<p>We conducted a cross-sectional descriptive study among 352 consenting pregnant women attending antenatal care at the Federal Medical Center and Adamawa State Specialist Hospital in Yola. We collected socio-demographic and obstetrics history data from the pregnant women using a semi-structured interviewer-administered questionnaire. We scored the knowledge questions with a maximum score of 32 points and a minimum of zero. A knowledge score of &lt;50% was regarded as poor knowledge while a score of 50-69.9% was regarded as fair and a score of ≥70% was regarded as good knowledge. We collected blood samples and tested for HBV using Hepatitis B surface antigen (HBsAg) rapid diagnostic test kits. We analyzed data using proportions, odds ratios (OR), and confidence intervals (CI), with the P-value at ≤ 0.05.</p>
