In Italy, due to mass vaccination campaigns, some diseases - such as diphtheria or poliomyelitis - have practically disappeared. However, we continue to vaccinate against some of these diseases, as they are still present in many countries and could be reintroduced into the national territory, affecting people who are not actively immunized.
As a result of globalization, in fact, international travelers and goods traffic could facilitate the return of diseases that have not existed in Italy for some time, in addition to facilitating the spread of pathologies that have never been present.
