Determinants of TT vaccine completion among mothers who gave birth with in the past six months in Gozamn District, Ethiopia

• TT vaccine completion among recently delivered mothers remains suboptimal. • Higher parity is positively associated with TT vaccine completion. • Information from healthcare professionals improves TT vaccination uptake. • More than four ANC visits significantly increase TT vaccine completion. • Strengthening ANC and provider communication can enhance maternal TT coverage. Tetanus toxoid (TT) vaccination is essential for preventing neonatal tetanus and ensuring maternal health, particularly in resource-limited settings. Despite its importance, TT vaccine completion rates remain low in some regions, including Ethiopia. This study aims to identify the factors influencing TT vaccine completion among mothers who gave birth within the last six months in Gozamn district. A community-based cross-sectional study was conducted between April 1 and April 25, 2022, in Gozamn district. A total of 831 mothers who gave birth in the past six months were selected using a two-stage stratified sampling method. Data were collected through a structured, interviewer-administered questionnaire. Descriptive statistics and bivariable and multivariable logistic regression analyses were performed using Stata version 17 to identify factors associated with TT vaccine completion. Factors such as higher parity, receiving information from healthcare professionals, and having more than four antenatal care (ANC) visits were found to be significantly associated with higher TT vaccine completion. Women with higher parity, those informed by health professionals, and those attending more than four ANC visits were more likely to complete the TT vaccine. This study highlights the critical role of parity, healthcare provider communication, and ANC visits in increasing TT vaccine completion. Efforts to improve vaccine uptake should focus on increasing access to healthcare information and services, especially among women with fewer ANC visits and lower exposure to healthcare professionals.
