Safety and Immunogenicity Study of QIVc in Healthy Pediatric Subjects
InfluenzaHuman1 moreThis phase 3 clinical study is a randomized, observer-blind, comparator-controlled, multicenter study of QIVc versus a US-licensed comparator QIV in children 6 months through 47 months of age. The purpose of this study is to demonstrate that vaccination with QIVc elicits an immune response that is noninferior to that of a US-licensed comparator QIV containing the same virus strains, in children 6 months through 47 months of age.

InfluenzaHumanThis Phase 2, randomized, observer-blind, dose-confirmation Clinical study is evaluating different formulations of MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine. Approximately 1000 subjects are to be randomized into 1 of 4 possible treatment groups with 250 participants per group. Every participant will receive an influenza vaccine injection on Day 1 and will be followed up for approximately 6 months following injection. The primary immunogenicity analysis is based on Day 29 serology data.

A Study of a Seasonal Trivalent Split, Inactivated Influenza Vaccine
InfluenzaHumanThis is a phase I, double-blind, randomized, placebo-controlled trial with two groups of participants to receive seasonal trivalent split, inactivated influenza vaccine (A/H1N1; A/H3N2 and B) or placebo (phosphate buffered saline). A total of 60 healthy male and female adults 18 through 45 years of age will be randomized to receive vaccine (30) or placebo (30).

Influenza Vaccine and Pneumococcal Vaccine
InfluenzaHuman1 morePrevious studies have demonstrated the immunogenicity and safety of the co-administration of the trivalent inactivated influenza vaccine (IIV3) with the polysaccharide pneumococcal vaccine (PPV) or pneumococcal conjugate vaccine (PCV). However, there is no direct comparison study that evaluates the immunogenicity and safety of IIV3 given concomitantly with PCV13 or PPV23 in the elderly. This study is intended to compare the immunogenicity and safety of concomitant administration in the elderly subjects.
