Place and Duration of Study: The Aga Khan University Hospital, Karachi from March 2003 to May 2003. patients and Methods: Three hundred and ninety-three health care workers were interviewed after taking verbal consent using a self-administered questionnaire by convenience sampling. A sample size of 385 was calculated, using 5% level of significance, margin of error as 5% and an expected prevalence of 50%. Descriptive statistics like percentages, mean and range were obtained. Results: A total of 393 respondents, (age range 19-59 years) were interviewed. Amongst them 86% were completely vaccinated, 12% had incomplete vaccination and 2% didn’t have even a single dose. Needle stick injuries were highest amongst those health care workers who had complete vaccination. Conclusion: Despite the availability of free vaccination, a target of 100% coverage has not yet been achieved. All health care workers should be motivated and ensured for vaccination. Regular educational campaigns for health care workers are needed to increase vaccination compliance.
