Q: I was vaccinated several years ago. Should I periodically be tested for my hepatitis B antibody level, and should I have a booster shot?
A: Current data show that vaccine-induced hepatitis B surface antibody (anti-HBs) levels may decline over time; however, immune memory (anamnestic anti-HBs response) remains intact indefinitely following immunization. Persons with declining antibody levels are still protected against clinical illness and chronic disease. For dental and other health care workers with normal immune status who have demonstrated an anti-HBs response following vaccination, booster doses of vaccine are not recommended nor is periodic anti-HBs testing. Note that all dental offices should maintain the hepatitis B immunization records for their staff including declination statements if applicable.
