Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: GSK2282512A Group; Subjects aged between 6 to 35 months inclusive received 1 dose (primed subjects) at Day 0 and 2 doses (unprimed subjects) at Days 0 and 28 of quadrivalent influenza GSK2282512A vaccine. Quadrivalent influenza GSK2282512A vaccine was administered intramuscularly in the left anterolateral thigh (subjects < 12 months of age) or the deltoid muscle (subjects ≥ 12 months of age).	Biological: Quadrivalent influenza GSK2282512A vaccine; 1 or 2 doses administered intramuscularly (IM) in deltoid muscle or anterolateral thigh on Day 0 (primed subjects) and on Day 0 and Day 28 (unprimed subjects) respectively.
Active Comparator: Fluarix Group; Subjects aged between 6 to 35 months inclusive received 1 dose (primed subjects) at Day 0 and 2 doses (unprimed subjects) at Days 0 and 28 of Fluarix vaccine. Fluarix vaccine was administered intramuscularly in the left anterolateral thigh (subjects < 12 months of age) or the deltoid muscle (subjects ≥ 12 months of age).	Biological: Fluarix; 1 or 2 doses administered IM in deltoid muscle or anterolateral thigh, on Day 0 (primed subjects) and on Day 0 and Day 28 (unprimed subjects) respectively.

Primary Outcome Measures

Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms.	Solicited local symptoms assessed were pain, redness and swelling. Any was defined as occurrence of the specified solicited local symptom regardless of its intensity. Grade 3 pain was defined as pain that prevented normal everyday activities.

Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms (Excluding Fever).	Solicited general symptoms assessed were drowsiness, irritability/fussiness and loss of appetite. Any was defined as any solicited general symptom reported irrespective of intensity and relationship to vaccination. Related was defined as symptoms assessed by the investigator to have a causal relationship to vaccination. Grade 3 irritability/fussiness was defined as crying that could not be comforted/prevented normal activity. Grade 3 loss of appetite was defined as not eating at all. Grade 3 drowsiness was defined as drowsiness that prevented normal activity.	During the 7-day (Days 0-6) post-vaccination period
