Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Out of the 666 subjects who received at least one vaccine dose in primary study (NCT00196937), one subject was erroneously invited for the Year 5 visit of this study, but was not eligible and was excluded from all Year 5 analyses. Further, a total of 158 subjects missed the Year 5 visit. Therefore, a total of 507 subjects are reported for year 5.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Some subjects who came for the Year 5 timepoint did not show up for the Year 6 or Year 7 timepoints, while not all subjects who entered the Year 6 or 7 timepoints were present for the Year 5 timepoint.
