Single-component self-assembling protein nanoparticles displaying stabilized prefusion-closed hemagglutinin trimers for influenza vaccine development
Current influenza vaccines primarily target hemagglutinin (HA), the major viral surface glycoprotein and principal determinant of neutralizing antibody (NAb) responses. However, antigenic drift and shift, together with HA’s intrinsic metastability and low-pH sensitivity, limit broad and durable vaccine protection. Here...
