USDA's Agricultural Research Service (ARS), along with the Department of Homeland Security and GenVec Inc., have developed the first foot-and-mouth disease (FMD) vaccine produced in the U.S. While FMD vaccines already exist, the new vaccine, still under development, is a molecular-based product that doesn't require expensive, high-containment production facilities. The new vaccine also makes it possible to determine whether an animal with FMD antibodies acquired them via disease or vaccination. Additional testing is underway to determine the product's commercial viability and effectiveness against various FMD serotypes.
