Objective: To estimate prevalence of complete vaccination sketch in children of ages of 12 to 47 months old in strata 1 and 2 into urbane zone of Cali in the year of 2002 according to biologics and the categories of socio-demographic variables of the family, the mother and child.
Methods: The research corresponded to a cross section survey. The sample size used in the estimation process was 4452 children, drawn from conglomerates combined with strata by means of probabilistic sampling. The information was analyzed with Epi-Info version 6.04, with the Csample module for complex samples analysis.
Results: The vaccination coverage with complete sketch for the first year was 65.8 (62.1-69.5), with significative differences for one and two strata (x2=42.4, p< 0.05). In the group of 12 to 47 months the belower coverages according to biologic were for anti-Haemphilus influenzae type B and anti-hepatitis B 71.8% (68.6-75) and 92.2% (90.1-94.3) respectively. Statistical association was found (test x2, p< 0.05) in comparing vaccination coverages with mother’s age, mother’s schooling, mother’s working time, family income and type of health system affiliation.
Conclusions: The vaccination coverages in the studied population for some biologics were below, bearing in mind that the rule established by Colombian Ministry of Social Protection is to keep coverages into a minimum of 95%.
