Predictors of Hepatitis B Virus Infection Vaccine Hesitancy Among Pregnant Women Attending Antenatal Care at Lubaga Hospital, Kampala, Uganda.

Abstract

BackgroundWhile hepatitis B virus infection may be seen as a global threat within the medical and scientific community, primary prevention via vaccination remains the most effective approach towards breaking the chain of transmission of HBV infection. However, vaccination uptake in Uganda has been modest despite a very endemic national figure resulting from the vertical transmission of this infection. This study assessed the predictors of HBV vaccine hesitancy among pregnant women attending Antenatal clinic in Central Uganda.MethodologyA hospital-based cross-sectional study employing a five-sectioned pretested interviewer-administered questionnaire was conducted to obtain data from 385 consenting pregnant women. Responses for the antecedent variables were transformed into weighted aggregate scores using SPSS version 26. Multivariable logistic regression analysis was employed to ascertain the predictors of HBV vaccine hesitancy with the cut-off for hypotheses set at 5% level of significance.ResultsThe majority of the respondents (59%) were between the ages of 18 and 28 years. Women with secondary educational attainment were predominant (42.3%). The respondents had mean scores of 5.97±6.61, 17.10±18.31, and 12.39±13.37, respectively, computed for knowledge of HBV infection, perception, and behavioral skills towards HBV prevention. Regarding vaccine hesitancy, three-quarters of the women (74%) hesitated to uptake HBV vaccine. While negative significant associations exist between marital status (AOR = 0.47, 95% CI = 0.22–1.01), knowledge (AOR = 0.79, 95% CI = 0.70–0.89), behavioral skills (AOR = 0.88, 95% CI = 0.81–0.95) and vaccine hesitancy, level of education (AOR = 1.88, 95% CI = 1.08–3.27) and perception (AOR = 1.11, 95% CI = 1.05–1.18) on the other hand, positively predicted vaccine hesitancy.ConclusionThe findings reported an extremely high degree of HBV vaccine hesitancy among the expectant mothers discovered to be linked with marital status, educational attainment, HBV-specific knowledge, perception and behavioral skills. This necessitates targeted health education for married women with lower educational attainment to improve their knowledge which will in turn shape their perception and behavioral skills towards satisfactory uptake of HBV vaccine.
