Milieu intérieur : Defining the boundaries of a healthy immune response for improved vaccination strategies

Darragh Duffy 1, *
Abstract : Immune responses in human populations are highly variable, with this variability presenting challenges for vaccine design. As such a better understanding of the factors that determine this variability will help in the development of precision vaccination strategies. The Milieu Interieur consortium was established to address this challenge through a definition of the normal boundaries of a healthy immune response, and the characterization of their genetic and environmental determinants. To do this we have implemented standardized tools for monitoring functional immune responses at the proteomic and transcriptional level, which have been applied to a 1,000 healthy donor cohort. This approach has recently allowed us to quantify the extent of genetic control of cellular variability and transcriptional responses to infection. Initial findings on the influence of age, sex, and genetics may already be included in considerations for improved vaccine development, and ongoing analysis will further define the factors behind inter-individual variability in diverse immune responses. This approach will help to guide the development of the next generation of vaccines that will take into account differences in populations and eventually individuals.
