Objective:

To assess vaccination coverage in children under seven years of age.

Materials and methods:

Study based on the Halfway National Health and Nutrition Survey (Ensanut MC 2016).

Results:

Full vaccination coverage in children <1 year was 51.7%, (range: 67.6% [pentavalent (PV)] to 93.9% [BCG]), in those aged 12-23 months was 53.9% (range: 68.5% [MMR] to 98.3% [BCG]) and in those 24-35 months was 63.2% (range: 85.3% [pneumococcal]) to 98.6% [BCG]). In children aged six years, the coverage of 1 MMR dose was 97.8% and 50.7% for two doses. Only 2.2% of six year olds were not vaccinated. Variables associated with incomplete schedule were age of 2-5 months, mother being under 20 years of age or maternal language indigenous.

Conclusions:

The vaccination program needs to improve recruitment of newborns and their follow-up until they complete their immunization schedule, taking advantage of the local contacts with health services to vaccinate them.
