Overview
The influenza virus split vaccine developed by Beijing Zhifei Green Bamboo Biopharmaceutical is an inactivated vaccine designed to provide active immunization against seasonal influenza. Produced using a split-virion platform, the vaccine contains purified antigens, primarily hemagglutinin (HA), from influenza A (H1N1 and H3N2) and influenza B virus strains. The 'split' process involves treating the virus with detergents or solvents to disrupt the viral envelope, which reduces the risk of adverse reactions compared to whole-virus vaccines while maintaining high immunogenicity. It is typically administered via intramuscular injection and is intended for use in both children and adults to prevent morbidity and mortality associated with annual influenza outbreaks. The vaccine is manufactured by Beijing Zhifei Green Bamboo Biopharmaceutical, a subsidiary of Chongqing Zhifei Biological Products.
