Introduction:

Vaccination is the most effective preventive weapon for communicable diseases known to humanity. It is the responsibility of primary health care professionals to ensure that the administered vaccines are truly immunizing. Likewise, it is important that vaccination be accepted without hesitations, especially in the current epidemiological situation.

Objective:

To describe the social, economic and ethical implications related to the existence of theoretically nonimmunizing vaccines.

Methods:

The results of an educational intervention program in pediatric ages at 13 de Marzo Policlinic were used. The Wilcoxon signed-rank test was used, with a confidence index of 95 %.

Results:

Initially, an inadequate level of knowledge predominated, which later improved significantly. Forty-eight unvaccinated children and 29 unimmunized children recovered.

Conclusions:

There is no correspondence between vaccination coverage and immunization. False contraindications for vaccination are established as correct. The educational intervention was effective, while the relevance became evident for undergraduate and postgraduate programs to improve the training of professionals and the quality of professional performance.
