    Abstract:
    Lack of knowledge and negative attitudes were the main reasons for refusal, in a vaccination programme against hepatitis B using plasma-derived vaccine which was offered to the hospital personnel of Chulalongkorn University Hospital, Bangkok. Therefore, to ascertain whether an educational intervention among hospital personnel is effective in modifying acceptance of the vaccine, a quasi-experimental design (using a before and after approach) was used to compare the knowledge, attitudes and acceptance rate of hepatitis B vaccination among 1,915 hospital personnel. After dissemination of information, knowledge and attitudes improved significantly, and acceptance rates were increased from 56.9% to 77.7% (P < 0.0000). More specific educational efforts should be started before launching vaccination programmes of this kind in order to increase acceptance. The potential for infection with hepatitis B vaccine is a serious threat to all health care workers, especially among hospital personnel frequently exposed to blood and its products. Chulalongkorn University Hospital is a 1400-bed university teaching hospital in Bangkok. Recognizing the risk of infection, it was planned to offer free vaccinations against hepatitis B using the Hevac B Pasteur plasma-derived vaccine to all hospital personnel. A pre-vaccination program survey of 1492 nursing personnel found the initial acceptance rate to be only 49.7%, with 39.2% undecided and 11.1% planning to not accept. 65.7% of the remaining 1299 personnel planned to accept the vaccine, with the lowest rate among physicians at 48.2%. Lack of knowledge and negative attitudes were the main reasons for refusal to accept the vaccine. The authors used a quasi-experimental before-after design to explore whether an educational intervention among hospital personnel would be effective in increasing the acceptance of the vaccine. Findings are based upon comparisons of the knowledge, attitudes, and acceptance rate of hepatitis B vaccination among 1915 hospital personnel. Levels of knowledge and attitudes were found to improve significantly after the information was disseminated, with acceptance rates increasing from 56.9% to 77.7%. This success highlights the potential merit of implementing targeted educational interventions before launching vaccinations programs of this kind in other settings.
