A cross-sectional study was conducted based on the secondary analysis of the Demographic and Family Health Survey (ENDES) 2019, with the objective of estimating the incomplete coverage of PTD and determining the factors associated with it in infants aged 12 to 23 months in Peru. Pearson's chi-square test was used for the bivariate analysis and the magnitude of the association was estimated using the crude (PRc) and adjusted (RPa) prevalence ratios. Incomplete DPT coverage was 12.4% (CI 11.88-14.79) for the entire population studied. Infants in the third order of birth or more (PRa: 1.37; CI 1.01-1.84) and infants born by non-institutionalized delivery were more likely than children whose delivery was institutionalized (PRa; 1.70; CI 1.15-2.54). The probability of having incomplete coverage decreased by having 6 or more prenatal check-ups (PRa; 0.58; CI 0.46-0.73), as well as living in rural areas compared to living in urban areas (PRa; 0.64; CI 0.48-0.85). Incomplete DPT vaccination in infants aged 12 to 23 months in Peru has a high level (> 10%), placing this population group at risk of suffering from these immunopreventable diseases and triggering outbreaks and epidemics in the community. The factors associated with incomplete vaccination are related to lower socioeconomic conditions and limited access to health services, which is why it is necessary to focus the interventions of the National Immunization Health Strategy to reverse this situation.
