Bingo!!!
Have a HBsAb (hepatitis B surface antibody(anti-HBs)) titre done if in doubt. This will give you your immune status. This should be automatically done by your clinic with your history of immunization in 1998 prior to considering re-vaccination.
With that stated, CDC recommendation and literature states:
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 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.
Hope this helps.
