Since hemagglutinin is the major surface protein of the influenza A virus and is essential to the entry process, it is the primary target of neutralizing antibodies. These antibodies against flu have been found to act by two different mechanisms, mirroring the dual functions of hemagglutinin: Some antibodies against hemagglutinin act by inhibiting attachment. This is because these antibodies bind near the top of the hemagglutinin "head" (blue region in figure above) and physi…
