Vaccine Reaction Clinical Trial
Official title:
Effect of High-Dose Quadrivalent Influenza Vaccine (Efluelda®) Versus Standard-Dose (QIV-SD), in Subjects 65 Years of Age and Older on Innate Immunity, Including Gene Expression
The purpose of the study is to evaluate innate and adaptive immunity following QIV-HD vaccination compared to QIV-SD vaccination in people 65 years of age and older.
The hypothesis is that higher dose of antigen can increase the intensity and the quality of innate immunity, as the adaptive humoral and cellular responses. In this study, the objectif is to evaluate innate and adaptive immunity following QIV-HD vaccination compared to QIV-SD vaccination in people 65 years of age and older. Modifications of early blood molecular (transcriptome) and cellular (blood phenotyping) signatures within the first 24 hours following vaccination will be investigated. The association between early gene signature and late influenza-specific humoral immune responses weeks/months after vaccination will be also assessed. This study is a hase IV, randomized, open-label, active-controlled, multi-center study comparing the immune response induced by QIV-HD vaccine (intervention) and QIV-SD vaccine (control). ;
