How would the Hepatitis B serology appear for an immunized individual?

For an immunized individual, Hepatitis B serology would show positive anti-HBs antibodies, indicating that the person has developed immunity to the virus due to vaccination. This immunity is a result of the body producing specific antibodies against the Hepatitis B surface antigen (HBsAg) following the vaccination process.

In the case of a vaccinated individual, the expectation is that the other serological markers, such as HBsAg or anti-HBc (antibodies against hepatitis B core antigen), are negative. The presence of positive anti-HBs without other positive serologic markers confirms that the person has been immunized, rather than having been exposed to the virus.

The other options do not accurately reflect the serology of an immunized person: showing negative for all antibodies would suggest no immunity or previous exposure; being positive for all Hepatitis antibodies would indicate active infection or past infection; and being only positive for Hepatitis B core antibody would imply a previous infection with the virus, which would not be the case for someone who has only been vaccinated. Therefore, the correct depiction of the serology for an immunized individual is positive anti-HBs antibodies with other serology negative.
