[The role of economic evaluation for the implementation of vaccination strategies].

The analysis described below tries to underline the major economic aspects of vaccination strategies both in childhood (polio, diphtheria, tetanus, H influenzae, measles, rubella, mumps, et) and in the elderly (limited to influenza control). As a result we could demonstrate that, in spite of the formal recognition of the paramount importance of prevention in general, and of vaccinal prevention in particular; vaccinations are at present very poorly considered by policymakers and politicians. This in contrast with the fact that the studies so far examined show that vaccinations are among the most productive interventions (lowest cost per year of life-year spared, very good cost-benefit ratio, thanks to the cases of diseases avoided). Such a convenience is highest when, in front of a given disease, the vaccinal strategy has been duly selected. Therefore, it is suggested that additional resources should be provided in the future to complete the framework and to increase the coverage of vaccinations, including the new offers against Varicella, N meningitidis and Str pneumoniae: and, in the future, against Rotavirus and HPV.
