Sanofi Pasteur is seeking FDA licensure of Fluzone Quadrivalent Influenza Virus Vaccine for active immunization of children and adults ≥6 months of age for the prevention of influenza disease caused by influenza virus subtypes A and types B contained in the vaccine. This is the same age indication for the currently licensed trivalent Fluzone influenza virus vaccine.
