Poor uptake of hepatitis B vaccination is common among health workers and clinical students who are at higher risk of hepatitis
B virus infection. This study assessed the knowledge of clinical students of the OAU, Ile-Ife about hepatitis B virus infection
and its modes of prevention. The descriptive cross-sectional study was carried out among all 594 clinical students of OAU using
a pretested self-administered semi-structured questionnaire. Data collected were analyzed electronically. Relationship between
independent and outcome variables were tested using Chi square test. Four hundred and thirty (72.4%) respondents correctly
identified four modes of transmission; which are use of contaminated needles, sexual intercourse, vertical transmission and
infected blood. Four hundred and seventy (79%) respondents reported vaccination as a mode of prevention of HBV infection
and 371 (62.5%) reported universal precautions. Only 23 (3.9%) listed post-exposure prophylaxis as a preventive measure. Of
all respondents, only 61.6% had ever received vaccine while only 39.2% of the respondents had received at least three doses
of HBV vaccine. Females were more likely to have received three doses of the vaccine compared with their male counterparts
(p<0.01). Clinical II students were more likely to have received three or more doses of vaccine compared with those in other
classes (p=0.024). The study concluded that the clinical students had poor knowledge of safe sexual practices and post-exposure
prophylaxis as preventive measures. The uptake of HBV vaccine was also poor. The significant correlates of vaccine uptake were
gender and the level of study of the respondents.
