Anti-HBc positivity means you have:

Explanation:
Anti-HBc is the antibody to the hepatitis B core antigen, which only appears after exposure to the virus. Since the vaccine contains only the surface antigen, immunity from vaccination does not generate anti-HBc. So a positive anti-HBc result means you have been infected with hepatitis B at some point—in the past or currently (acute or chronic). It can be present during acute infection, chronic infection, or after the infection has resolved, sometimes even in the window period when other markers are changing. In other words, anti-HBc signals prior exposure to HBV rather than immunity from vaccination.
