The vaccine antigen components are selected from the surface antigens of currently prevalent influenza virus strains, such as hemagglutinin (HA) and neuraminidase (NA). High-purity influenza virus antigens are prepared through cell culture or recombinant DNA technology. For example, influenza virus is cultured using Madin-Darby canine kidney (MDCK) cells, and purified through centrifugation, filtration, and chromatography to obtain high-purity HA and NA antigens. After injection into the human body, the influenza virus antigens (HA and NA) are taken up and processed by antigen-presenting cells (such as macrophages and dendritic cells). The antigen-presenting cells present antigen peptides to T lymphocytes and B lymphocytes, activating a specific immune response. B lymphocytes differentiate into plasma cells with the help of T lymphocytes, producing specific antibodies that recognize and bind to the influenza virus, preventing it from infecting host cells and thus preventing influenza virus infection.
