Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the safety and tolerability of 1 or 2 intramuscular doses (administered 4 weeks apart) of either the cell culture-derived influenza vaccine TIVc or the egg-derived influenza vaccine TIV in children and adolescents 3 to <18 years of age at risk for influenza-related complications.;Secondary Objective: This study has no secondary objectives.;Primary end point(s): The primary endpoint for this study is safety: proportion of subjects reporting solicited AEs (including local and systemic and other solicited AEs); proportion of subjects reporting unsolicited AEs; proportion of subjects reporting SAEs, new onset of chronic diseases, medically attended AEs, and AEs leading to vaccine/study withdrawal;Timepoint(s) of evaluation of this end point: - Solicited adverse events: day of vaccination and the following 6 days (day 1 to day 7 and day 29 to day 35–the latter only for not previously vaccinated subjects); - Unsolicited adverse events: AEs occurring for approximately 3 to 4 weeks after each vaccination (ie, from day 1 to day 28; and from day 29 to day 49–the latter only for not previously vaccinated subjects); - SAEs, new onset of chronic diseases, medically attended AEs, and AEs leading to vaccine/study withdrawal: up to day 213 for “not previously vaccinated” subjects 3 to <9 years or up to day 183 for all other subjects.
