Evolution of Influenza Vaccine Substrates

The 1930s marked the development of cultivating influenza viruses in embryonated eggs. This method dominant until the 1950s. The discovery of influenza virus growth in various cell lines (MDCK and Vero cells) in the late 1950s led to a gradual shift from embryonated eggs to cells-based vaccine production.

Antigens for WHO's Recommended Influenza Vaccine Strains

Influenza’s constant antigenic drift necessitates annual vaccine reformulation for optimal efficacy. the WHO updates the formulation of the vaccine annually to ensure the vaccine match the seasonal circulating viruses. To support Influenza vaccine research and development, ACROBiosystems has developed key reagents consistent with influenza vaccine components recommended by WHO.
