In a study of 497 injection drug users who had isolated presence of antibody to hepatitis B core antigen (anti-HBc) at the time of enrollment, 404 (81%) retained this condition after a mean of 49 months of follow-up, during which time no new hepatitis B surface antigen marker was detected. These findings support the hypothesis that patients with isolated presence of anti-HBc have strong resistance to reinfection and do not need vaccination.

Abstract
In a study of 497 injection drug users who had isolated presence of antibody to hepatitis B core antigen (anti-HBc) at the time of enrollment, 404 (81%) retained this condition after a mean of 49 months of follow-up, during which time no new hepatitis B surface antigen marker was detected. These findings support the hypothesis that patients with isolated presence of anti-HBc have strong resistance to reinfection and do not need vaccination.
