Summary

This is a study to assess the immune (antibody) response and safety of a Seqirus split virion, inactivated Quadrivalent Influenza Vaccine (Seqirus QIV), in comparison with a US licensed 2016/2017 Quadrivalent Influenza Vaccine (comparator QIV) in a healthy pediatric population 6 months through 59 months of age.

• Influenza, Human

Interventions

Type	Name	Description
BIOLOGICAL	Seqirus Quadrivalent Inactivated Influenza Vaccine	The Seqirus study vaccine is a sterile, thimerosal-free suspension containing 60 mcg total hemagglutinin antigen per 0.5 mL (15 mcg each of the four recommended influenza strains for the Northern Hemisphere 2016/2017 influenza season). Subjects will receive one or two doses according to the recommendations of the Advisory Committee on Immunization Practices for the United States 2016-17 Influenza Season. Preferred sites for intramuscular injection are the anterolateral aspect of the thigh in infants 6 months through 11 months of age, the anterolateral aspect of the thigh (or the deltoid muscle of the arm if muscle mass is adequate) in children 12 months through 35 months of age.
BIOLOGICAL	Comparator Quadrivalent Inactivated Influenza Vaccine	The comparator Quadrivalent Inactivated Influenza vaccine is a US-licensed product containing four recommended influenza strains for the Northern Hemisphere 2016/2017 influenza season. Subjects will receive one or two doses according to the recommendations of the Advisory Committee on Immunization Practices for the United States 2016-17 Influenza Season. Preferred sites for intramuscular injection of the non-dominant arm in children 36 months through 59 months of age.
