Brief Summary
The aim of this study is to evaluate the persistence of hepatitis A antibodies at 138, 150, 162, 174,186, 198, 210, 222, 234 and 246 months after subjects received their first dose of a 2 dose vaccination schedule of hepatitis A vaccine. This protocol posting deals with objectives \& outcome measures of the extension phase at year 11 to 20. No additional subjects will be recruited during this long-term follow-up.

Outcome Measures
Primary Outcomes (2)
Anti-hepatitis A Virus (Anti-HAV) Antibody Concentration
Concentrations given as geometric mean concentration (GMC) expressed as milli-international unit per millilitre (mIU/mL). \*\* = Regarding Month 234 data, please note that there were 5 subjects for whom serum sample tube was broken and thus due to risk of contamination the test were not performed. Hence these subjects were not included in the LT-ATP cohort for immunogenicity analysis at Month 234. $ = Regarding Month 246 data, please note there was 1 subject for whom serum sample tube was broken and hence scrapped by laboratory. Hence this subject was not included in the LT-ATP cohort for immunogenicity analysis at Month 246.
At Months 138, 150, 162, 174, 186, 198, 210, 222, 234 and 246
Number of Seropositive Subjects Against Hepatitis A Virus
A seropositive subject was a vaccinated subject whose concentrations for antibodies against hepatitis A virus (anti-HAV) were equal or above (\>=) the assay cut-off for seropositivity of 15 milli-international units per milliliter (mIU/mL). \*\* = Regarding Month 234 data, please note that there were 5 subjects for whom serum sample tube was broken and thus due to risk of contamination the test were not performed. Hence these subjects were not included in the LT-ATP cohort for immunogenicity analysis at Month 234. $ = Regarding Month 246 data, please note there was 1 subject for whom serum sample tube was broken and hence scrapped by laboratory. Hence this subject was not included in the LT-ATP cohort for immunogenicity analysis at Month 246.
At Months 138, 150, 162, 174, 186, 198, 210, 222, 234 and 246
Secondary Outcomes (7)
Anti-hepatitis A Virus (Anti-HAV) Antibody Concentration
Before additional vaccination, 14 days after additional vaccination and 30 days after additional vaccination

Limitations and Caveats
For 5 subjects at Month 234, serum sample tubes were broken. Due to risk of contamination, anti-HAV concentrations analyses were not performed for these subjects, who were excluded in the LT-ATP cohort for immunogenicity analysis at Month 234.
