Life course vaccination and healthy aging.

The authors notice the low vaccine coverage rate among European citizens and inventory the multiple reasons leading to the non-use of preventable infectious diseases vaccines in adults whose mortality consequences represent an important and unexpected burden of diseases. These facts are in close relation with the disruption of vaccine recommendations after the childhood vaccine program, the poor literacy knowledge concerning vaccines among the general population, but also unfortunately among physicians and other health care workers. Popular beliefs, fear of side-effects, fear of needles facilitated the constitution of active non-vaccine groups which conduct to the reappearance in non-vaccinated adults and with dramatic consequences of preventable childhood infectious diseases. This careful analysis of the current preventable infectious disease vaccine coverage in old adults leads to propose a life course vaccine programme including adult vaccinations as part of healthy aging as well as old adults' vaccine guidelines integrated in health prevention programs.
