Seasonal flu (influenza) is a common infectious disease of the respiratory tract causing mild to severe illness. Vaccination is the most effective way to prevent seasonal flu. Each year, 3-4 different flu strains will be selected as vaccine strains based on surveillance data of the recent isolates, and the performance of the vaccines from the previous season.
|
|
The annual vaccine strains normally include both influenza A and influenza B. There are many subtypes of influenza A based on the subtype of two surface antigens, hemagglutinin (HA) and neuraminidase (NA), while influenza B is divided into two lineages, the Yamagata lineage, and the Victoria lineage.
|
|
To support influenza research, Sino Biological has developed a panel of recombinant antigen products covering most of the vaccine strains from 2015-2020. The products include both HA and NA proteins, and some nucleoprotein (NP) proteins. Customized production is available if your antigen (or strain) of interest is not on the current list.
