Analysis of factors influencing vaccine uptake: perspective from Spain.

Although each of the 17 Autonomous Regions in Spain has their own vaccination policies, factors influencing vaccine uptake do not differ considerably among them. Knowledge of vaccine preventable diseases, awareness that the diseases prevented by vaccinations are serious or very serious, awareness that vaccinations are not generally associated with serious adverse events, cost-free status and satisfaction with our computerised immunization registry, are the elements which influence vaccine uptake in our country.
