USDA grants license for PEDv vaccine

WASHINGTON, D.C. — The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service recently issued a conditional license to Harrisvaccines, of Ames, Iowa, for a vaccine that may aid in the control of porcine epidemic diarrhea virus (PEDv) in swine.

This is the first licensed vaccine for PEDv. It will be used to vaccinate sows with the intent that they build antibody, and transmit that antibody through their milk to newborn piglets. It is intended to protect the piglets against PEDv.

Porcine epidemic diarrhea is a disease that causes significant sickness in swine, affecting their growth and health, and causes high mortality in piglets. The disease is common in parts of Asia and Europe, but is not reportable to the World Organization for Animal Heal.

PEDv only affects pigs and does not pose any risk to people or pets. It is not a food safety concern.
