Researchers at the US Department of Agriculture's Agricultural Research Service have developed a vaccine against African Swine Fever (ASF), a disease that has severely impacted pig herds in Asia, particularly in China. The vaccine, which has shown to prevent and protect both European and Asian bred swine against the Asian strain of the virus, is now ready for commercial trials. The vaccine, developed through genetic modification, could have a global impact as ASF has caused significant economic losses to the swine industry. The vaccine has shown to achieve full protection in swine by the fourth week post-vaccination. The researchers are now determining the safety and efficacy of the vaccine under commercial production conditions and are working with a commercial partner in Vietnam for its commercialization.
