Vaccines and Infectious Diseases in the Ageing PopuLation

Description du projet

Efficacité de la vaccination chez les personnes âgées

La vaccination est l’une des stratégies clés pour protéger les individus contre les maladies infectieuses. Cependant, l’avancement naturel de l’âge est associé à une détérioration du système immunitaire, ce qui nuit à l’efficacité des vaccins. Le projet VITAL, financé par l’UE, étudiera les facteurs responsables de la non-réponse immunologique et développera de nouvelles stratégies pour résoudre le problème. En utilisant une approche multidisciplinaire, les chercheurs associeront les profils immunitaires des personnes âgées aux réponses vaccinales, offrant ainsi des connaissances factuelles sans précédent sur l’efficacité des vaccins existants. Surtout, le projet fournira un cadre conçu spécialement pour la vaccination des personnes âgées dans le but de promouvoir un vieillissement en bonne santé.

Objectif

Today’s major challenge is to improve efficacy of vaccines to protect the growing ageing population against infectious diseases (ID). The VITAL project aims to address this challenge by assessing the ID burden and mechanisms of immunosenescence to provide evidence-based knowledge on vaccination strategies to establish healthy ageing. Links with existing projects containing data sources combined with novel data acquired through our extensive network
of data registries across Europe will result in a database of epidemiology, risk factors and burden of disease of both vaccine-preventable (VP) and potential vaccine-preventable ID. Crucial knowledge on factors that hamper immune responsiveness and in-depth analyses of immune compartments involved in inducing effective immune responses to different vaccines in the ageing host will be gathered. We will identify novel predictive, potentially universal immune profiles of vaccine responses using novel technologies, unique experimental models and (infection) cohorts of elderly subjects in which (bio)markers of frailty have already been identified. Novel strategies to address the problem of immunosenescence will be tested, in particular whether vaccination of middle-aged individuals can maintain proper memory immune responses in the elderly, to improve memory immunity before reaching old age. Using data on epidemiology of VPID and immune responsiveness, novel agent-based models will be developed to build a user- friendly tool to be used by health care professionals for optimal implementation of vaccination strategies for older people and to develop dissemination protocols for the obtained knowledge for the healthcare field. Finally, we will deliver a framework that forms the basis for designing, implementing and regularly updating vaccination schemes for the ageing population. Thereby, VITAL will initiate an important impetus to a more targeted immunization program for the elderly in Europe that will enhance healthy aging.
