Hepatitis B virus is the world's most common blood borne viral infection. Occupational risk of Hepatitis B infection is well known in medical and dental workers especially during the professional training period. The present study was conducted among medical students of a Medical College in Delhi to assess their knowledge regarding Hepatitis B. A questionnaire was administered to the first, third and final year medical students regarding Hepatitis B vaccine, disease, and mode of spread, sequel and prevention. The knowledge regarding all aspects was maximum amongst the final year students as compared to first and third years. Knowledge regarding the booster dose of vaccine, transmission through formites, universal precautions for prevention was not good. There is need for strengthening in these areas and training in these should be started at the earliest.
