Abstract:
ABSTRACT
Hepatitis B is now a major global health problem. Clerkship students are at
risk of Hepatitis B Virus (HBV) infection through accidental exposure to blood and
body fluids due to inexperience and lack of ability in procedures with patients. There
is still no regulation of hepatitis B screening and vaccination for clerkship students in
Faculty of Medicine Riau University. This descriptive research aimed to identify the
hepatitis B vaccination status and post-vaccination anti-HBs titer of clerkship
students at Faculty of Medicine Riau University in November 2011 period. About 78
were participated, chosen by simple random sampling method. Students were
managed to fill the form of the vaccination history and their sera were taken to assess
the anti-HBs titer by ELISA examination. Of all the 78 students, 39 (50%) had
received hepatitis B vaccine. Among vaccinated students, a total of 64,1% had the
protective anti-HBs titer (≥10 mIU/mL) and 35,9% had the non-protective titer.
Negative result for anti-HBs examination was found in 66,7% of students who had
been vaccinated by age less than 20 years and in 9,5% of students who got the
vaccine by age 20 years and older.
