The objective of this article is to ana-lyze the spatial distribution of Hepatitis B vaccine (HBVAC) of pregnant women. This is a cross-sec-tional study carried with 266 puerperae. The HB-VAC record was obtained through the prenatal care booklet. The spatial scanning technique was used to detect a cluster of risk for the presence or absence of an HBVAC record. After this cluster identification, the individual and environmental variables were compared between the Coverage Areas of Basic Health Units (CAs-BHUs). The mean prevalence of non-HBVAC was 88.34%. Scan spatial scan analysis observed a cluster of a high prevalence of puerperae with a HBVAC re-cord. Comparative analyses have shown that paid work and the number of prenatal visits are pos-itively associated with an HBVAC record. Given the above, this work brings a reflection on possible disparities with other CAs-BHUs, besides the influence of the environmental perspective. It should be emphasized that the vaccination situation is influenced not only by factors intrinsic to the in-dividuals. However, in this study, the results indi-cate that individual variables are predominant-ly mandatory in the decision of HBVAC uptake among pregnant women.
