Abstract:
The extent of HBV infection in the staff of a large hospital for the mentally handicapped was investigated. Nurses with direct patient contact were identified as a particular risk group and hepatitis B vaccination was offered to them. Of the 500 who received a full course of vaccination 96% had detectable antibodies 9 months after starting vaccination. High titres (over 1000 IU/l) were found in 59.4%. Females responded better than males and the response was age-dependent. In only 2 of 20 non-responders did lasting immunity develop with a fourth dose of vaccine. Antibody titre decreased rapidly in all vaccinees followed up. In vaccinees with an initial titre above 100 IU/l the decrease in titre could be reversed by a booster dose. Those with a titre below 100 IU/l had a variable response to the booster dose and lasting immunity developed in only a few. A recall system was started that predicts when a booster dose will be required to maintain a protective level of antibody. Servicing such a vaccination programme is not easy.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
