Huier Kangxin® extracts only effective antigens, featuring high purity, low vaccination side effects, excellent safety profile, and comprehensive protection, and is classified as a Category 1 preventive biological product. The clinical trial results all reached the primary endpoints and were published in the international authoritative journal Vaccine, and were cited by the Technical Guidelines for Influenza Vaccination in China (2021-2022) and Technical Guidelines for Influenza Vaccination in China (2022-2023) respectively.
Clinical results show that Huier Kangxin® is a safe and effective influenza vaccine that can provide broader and more robust protection against seasonal influenza viruses. The vaccine is expected to serve as an important component of influenza prevention strategies and contribute to global influenza prevention and control efforts.
