Greenfield – based Elanco Animal Health introduces new respiratory PRRS vaccine

Elanco Animal Health, a division of Eli Lilly and Company (NYSE: LLY), today announces licensing of Prevacent® PRRS by the USDA, a modified-live respiratory vaccine that has been shown to be effective in the reduction of porcine reproductive and respiratory syndrome (PRRS), respiratory form, in piglets two weeks or older.

Since its emergence in the late 1980s, PRRS has cost the swine industry millions annually in respiratory disease in piglets and reproductive failure in sows.

“PRRS has grown to be a costly and challenging disease that is difficult to control at the local, regional and national levels,” says Chris Chavis, senior director, Elanco North America Food Animal Business. “We are eager to bring producers a new product to tackle this devastating disease.”

Currently, it is estimated that PRRS costs the swine industry $560 to $660 million annually, with the breeding herd costs accounting for 45 percent of the total industry cost.1

“Elanco is excited to be able to provide producers and the entire swine industry with a new product that is proven effective against the respiratory form of PRRS,” says Chavis. “Not only is it safe to use in piglets two weeks or older, Prevacent PRRS has a demonstrated duration of immunity of 26 weeks for the respiratory form of PRRS.”

The viral strain in Prevacent PRRS is highly relevant to today’s swine operations so producers can be confident that they are getting effective protection against the respiratory form of PRRS for their piglets.

“The contemporary strain in Prevacent PRRS demonstrated cross protection against multiple difficult viral strains that may pose a threat to swine operations. Prevacent PRRS is a timely and effective solution for to meet the PRRS challenges producers are facing today,” says Chavis.

Prevacent PRRS is a key part of Elanco’s Full Value Pigs®, which includes a complete portfolio of products that help to control specific enteric and respiratory diseases.
