Abstract

BACKGROUND
Hepatitis B is an important disease in South Korea because the prevalence is high. There are two officially granted hepatitis B vaccination schedules; 0, 1, 2 month schedule (not 0, 1, 2, 12 month schedule) and 0, 1, 6 month schedule. This study was performed to compare vaccination completion rate between the two schedules.
METHODS
The study subjects were all subjects who came to the City Medical Center to receive their first hepatitis vaccination dose from March to September, 1998. On odd numbered day, 0, 1, 2 month schedule was delivered and on even numbered day 0, 1, 6 month schedule was delivered. On the first visit, the data about general characteristics were collected via self administered questionnaire. Whether three vaccination doses were all received or not was ascertained by vaccination registration book. The subjects whose vaccination completion could not be ascertained by the book were called by telephone. The data were analyzed by Excel and SPSSPC.
RESULTS
Total collected cases were 822. Among them, 99 cases were excluded from analysis due to reasonable incompletion (11), incorrect inclusion (9) and impossible confirmation (79), which left 723 cases. General characteristics between two groups were not different except the existence of intrafamilial hepatitis carrier. The hepatitis B vaccination completion rate was higher in 0, 1, 2 month schedule (85.4%) than in 0, 1, 6 month schedule (76.1%) only in the cases without intrafamilial hepatitis B carrier member.
CONCLUSION
The completion rate of hepatitis B vaccination was higher in 0, 1, 2 month schedule than 0, 1, 6 month schedule in the cases without intrafamilial hepatitis B carrier member.
