The independent variables were: population size and family health strategy covering. Data were analyzed through the statistical program SPSS 17.0 by means of descriptive association and analysis tests. Results: In the analysis of vaccination coverage by municipality low homogeneity in the pregnant and children groups was found. 316 (32%) did not have coverage for pregnant women, 17 (2%) for children and 41 (4.8%) for the elderly. Associations of context variables (coverage strategy of family health and population size) to reach minimum coverage were not identified. Conclusion: Although the state has appropriate vaccine coverage, coverage homogeneity for pregnant women and children remains low.
