Why get vaccinated against certain diseases that have almost disappeared?

child getting vaccinated

As vaccination has virtually eliminated infectious diseases such as tetanus, poliomyelitis and diphtheria, it is often common to forget how dangerous they are.

The microbes (bacteria, viruses, toxins, parasites, etc.) responsible for these diseases still exist, and remain a threat to unprotected individuals, with the possible risk of an epidemic if the population is insufficiently vaccinated.

While the risk of contracting these diseases is low in some countries, importation remains a possibility. Travelers can contract them and spread them when they return. Vaccination is therefore essential, given the frequency of international travel and the seriousness of these diseases.

Lastly, getting vaccinated also helps protect others, in particular those that cannot be vaccinated for medical reasons.
