US - Zoetis Inc. has announced that the US Department of Agriculture (USDA) has granted a conditional licence for a vaccine to help fight porcine epidemic diarrhea virus (PEDv) in pigs.
The two-dose inactivated vaccine, licensed for use in healthy pregnant sows and gilts, is designed to help them develop antibodies that can be transmitted to their newborn piglets. Zoetis anticipates the vaccine will be available to veterinarians and pork producers later in September.
“This vaccine is an important part of our commitment to working with veterinarians and pork producers to help minimise the impact of PEDv on pigs in their care,” said Gloria Basse, vice president, US Pork Business Unit, Zoetis.
“To achieve the best possible results, producers should work closely with their veterinarians and the Zoetis technical services team to implement the new vaccine into their biosecurity programs.”
The vaccine is given as a 2mL intramuscular (IM) injection to sows or gilts prior to farrowing. Two doses given three weeks apart are recommended, with the second dose given two weeks pre-farrowing. Previously vaccinated sows should receive a single dose given two weeks before farrowing.
To receive the conditional license, the vaccine was shown to be safe in a field safety study, and a reasonable expectation of efficacy was demonstrated. Zoetis is working to complete the studies necessary to obtain full licensure in the United States.
“We at Zoetis are proud to provide our customers with a vaccine to help battle this devastating disease,” said Catherine Knupp, executive vice president and president, Zoetis Research and Development.
“Bringing this vaccine to market quickly — in a little more than a year since the disease was identified — exemplifies our commitment to supporting veterinarians and livestock producers with high-quality vaccines to rapidly respond to and help control the evolving and complex threat of emerging infectious diseases.”
Zoetis continues work with Iowa State University on a second vaccine approach to help control PEDv.
The results from these vaccine research programs could have applicability in countries outside the US where PEDv has been identified and is threatening swine herds and the livelihoods of producers.
“From death loss to employee morale, we know the impact PEDv has had on the swine industry over the past 15 months,” said Rick Swalla, DVM, Pork Technical Services, Zoetis. “We look forward to bringing solutions to and working with veterinarians and producers to help combat this disease.”
In the meantime, ongoing efforts to slow the spread of PEDv continue to focus on improving biosecurity measures. From the farm to transport trucks, stepped-up efforts include additional sanitation, better control of access points and review of employee protocols. All of these steps have been demonstrated to help mitigate the risk of the virus entering a farm.
