AlHijjah 08, 1436, September 22, 2015, SPA -- The U.S. Department of Agriculture (USDA) Monday awarded its first license to develop a bird flu vaccine to an Iowa company. Harrisvaccines said that the conditional license authorizes it to continue testing the vaccine's effectiveness and stand ready if the USDA gives an order to begin manufacturing. The company's vice president, Joel Harris, said that testing with the USDA shows the virus to be 95 percent effective in adult hens and 93 percent effective in day-old chicks with one dose. Harrisvaccines creates vaccines using genetic code, eliminating the need to handle the live viruses. It says that allows the vaccine to be updated quickly if the virus mutates.
