Abstract

Objective. To evaluate and compare vaccination coverage among children aged 12-23 and 24-35 months living in localities with less than 100 000 inhabitants in Encuesta Nacional de Salud y Nutrición (Ensanut) 2012 and Ensanut 100k (2018). Materials and methods. Estimate of coverage with both surveys. Results. Between 2012 and 2018, according to proof and self-report, the coverage of the basic scheme was maintained in children aged 12-23 (51.6 vs. 60.2%) and 24-35 months (51.4 vs. 50.0%). Similarly, only with proof (53.9 vs. 51.3% and 52.8 vs. 44.2%). In children aged 24-35 months, the coverage of the reinforced basic scheme reinforcements with probative document and self-report (30.9 vs. 34.0%) and only with reinforcements (30.2 vs. 27.8%) was maintained. Coverage with second and third doses of hepatitis B in both age groups decreased; additionally, first dose of measlesmumps-rubella vaccine (SRP, in Spanish) and third dose of Pentavalent in children aged 24-35 months. Conclusions. Coverages were maintained by schemes, despite reductions in hepatitis B, pentavalent and SRP.
