It is unknown how long immune protection will last after Hepatitis B vaccination, whether that varies between demographic groups or geographic areas or whether immunity is boosted by exposure in the community. Hepatitis B exposure frequently occurs as a teen or young adult. Many of those vaccinated at birth are now in that high risk age group. Charts were reviewed at the Fairbanks Youth Facility, a juvenile detention and treatment facility. Data were collected to assess protective immunity after vaccination and then grouped by demographic and geographic variables. Results revealed that Facility residents had lower percentages of immune protection compared to those in the literature. Research also showed that there were differences in ratio of immune protection, although no correlation was found between immune protection and ethnicity or geographic area. It was concluded that residents' protective immunity lessens over time and extra vaccinations were not initially effective in boosting immunity.
