SUMMARY:

ABSTRACT: Introduction: The National Immunization Program (PNI) through the vaccines of the basic schedule has been promoting the eradication, elimination, or reduction in terms of incidence, severity, and lethality of various infectious diseases. This fact can be proven with the eradication of smallpox in 1980 and the elimination of polio in the country in 1994. However, in recent years there has been a decline in vaccination coverage (VC), leading Brazil to face significant outbreaks of wild yellow fever and measles. These VC indicators are mostly based on the number of doses applied contained in the information system and do not allow the analysis of factors that lead to non-vaccination, thus, the household vaccination survey is essential for adequate monitoring of vaccination programs, identification of children who are delayed on their vaccination schedule and the factors that lead to this non-vaccination. Objective: The present study estimated vaccination coverage and analyzed the factors associated with incomplete vaccination schedules in children from six months to under five years old in Primary Health Care Units (PHCU) 01 and 04 of Riacho Fundo II in the Federal District. Method: A standardized questionnaire answered by the child's mother or guardian and photographic record of the vaccination card were used. A total of 162 probabilistically selected people were interviewed in the PHCU territories. The study estimated vaccination coverage, the proportion of incomplete vaccination schedules, and used Prevalence Ratios (PR) and their confidence intervals (CI 95%) to estimate the associations between independent variables and the outcome in question (incomplete vaccination schedules), for this purpose, a Poisson regression with robust adjustment was employed. Results: 80% (130/162) of the children evaluated had a complete vaccination schedules. However, none of the vaccines evaluated reached the vaccination coverage recommended by the Ministry of Health, considering the doses administered correctly in terms of age and interval between doses. The results ranged from 46.91% (CI 95%: 39.04%-54.90%) to 77.16% (CI 95%: 69.92%- 83.38%) for the pentavalent and rotavirus vaccines, respectively. Considering only valid doses, that is, doses applied from the recommended minimum age and with an interval equal to or greater than the recommended one, the results were more favorable, ranging from 93.29% (CI 95%: 88.80%- 96.73%) to 99.39% (CI 95% : 96.61%- 99.98%), for the varicella and pneumococcal vaccines, respectively. Factors associated with incomplete vaccination schedules were age under 2 years (adjusted PR: 2.55, CI 95% -1.53-4.24), indication of difficulties arising from the Covid-19 pandemic by those responsible (adjusted PR: 2.71, CI 95% - 1.51-4.86), and a negative response when asked if all vaccines were administered in the same location (adjusted PR: 1.97, CI 95% - 1.13-3.44). Conclusion: The results showed that vaccination coverage did not reach the goals recommended by the Ministry of Health, although it was more favorable when considering only valid doses. In addition, age under 2 years, difficulties arising from the Covid-19 pandemic, and lack of vaccination in the same location were identified as factors significantly associated with incomplete vaccination schedules. These findings highlight the importance of understanding local factors and knowing vaccination coverage to achieve the goals recommended for VC.
