Annually influenza virus infections are responsible for hospitalization and mortality, especially in high risk groups. Constant antigenic changes in seasonal influenza viruses resulted from antigenic shifts and antigenic drifts, enable emerging of novel virus subtypes that may reduce current vaccine efficacy and impose the continuous revision of vaccine component. Currently available vaccines are usually limited by their production processes in terms of rapid adaptation to new circulating subtypes in high quantities meeting the global demand. Thus, new approaches to rapidly manufacture high yields of influenza vaccines are required. New technologies to reach maximal protection with minimal vaccine doses also need to be developed.
