Influenza virus subunit vaccine is a high-purity influenza vaccine prepared by using new cleavage technology and purification technology on the basis of influenza cleavage vaccine. Compared with the traditional influenza vaccine, the biggest advantage is to further remove the miscellaneous protein, retain only the antigen with immunogenicity, and improve the antigen purity to more than 85%. Therefore, the vaccination has low side effects, rapid antibody rise, long maintenance time, good immune effect and higher biological safety. In addition, the advanced imported multi section needle syringe is selected for the floroc pre filling syringe, which greatly reduces the pain during vaccination.
