In order to reach vaccination coverage in adults, the elderly and in high risk subjects, a tight network of collaboration between preventive medicine specialists and general practitioners must be created in the same way that they must be created with pediatricians. In fact, this strategy has brought about very high coverage rates in childhood vaccinations. The solution to propose once again would thus be to develop partnerships between the protagonists of the network (community health district, department of prevention, general practitioners, primary care physicians) so that synergies may be created which permit the realisation of common and specific training programs.
