Prof. Chen Hualan and her team at the Harbin Veterinary Research Institute of CAAS developed a H5/H7 bivalent avian influenza inactivated vaccine. The vaccine can effectively stop the spread of H7N9 avian influenza viruses in poultry and block the human infection with H7N9 virus in China. The successful prevention and control of H7N9 infection has become a model case of controlling zoonosis from animal sources in China.
