Estimation de l'impact épidémiologique de différentes options de vaccination BCG en France

BCG vaccination of high risk children seems to be an efficient strategy. However, its current effectiveness would depend on the capacity to maintain a high vaccination coverage in this population in the context of the abrogation of mandatory vaccination and the impending disappearance of BCG administered by multipuncture, which is the technique used in France for the vast majority of primo-vaccinations. Beyond the economical and epidemiological parameters, the decision will have to consider the operational, social and ethical issues raised by a vaccination strategy targeting children mainly of foreign origin.
