NCT06110741

Brief Summary

In this study, the poly vaccination of military personnel prior to deployment will be analyzed in terms of central, peripheral and long-lasting changes in innate immunity. Analysis of monocyte immune training induced by vaccination will provide a better understanding of the indirect effects of vaccination and their persistence over time.
