A vaccine for a disease that began impacting the pork industry a year ago has received a conditional license. The vaccine developed by Iowa based Harrisvaccines is the first to be granted the license by the United States Department of Agriculture to treat Porcine Epidemic Diarrhea virus (PEDv). According to Joel Harris, representative for the company, the vaccine is being used to boost immunity in herds that have suffered PEDv outbreaks.
He shares the field data they have isn’t controlled, meaning evidence of its effectiveness is anecdotal, but they are seeing a reduction in pre weaning mortality in operations that use the vaccine and improve their bio-security. He adds they’re now looking into whether the vaccine can help prevent the disease as well.
The National Pork Board estimates the disease killed up to 8 million pigs between June 2013 and April 2014.
