Ohio State Researcher Develops Innovative Vaccine
An Ohio State University researcher has created a unique vaccine to protect swine from porcine reproductive and respiratory syndrome (PRRS), a viral disease that causes direct losses to U.S. swine producers to the tune of $664 million a year.
In Ohio, which ranks ninth in the U.S. in overall pork production, outbreaks of PRRS have been more common since 2010. Even among vaccinated sow herds in the state, the virus can cause 10-20 percent mortality, a significant economic loss for an industry worth $681.5 million in production value alone and that supports 10,000 jobs.
Unlike the current live vaccines used to prevent PRRS, the new vaccine uses an inactivated virus to eliminate adverse reactions in pigs such as abortion, sick piglets and further spread of the disease, said Renukaradhya (Aradhya) Gourapura, an associate professor in the university's Food Animal Health Research Program, part of the Ohio Agricultural Research and Development Center.
