Subjects aged between 18 and 47 months received the GSK2321138A. "Primed" subjects (subjects who had received a 2-dose priming immunization with Fluarix™ vaccine in study NCT00764790 - or the GSK2321138A-Primed Group) received 1 dose of GSK2321138A vaccine at Day 0. "Unprimed" subject (subjects who had not received any 2-dose priming influenza immunization in any previous year - or the the GSK2321138A-Unprimed Group) received 2 doses of GSK2321138A vaccine at Days 0 and 28. The GSK2321138A vaccine was administered intramuscularly in the deltoid of the right arm.
Subjects aged between 18 and 47 months received the Fluarix™ vaccine. "Primed" subjects (subjects who had received a 2-dose priming immunization with Fluarix™ vaccine in study NCT00764790 - or the Fluarix-Primed Group) received 1 dose of Fluarix™ vaccine at Day 0. "Unprimed" subject (subjects who had not received any 2-dose priming influenza immunization in any previous year - or the the Fluarix-Unprimed Group) received 2 doses of Fluarix™ vaccine at Days 0 and 28. The Fluarix™ vaccine was administered intramuscularly in the deltoid of the right arm.
