influenza A virus neuraminidase

Introduction

One of two major influenza A virus surface proteins (also see influenza A virus hemagglutinin). These two proteins mutate rapidly. Current (1999) vaccines are directed against these two proteins neuraminidase & hemagglutinin. Thus influenza A vaccines must be produced each year based upon the most recent strains of virus.
