Correct answer: B

She needs a blood test for anti-HBs antibody level: if ≥10 mIU/ml, she is immune and can commence clinical duties. If <10 mIU/ml (non-responder or waned immunity), she needs a booster dose followed by repeat testing in 4-8 weeks. If still <10 after booster, a full re-vaccination course (3 doses) is given. If still a non-responder after two full courses (approximately 5-10% of the population), she should be counselled that she remains susceptible to HBV, must take extra precautions with sharps, requires HBIG after any significant exposure, and in some jurisdictions may have restrictions on exposure-prone procedures
