Immunogenicity and Safety Study to Assess Influenza Vaccine Formulated With Haemagglutinin (HA) Antigen From Two Suppliers

29 août 2013 mis à jour par: Crucell Holland BV

Randomized, Parallel-group, Double-blind Multi-center Phase III Study to Assess the Immunogenicity and Safety of the 2010/2011-season Influenza Vaccine Formulated With Haemagglutinin (HA) Antigen From Two Suppliers, in Elderly and Young Adults

The purpose of this study is to assess the humoral immune response and safety of the parenteral formulation of the 2010/2011-season virosomal subunit influenza vaccine Inflexal V using two different HA antigen suppliers (AdImmune and CSL), in groups of young and elderly adults, using the EMA (European Medicines Agency) regulation as a guideline.

Aperçu de l'étude

Description détaillée

The objectives of this study are to evaluate the humoral immunogenicity and safety of the parenteral formulation of the 2010/2011-season influenza vaccine, Inflexal V, using HA antigen obtained from 2 different production facilities, and to compare the immunogenicity of both formulations to pre-defined EMA criteria for the annual relicensing of seasonal influenza vaccines. The evaluation will be done in young adults and elderly.
