Population Immunity to Influenza Neuraminidase: From Immune Imprinting to Pandemic Preparedness
Neuraminidase (NA) is a major surface glycoprotein of influenza viruses that mediates the release of progeny virions from infected cells. Although both hemagglutinin (HA) and NA are targets of protective immune responses, current seasonal influenza vaccines are primarily standardized based on HA content, resulting in v...
