The USDA has granted Zoetis a conditional license for a vaccine to help fight porcine epidemic diarrhea virus (PEDv) in pigs. The license allows the vaccine to be used in healthy pregnant sows and gilts and is designed to help them develop antibodies that are transmitted to newborn piglets. Zoetis anticipates the vaccine will be available later in September.
This is the second conditional license for such a vaccine. Harrisvaccines, was granted conditional approval from the USDA for its vaccine in June.
In the meantime, efforts to slow the spread of PEDv continue to focus on biosecurity. Stepped-up efforts include sanitation, controlling access points and reviewing employee protocols. All of these steps have been demonstrated to help mitigate the risk of the virus entering a farm.
