While seeking medical research regarding Hepatitis B vaccine and various genetic populations, I found that within one year, "up to half of the subjects failed to maintain a titer", even after 3 doses of Hep B vaccine! [original source 1998 PDR]
See Drugs.com info which hasn't been "updated" from the original text of the Hep B package insert: http://www.drugs.com/drp/hepatitis-b-vaccine-recombinant.html
There is a bunch of subsequent research documenting concern about the "efficacy" of the Hep B vaccine over time.
"Many studies have probed for the reasons why subjects fail to develop adequate anti-HBs titers after hepatitis B vaccination."

"Hepatitis B vaccine has been reported to decline rapidly within the first year and more slowly thereafter."

"Among children who respond to the complete primary 3-dose vaccination series with anti-HBs concentrations of >10 mIU/mL, 15%–50% have low or undetectable concentrations of anti-HBs 5–15 years after the start of the vaccination series .
In adults, anti-HBs concentrations decrease rapidly within the first year after primary vaccination and more slowly thereafter. A decrease was noticed to a level of <10 mIU/mL in 7%–50% of vaccinated adults within 5 years after vaccination and in 30%–60% within 9–11 years after vaccination ."

Hepatitis B vaccine in some populations with suboptimal immunogenic responses, such as preterm infants, the elderly, smokers, obese individuals, and those with chronic liver or renal diseases, diabetes mellitus (DM) or human immunodeficiency virus (HIV) infection, the anti-HBs antibody titre declines rapidly in the first year and then gradually after 1 year.21
