RESUMO
Tetanus toxoid (TT) vaccination during pregnancy has been proven as an effective preventative measure to reduce the incidence of maternal and neonatal morbidity and mortality worldwide. This study aimed to assess the determinants of TT vaccine uptake among pregnant women at two public maternity specialized hospitals in Sudan. A hospital-based cross-sectional study was conducted at two public hospitals, Omdurman Maternity Hospital and Al Saudi Hospital in Omdurman, Khartoum State, in Sudan from February to April 2020. Logistic regression analysis was carried out to identify factors associated with receiving three or more doses of the TT vaccine among pregnant women, presented as odds ratios, with p-values < 0.05 considered significant (at a 95% confidence interval). The study recruited 350 pregnant women, with 313 participants included in the analysis. This study found that only 40% of the pregnant women had received three doses or more of the TT vaccine. Pregnant women who attended Al Saudi Hospital were less likely to be vaccinated with the recommended dose of the TT vaccine in districts at high risk (received ≥3 doses) compared to those who attended Omdurman Hospital [OR = 0.49 (95% C.I. 0.29-0.82), p-value < 0.05]. Furthermore, the number of children at home was a significant predictor of the mothers' immunization status as those with five children or more were ten times more likely to be vaccinated with three doses or more [OR = 10.54 (95% C.I. 4.30-25.86), p-value < 0.05]. We conclude that this low rate of TT vaccine uptake found in this study among pregnant women increases the number of newborn babies susceptible to contracting neonatal tetanus. The findings of this study should be considered in the development of communication strategies targeting and prioritizing at-risk groups to increase TT vaccine uptake among pregnant women in Sudan.
RESUMO
Objective: This study aims to explore vaccine information-seeking behavior and its determinants among pregnant women in Khartoum state, Sudan. The findings from this study will be used to inform further development of policies and interventions in Sudan to increase vaccine acceptance and demand. Methods: A hospital-based cross-sectional study was conducted in two public hospitals, Omdurman maternity and AL-Saudi hospitals in Omdurman, Khartoum state, from February to April 2020. Results: We interviewed 350 pregnant women in the two hospitals. Our findings showed that one-third of pregnant women (35.7%) searched for information about vaccines. The vast majority searched for this information before pregnancy and during pregnancy (34.4 and 59.2%, respectively). They primarily searched for topics related to vaccine schedules and vaccine side effects (28.8% for each). The main sources of vaccine-related information consumed by pregnant women were healthcare professionals, particularly doctors (40%), and the internet (20.8%). Findings showed that a high level of education was associated with a greater likelihood of searching for additional vaccine information. Moreover, those who perceived their family to have a high income were more likely to search for information. Additionally, pregnant women with low confidence in vaccines were more likely to be involved in searching for additional vaccine information. This highlights the need for high-quality, easily accessible information that addresses their needs. Conclusion: Our findings showed that confidence in vaccine influences seeking for relevant information. We recommend the development of client-centered communication interventions to help increasing vaccine confidence and consequently vaccine acceptance and demand.
