Detailed Description:

The base study V503-002 is a 12-month study that is collecting safety and immunogenicity information for six months following the subjects' third dose of study vaccine and is expected to conclude in 2011.

An optional extension study (V503-002 EXT1) will collect safety and immunogenicity information through Month 36. No study vaccine will be administered in the extension study. Subjects enrolled in the 16- to 26-year-old cohort in the base study will not be included in EXT1.

An optional second extension study (V503-002 EXT2) will collect long-term safety and immunogenicity information through approximately 10 years. No study vaccine will be administered in the extension study. Subjects enrolled in the 16- to 26-year-old cohort in the base study will not be included in EXT2.
