Immunogenicity and Safety Following a Single Dose of Influenza Vaccines in Healthy Children Who Received Either One or the Other Vaccine (an Adjuvanted Sub-unit Influenza Vaccine and a Non-adjuvanted Split Virion Influenza Vaccine) in the Previous V70P2 Study

"This phase II, observer-blind, parallel groups, single center, extension study will be performed over a period of approximately 6 months in a study population of healthy children up to 48 months of age.~Up to two hundred and forty-four children (244) having previously participated in Novartis Vaccines Study V70P2 will be vaccinated with the same influenza vaccines received in the previous trial.~Each subject will receive a single vaccine dose of 0.25mL, or of 0.5mL, if aged respectively up to 35 months or 36 up to 48 months, administered intramuscularly (IM) in the deltoid muscle, preferably of the non-dominant arm."
