Recombinant flu vaccines do not require having a candidate vaccine virus (CVV) sample to produce. The field of vaccine technology has come a long way since the invention of the first vaccine over 200 years ago. These novel technologies can be used for both IIV and LAIV candidates, abolish the need for time-consuming classical reassortment and could significantly shorten their production time. A homotrimeric viral surface glycoprotein that mediates the attachment of influenza viruses to cells by binding to sialic acids on glycan structures of cellular receptors. Which of these technological advances has improved flu vaccines near me. Specifically, the 22–23-amino-acid short ectodomain of M2 (M2e) is promising because of its high conservation and surface exposure 200. Importantly, novel potency assays and correlates of protection have to be established for these vaccine candidates because current assays and correlates are focused on globular-head-directed immunity. Margine, I., Martinez-Gil, L., Chou, Y. CNN [online], (2014). Chimeric haemagglutinins are fully functional, and recombinant influenza viruses expressing them grow to high titres in embryonated eggs and in cell cultures 175.
