animal Health is a modified-live vaccine for growing pigs that adds a new weapon in the costly battle against porcine reproductive and respiratory syndrome (PRRS). Pfizer Animal Health’s research and development team made a significant breakthrough when they created a cell line able to express a newly discovered key receptor protein for the PRRS virus. “With more than half of weaning-age, PRRS-negative pigs becoming infected before going to market, this innovative vaccine option helps growing pigs defend themselves against a PRRS challenge,” says Steve Sornsen, DVM, senior director, Veterinary Business Solutions at Pfizer Animal Health. A challenge study demonstrated that Fostera PRRS, the first and only PRRS vaccine to aid in prevention of PRRS respiratory disease, reduced lung lesions by 84% and reduced overall respiratory clinical signs by 80%. Results also showed vaccination with Fostera PRRS improved average daily gain by 2.5 times compared to pigs in the placebo group. Vaccination is approved for pigs 3 weeks of age and older.
