ABSTRACT
OBJECTIVE: To evaluate the coverage of the programme of control and coverage of Hepatitis B among children doing their 7th year of EGB (basic) in Navarra. DESIGN: Descriptive study. SETTING: School centres in Navarra. PARTICIPANTS: 7th-year EGB students in the 1992-3 school year. INTERVENTION: Vaccination of the susceptible population with three doses of anti-HB vaccine on the 0-1-6 months pattern. MEASUREMENTS AND MAIN RESULTS: Nominal data of children vaccinated were obtained from 171 schools out of a total of 185 (92.43%). For the rest of the centres, it is known only that vaccinations took place within the School Health Programme. The susceptible population was 6,955 children, of whom 97.8% received the first dose, 97% the second and 95.6% the third. The most common cause of non-vaccination in these children was lack of parental authorization, which reached 1.8%. CONCLUSIONS: A School Health programme, which is well-established and closely linked to the Primary Care network, together with a broad diffusion of information about the adolescent Vaccination Programme were key to its widespread introduction and the excellent coverage attained.
