Further study details as provided by Novartis:

Primary Outcome Measures:
  • Antibody (Ab) response data at 24-months after the last injection given in study V98P1 GMCs, GMRs and associated 95% confidence intervals will also be determined [ Time Frame: 24- months post last injection from V98P1 ]

Enrollment: 50
Study Start Date: January 2010
Study Completion Date: October 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
