    Area of Science:

    • Virology
    • Immunology
    • Vaccinology

    Background:

    • Influenza virus pathogenesis involves hemagglutinin and neuraminidase, but other factors also contribute to disease.
    • Existing vaccine strategies include killed or attenuated virus preparations.

    Purpose of the Study:

    • To review the significance of viral components and antibodies in influenza.
    • To discuss advancements in influenza vaccine development, including novel viral strains and mutants.

    Main Methods:

    • Review of existing literature on influenza virus structure and function.
    • Discussion of vaccine strategies: killed/attenuated viruses, antigenic recombinants, and master strains.
    • Focus on temperature-sensitive (ts) mutants, their genetic properties, and protective efficacy.

    Main Results:

    • Hemagglutinin and neuraminidase are key, but not the sole, determinants of influenza.
    • Temperature-sensitive (ts) mutants demonstrate genetic stability, transmissibility, and protection against wild strains.
    • A developed virus strain shows significant advantages, warranting further research.

    Conclusions:

    • Continued research is essential to further enhance influenza virus vaccine qualities.
    • Novel approaches like ts mutants and master strains offer promising avenues for influenza control.
    • Understanding viral components is crucial for effective vaccine design.
