Three different trials on Minnesota hog farms resulting in encouraging evidence for the success of Aptimmune‘s Barricade vaccines. Dr. Chris Sievers, associate veterinarian at the Swine Vet Center in Minnesota presented on the trials at the 2018 Aptimmune Scientific Symposium.
“The exciting thing with Aptimmune is we have a vaccine that’s killed that’s showing some effectiveness,” said Sievers. “I should mention all of these were in heterogeneous challenges. It’s a different virus in the vaccine than what we had in the sow farm, and that’s a first for a killed vaccine. So not having to take a modified live product into some of our sow farms, that’s what we’re really excited about here and continue to look at the opportunity that holds.”
The trials included vaccinating sows in the face of a Porcine Reproductive and Respiratory Syndrome (PRRS) virus break, which reduced the abortion rate and helped to reduce off-feed events. Another study vaccinated weaned pigs. One trial showed a small reduction in mortality and the other showed a three percent reduction in mortality, which is significant.
Sievers said the success in small trials will lead to larger studies that will result in more comprehensive data.
