Conserved epitope on influenza-virus hemagglutinin head defined by a vaccine-induced antibody

Abstract excerpt

Circulating influenza viruses evade neutralization in their human hosts by acquiring escape mutations at epitopes of prevalent antibodies. A goal for next-generation influenza vaccines is to reduce escape likelihood by selectively eliciting antibodies recognizing conserved surfaces on the viral hemagglutinin (HA). The receptor-binding site (RBS) on the HA "head" and a region near the fusion peptide on the HA...
